Answer:
D
Explanation:
I just took this quiz so you are welcome
Codons are similar, both prokaryotic or eukaryotic cells have the same type of codons.
Codons are similar, both prokaryotic or eukaryotic cells have the same type of codons. Codons of both cells start with the same point or material but end with different point or materials. These codons are also different in these cells such as Prokaryotic codons usually specify different amino acids than those of eukaryotes.
The translation of codons is mediated by tRNAs in eukaryotes, but translation requires no intermediate molecules such as tRNAs in prokaryotic cells. Prokaryotic codons have contain different bases than that is present in eukaryotic cells so we can conclude that codons of both cells are similar in characteristics.

Can convection take place in the water if it is heated at the top?
Answer: If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then the unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.
This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.

What’s the correct mRNA sequence from the DNA strand: TAC GCC CGA ATC
A. ATG CCG GCU TAG
B. AUG GCC GCU UAG
C. AUG CGG GCU UAG
D. AUG CCG GCT UAG
E. ATG CCG CGT TAG
Answer:
C. AUG CGG GCU UAG
Explanation:
This works the same as a normal DNA strand, A=T, C=G, except for one difference. Thymine is not an mRNA base, instead it is Uracil. Therefore, if there is an A, you would typically replace it with a T, but for mRNA you will replace it with a U. Keep in mind you will still replace the T in the DNA strand with an A in the mRNA strand :)

The table that provides the best approximation of an organism's DNA base composition according to Chargaff's research is the third table.
Chargaff's researchChargaff, in his research, found that the ratio of purine to pyrimidine bases for virtually all DNAs is constant.
Specifically, Chargaff found that the ratio of Adenine base to Thymine base is always the same. In the same vein, the ratio of Cytosine to Guanine base is always the same.
Thus, if a DNA contains a 21.2% Adenine base, the percentage Thymine base of in the DNA will also be 21.2%. This is for a fact.
In addition, the remaining percentage bases of the DNA must be shared equally between Cytosine and Guanine.
Only table 3 fulfills these conditions.

a) Identify this moleculea
The chemical equation shown represents photosynthesis.
Carbon dioxide plus A plus light with a right pointing arrow towards B plus oxygen. The arrow has an x above it.
What is the role of substance A in photosynthesis?
It stores chemical energy for plants and animals.
It traps light energy and converts it into chemical energy.
It combines with carbon dioxide and light to form glucose.
It combines with carbon dioxide and light to form hydrogen.
Based on the given chemical equation, the role of substance A in photosynthesis is "It traps light energy and converts it into chemical energy."
In photosynthesis, substance A refers to chlorophyll, which is the pigment found in chloroplasts of plant cells. Chlorophyll plays a vital role in capturing light energy from the sun.
It absorbs light across a range of wavelengths, primarily in the red and blue regions of the visible spectrum, while reflecting green light, which gives plants their characteristic color.
When chlorophyll absorbs light energy, it initiates a series of chemical reactions within the chloroplasts.
This energy is utilized to power the conversion of carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2) through a process called photosynthesis.
Therefore, substance A, chlorophyll, traps light energy and facilitates the conversion of light energy into chemical energy, which is stored in the form of glucose.
This stored energy serves as a vital source for plants and is also utilized by animals through the consumption of plants or plant-eating organisms.

92ml 3.0 fl oz what is the ratio
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

What are the stages of bee development (eggs,larvae,pupae)
The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.
The stages of bee development are:
1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.
2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.
3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.
4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.
It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of fish and four that were not. As they studied the ponds, they noted that the areas around the four fish-populated ponds showed decreased populations of dragonflies and dragonfly larvae, whereas the four without fish showed abnormally large populations of dragonflies and larvae. Dragonflies feed on bees, butterflies, and other pollinators.
Required:
Predict what would happen to the rate of pollination of flowers in a field next to a pond with no tish.
Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.
Explanation:
POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.
From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.
It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.

The set of symptoms and treatment options of Human genetic disorders, are Cystic Fibrosis (CF), Down Syndrome (DS), Hemophilia, Huntington's Disease (HD) and Sickle Cell Disease (SCD)
There are numerous human genetic disorders, each with its own unique set of symptoms and treatment options. Here are several examples:
Cystic Fibrosis (CF): CF affects the respiratory and digestive systems. Treatment involves a combination of airway clearance techniques, medications to thin mucus and control infections, and enzyme replacement therapy to aid digestion.
Down Syndrome (DS): DS is caused by the presence of an extra chromosome 21. Treatment focuses on managing associated health conditions such as heart defects, hearing loss, and cognitive impairments. Early interventions, such as speech and physical therapy, can help individuals with DS reach their full potential.
Hemophilia: Hemophilia is a bleeding disorder characterized by a deficiency of clotting factors. Treatment involves regular infusion of the missing clotting factor to prevent bleeding episodes. Advances in gene therapy offer potential long-term solutions by introducing the missing gene into the patient's cells.
Huntington's Disease (HD): HD is a progressive neurological disorder. Currently, there is no cure for HD, but medications can help manage symptoms such as movement problems and psychiatric symptoms. Supportive therapies, including physical and occupational therapy, can enhance quality of life.
Sickle Cell Disease (SCD): SCD is an inherited blood disorder. Treatment includes pain management during crises, regular blood transfusions, and medications to prevent complications. Stem cell transplantation can be a curative option for some patients.

what is the resting phase of the cell cycle called?
A. Prometaphase
B. Mitosis
C. Interphase
The resting phase of the cell cycle is called interphase.
Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.
This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.
Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

A student astronomer went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram above. The light part of the Moon appeared to get smaller over time. Why did this happen?
Answer:
The light part of the Moon appeared to get smaller over time because of the change in the relative position of the Moon, the Sun, and the Earth. This is known as the lunar phase. The changing appearance of the Moon from the Earth's perspective is caused by the Moon's orbit around the Earth and the position of the Moon and Sun relative to the Earth. The Moon's phases are caused by the angle between the Moon, Earth, and Sun changing, as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, the side facing the Earth is not illuminated by sunlight, so it appears dark, and this is called a new moon. When the Moon is on the opposite side of the Earth from the Sun, the entire side of the Moon facing the Earth is illuminated by sunlight, so it appears full, and this is called a full moon. As the Moon moves in its orbit, the angle between the Sun, Earth, and Moon changes, causing the illuminated portion of the Moon visible from the Earth to change, leading to different lunar phases.

Answer:
1. Hot spot
2. To explain the causes of continental movement
3. Move through different materials
4. Separated from the mantle by a layer of water. (Not a good answer, but the other two are entirely wrong!) It is because of density
5. The largest layer between the crust and outer core
Explanation:
Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving.
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. Anomalously hot areas slow down seismic waves. Seismic waves move more slowly through a liquid than a solid.
Continental crust floats higher in the mantle than ocean crust because of the lower density of continental crust.
The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84 percent of Earth's total volume.

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.
Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.
The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.
Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.
Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.
