Answers
The role of DNA production is not performed by the rough endoplasmic reticulum nor the smooth endoplasmic reticulum.
Endoplasmic reticulum (ER) is a complex organelle that appears like a maze of flattened sheets, sacs, and tubules inside the cytoplasm of eukaryotic cells. It is a type of organelle that is common to eukaryotic cells. The endoplasmic reticulum is divided into two main types: Rough endoplasmic reticulum and Smooth endoplasmic reticulum.
Role of Rough endoplasmic reticulum:Rough endoplasmic reticulum is abundant in cells that generate huge quantities of protein. The protein is first produced in the ribosomes, which are associated with the RER. The proteins are then modified and sorted in the RER, with some being dispatched to the Golgi apparatus via vesicles. The role of rough endoplasmic reticulum (RER) is to perform the following tasks:
Protein synthesis and foldingProtein modification, sorting, and dispatching to their final destination via vesicles.Role of Smooth endoplasmic reticulum:Smooth Endoplasmic Reticulum is especially abundant in cells that are involved in lipid metabolism, such as liver cells. It is also abundant in cells that produce steroid hormones, such as the adrenal cortex. It also plays a role in the detoxification of drugs. The role of smooth endoplasmic reticulum (SER) is to perform the following tasks:
Lipid synthesis, including the synthesis of phospholipids and steroidsMetabolism of carbohydratesDrug detoxificationCalcium ion storageThe role of DNA production is not performed by the rough endoplasmic reticulum nor the smooth endoplasmic reticulum.

List one abiotic and one biotic factor that humans use to limit pest population.
Answers
Answer: temperature, animal
Explanation:
Abiotic factor is a non-living environmental factor like soil, water, temperature, humidity, sunlight, and others. Biotic factor is a living factor including living beings like microbes, humans, insects, and others. A limiting factor is the one which can reduce the abundance and growth of living organisms. A limiting factor can be abiotic or biotic.
Temperature is one of the abiotic factors which can reduce the abundance of pests. Increase in temperature can kill pests, which cannot tolerate the rise in temperature. Animal that feed on pests can also reduce the abundance or population of the pests. Like lizards, frogs, and others.
The carrying capacity of an ecosystem will most likely become unbalanced when?
Answers
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.

Answers
Dormant hazard, armed hazard, and active hazard are terms used in risk management to describe different levels of potential danger in a situation. An incident, on the other hand, is an event that occurs as a result of a hazard.
A dormant hazard refers to a situation in which there is a potential for harm, but there is no immediate risk. An example of a dormant hazard could be a gas leak in a closed room.
An armed hazard is a situation where there is a potential for harm, and the conditions are such that a trigger could cause the hazard to become active. For example, a gun with the safety off is an armed hazard.
An active hazard is a situation where harm is imminent and ongoing. An example of an active hazard could be a building on fire.
An incident is an event that occurs as a result of a hazard, such as an explosion caused by the gas leak in the dormant hazard example.

What is your observation in three bean seed experiment?
Answers
The observation which we get from the three bean seed experiment is that for germination to take place, oxygen, water and temperature are necessary in equal proportion.
The purpose of this study is to show that seeds require equal amounts of oxygen, water, and temperature.
A glass slide, a beaker, a thread, and bean seeds make up the apparatus.
Use a glass slide to bind three ripe bean seeds in three distinct places. Place the slide in the water-filled beaker with the top seed above the water, the middle seed at water level, and the third seed submerged in the water.
Observation: Because the top seed receives oxygen but not water, it does not germinate. As it receives both oxygen and water, the center seed begins to sprout. The seeds at the bottom do not germinate, but they do display the appearance of a little radical as a result of a small amount of dissolved oxygen in the water.
Therefore, a seed requires water, oxygen and temperature in equal proportion.

the chances of cancer developing in an individual increases if a cell that has an oncogene also _____.
Answers
The chances of cancer developing in an individual increase if a cell that has an oncogene also loses its tumor suppressor genes or has a mutation in these genes.
The development of cancer in an individual is more likely when a cell containing an oncogene experiences a loss or mutation of its tumor suppressor genes. Oncogenes are genes that have the potential to cause cancer when activated or overexpressed. Tumor suppressor genes, on the other hand, help control and regulate cell growth, preventing the formation of tumors. When a cell with an oncogene loses the function of its tumor suppressor genes, it can result in uncontrolled cell growth and proliferation, ultimately leading to cancer development. Therefore, the simultaneous presence of oncogenes and the loss or mutation of tumor suppressor genes significantly increase the risk of cancer in an individual.

three major differences between human and pig external anatony
Answers
1. Body structure: Humans have a bipedal body structure, meaning they walk on two legs, whereas pigs have a quadrupedal body structure, walking on four legs.
2. Skin covering: Human skin is generally smooth, with body hair spread across various areas. In contrast, pigs have a thicker, coarser skin with bristles, also known as coarse hairs, covering their body.
3. Facial features: Humans have a relatively flat face with a protruding nose, while pigs possess a snout, a long, cylindrical, and mobile structure that they use for smelling and digging.
There are several major differences between human and pig external anatomy. Here are three of them:
1. Body Shape: Humans have an upright posture and a vertical spine, which gives them a distinctive "S" shape. Pigs, on the other hand, have a more horizontal spine and a rounded body shape.
2. Hair/Fur: Humans have a small amount of hair covering their body, while pigs have thick fur that covers their entire body. The hair/fur on a pig's body is also coarser and thicker than human hair.
3. Facial Features: Humans have a relatively flat face with a small nose and two eyes set close together. Pigs have a snout that protrudes from their face, with a larger nose and eyes set farther apart. Pigs also have floppy ears, while humans have small, pointed ears.

a blood cell has a diameter that is 8 cm long. under a microscope, it looks 64000 cm long. what magnification acale was used
Answers
The magnification scale used for a blood cell with a diameter of 8 cm that appears 64,000 cm long under a microscope can be calculated using the formula for magnification.
Magnification = Image size/ Object size
So, Magnification = 64,000 cm/ 8 cm = 8,000.
The magnification scale used for the observation of the blood cell was 8,000. The image of the blood cell appears 8,000 times larger under the microscope than its actual size.Blood cells have a diameter of about 7.5 micrometers, which is equal to 0.00075 cm. Therefore, an 8 cm blood cell would be abnormal and not possible.
The question may have a typo in the diameter measurement. Regardless, the magnification scale calculation remains the same, which is equal to 8,000.

What is the difference between homozygous and homologous?
Answers
There are two sets of chromosomes in humans. Allele pairings are categorized using the terms homologous and homozygous.
Homologous individuals are those who have two copies of the same allele. While homozygous refers to a particular organism with various alleles.
A homologous chromosomal pair consists of two chromosomes that are comparable in length, location of the genes, and centromeres.
Chromosomes are essential molecules because they hold DNA and the genetic code that determines how all cell activity will be directed.
Additionally, they include genes that control particular traits that can be passed down through the generations. 46 chromosomes, or 23 pairs, make up each human cell.
Non-homologous chromosomes have distinct chromosomal pairs. Different gene types are represented by alleles on non-homologous chromosomes.
Non-homologous chromosomes are made up of alleles from different genes.

In contrast to homozygous organisms, which contain both copies of a given gene with the same allele, homologous refers to a degree of correlation or likeness.
Whenever a gene is present on a maternal chromosome, it will also be present in the same location on the paternal chromosome. This is known as homology. It can exhibit additional vigour known as hybrid vigour. Self breeding results in a blend of several qualities.
In homozygous it exhibits no additional vigor over generations, self breeding generates the same trade. It only produce one type of gamete.
