Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.

Eye color is determined by two alleles B and b. B is for dominant for brown eyes and b is recessive for blue eyes. What is the possible genotype of a person with brown eyes? (more than one possible answer)
a. Bb
b. BB
c. bb
Pls be serious when answering this question.
Answer:
A and B
Explanation:
Because B Brown is dominant It will show up in a Bb instead of b Blue. Brown is dominant over blue.
If ther genotype is BB then Brown is the only color that will show.
So A and B will be the answer.
Various gene variations affect a person's eye color. Most of the genes related to eye color make, transport, or store melanin, a pigment. Eye color is directly influenced by the amount of melanin present in the iris's outermost layers. Thus, option A, B is correct.
What effect of genotype on eyes color?Even while eye color is frequently thought of as a simple Mendelian feature, additional research.
Eye color does not follow the conventional hierarchical patterns of heredity, according to observation. Variations in eye color exhibit both epistasis and partial dominance.
Due to B Brown's dominance, it will manifest as a Bb rather than b Blue. Brown is dominant over blue.
Therefore, If their genotype is BB, then Brown is the only color that will show.

Picture D, where chromosomes coil up, nuclear membrane breaks down, and spindle fiber system forms.
Answer:
The illustration of anaphase stage of mitosis is where the spindle fibers start to pull away from the center of the cell.
MITOSIS:
Mitosis is the process whereby a single cell results in two daughter cells that are genetically identical to one another.
Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase.
Prophase: Condensation of chromatids to more visible X-shaped structure called chromosomes.
Metaphase: Chromosomes line up at the cell's equator
Anaphase: Chromosomes are pulled apart by the spindle fibers that attached to their centromere.
Telophase: Reformation of the nuclear membrane.
According to this question, in the anaphase stage, spindle fibers start to pull away from the center of the cell to separate the chromosomes.

Explanation:
Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

b. basalt, andesite, dacite, rhyolite
c. Volcanoes have a crater at the summit formed around a vent through which lava, steam, ashes, etc. are expelled.
2. Mythology was often used by ancient cultures to explain natural phenomena, including volcanoes. Volcanoes have the power to create and destroy, which would have been awe-inspiring to people in ancient times. By creating stories and legends around volcanoes, ancient cultures were able to explain their behavior and attribute their power to the gods or other supernatural beings, thus giving people a sense of control and understanding.
3. Rift volcanoes are volcanoes that form along the boundaries of tectonic plates, where magma rises up to the surface and creates a linear series of volcanic vents. They are typically located along mid-ocean ridges and are characterized by eruptions of fluid basaltic lava. Cinder cones are small, steep-sided volcanoes that are formed from explosive eruptions of gas-charged magma. They are typically less than 300 meters high and are made up of loose pyroclastic debris.
4. Pyroclastic rocks are rocks that are formed from the consolidation of volcanic fragments that were explosively ejected during an eruption. They are composed of different types of materials such as ash, pumice, and volcanic bombs. Pyroclastic rocks can be deposited in various ways, such as air fall deposits, pyroclastic flows, and lahars.
5. There are three main types of volcanoes: shield volcanoes, stratovolcanoes (or composite volcanoes), and cinder cones. Shield volcanoes have broad, gently sloping sides and are made up of fluid lava flows. Stratovolcanoes are tall, steep-sided volcanoes that are formed from explosive eruptions of viscous lava and pyroclastic debris. Cinder cones are small, steep-sided volcanoes that are formed from explosive eruptions of gas-charged magma.

1) How do meteorologists know one storm from another especially if two are occurring at once?
2) If the current storm starts with an ‘H’ what are the next five storms for this year?
Answer:
Satellites, Radars, Storm Spotters
Explanation:
Satellites: Satellites take pictures of Earth at regular intervals from space, telling us where clouds are located. Meteorologists watch these pictures over time to watch for rapidly growing clouds, a clue to a possible thunderstorm. Satellites also can tell us the temperature of the cloudsRadars: Radars send out electromagnetic waves that can be reflected back by precipitation or other objects in the air. Radars can measure the intensity, size, shape, and movement of rain, hail, or debris in a storm. Radars can also show the wind speed and direction near and inside the storm, which can indicate rotation or shear.Storm spotters: Storm spotters are trained volunteers who observe and report severe weather conditions from the ground. Storm spotters can provide valuable information about the location, structure, and behavior of a storm that may not be visible on radar or satellite. Storm spotters can also confirm if a tornado is on the ground or if there is any damageMeteorologists use these tools and techniques to distinguish one storm from another based on their location, size, shape, intensity, movement, and features. They can also compare different sources of information to verify or correct their analysis of a storm.

Use the concept of natural selection to explain how a population of moths might evolve if only a few members can blend in with their environment.
Answer:
A great example is the peppered moths evolution. Since the Industrial Revolution the birch trees started to turn black from the soot. This casued all the white moths to be eaten from birds. The ones that were left to mate were black moths which favored the black gene. So overtime black moths became more common. They were naturaly selected based on color to survived and pass down their black colored genes.
Explanation:
A population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.
What is natural selection?
Natural selection is the force that selects the organism in the ecosystem that can fit best in the environment. In the case of the peppered moth, the light-colored moth was earlier camouflaged with the light color of the bark, so the dark moths were chosen by the predator. Later, after industrialization, the bark became black from pollution, allowing light moths to be seen and eaten by the predator, demonstrating how natural selection varies depending on environmental conditions.
Hence, the population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.

Genes and Proteins in Hemophilia
Genetic researchers at Bay Medical Company are working to improve treatments for hemophilia. Currently, they are investigating the possibilities of gene therapy, which involves changing a person’s genes so that that person no longer has hemophilia. In order to help Bay Medical Company with their research, read the passage below and then answer the question.
Genes are instructions for proteins. Your traits are determined by the kinds of proteins your body makes. For example, when you get a cut, clotting factor proteins connect to form scabs. People with hemophilia do not have a version of the gene with the right instructions for making clotting factor VIII protein. Without the right instructions, their cells can’t make the proteins needed to form scabs. Healthy people have at least one copy of the gene that provides the right instructions for making all of the clotting factor proteins.
If genetic researchers found a way to change a person’s genes, would they be able to cure hemophilia? Why or why not?
