What is taxonomy
A. An organisms evolutionary history
B. The classification of plants based on their medical uses
C. The science of classification
D. The subgroup of organisms
Why do allele frequencies give us genetic variation
Answer:
why are The more variation a population has, the better its ability to adapt to changes in its environment through natural selection. If there is more variation, the odds are better that there will be some alleles already present that allow organisms to survive and reproduce effectively under the new conditions
Explanation:
What causes a direct rise in CO2 emissions?
A. burning more fossil fuels
B.population growth
C.increased solar activity
D.shrinking habitats
Answer:
A. burning more fossil fuels
Explanation:
The majority of direct emissions are caused by the use of fossil fuels for energy Indirect emissions are caused by the use of fossil fuels to generate electricity, which is then used by an industrial facility to power industrial buildings and machinery. The majority of direct emissions are generated by the use of fossil fuels for electricity. Indirect emissions are emitted when fossil fuels are burned to generate energy, which is then used to power industrial buildings and machinery by an industrial facility.

what is embryogenesis???
Answer:
Embryogenesis is the development of an animal or plant embryo.
OR
Embryogenesis is the process of development of an embryo from zygote. In embryogenesis, the zygote undergoes repeated cell division through mitosis. The divisions help in the growth of an embryo. Cells undergo differentiation attaining specific shape, size and function. Cell differentiation occurs at specific location resulting in the production of different tissue, organs and organ system.

What type of front would you expect to be associated with flooding? Why?
Answer:a stationary front.
Explanation:
they allow repeated thunderstorms to move across the same area.
Answer:
Stationary front
Explanation
they allow repeated thunderstorms to move across the same area. Usually moving alower than a normal storm, which causes large body of waters in one area.

1. Which of the following may not likely be possible when a tall man marries a short woman ?
A) All the progeny may be tall.
B) All the progeny may be short.
C) Some of their offspring may be short.
D) Some of their offspring may be short.
NOTE: EXPLANATION IS REQUIRED.
Answer:
The gene for having a tall stature is a recessive trait. So the man can have only as genotype "aa". The short woman can have instead as genotype either Aa or AA. in the first case, we have both tall and short children while in the second case only short children.
So the answer is A) All the progeny may be tall.
In eukaryotes transcription takes place in the _________. translation takes place in the ________.
1. cytoplasm/cytoplasm
2. nucleus/cytoplasm
3. nucleus/ribosomes
4. ribosomes/nucleus
Answer:
3
Explanation:
The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.
The regulation of genes is regulated and controlled by two main processes of central dogma called transcription and translation.
Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.
This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.
Thus, the selected option is the correct answer.
Which ocean zone supports more species and numbers of organisms than any other zone?
Answer:
the photic zone or better known as the sunlight zone, since photosynthesis occurs here, more than 90 percent of all marine life live in this sunlight. the sunlight zone goes about 600ft deep

The population of deer in Grand Canyon National Park increased from 4,000 to 65,000 between 1905 and 1920. This increase in deer population was due to a ban on hunting and the low populations of natural predators of the deer.
What changes did the deer in the park most likely experience since 1920?
The deer population likely reached its carrying capacity and ceased growth due to a lack of food.
The deer population likely reached its carrying capacity and ceased growth due to a lack of food.,
The deer population likely reached its carrying capacity but continued to grow due to a lack of predators.
The deer population likely reached its carrying capacity but continued to grow due to a lack of predators.
The deer population likely reached its carrying capacity and ceased growth due to its low reproduction rate.
The deer population likely reached its carrying capacity and ceased growth due to its low reproduction rate.

after decomposition in the carbon cycle, put the following steps in order.
- photosynthesis
- fossil fuels or volcanic eruption
- respiration
The correct answer is after decomposition in the carbon cycle, it is first fossil fuels or vulcanic eruption, respiration, and photosynthesis.
Explanation
The carbon cycle is the way that carbon circulates through the atmosphere, oceans, and the Earth's surface and interior through chemical, physical, geological, and biological processes. This cycle is very important because carbon is present in all elements of the Earth. Decomposition is the stage in which organisms (plants and animals) break down and are absorbed by the soil. After millions of years, the carbon contained in these organic wastes becomes the mineral coal that is exploited in mines and extracted for use as fossil fuels, another part of this compound mixes with the processes of the lithosphere and is expelled. in volcanic eruptions. Also, once absorbed by the soil, it feeds the plants that serve as food for different animals that use it for one of their basic processes such as respiration. Once in the atmosphere, the plants absorb carbon again to make their photosynthesis. Therefore, the correct order of the steps of the carbon cycle is Fossil fuels, respiration, photosynthesis.

Explanation:
Duchenne Muscular Dystrophy (DMD) is a sex-linked trait that causes muscular weakness that gets worse as a person ages. Which is most likely true of Duchenne Muscular Dystrophy? A. DMD can only be inherited by females. B. Females with DMD always have a mother with DMD. C. The gene for DMD is located on the X or Y chromosome. D. The gene for DMD is most active in the cells of the reproductive organs.
Answer: C
Explanation:
DMD is s*x linked trait. This means that we have to consider the chromosomes XX and XY. For a male to have DMD, this means the mom must must pass down the allele for DMD. The mom can either be a carrier OR she has to have DMD and the dad can only pass down the Y chromosome. For a daughter to get DMD, this means the dad has to have the allele for DMD and so does the mom. That means that the dad has DMD and the mom can either have DMD or be a carrier. Based off of this logic, we know that the answer isn't B. Because they tell us DMD is s*x-linked trait, it means that the gene for DMD is on the x or y chromosome.
