A process that increases genetic diversity during meiosis
Answer:
During the prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Explanation:
Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.
What is meiosis?During the prophase of meiosis I, homozygous chromosomes are next to one another and exchange genetic material.
There could be a heterozygous state for a gene if two distinct alleles are present on the same genetic locus on homologous chromosomes. (For instance, an allele for antigen A on one chromosome and an allele for antigen B on another; both are used to determine the ABO blood group.)
Numerous genes are linearly ordered on chromosomes; as a result, some of them may still be heterozygous. (The same person may be heterozygous for the ABO blood group, iris color, and sickle cell anemia).
Therefore, Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

Sperm cells of a specific species of mice have 16 chromosomes. What is the expected number of chromosomes in an adult mouse of this species?
Answer:
32 chromosomes (16 pair)
Explanation:
Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.
That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes

All living things need energy to survive. The most common source of energy for organisms is glucose molecules, which are used as food. A plant’s food is no exception. Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
from the ground.
from the air.
from the water.
from the sun.
Answer:
the air
Explanation:
Plants get the carbon from the air which are needed to make the glucose molecules during the process of photosynthesis in plants. Thus, the correct option is B.
What is Photosynthesis?Photosynthesis is the process of formation of carbohydrate (sugar) in the green leaves of plants. This process takes place in the presence of light. In this process, the light energy (solar radiation) is trapped in the chlorophyll pigment present in the green leaves of plants, this energy is converted into chemical energy in the form of glucose (carbohydrate) which is used by the plants in various processes.
The reaction includes the reaction between carbon dioxide and water molecules which are present in the air to produce glucose and oxygen gas which are consumed as food and in the process of respiration.
Therefore, the correct option is B.

What are some of the natural factors that affect the loss and gain of wetlands in Louisiana?
.What industry contributes to wetland loss in Louisiana?
"The swamps and marshes of coastal Louisiana are among the Nation's most fragile and valuable wetlands, vital not only to recreational and agricultural interests but also the State's more than $1 billion per year seafood industry.What part of Louisiana is most in danger from land loss?
Dozens of reports show the highest rate of land loss occurred in areas with the heaviest amount of oil and gas extraction and canal dredging, Marshall says. According to some studies, the oil and gas industry is responsible for anywhere between 36 to 60 percent of the loss.
Answer:
Natural factors that can cause the loss and gain of wetlands in Louisiana are hurricanes, drought, salt water moving inland, subsidence, and rise in sea levels.

How is biodiversity regulated in a system?
Answer & Explanation:
Biodiversity is regulated primarily by weather in addition to many other factors. Weather changes can cause droughts or flooding. Weather often pushes main species to migrate and therefore cause new biodiversity, indirectly the migration of one species into a new region could cause that new species to consume the already thriving species already in existence which then could reduce the value of species diversity in that region and throw off the pre-existing ecosystem.

Why is the dysphotic zone around coral reefs shallower than the dysphotic zone in the open ocean?
There is more oxygen in the open ocean.
The sun is brighter over the open ocean.
There is more nitrogen by the coral reefs.
There is more plankton by coral reefs.
Answer: There is more plankton by coral reefs.
Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.

Suppose you mate a black rooster with a white hen. The feathers of all the offspring are “gray,” a color that is intermediate between black and white. Explain the inheritance pattern in these chickens.
Answer:
Incomplete dominance
Explanation:
The inheritance pattern described here is called incomplete dominance (sometimes also referred to as semi-dominance or partial dominance). This occurs when the dominant allele doesn't fully prevent the effects of the recessive allele from being expressed. This results in the trait of the offspring being equivalent to the mix of both alleles. If the rooster's feathers are black and the hen's are white, the chicks' will be grey.

Algae has the most energy.
Explanation:
===================================================================
This is because it starts off at the bottom of the chain/level and is like a plant, which gets its energy from the sun.
Plants usually have the most energy in the trophic level, so in this case, its Algae.
When the organism is passed down the trophic levels, the energy gets cut (I forget the amount, it might be in half), so the Shark has the least among of energy in the trophic levels.
