Biodiversity
Explanation:
Biodiversity or also called biological diversity is the variation among life on Earth. It encompasses all life form on Earth including plants, animal, microbes etc.

Why is glucose needed for cellular respiration to produce ATP?
Answer:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

Explanation:
imagine that ou are stduying a very large population of moths that is isolate d from gene flow.A single gene controls wing color.Half of the moths have white spotted wings (genotype WW or Ww) and half of the moths have plain brown wings (ww).There are no new mutations indivisuals mate randomly, and there is no natural selection on wing color.Explain , why any calculation, wether this population is under a hardy weinberg equilibrium
About the question:
I failed to find the complete question. However, I will explain why this population is considered to be in Hardy-Weinberg equilibrium, and what the destiny of the alleles is.
Answer:
This population is in equilibrium because it accomplishes all the H-W assumptions for a population in equilibrium. Genetic nor allelic frequencies will change generation after generation. Alleles will remain equal.
Explanation:
Available data:
A single gene controls wing colorHalf of the moths have white-spotted wingshalf of the moths have plain brown wingsW allele is dominant and expresses white wingsw allele is recessive and expresses brown wingsIndividuals mate randomlyNo natural selectionWe will know by theory if this population is or is not in equilibrium Hardy-Weinberg if the population is in concordance with the assumptions of the theory. So let us first analyze the Hardy-Weinberg assumptions for a population in equilibrium:
• Random matings: Any individual get crossed with any other individual
• No superposed generations: each individual can leave their gametes in the pool only once.
• No mutations: No mutations originate any new gametes.
• No migration: No incorporation of gametes from other populations.
• Infinite population size: the probabilities of randomly taking an A gamete from the pool are p, and the probability of taking a B gamete is q.
• No natural selection: Each individual has equal surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
So, the exposed population
- is isolated, meaning that there is no gene flow from other populations. No new genes will be introduced.
- has no mutations, so no allele will change to express a new form
- individuals mate randomly
- there is no natural selection acting on this group as an evolutive force that might alter the equilibrium.
Genetic nor allelic frequencies will change generation after generation.
In a Hardy-Weinberg population, where allelic frequencies are p and q (assuming a diallelic gene), genotypic frequencies after one generation of random matings are p², 2pq and q². The allelic frequencies, as well as the genotypic frequencies, remain equal after successive generations. Alleles will remain in the population from many generations.
20. Frigatebirds have webbed feet and spend much
of their life flying over the ocean but never land in
the water. What does this fact suggest about the
evolution of these physical and behavioral traits?
Answer:
Evolution changes the abilities of the Frigate birds.
Explanation:
The Frigate birds have webbed feet because they live in the ocean and unable to fly due to its big weight. Before the evolution, the Frigate birds lives in the ocean due to their large body weight but with the passage of time, evolution occurs that leads to formation of flying ability in the bird so now the bird have the old characteristics of their ancestor as well as new abilities in the physical traits of the Frigate birds due to the evolution.
Genes contain the information needed to make _____ that form our traits.
phases of mitosis in the cell cycle
Answer:
These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.

Viruses change at a very fast rate Can you use this information to explain why vaccines against a specific virus don't last forever ?
Viruses can multiply very quickly, and so they can go through natural selection at a much quicker rate, allowing certain vaccine resistant mutations to take over a population.

In a population of birds, brightly colored males and very dull males survive best. Which type of selection is this, and what is most likely true about the proportion of males of intermediate coloring?
Answer:
Stabilizing selection
Explanation:
Stabilizing selection may be defined as the type of a natural selection where the genetic diversity decreases and the population mean stabilizes on the particular value. It occurs to the individual trait when an extreme of the trait are selected against.
In birds, the bright color males attract more mates for survival but they also attract more predators. Over generation, the highest frequency color is for the intermediate coloring males.
How many dominant alleles does an individual have to inherit to show a dominant phenotype
Answer:
one allele
When a trait is dominant, only one allele is required for the trait to be observed. A dominant allele will mask a recessive allele, if present.

how does the respiratory system deliver oxygen to the circulatory system?
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Explain how hormones recognize their target cells
Answer:
A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.
B.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. They then bring the bike inside to a room temperature environment for several hours to warm up and then check the pressure again. They find that the colder temperature showed a high pressure in the tires and that the pressure decreased after the tires were able to warm up.
C.
The students wanted to test the air pressure in a plastic bottle of soda by comparing two bottles. They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.
D.
The students wanted to test the air presssure in a plastic bottle of soda by comparing two bottles. They put one in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the pressure of the bottle which was in the freezer had remained the same. The pressure of the gas in the bottle on the counter increased, causing it to push on the sides of the bottle making it harder to squeeze.
