How does a comparison of bone structures of two animal provide evidence of an evolutionary relationship
Answer: Comparative Anatomy
Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.
Explanation: hope it helps
mark me as brainliest ^_^
Over the course of evolution, the bones of the animals undergo a gradual change in shape as well as in size. But still, two closely related animals have an identical overall layout of the bone.
What do you mean by Evolution?Evolution may be defined as a gradual process that involves changes or modifications in the members of the same or different species over a long period of time.
The bones of descent common ancestors reveal the evolutionary relationships among the animals. In relationship involves homologous and analogous structures.
The homologous structure reveals the structural similarity between the animals, while the analogous structures reveal the functional similarity.
Therefore, it is well described above.

what causes blue whales to grow so large
Answer:
Stronger upwelling created the right conditions for baleen whale prey, such as krill and forage fish, to become concentrated in dense patches along coastlines. Whales that fed on these prey resources could forage efficiently and predictably, allowing them to grow larger.

Is this animal a carnivore or an herbivore? How do its teeth help it obtain food?
Answer:
This animal is a herbivore. The front teeth help it tear off vegetation, and the back teeth help it chew the plants.
Explanation:
A herbivore's back teeth are adapted to help it chew its high fiber plant diet. The front teeth, however, help it actually put the food in its mouth. The picture below shows a typical goat skull (herbivore), and as you can see, it is similar to the one in your problem. So, that skull is one from a herbivore.

Explain how the VIH virus uses specific structures to enter the cell
Answer:
When HIV infects a cell, it first attaches to and fuses with the host cell. Then the virus uses the host cell's machinery to convert the viral RNA into DNA and replicate itself. The new copies of HIV then leave the host cell and move on to infect other cells.

The mutual interdependence that characterizes oligopoly arises because.
We can confirm that the mutual interdependence that characterizes oligopoly arises because the output for a given market is being generated by a small group of companies.
What is oligopoly?Oligopoly is when the market for a given product is controlled by only a few of the companies that create said product. This situation can have benefits as well as drawbacks. A benefit would be increased product variation, providing more choices for consumers, while a drawback would be a lack of competition to keep prices low.
Therefore, we can confirm that the mutual interdependence that characterizes oligopoly arises because the output for a given market is being generated by a small group of companies.

Scientists have studied the return of plant life on Mount St. Helens ever since the volcano erupted in
1980. Wildflowers began colonizing the area, followed by shrubs and small trees. Scientists predict
that it will likely take hundreds of years before the area returns to a forest dominated by fir and
hemlock trees. These changes are an example of:
a. humans degrading an ecosystem by removing wildflowers
b. the loss of genetic variation in a plant species
C. the growth of a forest through ecological succession
d. the biological evolution of wildflowers, shrubs, and trees
Answer:
C.
The ecosystem there will definitely go through ecological succession by which the structure of the flora there will evolve over time into forests.
If a cell becomes freely permeable to sodium ions (na ) and is not regulated, what will be the resulting membrane potential?
Since their are more sodium ions outside the cell at test, if a cell becomes freely permeable to sodium ions and is not regulated, the membrane potential will be positive.
What is membrane potential?The membrane potential is the potential difference across a neuronal membrane due to the difference in the concentration gradient of oppositely charged ions.
At rest, the inside of the membrane is negative while outside is positive due to more sodium ions being outside the cell.
Therefore, if a cell becomes freely permeable to sodium ions and is not regulated, the membrane potential will be positive.

Which statement describes one way that roots and leaves interact to transport water through plants?
The flow of oxygen out of the stomata of leaves
stimulates the roots to absorb more water for
photosynthesis.
Wilting leaves send chemical signals to the roots,
causing them to take in water at a faster rate.
The evaporation of water through the stomata of
leaves creates a pull that draws water in through the
roots.
Changes in sugar concentration in the phloem of
leaves causes water to move into the roots by
osmosis.
The statement that describes one way that roots and leaves interact to transport water through plants is: evaporation of water through the stomata of leaves creates a pull that draws water in through the roots.
What is transpiration?Transpiration is the process whereby water is lost from the surface of the leaf into the atmosphere.
A process called transpiration pull facilitates the absorption of water by the root hairs of the plant.
The water then moves via the conducting vessel called xylem to other parts of the plant.
Therefore, the statement that describes one way that roots and leaves interact to transport water through plants is: evaporation of water through the stomata of leaves creates a pull that draws water in through the roots.

All statements are true about the energy and trophic levels. So, the correct option is D. None of the above.
What are trophic levels?Trophic levels are the levels of energy transfer from lower to higher levels.
There are five levels of trophic level.
The lower level contains autotrophs or producers. And the uppermost level contains big animals or tertiary consumers.
The energy level decreases on going to the higher levels because some amount of energy always lapses as entropy.
