What evidence must be considered when determining whether or not a trait is an adaptation
Rashid [163]

Answer:

An adaptation can be viewed as a trait that emerged and developed for a certain condition so as to increases the organism changes of survival or fitness.

For a trait to be called adaptive, it must have had a positive influence but not majorly a trait that develops in reaction to a certain selection pressure.

Categorically, a trait is seen as adaptation if it is the aftermath of selection, and adaptive if it is of favourable influence at the existing time.

Sam’s teacher is trying to model the day/night cycle on Earth. One student holds a large yellow ball to represent the Sun. Anoth
Orlov [11]
Hello!

So, day and night are caused because the earth makes a full rotation on its axis once every 24 hours.

That way, have of Earth is facing the sun (it is morning on that side) and the other half isn't (which is why it is nighttime over there).

For example, if it's nighttime in Canada and America, it's morning in Pakistan and India. This is because Pakistan and India are facing the sun whilst Canada and America are not.

A N S W E R:

The balls should be moved so that half the Earth is facing the sun and the other half is not. This would be 24 hours. As for the sun, it is a gas, not a solid, so it doesn't rotate like one. However, that does not mean that it is not rotating to some extent.

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) an
gregori [183]

The question is incomplete, the complete question is;

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2

cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

See explanation

Explanation:

If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.

Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.
