Answer:
The adaptation makes the orchids more desirable to bees, and therefore more likely to be able to reproduce than other plants without the adaptation.
Explanation:
Answer:
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Explanation:
Genetic variations are important because a diverse gene pool is good for long-term survival of a species since the environment is always changing, so the diversity of DNA offers the most fit of the species a better chance of surviving because they are most adapted to the constantly changing environment.
Some students feel distressed only in test situations. They might be said to suffer from Acute Stress.
Answer: Option B
<u>Explanation:</u>
Stress is your body's reaction to specific circumstances. It's abstract, so something that is distressing for you may not be unpleasant for another person.

Acute stress is the most widely recognized sort of pressure. It's your body's prompt response to another test, occasion, or request, and it triggers your battle or flight reaction.
Explanation:
The size of crystals in igneous rocks can tell us about the physical environment under which the rock formed.
Igneous rocks are rocks that are derived from molten magma formed within the crust.
- When large crystals are formed, it suggests that the magma has cooled slowly without any disturbance. Slow cooling of magma makes minerals to surround nucleation centers easily an take their time to form.
- When small crystals are formed, we can infer that cooling was rapid. Magma had to cool rapidly and several nucleation centers resulted.
- Large crystals in rocks are usually produced deep beneath the earth crust forming a rock type known as plutonic igneous rocks.
- Those with small crystals that forms on the surface are called extrusive or volcanic igneous rocks.
