What will happen to the mass of the tank the next day when it was warmer?

Answers

Answer:

Three cups of the same size are filled with the same mass of fresh water. One cup is put in a bucket of ice water so the water becomes cold, but does not freeze. One cup is heated so the water becomes hot, but does not boil. One cup is left at room temperature. At the macroscopic level, what someone can see with just their eyes, there appears to be very little difference in the volume of water between the three cups. However, at the molecular level, there is a difference in volume.

What does the theory of evolution tell us about how organisms adapt to their environment over time? (4 points)

a
Natural selection occurs before changes in the environment.

b
A population changes in response to a change in the environment.

c
Environmental changes can be predicted based on changes in a population.

d
Natural selection leads to the survival of the population with the most complex traits.

Answers

Answer:

A population changes in response to a change in the environment

Explanation:

B.

Choices A and C should be able to be eliminated pretty quickly. Natural selection is where organisms ADAPT. In order for them to change THEY need to adapt to something DIFFERENT. The only thing the organism should be adapting to is the environment, therefore there should be a change in it. Choice D simply says that organisms only live in a change in environment when complex traits are in place, which simply isn’t true.

Imagine going back in history when giraffes were much shorter than what they are today. Their ENVIRONMENT had much more tall plants than smaller due to other organisms consuming them which led to the giraffe evolving into the tall animals we know today. Being as tall as they are today, those tall plants aren’t so high for them and allow them to get the nutrients and food they need.
