Answer:
The Earth might seem like it has abundant water, but in fact less than 1 percent is available for human use. The rest is either salt water found in oceans, fresh water frozen in the polar ice caps, or too inaccessible for practical usage. While population and demand on freshwater resources are increasing, supply will always remain constant. And although it's true that the water cycle continuously returns water to Earth, it is not always returned to the same place, or in the same quantity and quality.

Tree squirrels can have different fur colors.
Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch.
[IMAGE ONE]
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.
The diagram below shows how the population changed after many generations.
[IMAGE TWO]
How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.
Answer:
The gray squirrels were easy to see and catch so they died quickly and the population dwindled. The brown squirrels were probably almost the same color as the tree so they were harder to see and catch. The remaining gray squirrels ended up having no other options than to mate with brown squirrels, which probably made appear black squirrels and since the black squirrels population raised, means they are harder to see and be caught by foxes.
How the trees became more black too? I have no idea, sorry.
Explanation:
squirrels: brown, gray

What is Anabolic hormone ?Anabolic hormone has the one that has been involved in the formation of some specific substance just inside the body. Thus it can include repair of the damaged tissues as well as the growth of the muscles as well. There are the examples of the anabolic hormones which are insulin, growth hormones, testosterone, etc.
Insulin has been considered as the sugar regulatory hormone which is made up of the polypeptide chains. It has been called an anabolic hormone because it will promotes the uptake of the glucose by the cells in order to reduce the blood glucose levels. This promotes the formation of the glucagon which is a stored form of energy that can be result in increase muscle mass.
Therefore, The genotype of a true breeding tall plant in mendel's cross is TT. Thus, option B is correct.

Temperature, cloud cover, and thunder are all examples of
O a. storms
O b. weather
O c. climate
O d. barometric pressure
Temperature, cloud cover, and thunder are all the examples of weather. Thus, the correct option is B.
What are the weather conditions?Weather is the state of the atmosphere. This is the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy at a geographical location. On the Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere of the Earth.
Weather refers to the day-to-day temperature, precipitation, and other atmospheric conditions, whereas the climate is the term for the averaging of atmospheric conditions over longer time periods.
Weather includes the sunshine, rain, cloud cover, winds, hail, snow, freezing rain, flooding, ice storms, thunderstorms, steady rains from a cold front or warm front, excessive heat, and heat waves.
Therefore, the correct option is B.
