Answer:Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.For example, tree frogs are sometimes eaten by snakes and birds. Gray Tree frogs blend well in dark wooded areas on tree bark and Green Tree frogs blend in well with green vegetation found in marshes and swamps. A Green Tree frog on the bark of a tree is easier for a predator to find, compared to a Green Tree frog on a green leaf. So, Green Tree frogs that go into habitats where they are not camouflaged are more likely to be eaten by predators. Since Tree frogs that have been eaten do not live to have any more baby Tree frogs, natural selection has favored Tree frogs that live in habitats in which they are more camouflaged.
Answer:
In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
As Earth rotates, coastline B moves to where coastline A is. Which statement is correct about coastline B in its new position?
It will experience a high tide because water is drawn away from the area between the low tides.
It will experience a low tide because water is drawn away from the area between the high tides.
It will have a low tide because the greatest gravitational pull of the moon is experienced when the coastline is at right angles to the moon.
It will have a high tide because the greatest gravitational pull of the moon is experienced when the coastline is aligned with the sun and moon.
Answer:
It will experience a low tide because water is drawn away from the area between the high tides.
Explanation:
The oceans on earth bulge outwards towards the sun and moon due to gravitational pull. This building is highest when the moon and sun are in line (same plane). The coastline within this plane will experience high tides while those at the right angle will have the lowest tides.
meteorites are composed of the original material from which earth was formed. Their compositions range from metallic meteorites made of iron and nickel to stony meteorites composed of dense rock like peridotite
2)Food choices come from what?
Answer:
1) Hunger, savor, appetite. Three main biological reasons why we eat. Also, the economic ability to pay for the food. And the fisical capability to go and buy food, to cook.
2) Our physiological needs are the main reason why we choose food. People need energy to survive.
Everyone would like to have the possibility to eat what he wants. But food choices depend on the financial situation, social class, and preferences.
That is why poor people or people who have less money to spend on food, often eat food that can feed more people but it doesn’t have nutritional values. When people have money, they immediately have a wider spectrum of groceries that can choose from.
Explanation:
Savour is equal to enjoying. When people are not hungry they are happier. We choose what to eat depending on the look, taste, smell, texture. As sweets smell good, people consider them the most attractive food. Food is not just the source of nutrition, it is also the source of satisfaction.
B) damming rivers and lakes.
C) increasing the rate at which land based nitrogen is released into the environment.
D) all of the above
Answer:D) all of the above
Explanation:these are all correct because they all affect our environment
Cellular respiration involves the reversal of the products and reactants of photosynthesis: Water and carbon dioxide, the byproducts of cellular respiration, serve as the reactants in photosynthesis. The byproducts of photosynthesis, oxygen and sugar, are the reactants in cellular respiration.
While photosynthesis utilizes carbon dioxide and releases oxygen, cellular respiration uses oxygen and creates carbon dioxide.We and the majority of other species use the released oxygen for cellular respiration.
The byproducts of cellular respiration include water, ATP, and carbon dioxide. Two carbon dioxide are created as acetyl-CoA is created from pyruvate.
Therefore, During the Krebs cycle, four more carbon dioxide are created. This carbon dioxide is circulated in the blood before being absorbed by the lungs.

The reactants of one are the products to the other, the products of one are the reactants to the other. Opposites. I believe that is the answer.
