What is eutrophication ?​

Answers

Answer 1
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients. It has also been defined as "nutrient-induced increase in phytoplankton productivity".
Answer 2

Answer:

excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

Suggest an explanation for the evolution of the pigeon-like ancestor into the flightless dodo.

Answers

Answer:

It's ancestors were pigeon-like birds which flew to the island millions of years ago. There were no predators on the island. Gradually, the birds became much heavier, lost their ability to fly and evolved into the dodo.

Explanation:

A local watershed carries runoff from farms, suburban lawns, and wastewater treatment plants into local rivers, and eventually into a local bay. How could this affect the health of the bay?
A. It could make water hypoxic for organisms.
B. There will be an increase of aquatic plants and fish.
C. It could increase dissolved oxygen for fish.
D. There will be decreased nutrients in the water.

Answers

Answer:

answer should be "making water hypoxic for organisms". reason is because the runoff from these treatment plants are filled with nutrients, which will cause eutrophication. eutrophication is excessive algae sprouts which create more DO but then later becomes all used up when they decompose, making it so other organisms have no oxygen.

The runoff water from farms, suburban lawns, and wastewater treatment plants into local rivers affects the health of the bay by making water more hypoxic for organisms. Thus, the correct option is A.

What is Local bay?

A Local bay may be defined as an area of the sea or other water bodies which are usually smaller than a gulf. It is mostly surrounded by water.

The runoff water from farms, suburban lawns, and wastewater treatment plants contain an enormous amount of nutrients that assist the growth of algae over the surface of water bodies known as eutrophication.

These algae consume all much of the available oxygen of the water body and make the environment hypoxic i.e. oxygen deficient.

Therefore, the correct option for this question is A.

B)

D)

Answers

Energy conversions are common in nature. Much of the energy from the breakdown of the hummingbird body weight is released as heat energy back into the hummingbird's environment.

According to the laws of thermodynamics, energy is neither created nor destroyed but is converted from one form to another. Living things take in food to release energy to carry out their daily activities.

Sometimes, energy is obtained from the breakdown of body fat. In either case, much of this energy is released back into the environment as heat energy.

Answers

Answer:

Homeostatis: maintenance of constant internal environment (optimum temperature or optimum optimum osmotic concentration) that permits all the biochemical reactions and physiological functions to proceed with maximum efficiency.

▪For example, when we exercise, there is heat production in the body and the body temperature rises which gets detected by the nerve sensors present in the body and the temperature control system in the brain is activated. It then activates sweat glands that helps in bringing the body temperature back to normal.

Protecting shoreline communities from tsunamis is a struggle, especially in less developed regions of the world. Explain why your experiment supports this statement.

Answers

Protecting shoreline communities from tsunamis is a struggle, especially in less developed regions of the world because tsunamis are unpredictable. These phenomena have a higher effect on low-income shoreline families.

Tsunamis can be defined as giant ocean waves due to earthquakes and/or volcanic activity that occur under the sea.

Tsunamis may devastate entire shoreline communities because they are unpredictable and they speed along like a jet plane.

Tsunamis mainly affect shoreline low-income families in developing countries because the houses in which these people live in developing countries are rudimentary.

Why are braided streams common in sedimentary rocks before the arrival of plants on land ?

Answers

Answer:

Braided rivers have a multithreaded plan form comprising many confluences and diffluences (Miall, 1977). Braid bars and channels can be classified as a hierarchy depending upon their relative size, and three orders of braiding can be seen in proglacial rivers with constant discharge. First-order braid bars are those largest bars which are separated by major channels. First-order bars are made up of a series of smaller, second-order braid bars, which are separated by smaller channels. Third-order braid bars are contained within second-order bars. Complexity of braid pattern is, however, strongly stage dependent, with rivers losing their braided character during peak flood conditions. Braid bars, mid-channel bars, unit bars, and islands have been described in braided river systems on a range of scales ranging from meters to kilometers. All bars are subject to dissection , remobilization, and migration by the appropriate discharge magnitude and frequency (Miall, 1977, 1983).
