4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Explain why that happens.

Answers

Answer 1

Answer:

The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.

Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.

Explanation:

Answer 2

shivering burns fat to help keep one warm

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Answers

Answer:

Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.so by not knowing how to generate energy all these things will therefore not be possible. making it harder for humans to survive.

This question should be answered based on your perception of the importance of energy in our society. As this perception is very personal, I cannot answer it for you, but I will show you how to answer it.

First, you should think about all the types of energy we use on a daily basis and how impactful a lack of them would be.

After that, you should write your answer as follows:

The thin segment of the nephron loop's descending limb ________. The thin segment of the nephron loop's descending limb ________. is easily broken and replaced often aids in the passive movement of water out of the tubule aids in the passive excretion of nitrogenous waste helps to pack a greater number of nephron loops into a smaller space

Answers

Answer:

The correct answer is ''aids in the passive movement of water out of the tubule''

Explanation:

The nephron loop has a descending branch, which goes to the renal medulla, and an ascending branch, which goes back to the cortex. The nephrons of these kidneys can have loops of Henle of different dimensions. The thin segment of the loop has thin epithelial membranes, its cells are highly permeable to water, but not to solutes. The water that exits from the descending portion of the nephron loop into the medullary space is immediately reabsorbed by the peritubular capillaries, causing osmolality to increase in both the tubular fluid and the medullary interstitial fluid. The characteristics of the descending branch differ from one species to another, the normal thing is that in one way or another, the osmotic concentration of the urine that moves through it is balanced with that of the interstitial fluid.

If a parent cell has 3 chromosomes before mitosis,how many chromosomes will each daughter cell have after mitosis and cytokinesis?
A.1.5
B.3
C.6
D.12

Answers

Answer:

B. 3

Explanation:

Mitosis is the process of reproduction of somatic/body cells. This means that the number of chromosomes the original (parent) cell started out with, will remain the same for the daughter cells.

Given that if a parent cell has 3 chromosomes before mitosis, then the 2 daughter cells produced will also have 3 chromosomes after mitosis and cytokinesis.

The picture below shows two bodies of water, a pond and a lake. How will these bodies of water most likely experience ecological succession? A The pond environment will be home to more fish and other organisms due to having more resources than the lake environment has. B The pond environment will soon turn into land, but the lake environment will spread into a larger body of water. C The pond environment will grow more plants at its bottom due to having more access to sunlight than the lake environment has. D The pond environment will soon spread into a lake, but the lake environment will recede until there is very little water left.

Answers

Answer:

The answer should be C. 0000

Succession in a pond and a lake will differ because ponds are usually shallower than lakes.

What is succession?

It is the gradual changes to the community of organisms in an environment until a stable community is achieved.

Succession in water bodies may involve the gradual replacement of water by aquatic plants and then by terrestrial plants.

Ponds are usually shallower than lakes. Thus, ponds will receive more sunlight than lakes and grow more plants than lakes as time goes by.

Light is an important factor for plants to grow in any ecosystem.
