Answer:
Answer is hypodermis .
Explanation:
The hypodermis which is also known as the subcutaneous tissue layer, is found lying beneath the dermis and act as a passageway or channel through which blood vessels and nerves passed. It is made up of fat and connective tissues.
It acts as an insulator, this, help in keeping the body temperature stable.
Answer:
here.
Explanation:
Homeostasis is keeping internal body conditions near constant.
Now let's apply this to cleaning our room:
for example, if it's a mess, no one will really tolerate inhabiting it. Same with our body. For our bodies to function, everything needs to be ordered, all the chemical reactions need to happen at a certain rate at a certain time.
Let's for example talk about your room's temperature, if it gets too hot, you're going to switch on the fan and if it gets too cold, you'll hide under a blanket. And you will do this so that you're comfortable enough to carry on with what you do.
Same for our body, if it gets too hot, your body, via negative feedback, will be able to lower it's temperature such that the chemical reactions, keeping you alive, occur at an appropriate rate without enzyme denaturation.
Cleaning up your room from all the dirt is like excreting all the waste products that gives your body a healthy balance. Eg: the carbon dioxide you excrete when you breathe out is important because if it remains in your blood, the blood's ph will drop, which'll affect the rate of chemical reactions. Similarly if the dirt in your room accumulates it's going to smell bad.
Answer:
Option C. Cellular transport that does not require cellular energy, is the correct statement.
Explanation:
Movement of molecules requires energy for transportation from one place to another.
Passive transport is a type of transport in which molecules moves from one place to another without the use of energy. In passive transport, one molecule pulls another molecule and as a result the molecule moves from one region to another.
Answer:
Louis Pasteur demonstrated that cells can only arise from pre-existing cells.
Explanation:
The contributions of Louis Pasteur are one of the most remarkable in the history of humanity. Before Pasteur performed the experiments that revolutionized the cell theory, most people believed in the theory of <u>Spontaneous Generation</u>, which <u>stated living organisms could arise from non-living matter.</u>
However, in the 18th century, <u>Pasteur performed a series of experiments that disproved the theory of Spontaneous Generation</u>. By using using covered and non-covered flasks with broth, he demonstrated that cells were only able to grow in the broth if it was not properly covered, that is, if the air was exposed. This illustrated that cells couldn't arise from non-living matter but the opposite: cells can only arise from pre-existing cells. This was an extremely significant contribution to the cell theory.
