Answer:

c. Leukocytes (white blood cells)

Explanation:

When they do, so-called daughter cells are generated that have receptors identical to those found on the original lymphocytes. The result is a family of lymphocytes, called a lymphocyte clone.

aerobic respiration results in the production of large amounts of lactic acid. How does this impact the body? What is one real l
neonofarm [45]
It’s actually called anaerobic cellular respiration because you’re not using oxygen. For example, when you sprint you can’t breathe very well, so you’re not inhaling as much oxygen you need to make that energy for you to move. Your muscles will go into lactic acid fermentation, and the result of that is energy (ATP) along with lactate (lactic acid), and you will probably start feeling pain as the lactic acids build up.

Hope that helps!

How a polymer molecule is synthesised by glucose?
Kay [80]

Answer:

As a new covalent connection develops between the two glucose molecules, one loses a <em>H group,</em> the other loses an<em> OH group</em>, and a <u>water molecule is freed</u>.

<h2>Why does glucose form a polymer despite being a stable molecule?</h2>

The formation of glucose polymers (glycogen, starch, cellulose) requires the input of energy from uridine triphosphate (UTP). Any tiny molecules must be converted into bigger molecules, which is compatible with the second rule of thermodynamics. Building proteins from amino acids, nucleic acids from nucleotides, fatty acids and cholesterol from acetyl groups, and so on are examples. Energy is released when bigger molecules are broken down into smaller ones, which is compatible with the second rule of thermodynamics. Thus, glucose may be converted to CO2 and H2O, resulting in the production of ATP. While glucose is a tiny molecule and hence relatively "stable," it can exist at a potential energy level and may be used to build up (needs energy) or broken down (<em>produces</em> energy). All of these biochemical processes require the use of enzymes; otherwise, the activation energy of most reactions would require extremely long periods of time for random energy inputs to push the reactions in either direction, despite the fact that energy considerations favor spontaneous breakdown over synthesis.

When do feedback loops fail to work on an ecosystem?
natulia [17]

Answer:

Feedback loop will fail in an ecosystem if the factors regulating the feedback mechanisms fail to function.

Explanation:

Feedback loop is the phenomena in which output is circled back in a way that it is used as input again i.e the reaction is circled back. Its a continuous process.

There are two types of feedback loops, positive and negative, one functions to reinforce and other functions to balance. Positive feedback loops enhance the outputs while negative lower the output and keeps the balance. the variables that are involved in all these processes effect each others so, by eliminating such variables or factors will cause failure of feedback loops.
