What is the wet-bulb depression?

1 answer:

3 0

The wet bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature. It is measured by a psychrometer . If there is 100% humidity, dry-bulb and wet-bulb temperatures are identical, making the wet-bulb depression equal to zero in such conditions. (In short; the difference between the temperature of a dry bulb and wet bulb.)

goldenfox [79]

Answer:

a. PGA down, RuBP up

Explanation:

RuBP, also known as Ribulose-1,5-bisphosphate is a molecule that assist in he fixation of carbon dioxide in the Calvin Cycle or light independent reaction of photosynthesis.

RuBP is combined with carbon dioxide using the enzyme known as rubisco to form an short-lived intermediate product which divides to form two 3-carbon molecule structure known as 3-phosphoglycerate.

<em>If the concentration of carbon dioxide is suddenly reduced, it thus means that the rate of production of 3-phosphoglycerate will reduce as carbon dioxide becomes a limiting factor. Hence, 3-phosphoglycerate's concentration will reduce while more RuBP will become available as a result.</em>

The correct option is a.

Cancer cells are different because they don't enter the G - 0 phase and they are likely to do which of the following Your answer

Allisa [31]

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

what loop prepares the body for change. This is in contrast to a feedback loop that a. brings a parameter back into the set rang

11Alexandr11 [23.1K]

Answer:

The correct answer is - negative feedback loop.

Explanation:

A negative feedback loop takes place in the biology when the end product of a particular reaction leads to decrease in the reaction. A negative feedback loop makes system to bring the homeostasis.

Negative feedback loops takes place inside the body of an individual to decrease the function of a particular reaction, it prepared the body for the change that occur in the atmosphere such as pH, temperature and other.

Thus, the correct answer is - negative feedback loop.
