postnew [5]

Answer:

C4 plant are capable to deal with photorespiration

Explanation:

C4 are more efficient than the C3 plants because the C4 have a mechanism to deal with the photorespiration. C4 combat photorespiration by fixing the intial carbon dioxide between mesophyll and bundle-sheath cells (in space)and calcin cycle. The light dependent process and the calvin cycle are separate in C4 plants. Also C4 plants can adapt easily to even hot sunny environment

Describe the conditions needed in order for any enzyme to function properly.
svetoff [14.1K]
Two main factors that must be taken in consideration are temperature and the pH level.
The temperature shouldn’t be too low as it slows down the rate of reaction, meaning that the enzyme will work slower, but also not too high as it will cause the enzyme to denature (stops working as it should).
The pH level is pretty much the same, shouldn’t be not too low nor too high.

In which type of front is the flow of air on both sides of the front almost parallel to the line of the front?
lisabon 2012 [21]

Answer: the answer is B which is stationary

Explanation:

This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.

Explanation:

The steps to be followed for the PCR procedure are:

<em>Denaturation</em>

Option 1.  Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links

<em>Annealing</em>

Option 3.  Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.

<em>Elongation</em>

Option 2.  Incubate at 72°C to promote the extension of the DNA strands, actually extending them.
