The genes dumpy (dp), clot (cl), and apterous (ap) are linked on chromosome II of Drosophila. In a series of two-point mapping c
Dmitrij [34]

Answer:

The order of genes is- dp-cl-ap

Explanation:

The genes a be mapped on chromosome on the basis of the recombination frequency as the recombination shows that is the genes are linked or not.  In genetic mapping, 1 per cent recombination frequency is considered as 1 cM or map distance.

In the given question, the three gene distance are provided on the basis of which the gene can be mapped in the following manner:

1. Take the higher value of gene distance that is 42 m.u and plot them on the line,

2. now place second-highest value on the line that is 39 m.u.

3. The gene will be arranged in the order of dp-cl-ap.

4. dp--³---cl-----------³⁹---------------------ap.

Thus, dp-cl-ap is correct.

How is the process of carbon fixation in CAM plants different from the process in C3 and C4 plants? a. CAM plants require a larg
Leya [2.2K]

Answer:

The correct answer would be option C.

Plants evolved different methods to prevent or reduce the effects of photorespiration.

The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.

The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.

In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.

The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.

How could the cell membrane then be important for homeostasis
Masteriza [31]

Answer:

The cell membrane is an important factor for homeostasis to happen.

Explanation:

Because the cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
