When calculating the rate of photosynthesis, why was it necessary to subtract the rate of O2 change in the light minus the rate
Nezavi [6.7K]

Answer:

plants process oxygen for respiration as an aerobic organism and also produces it, light can regulate this metabolism, which means that in the presence of light oxygen generation occurs as well as consumption and when there is darkness only consumption will occur Thus, when calculating the amount of oxygen that a plant produces during photosynthesis, it will be necessary to subtract the oxygen it consumes, from which it is deduced that the rate of oxygen consumption will not have variations and will be the same in the day and in the At night, so the change of oxygen in the dark is subtracted with the change of volume of oxygen in the light phase

Human mutations may increase resistance to some infectious diseases. Humans which carry the mutant gene, the "sickle cell allele
lys-0071 [83]

Answer:

1 - Malaria

2- Typhoid fever and Tuberculosis

Explanation:

In case of malaria, the causal microorganism is Plasmodium falciparum, which target red blood cells of host. In humans who have defective sickle cell allele, have abnomral shaped red blood cells. So microorganism does not able to attach to abnormal shaped RBCs thus humans having sickle cell allele are more resistant to death caused by malaria.

In cystic fibrosis, mutation on that gene which encodes a protein known as cystic fibrosis transmembrane conductance regulator (CFTR).

Normally Salmonella typhi (bacteria responsible for typhoid fever) enters into intestinal cells by attaching with CFTR receptor. Carriers of cystic fibrosis mutant gene, have abnormal CFTR thus reduced rate of entry of bacteria into carriers.

Normally Mycobacterium tuberculosis (bacteria responsible for tuberculosis) adds sulfate in its cell walls. In carriers of cystic fibrosis, arylsulfatase B activity is reduced which incorporates sulfate. Thus reduced arylsulfatase activity makes bacteria unable to add sulfate in its cell walls thus decreases their virulence to carriers of cystic fibrosis.
