Answer:
Alternative splicing
Explanation:
One gene can lead to multiple proteins by the alternative splicing of the mRNA. The alternative splicing is the most common process that contributes to protein diversity at a pot-transcriptional level. This process is carried out by different combinations of including or excluding exons of the mRNA, obtaining proteins that differ in their amino acids sequence, consequently having different biological functions.
Due to the reduction in large industrial emmissions such as fertilizers into water zones.

The sun. Greenhouse gases absorb heat better. So the more of these gases, the hotter it gets. However, the earth itself is naturally heating, but it goes too fast for live to adjust to the temperatures.
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.
