<u>Answer</u>: Option A

<u>Explanation</u> :

  • A<em> fish ladder</em> is also known as fish steps, fish pass or fishway.
  • It is built around waterfalls, dams and locks.
  • The purpose of building a fish ladder is to<em> facilitate the natural migration of diadromous fishes.</em>
  • A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.
  • Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.

Why is insertion/deletion of three bases less deleterious than insertion/deletion of one or two bases.
Ede4ka [16]

Answer:

Explanation:

Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.

If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.

However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.

Will a wound will take a longer time to heal if an individual is lack of carbohydrate?
mezya [45]

Answer:

Carbohydrates Role in the body:

Glucose is necessary in wound healing for a number of reasons. These include: Providing energy for leucocytes and macrophages (white blood cells). Stimulates fibroblast growth etc

Wound healing implicates several biological and molecular events, such as coagulation, inflammation, migration-proliferation, and remodeling. Here, we provide an overview of the effects of malnutrition and specific nutrients on this process, focusing on the beneficial effects of curcumin. We have summarized that protein loss may negatively affect the whole immune process, while adequate intake of carbohydrates is necessary for fibroblast migration during the proliferative phase.
