Linda owns an orchard of orange trees, and she is worried because she notices that many of her orange trees are unhealthy. They

appear to have very little resistance to attack by a certain fungus that is destroying their leaves. She consults with some biologist friends, and they tell her that her orchard is threatened by low genetic diversity. How could she improve the ability of her orchard to resist disease in the future?

ANTONII [103]2 years ago

Answer:

If there is low genetic diversity, she needs to introduce something into the system to increase the variation. I would suggest breeding the orange trees with other new orange trees to change the allele frequencies, which is called gene flow.

Likely the fungi are attacking them somewhere that they have decreased resistance, and if more alleles were introduced, there would probably be evolution towards a genotype that promotes defense against these fungi.

Who uses mitosis and meiosis
quester [9]
Mitosis and meiosis is based off of cells in biology. Mitosis has to do with cells dividing into two identical cells with the same number of chromosomes. On the other hand, meiosis has to do with the parent cell losing half of their chromosomes and dividing twice in order to make four cells.

Evgesh-ka [11]

Answer:

Deletion and glycosylation.

Explanation:

Proteins is polymers of the alpha amino acids that are directly linked together through the peptide bond. Proteins plays an important role in the metabolic pathways as most enzymes are made of protein.

The same protein can exist in two different size. This might occur due to the deletion of the particular amino acids sequence in one organism and normal in other organisms. The glycosylation of the same protein at different position in the proteins may also leads to the difference in the protein size.

Thus, the correct answer is deletion and glycosylation.

Snake venom contains a mixture of enzymes, which include phospholipase that break down cell membranes, proteinases that destroy
Alik [6]

Answer:

The correct answer is - Venom enzyme inhibitors.

Explanation:

The snake venoms are the complex mixtures of phospholipase A2s, disintegrins, serine proteases, C-lectins, and metalloproteases, and others. The snake venom phospholipase A2s (svPLA2s) enzymes found in most of the families of venomous snakes that cause anticoagulant effects, cardiotoxicity, neurotoxicity, and cytotoxicity, and other effects.

In antivenom, there are Venom enzyme inhibitors other than antibodies that help in neutralizing these enzymes by weakening or inhibiting these toxic actions.
