Which makes viral infections difficult to defend?

Biology
1 answer:
vlabodo [156]3 years ago
6 0

<u>Answer: </u>

Viral infections are difficult to defend as viruses are attacked by a nonspecific immune response.

<u>Explanation: </u>

  • Viral infections often tend to weaken the immune system of the body by turning it incapable of fighting the virus.
  • Any external drug administered to fight the virus also leaves an impact on the beneficial cells causing them to cause side effects.
  • The response of the immune system to the virus often fails to address the root of the virus and hence, the virus keeps growing stronger.

Hierarchy provides an institutionalized although indirect, channel for face-saving resolution of conflict. Group of answer choic
atroni [7]

Answer:

True, the animal Hierarchy a channel for face-saving resolution of conflict.

Explanation:

Face-saving is an action designed not to cause embarrassment to a person while holding a negotiation or a conversation (Folger, Poole & Stutman, 2008). In conflict and its resolution, face-saving is always geared towards preserving dignity, self-respect, personality, or good reputation of the people involved in the conflict, and negotiation. Face-saving, being one of the strategies involved in conflict negotiation, has seen scholars advancing several theories to explain this concept.

The animals hierarchy for vertebrates start from fishes - amphibians - reptiles - birds and mammals (most dominant ).

Q:- In dogs, the Mexican hairless phenotype never breeds true. When Mexican hairless are interbred the offspring are 2/3 hairles
drek231 [11]

Explanation:

The problem says that the hairless phenotype never breeds true. That means that it's not the result of a homozygous genotype (H₁H₁ or H₂H₂), so it is caused by the heterozygous genotype (H₁H₂).

The <u>expected </u>offspring from the cross between two Mexican hairless would be:

<h3>P                 H₁H₂  x  H₁H₂</h3><h3>F1    1/4 H₁H₁,  2/4 H₁H₂ and 1/4 H₂H₂.</h3>

And the <u>expected</u> phenotypic ratio 3:1. However, the observed offspring shows a 2:1 ratio. What's happening?

If the observed phenotypic ratio in the offspring of a monohybrid cross (a single gene with two alleles) is 2:1, we can suspect that one of the genotypes is lethal in homozygosis and therefore does not appear in the progeny (the puppies are born dead).

If we proposed that the H₂ allele is lethal in homozygosis, then:

  • The H₁H₁ genotype would cause normal puppies --> 1
  • The H₁H₂ genotype would cause hairless puppies --> 2
  • The H₂H₂ is lethal and causes the death of puppies --> 0

The phenotypic ratios change to 2:1, as observed in the experiment.
