Innate immunity________.

Biology
1 answer:
labwork [276]3 years ago
4 0

Answer:

The answer is A.

Explanation:

Since only 1 of the options is wrong, i assume you are looking for that one.

Two types of immunity systems, innate immunity and adaptive immunity. Adaptive immunity is formed when it is exposed to a harmful substance, vaccines for example create adaptive immunity.

Innate immunity is present at birth which consists our skin protects us physically, chemical substances in our blood that protect us from bacteria and infections and also our blood cells such as T cells.

Since innate immunity forms one of the first lines of defense in our immune system and is the first to respond to a threat in a few hours down to as little as minutes, it is not slower than adaptive immunity in its response to infections and pathogens.

I hope this answer helps.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96

A spider is very different from a human. list two properties that the two species exhibit despite all of their obvious differenc
mars1129 [50]
The two properties that a human and a spider would exhibit is that both of them are composed of eukaryotic cells and the exhibit sexual reproduction. Eukaryotic cells are cells with membrane bound organelles such as the nucleus which contains the genetic material enclosed by a nuclear membrane. Sexual reproduction is a type of reproduction where livings give rise to new off springs by combining genetic material from two individuals of different sexes.

Do you think you would have some genetic traits similar to your grandparents? Explain your answer.
Reptile [31]

Yes, I think I have some genetic traits which is similar to my grandparents.  

Explanation:

Genes are blue print of our body. The 25% gene of Grandparent is similar to their grandchildren. This gene effects the look.  It may affect the color of hair and color of eyes.

Each gene is responsible for different change of our body. Genes pass from one generation to other so it is passed through grandparents to parents and reaches to us.
