indicate the hypothetical evolutionary relationship between two species of their DNA sequences share a 98 percent similarity

Biology

givi [52]3 years ago

This means that we are virtually certain to share a common ancestor at some point in our evolutionary history. Although this 2 percent difference can manifest itself as huge phenotypical differences between species (such as between humans and chimpanzees), it indicates that our species diverged relatively recently on the evolutionary timeline.

which the following describes a recognition process most closely analogous to adaptive, as opposed to innate , immune recognitio
12345 [234]

Your body recognizes bacteria, viruses, and other substances that seem strange and hazardous and protects itself against them using the immune response.

Which of the following distinguishes between innate and adaptive immunity?

The first line of defense the body has against infections is innate immunity. It does not distinguish between different pathogen kinds since it is generic and non-specific. One sort of immunity that develops as we are exposed to illnesses or receive vaccinations is adaptive immunity.

What else do you call an adaptive immune response?

The adaptive immune system, often referred to as the acquired immune system, is a division of the immune system that is made up of systemic, specialized cells and mechanisms that either destroy infections or stop their proliferation.

Compared with pure cultures grown in the lab, microbes in nature usually experience a wider range of environmental conditions, m
Lorico [155]

Answer:

The correct answer is B-typically grow slower than in pure culture

Explanation:

In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.

In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.  

So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.

Plant height in pea plants is dominant (T). In a wild crop of 8,216 plants, 3,122 are short (tt). How many plants are homozygous
marshall27 [118]

Dominant allele for height T

Recessive allele t

Genotypes for tall Tt or TT

Genotype for short tt.

If there is 8,216 plants, 3,122 are short, which means that 5094 are tall.

Frequency of the recessive homozygous is q2 and it is 3122/8216=0.38, which means that only q=0.62

If p+q=1 (HW equilibrium), than p=0.38

Frequency of dominant homozygous is p2=0.14

The number of dominant homozygous is 0.14*8216=1183

The number of heterozygous is 5094-1183=3911

The number of recessive homozygous is 3122
