Verizon [17]

Emerging adulthood is predominantly found in developed countries mainly in western cultures. There most young people completing tertiary education, marrying and becoming parents at a median age of about 30.

Adulthood, the period of human lifespan in which people reach full physical and mental maturity. Adulthood is generally considered to begin when he is 20 or he is 21. From around 40 years old to middle age, around 60 years old to reach the old age.

"Emerging adulthood" is a term that describes the stage of development from about 18 to 29 years old, experienced by most people in their 20s in Westernized cultures and perhaps other parts of the world as well.

Growing adults share five traits: self-focus, instability, identity-seeking, in-between, and a sense of possibility. Emerging adulthood occurs in all ethnic, cultural, and socioeconomic groups, but the experience of emerging adulthood varies among groups.

What can’t males be carriers of sex linked disorders?

evablogger [386]

A carrier does not show disease symptoms, but can pass on the disease-causing allele to offspring. Genes that are located on the sex chromosomes. ... Males cannot be carriers of a sex-linked disorder because they do not have a second X chromosome to make it a carrier.

There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individua

Readme [11.4K]

235 are the Individual numbers that would expect to have the MN type of genotype.

There are two equations necessary according to Hardy-Weinberg Equilibrium:-

p + q = 1

p² + 2pq + q² = 1

Let,

NN= p

NM=2pq

MM=q

So, according to the question, the frequency of genotype NN is 40%

40% of 500 = $\frac{500*40}{100} = 200$ Numbers of individuals

Frequency of individuals p = $\frac{Numbers of individuals}{Total populations}$ = $\frac{200}{400} = 0.4$

Find p² by taking the square root of p.

√(p) = √(0.4)

= 0.632

So, pp + qq = 1

qq = 1 - pp = 1 - 0.63

q = 0.37

The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.

By Multiplying 2 × p ×q to get heterozygous genotype

2pq = 2 × 0.63 × 0.37` = 0.47

2pq = 0.47

So, 2pq × total population = 0.47 × 500 = 235, NM genotype.

Alekssandra [29.7K]

Answer:

The job of both red blood cells and root hair cells is absorption. Red blood cells absorb oxygen through pulmonary veins and their capillaries in the lungs. Root hair cells, on the other hand, absorb water from the soil and transport them to adjoining cells for photosynthesis purposes.

Explain how trees can be produced and yet the smallest trophies level in a pyramid of numbers

antoniya [11.8K]

Oh ok, because producers make up the largest amount of biomass in most food chains, so they put it in the bottom of the pyramid, because the base of the pyramid is the largest part of it.
