Answer:

The dissolving power of water is very important for the transport of nutrients in blood.

Explanation:

Water is known as the "universal solvent" because it can dissolve more substances than any other liquid. The dissolving power of water means that it can effectively transport nutrients, chemicals, and minerals. Plants rely on water to carry dissolved nutrients from the soil. Animals also benefit from water as a solvent.

Answer:

the frequency of individuals with Type B blood in the population is 0.1977

Explanation:

Given:

Frequency of A allele is p = 0.24

Frequency of the individuals with blood type O is r = 0.38

Question: What is the frequency of individuals with Type B blood in the population, fB = ?

You need to apply the Hardy-Weinberg Equilibrium:

p²+q²+r²+2pq+2pr+2qr = 1

Here,

p, q and r are the frequencies of the alleles

Calculating the frequency of the allele q:

$r=\sqrt{0.38} =0.6164$

q = 1-p-r = 1-0.24-0.6164 = 0.1436

Frequency of individuals with type B blood:

$f_{B} =q^{2} +2qr=(0.1436)^{2} +(2*0.1436*0.6164)=0.1977$

Muscle contraction that results in a change in joint angle is called

Alex_Xolod [135]

Muscle contraction that results in a change in joint angle is called concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.

Candida can invade tissue by producing the exoenzymes __________ and __________.

choli [55]

Answer:

Candida invades tissues by producing the exoenzymes protease and phospholipase.

Explanation:

Candida is a genus of yeast and a member of the fungi kingdom. It is the most common cause of fungal infections like oral thrush, candidiasis, and vaginal yeast infections.

Candida produces the exoenzymes protease and phospholipase, which help in invading and spreading the infection in the host cells.
