Which conclusion is supported by this evidence? Neither ball has a charge. The balls are both positively charged. One ball is po
MA_775_DIABLO [31]

Answer:

The correct answer is - Neither ball has a charge

Explanation:

If the two balls are hanged near one another without touch or an external charge to any of the balls there would be no charge present. In the given question is it given that two balls hang down without any contact in them.

So there is no possible way to generate charge and remain uncharge in their position till they get any external charge.

The correct answer is - Neither ball has a charge

In a population of 100 individuals, 50 are genotype MM, 40 are MN, and 10 are NN. What are the frequencies of the M and N allele
mrs_skeptik [129]

Answer:

F(M) = 0.7 F(N)=0.3

Explanation:

We need to take into account that individuals NN and MM only N or M aleles respectively while MN gives just half of the allelic contribution for each. With this in mind we have the following probabilities for getting each of the alleles: MM => p(M) = 1.0 and p(N)=0.0

MN => p(M ) = 0.5 and p(N) = 0.5

NN => P(M) = 0.0 and p(N) = 1.0

With this we can calculate the frequencies of the M and N alleles in the population with 100 individuals using the following formulas

For f(M):

f(M)=\frac{1.0 (MM) + 0.5 (MN)}{Total individuals}

f(M)=\frac{1.0(50)+0.5(40)}{100}

f(M) = \frac{50+20}{100}

f(M)=\frac{70}{100}=\frac{7}{10}=0.7

The frequency of the M allele is 0.7

For f(N):

f(N)=\frac{1.0 (NN) + 0.5 (MN)}{Total individuals}

f(N)=\frac{1.0(10)+0.5(40)}{100}

f(N) = \frac{10+20}{100}

f(M)=\frac{30}{100}=\frac{3}{10}=0.3

The frequency of the N allele is 0.3

Increased levels of which of the following stimulates the thirst mechanism driving increased water intake? Increased levels of w
Virty [35]

Answer:

The renin angiotensin aldosterone system.

Explanation:

We would be speaking from time to time that Aldosterone would be in charge of increasing blood volume by increasing water consumption.

Aldosterone, a steroid hormone from the mineralocorticoid family, produced by the external section of the glomerular zone of the adrenal cortex in the adrenal gland, acts to conserve sodium, both secreting potassium and increasing blood pressure, the blood pressure is through the increase in blood volume, therefore through the increase in water consumption
