Answer:
Farmers either own or lease land on which they raise crops, such as corn, wheat, tobacco, cotton, vegetables, or fruits; raise animals or poultry; or maintain herds of dairy cattle for the production of milk. Whereas some farmers may combine several of these activities, most specialize in one specific area. They are assisted by farm laborers—either hired workers or members of farm families—who perform various tasks.

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:
q = 1-p-r = 1-0.24-0.6164 = 0.1436
Frequency of individuals with type B blood:
Since pressure is force per unit area, blood pressure could be thought as the force exerted by the blood to the surface area of your blood vessels. When your blood vessels dilate, it means that they expanded. The result would be faster flow of blood. When this happens, the force of the blood is not any more concentrated on your blood vessels because there is more room available.
Think of a faucet where tap water flows. When you stopper the faucet with your finger, you feel the force of the water. The pressure builds up as manifested by the sound your faucet makes. But when you release your finger, the water rushes through and flows faster. The pressure is released. Therefore, when your blood vessels are dilated, your blood pressure decreases.
Euglena are part of the photosynthetic protist group.
The correct option is C.
The hypothalamus is an area of the brain which contain a number of nuclei which have varieties of functions. The hypothalamus link up the nervous system and the endocrine system through the pituitary gland in the brain. The hypothalamus is responsible for the secretion of orexin hormone, which regulates appetite, wakefulness and arousal. Hypothalamus is also responsible for monitoring the secretion of other appetite hormones.<span />
