How the circulatory system works with the digestive system to maintain homeostasis?
Murljashka [212]
Hello friend!!

<span>Homeostasis is the process that helps control/maintain the body. The Circulatory System is one of the systems that is in the Homeostasis process. The Circulatory system is the system that is responsible for transporting blood throughout the body.
</span>
<span>The Circulatory System transports blood all over the body. The blood flows through the arteries. An artery is a small red tube that is connected to the heart and goes throughout the body. The Circulatory System is divided into 3 major parts the Heart, the Blood, and the Blood Vessels. 
</span>
<span>The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood in the Circulatory System is needed throughout the body so that other systems work properly. Like for instance the Nervous System has the brain, and the brain needs blood to function.
</span>
<span>The organs in the digestive system need the circulatory system to continue to digest food.It needs the blood that the circulatory 
distributes for it's nutrients,as well as to have the nutrients spread,so that the body functions evenly.

Hope It helps!!

In chickens, the allele for feathered legs (F) is dominant over the allele for bare legs (f). In a population of chickens on a f
exis [7]

Answer:

0.5

Explanation:

According to Hardy-Weinberg equilibrium p2+2pq+q2=1 (p+q=1)

p2 is frequency of the dominant homozygous genotype

2pq is the frequency of the heterozygous genotype

q2 is the frequency of the recessive homozygous genotype

In the example above 80 chickens have bare legs (ff)-recessive homozygous which means that the frequency of that genotype is 80/240+80=0.25 (q2), frequency of the recessive allele is\sqrt{0.25}=0.5. This means that the frequency of the dominant allele (p) is 1-0.5=0.5

So, the frequency of the heterozygous genotype (2pq) is 2*0.5*0.5=0.5

The frequency of the dominant homozygous genotype is p2=0.25
