Active muscles demand huge amounts of oxygen, and the circulatory system works hard to provide it. Blood carries oxygen to the muscles. When the body is at rest, blood carries nutrients to the muscles so that they can repair and rebuild themselves. Blood also carries away the waste products that hard-working muscles produce, back out through the lungs to be filtered.
so they Circulatory system xx muscular system :)
Answer:
The question is incomplete, it lacks the main questions, those questions are:
a. What is the genotype for black chickens?
b. What is the genotype for white chickens?
c. What is the genotype for erminette chickens?
Explanation:
This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.
Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.
The white phenotype will only be expressed when the genotype is WW
The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.
The people of the Canadian Arctic are known as the Inuit. They used to be called Eskimos, which came from a Native American word for 'eater of raw meat'. Now the Arctic people are officially known as the Inuit, which means 'the people', or singularly, Inuk, which means 'the person’ hope this helps!
Different characteristics such as Earth's atmosphere, distance from the Sun, and presence of water make life on Earth possible.
<h3>Is there a groups of rules for organisms to live?</h3>
The idea that there is a group of rules to support life on Earth is controversial but it is clear that life as we know required different features to form.
Some of the most important features that support the emergence of biologically closed systems on Earth include the presence of water in a liquid state, an appropriate atmosphere and a suitable amount of solar radiation.
In conclusion, different characteristics such as Earth's atmosphere, distance from the Sun, and presence of water make life on Earth possible.

Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis.
