The right atrium receives blood returning from others parts of the body through the superior vena cava and the inferior vena cava.  

Explanation:

The pathway of circulation begins in the right atrium which receives the carbon dioxide-rich deoxygenated blood returning through the systemic circulation.  

The deoxygenated blood from regions superior to the heart, i.e., the head, neck, shoulder areas are collected through the superior vena cava and that from the parts inferior or lower to the heart like visceral organs, extremities, trunk, hip etc are brought through the inferior vena cava.

Both these venous systems (superior and inferior) fill the right atrium.

The right atrium then pumps the deoxygenated blood to the right ventricle via the tricuspid valve.

The right atrium is filled with blood during diastole.

Fermentation

Explanation:

Fermentation is the process whereby carbohydrates are converted to acohol or acid by the activities of some enzymes.

Animals of the same general body types have the same anatomy true or false​
horsena [70]

Animals of the same general body types having the same anatomy is True.

Anatomy is the study of the body parts, structures and functions of

organisms.

In situations where animals have the same general body type , then it means

they also have the same anatomy. A good example is mammals which have

the same structure of  body parts and the same anatomy.

Organisms with different body structures however have an entirely different

anatomy which is why True is the most appropriate choice.

Round pea allele R is dominant to wrinkled pea allele r, while yellow pea allele Y is dominant to green pea allele y. Homozygous
allsm [11]

Answer:

RrYy (F1 generation)

Explanation:

This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.

According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.

Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.

In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.

Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
