Answer:
ventricles (VEN-trih-kuhls): The two chambers at the bottom of the heart are called the ventricles. The heart has a left ventricle and a right ventricle. Their job is to pump the blood to the body and lungs.
Explanation:
Answer:
B. Blood in the left ventricle is deoxygenated.
Explanation:
Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.
- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.
- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.
- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs
Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.
B because i am pretty sure that is the correct answer
Answer:
<em>a) Alleles at one locus can hide or mask the effect of alleles at another locus </em>
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". Epistatic genes might be either recessive or dominant. When the epistatic gene is recessive, the interaction is known as "recessive epistasis". While when the epistatic gene is dominant, the interaction is known as "dominant epistasis"
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
