Which statement best describes the difference between atria and ventricles? a. atria push blood from the veins to the ventricles, and ventricles push blood from the atria to the arteries.
b. atria push blood from the ventricles to the arteries, and ventricles push blood from the veins to the atria.
c. atria are on the bottom of the heart, and ventricles are on the upper part of the heart.
d. atria receive oxygenated blood, and ventricles receive deoxygenated blood.

The significant difference between the atria and ventricle is that atria push blood from the veins to the ventricles, and ventricles push blood from the atria to the arteries.

Further Explanation:

All the major vessels like arteries, arterioles, veins, and venules have a similar basic structure. They consist of four layers of tissue.

1. The innermost layer is the endothelium.

2. The layer next to the endothelium is elastic fibers.

3. A layer of smooth muscles (much thicker in arteries than in veins).

4. A layer of connective tissue.

The arteries carry oxygenated blood, but the pulmonary arteries carry deoxygenated blood towards the lungs. The oxygenated blood is also carried by pulmonary veins from the lungs to different parts of the body. The arteries are the blood vessels of the circulatory system that carry oxygenated blood to different tissues. The lymphatic system does not have a network of arteries, instead they have lymph vessels. .The atria push blood from veins to ventricles and it pushes blood to the arteries.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
