Answer:
A. All possible combinations of alleles in the gametes produced by one parent are written along the top edge of the square
Explanation:
You begin with a square. Then, following the principle of segregation, all possible combinations of alleles in the gametes produced by one parent are written along the top edge of the square. The other parent's alleles are then segregated along the left edge. Next, every possible genotype is written into the boxes within the square, just as they might appear in the F2 generation.
Correct answer is True
Please mark as brainiest
The LEFT VENTRICLE of the heart supplies oxygenated blood to the aorta.
Aorta is the main artery that supplies oxygenated blood from the heart to other organs and tissues (except lungs, lungs are for gas exchange instead) so that they get enough oxygen and nutrients.
Meanwhile, the heart has 4 chambers, left and right atrium, and left and right ventricles. Atrium are for receiving blood from different vessels, and ventricles are for pumping blood out of the heart.
Since only the left ventricle is connected to the aorta, so, the answer should be left ventricle.
