<h2>Blood is forced upward and toward</h2>
Explanation:
- In the cardiovascular cycle, the autonomous withdrawal and unwinding of heart cells are facilitated through the movement of the heart's characteristic conduction framework and by cell-to-cell correspondence by means of the hole intersections in the myocardial cells themselves.
- The natural conduction arrangement of the heart comprises of nodal tissue, whose specific cells have both apprehensive and solid qualities. Nodal tissue is restricted in explicit areas of the heart.
Answer:
Explanation:
Gas exchange occurs at the alveoli in the lungs and takes place by diffusion. The alveoli are surrounded by capillaries so oxygen and carbon dioxide diffuse between the air in the alveoli and the blood in the capillaries.

Answer:
<em>The correct ratio will be C) 9:3:3:1</em>
Explanation:
The results infer that the study is about dihybrid cross. According to Mendel's study, the ration of a dihybrid cross comes out to be 9:3:3:1.
This ration cannot give us the exact number of kernels that will be produced and it will also not be able to tell us the exact number for each type of kernels. But it is nearest to the values.
Moreover, if we divide all the ratio's with the smallest number i.e 24 we see that the values are closer. For example, 242 divided by 24 gives 10.1 which is near to 9.
