M phase, or mitosis.
(You don't need to know this for your course but more properly cell division could also refer to meiosis or binary fission.)
In the heart, the valves are located between atria and ventricles and between ventricles and arteries (option D).
<h3>What are valves in the heart?</h3>
Valves are membranous partitions which permit the passage of the contents of a vessel or cavity in one direction, but stop or control the flow in the opposite direction.
Valves in the heart enforce a one-way blood flow through the heart and separate atria from ventricles, and ventricles from the large arteries that leave them.
The four valves in the heart and their location is as follows:
- tricuspid valve: located between the right atrium and the right ventricle
- pulmonary valve: located between the right ventricle and the pulmonary artery
- mitral valve: located between the left atrium and the left ventricle
- aortic valve: located between the left ventricle and the aorta.
The valves between the atria and ventricles are called atrioventricular valves or cuspid valves while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
Therefore, it can be said that the valves of the heart are located between atria and ventricles and between ventricles and arteries.

Answer:
The coastal ocean seems to be more productive than the waters of the similar height in the open ocean due to ample availability of water, sunlight, and nutrients. The coastal ocean has more nutrients due to the process of upwelling, that is, movement of water offshore by the currents.
Also, water situated on the continental shelves is comparatively shallower and thus it is turbulent. This mixing or turbulence keeps settling the nutrients stirred up and accessible, and eventually, ample of nutrients erode off the continents themselves and so water nearby to the shore seems to be greater in nutrients.
On the other hand, in the surface water away from the coastlines, usually, there is a lot of sunlight but no availability of adequate nutrients. Therefore, the majority of the ocean surface is not much productive.
Explanation:
Answer:
cooling of lava or magma makes igneous
sedimentary rock is formed when sediment gets deposited, and is hardened by compaction and cementation.
any rock can turn into a metamorphic rock when exposed to extreme heat and pressure
Yes, because there is only so much weight it can hold.
