Polarity of a molecule does not involve the symmetry of the molecule rather it deals on with the presence of net charges and partial charges. It would be due to the partial charges present in the <span>single myosin molecules that causes its polarity. Hope this helps. Have a nice day.</span>
This is to prevent water loss by the trees. Under drought or dry conditions, plants may close their stomata to limit the amount of water that evaporates from their leaves a process called transpiration. In this process water diffuses through the stomata into the atmosphere, in a bid to preserve water plants may close their stomata, especially during very dry climates.
By process of elimination you can find the right answer. We know for a fact that carbon is found in all living organisms. That is why we talk about carbon based life forms. So the first statement cannot be true. You can figure out how many Valence electrons an element has by looking at the group number. The group number of carbon is 4 so the 2nd statement cannot be true. We know that carbon does bond with other elements because it is not a noble gas and therefore must be able to form compounds.
This means the answer must be they can form up to four covalent bonds
Answer:
The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
Explanation:
Answer:
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
