Answer: Option E.
Coronary sinus, right atrium.
Explanation:
Coronary sinus, right atrium is part of the circulatory system that consist of arteries, arterioles, veins, capillaries that move blood to the heart tissue and remove waste from the blood.
The cardiac veins return deoxygenated blood to the right atrium and it them moves to the right ventricle then to the heart where it becomes oxygenated
The coronary sinus received drain blood from ventricles veins, it then moves the deoxygenated blood to the right atrium which it transfer or move to the right ventricle (through the tricuspid valve which in turn move the blood to the pulmonary artery for pulmonary veins.
Answer:
1, Planting trees
2. Actions that reduce carbon dioxide emission
Explanation:
Ally can reduce the amount of carbon dioxide in the atmosphere in two ways
1. By planting trees or reforestation
Trees generally act as a sink for carbon through photosynthesis. Hence, planting more trees means that more carbon dioxide in the atmosphere will become fixed into the trees leading to the reduction of the gas in the atmosphere.
2. Reducing emission
To further reduce the amount of carbon dioxide in the atmosphere, the rate of emission of the gas has to be reduced. Actions such as the burning of vegetation and fossil fuels need to be reduced because they increase the emission of carbon dioxide gas into the atmosphere. The actions can be substituted for less or no carbon dioxide emitting alternatives.
<em>When less carbon dioxide is emitted into the atmosphere and more is being fixed into trees, the overall concentration of the gas in the atmosphere will reduce greatly with time.</em>
Answer:
cytoplasm
Explanation:
A cell can be thought of as a "factory," with different departments each performing specialized tasks. A cell's plasma membrane regulates what enters or leaves the cell.
Answer:
Option B, A phosphatase removes the phosphate group from phosphorylated amino acid residues in a protein.
Explanation:
A phosphatase enzyme is responsible for removing phosphate group from a protein.
This usually happens during the chemical process of hydrolysis in which phosphomonoester is hydrolysed using phosphatase as a catalyst..
The final output of this reaction are -
a) Phospahte ion with OH group attached to it
b) H+ ion attaching to the hydroxyl group of the other product.
c) Splitting of water
Option B is correct
50 percent, Tt crossed with a tt will be Tt, Tt, tt, tt, so it will be 50 percent
