The correct answer is A
Explanation:
Cancer including cancerous mass or tumors is caused by an abnormal and uncontrolled reproduction of cells. This means cell division occurs faster than normal and leads to damaged or malfunctioning cells. Moreover, in terms of the number of cells vs time, cancer leads to a high number of cells in a short time. This occurs in cell A because different from cells B, C, and D, this has increased the number of cells in a short time, while others have decreased over time or remain constant. According to this, the cell that is a cancerous mass is A.
The answer is; seeds that store energy in sugar
Sugar is the main source of energy for most life. Oils and fats are used to store excess starch energy for later. Therefore seeds that store oil has to re-convert the oils to carbohydrates so as to respire, However, those that store sugars would just retrieve them from storage and directly use them in respiration.
The answer is; YES
Temperature is an important factor in germination and respiration rate. Optimal temperature range will enable the enzymes to be active and hydrolyze stored energy sources (such as oils and carbohydrates) for energy. Higher than optimal temperatures may denature the enzyme while low temperatures will deactivate the enzymes.
<span> Some of the important features of a prokaryotic cell is that it contains a plasma membrane, ribosomes, and genetic material (DNA) that is not bound by a membrane. Therefore, prokaryotic cells lack a nuclear membrane. </span>
