Base on the question that asks to choose among the following choices that is significance of the apical meristem, base on the fact, apical meristem is found at the apices or tips of the plant, both the tip of the shoot and the root and is a region of actively dividing cells. Base on that the answer would be "It provide strength to the plant by facilitating secondary growth"
Hydrophilic
A phospholipid is comprised of a phosphate hydrophilic head, which means that it is "water-loving," and a fatty acid hydrophobic tail, which is "water-hating." The head and the tail are joined together by a glycerol molecule.
The phosphate head is attracted to water because it is charged (i.e. negatively). Water is a polar molecule, which means that there is an uneven distribution of charges within its molecular structure with the oxygen side being "more negative" than the rest of the atom (which is "more positive" near the hydrogen). Thus, the negatively-charged nature of the phosphate head and the parts of the water molecule which are positively charged enable the two to form an "attraction" towards one another.
On the other hand, the hydrophobic tail is nonpolar, which means that it does not have a "more positive" or "more negative" side or part in its molecular structure. These differences in structure with water make the hydrophobic tail unattracted to water molecules and more attracted to other uncharged, nonpolar molecules (such as fats and oils).
Please mention the option so it'll be clear to answer then.
Answer:
Stimulation of Islet cells...
Explanation:
These are the cells of pancreas that get stimulated even by a slight abnormal change in blood glucose levels. The insulin is produced if blood glucose get too high and glucagon is produced if its too low. Both of these are crucial hormones for proper management of glucose in blood and work together by feedback mechanism of secretion control.
