Answer:
Due to reduced rate of egg production and several disorders caused by hormonal imbalances
Explanation:
Women lose their fertility at the age of 45 while men are able to produce sperm throughout their life. The reasons however for this are not very clear but it has been found that the rate of production of egg decreases with the advancement of age of females. Also the quality of egg degrades thereby reducing the likelihood of an egg being genetically normal. A woman along with faces several disorders due to the hormonal imbalances and one of these disorders is PCOS, ovarian insufficiency etc., which lead to distorted pattern of menstrual cycle.
Answer:
Xylem
Explanation:
Water moves from the roots to the leaves through tissue called the xylem, in a process called transpiration. As water evaporates out of the leaf, more water is 'pulled upwards' to replace what has been lost.
The monomer units of the carbohydrates vary in their total numbers extensively. Moreover, positions of the carbonyl groups along with the orientation of the hydroxyl groups also vary in the carbohydrates' monomers. The presence of any modification is also variable.
On the other hand, the nucleic acids have only 4 monomeric units. The linkages between the nucleic acid residues have less geometry than the glycosidic linkages.
The movement of water molecules in and out of a cell is called osmosis.
Osmosis, or the diffusion of water molecules, is when water molecules flow in or out of a cell from high to low concentrations (down their concentration gradient). The ultimate goal of osmosis is to establish equilibrium between the cell and its outer environment.

I would guess that the answer would be :'<span>These organisms dig more shallow burrows than they used to.</span>' If the crabs actively dig burrows, as many crab species do, and a layer of oil has persisted in the lower soil strata, it makes sense that the crabs would be reducing the depths of their burrows to avoid contact with the oil. The other possibility is that the crabs might might migrate to deeper waters, but this is less likely because the crabs would be evolved to utilise the intertidal zone.
