<span>Body fat directly influences total body water. The influence of age, gender and fitness is also relative. Women and older persons tend to be lower on total boy water because they have lower fat free masses. Athletes tend to have higher total body water, therefore a younger athletic male would have the highest.</span>
The answers are "water and mineral ions" and "amino acids and sucrose" respectively.
For the xylem, it usually transports water and mineral ions that are absorbed from the root hair cells up to the leaves, where photosynthesis take place. Water is one of the necessary substance for photosynthesis to take place, while different mineral ions can help the plant by for example Magnesium ions can help produce chloroplast.
While phloem transports amino acid and sucrose from the location of production (eg. Leaves by photosynthesis) to the place where it is used or stored. Plant needs these substances to generate energy for activities such as growth by for example cellular respiration. This process is called translocation.
Both of these tubes help transport substances in the plant, in order to keep the plant alive.
Though we say that women have lost a lot of blood during menstruation might the cause of low blood volume, but this is not the case.
Testosterone being the male hormone causes an increase in red blood cells production which is responsible for the difference. Testosterone derivatives can also be used to treat anaemia.
The correct answer is option B. Wind-pollinated plants rely on large quantities of pollen grains.
The plants, which pollinate by wind spend less energy in creating attractive structures to attract pollinators, instead they produce many pollen grains, which are light and easy to carry by winds. the pollens are usually dry.
The angiosperm mostly rely on animal pollinator and they have large colorful flowers, which produce nectar to attract the insects or other animals.
