Answer:
C. During meiotic division, the members of the chromosome pairs regroup themselves into the original combinations derived from the individual's mothers and father for separation into haploid gametes.
Explanation:
During meiosis, there is a random segregation of chromosomes. Metaphase-I of meiosis-I includes alignment of homologous pairs of chromosomes at the cell's equator.
During anaphase I, the homologous chromosomes are separated from each other and move towards the opposite poles. This segregation of homologous chromosomes to the opposite poles is a random event and creates unique combinations of maternal and paternal chromosomes at each pole and finally in each gamete.
Answer:
Genes are inherited together on the same chromosome.
Explanation:
An independent array of genes has to have different chromosomes or to be sufficiently far on the same chromosome to allow for crossing. The associated genes are in the same chromosome and have no overlap. Together they are transferred to the daughter cells.

It is advantageous for animals that migrate to store energy in the form of lipids rather than carbohydrates. Energy stored as lipids is released more slowly allowing the animal to go for a longer period of time between feedings.
Answer:
Xylem cells transport water and as water is carried from the roots to all parts of the plant, hence the xylem sap will be unidirectional always.
On the other hand, the function of the phloem cells is to transport food to all parts of the plant. Th food is made in the leaves and <u>has to be transported to all parts of the plant from the leaves.</u> Hence, the phloem sap needs to move in any direction so that the food is provided to each part of the plant.
