secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body
Answer:
5' --> 3'
Explanation:
New nucleotides are added to the hydroxide group on the ribose sugar side. That is the 3' side.
Examples of metabolic processes that occur in living organisms are:
- Photosynthesis
- Breaking down of lipids
METABOLISM:
- Metabolism refers to the series of processes that involve the breakdown or build up of molecules to release energy or new products.
- Metabolism can either be catabolic or anabolic depending on how it occurs.
- Anabolism is the build up of large molecules from smaller ones while catabolism is the breakdown of large molecules into smaller ones.
- Example of metabolic processes are photosynthesis, breaking down of lipids.

Random orientation of homologous pairs of chromosomes during meiosis I results in alternative arrangements that contribute to genetic variation in offspring. This is called "independent assortment".
<u>Explanation:</u>
The sets of homologous chromosomes, also recognized as bivalents or tetrads, align along the metaphase plate in a random order in metaphase I of meiosis I. Another way for cells to incorporate genetic variation is by spontaneous orientation. Mendel's independent assortment law stipulates that, independently of one another, the alleles of two or more different genes are sorted into gamets.
In other terms, for one gene, the allele that a gamete receives does not affect the allele that is obtained for another.Genetic recombination (by random segregation) and crossing over during meiosis creates daughter cells each containing different combinations of maternally and paternally coded genes.
