The pointed structure is known as rough endoplasmatic reticulum (RER), what's more, we can see that it is covered by dots that represent ribosomes. RER is covered of ribosomes that unite amino acids forming proteins, these proteins enter the RER and there are modified and later sent to the Golgi apparatus for final modifications and packaging.
Among organisms, carbon compounds exist in four major categories: lipids, carbohydrates, proteins and nucleic acids. Carbohydrates are required as sources of energy. Proteins are the major molecules from which organisms are built. Lipids provide energy to produce hormones. Nucleic acids consist of deoxyribonucleic and ribonucleic acids, which play a key role in protein synthesis.
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.
