The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.
The functions that take place within the eukaryotic cytoplasm are diverse:
- Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm. The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.
- Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.
- Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.
On the other hand, in plant cells, the cell wall is located outside the cell membrane.

The answer is, cellular respiration. I hope I helped!
It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.
A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.
Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.
Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the
phase,</em> - <em>the
phase,</em> - <em>the S phase; and</em>
- <em>the
phase</em>.
The phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of phase.
