Answer:
The answer to your question is letter B. Photosynthesis
Explanation:
Photosynthesis is a chemical process by which plants and other microorganisms use energy from the sun to produce glucose, water and carbon dioxide. After that, glucose is converted into Pyruvate which goes into Glycolysis and the Krebs cycle.
This description mentions that from simple molecules organisms can to form more complex structures.
Answer:
See the answer below
Explanation:
<em>Jimmy was right to say organisms grow because their cells grow.</em>
<u>The growth of organisms can happen in terms of an increase in the number of cells they have (through mitotic cell division) or an increase in the volume of the cells with or without an increase in the number of cells. </u>
A good example is found in plants, most of which undergo an increase in size without any increase in the number of cells in their bodies. The uptake and storage of water in the vacuole produces a pressure that pushes on the cell walls, causing an increase in length, girths, and other growth features of the cells of plants.
Answer:
ovum
Explanation:
The ovum is produced from oogonia or ovum 'mother cells' through a process called oogenesis in the ovary. The ovum is not only among the largest cells of the body, it is also specialized to ensure accurate fertilization by exactly one sperm cell.
Answer:
The correct answer is: S phase.
Explanation:
DNA can be divided into two functional forms: heterochromatin and euchromatin. Heterochromatin refers to the DNA that doesn't code for proteins or RNA, and thus it remains heavily condensed, for there would be no use to use it for transcription or translation. Euchromatin, on the other hand. is the DNA with the genes that can be transcripted into RNA and translated into proteins; for this reason, Euchromatin is less compact than Heterochromatin.
<u>The only point in the cell cycle where Heterochromatin would be decondensed is </u><u>S phase</u><u> because, in this part of the cell cycle, the </u><u>DNA gets replicated</u><u> in order to prepare for Mitosis</u>. For DNA to be replicated, it first needs to be decondensed to their two strands can be separated and used as guides for the synthesis of the two new strands.
