Answer:
C.
Explanation:
Every DNA nucleotide pair will consist of one pyrimidine and one purine. Due to the chemical structures of the different bases, adenine (A) will always bind with thymine (T) and guanine (G) will bind with cytosine (C). The same is true for RNA except that A always pairs with a close relative of thymine, uracil (U).
Answer:
Hormone levels generally decrease.
Explanation:
<em>The graph showed that hormone levels after ovulation generally decrease.</em>
The menstrual cycle of women generally have 3 phases which include:
- <em>The follicular phase</em>
- <em>The ovulatory phase</em>
- <em>The luteal phase</em>
The follicular phase is characterized by low levels of oestrogen and progesterone and a slightly high level of follicle stimulating hormone which ensures that follicles within the ovary develop.
The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.
The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.
Answer:
The question to be asked an investigated when observing a structure under the microscope to determine whether it is living is if it has a nucleus if eukaryote or nucleoid if prokaryote.
Explanation:
The major organelle that must be present in all living cells is the nucleus or nucleoid and the protoplasm. The observation of the cell under the microscope will show the subcellular entity, nucleus/nucleoid, more pronounced than other organelles in the cell. The nucleus house the necessary information for the maintenance and reproduction, which is mainly the genetic information that dictates the translational protein products that are needed to build another aspect of the cells. Therefore, when such a tiny structure is placed under the light microscope under the view of oil immersion, the nucleus of the cell should be visible if it is a living structure.
True. it starts off simple then you move into details
