The cell will enter the G1 phase. During this phase, proteins and nucleotides needed for DNA replication will be produced. Also,

Answer and Explanation:

The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.

During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.

The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.

During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.

G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.

The graph shows the changing levels of hormones during menstruation and ovulation. What is the general trend for hormones after

Vladimir79 [104]

Answer:

Hormone levels generally decrease.

Explanation:

The graph showed that hormone levels after ovulation generally decrease.

The menstrual cycle of women generally have 3 phases which include:

The follicular phase
The ovulatory phase
The luteal phase

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.
