Biology

SOVA2 [1]3 years ago

Answer: cause some plant cells to grow longer than others.

Explanation:

Auxins have a large range of physiological effects, but they are typically known for their involvement in cell elongation and its synergistic interaction with cytokinins in the regulation of the cell division process. These two hormones, when applied exogenously, control the organogenesis of roots and branches in plant tissues. The effect is dependent on the ratio of auxins to cytokinins, a high ratio of auxins induces root formation, while a high ratio of cytokinins induces the formation of branches.

In other words, this substance promotes the elongation of cells, and one of the main natural occurring auxins is AUXIN. 3-Indolylacetic acid (AIA). It is synthesized at low levels in all tissues, but mainly meristematic apical stem, young leaves, fruits and developing seeds.

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:

<em>The graph showed that hormone levels after ovulation generally decrease.</em>

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

  1. <em>The follicular phase</em>
  2. <em>The ovulatory phase</em>
  3. <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.

Answers:

1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.

2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.

3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.

Step-by-step explanation:

Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.

Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.

Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
