What does the Nucleus, cell membrane, and cytoplasm do?

Biology
1 answer:
Serga [27]3 years ago
5 0

Answer:

The cell membrane holds the cell's internal contents from its environment.

The cell membrane is comprised of two layers of fat.

The cytoplasm is a liquid in which the various organelles of the cell are suspended.

The cytoplasm keeps organelles in place. It also allows different materials to flow from one organelle to another.

The nucleus of a cell contains genetic material. DNA, RNA and mitochondria replicate in the nucleus. The nucleus also produces and replicates proteins, and sends the proteins to other parts of the cell.

Relaxin

<span>Relaxin, secreted by the corpus luteum of the ovary as well as the placenta, is responsible for helping to inhibit uterine activity and to soften the cervix and the collagen in joints. Softening of the cervix allows for dilatation at birth; softening of collagen allows for laxness in the lower spine and so helps enlarge the birth canal. The effect of estrogen is to cause breast and uterine enlargement. Progesterone has a major role in maintaining the endometrium, inhibiting uterine contractility, and aiding in the development of the breasts for lactation. Human placental lactogen (hPL), also known as human chorionic somatomammotropin, serves as an antagonist to insulin, making insulin less effective, thereby allowing more glucose to become available for fetal growth.</span>

What is the conclusion of careful studies regarding the relationship between environmental policies, on the one hand, and jobs a
Karo-lina-s [1.5K]

Answer:

There is a positive relationship between environmental policies and jobs and the economy.

Explanation:

The conclusion of the studies is that environmental policies increase employment in the industrial sector. It is because for reducing pollution, the industries does not use heavy machinery for increasing production so these industries uses labour to maintain its production capacity and for more production more labour is required which decrease the problem of unemployment while economy also increases due to more production of products in the industries.

The gravitational potential energy of Sara at the given height is 10594.8J.

Given the data in the question;

  • Mass of Sara; m; = 60kg
  • Distance from ground; h = 18m
  • Acceleration due to gravity; g = 9.81m/s^2
  • Gravitational potential energy; U = \ ?

<h3>Gravitational Potential Energy</h3>

Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.

It is expressed as;

U = mgh

Where m is mass, h is height and g is acceleration due to gravity.

To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.
