There are 46 atoms of hydrogen inside the cholesterol.

The formula of cholesterol is C27H46O, meaning that besides hydrogen it contains 27 atoms of carbon and one atom of oxygen.

Cholesterol can be found in large concentrations within the liver, spinal cord, and brain providing the stability of the cell membranes.

Hello. This question is incomplete. The complete question would be:

"Cholesterol is an organic steroid in mammalian cells that controls membrane permeability and fluidity. How many hydrigens are in cholesterol?"

Answer:

Explanation:

Cholesterol contains carbon, hydrogen and oxygen atoms, and its molecular form is C27H46O, which means that cholesterol has 27 carbon atoms and 46 hydrogen atoms. Its structure consists of a region of 4 hydrocarbon rings attached to a hydroxyl group at one end and a hydrocarbon tail at the other. The hydroxyl group is the only hydrophilic part of the molecule, which makes it insoluble in blood as mentioned above.

The structure of cholesterol can be seen in the image below.

Answer: 1. Ways to produce meat more efficiently.

1. Livestock farming

2. Ranching

3. Grazing

2. Ways to make agriculture more sustainable

1. Practicing crop rotations.

2. Planting of cover crops.

3. Elimination and removal of soil tillage.

4. Practicing pest management.

5. Integration of livestocks and crops.

3. Organic Agriculture; this is a system of production that helps sustains the fertility of soils, ecosystems and it's people.

Advantages of organic agriculture

1. Reduction in production costs due to absence of expensive chemicals and fertilizers.

2. Farm workers are healthier.

3. Saves energy.

4. Environment protection.

4. Advantages of relying on perennial crops

1. Perennial crops have better access to groundwater due to their deep roots.

2. They require less irrigation.

3. They are more resistant to drought.

4. They help protect topsoil from erosion, runoff, and lose of nutrients which helps make the land fertile for agricultural purposes.

Explanation: meats can be produced more humanely and sustainably by practicing livestock farming and grazing.

The word organic means natural no chemicals or addictive organic farm produce are usually fertilised using animal waste and dungs.

By practicing crop rotation, the soil becomes more fertile unlike when one crop is planted continuously.

Perennial crops help repair our farmlands, unlike annaul crops. They protect the topsoil.

How does the endocrine system control body processes? WORTH 20 POINTS

Sidana [21]

Answer:

The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.

Explanation:

The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.

Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.

Some examples of bodily functions that are controlled by the endocrine system include:

metabolism

growth and development

sexual function and reproduction

heart rate

blood pressure

appetite

sleeping and waking cycles

body temperature

Endocrine system organs

The endocrine system is made up of a complex network of glands, which are organs that secrete substances.

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

The glands of the endocrine system include:
