We should remember that we should consume all necessary nutrients at a correct amount and proportion. this includes the primary food substance carbohydrates, fat and protein. and protective food substance in a small amount, which includes mineral ions ( iron, calcium etc) and vitamins. Also we have to take in enough water (6-8 cups a day) and fibre to prevent deficient diseases and to maintain health.
in addition, note that the amount of food intake varies with age, sex, body status, daily activity etc. For example, teenagers and pregnant women should increase all necessary nutrients intake to ensure proper growth and development of ourselves or the baby.
The correct answer is the final option - sickle cell disease and malaria are both potentially lethal diseases.
The other options are incorrect because sickle cell disease is an inherited disease, but malaria is not - it is an infectious disease. However, both of these disease are quite dangerous, and may have severe consequences (such as death) if they are not properly treated.
Answer:
As the heart pumps, glucose is carried in the bloodstream to cells all over the animal’s body. Oxygen which enters the animal’s body through its respiratory system (lungs, gills, skin, or exoskeleton) is carried by its transport system (blood for many animals to every animal cell. Once the glucose and oxygen arrive in the cell they can go through a chemical reaction. Glucose reacts with oxygen to produce carbon dioxide and water. Cells transform the chemical energy in the glucose molecules into energy for cell functions, motion energy, and heat. Because of cellular respiration, muscle cells have access to the energy necessary to contract or relax in response to a signal from the brain sent through nerve cells, so muscles can contract or relax enabling the animal to move. During cellular respiration, energy is released in the cell to enable the work of the cell to occur. The atoms found in glucose are rearranged into carbon dioxide and water and are no longer needed by the cell so they are considered waste products. Cells have to get rid of unwanted waste products. Carbon dioxide and water move out of cells and into the blood. The blood carries the carbon dioxide and water to different places in different animals (the lungs, gills, skin, kidneys, or exoskeleton) where they are released into the environment. Animal movement we observe at the macroscopic scale is possible because cellular respiration is happening at the atomic-molecular scale.
The cost-benefit analysis done to investigate a proposed mine site would take into consideration the cost of environmental restoration after mining and the value of the ore to be extracted from the mine.
<h3>Cost-benefit analysis</h3>
This is an analysis done to assess the cost and benefits of actions.
For an action to be profitable, the benefits must be more than the cost.
In this case, for a mine site, the value of the ore to be extracted from the mine has to be more than the cost of having to restore the site after mining.
Every other cost can also come in but the two major ones are those highlighted.

Answer:
Explanation:
The pellets from a barn owl often contain the remains of 4 or 5 small animals. Let's assume an average of 4.5 animals per day.
1. Animals per week
2. Animals per year
3. Animals per month
