Explanation:
All living organisms need nutrients to survive. While plants can obtain nutrients from their roots and the energy molecules required for cellular function through the process of photosynthesis, animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular function. The conversion of the food consumed to the nutrients required is a multistep process involving digestion and absorption. During digestion, food particles are broken down to smaller components, which are later absorbed by the body. This happens by both physical means, such as chewing, and by chemical means.
One of the challenges in human nutrition is maintaining a balance between food intake, storage, and energy expenditure. Taking in more food energy than is used in activity leads to storage of the excess in the form of fat deposits. The rise in obesity and the resulting diseases like type 2 diabetes makes understanding the role of diet and nutrition in maintaining good health all the more important.

Controlling the level of sugar in the blood is an example of a feedback mechanism
A tendency for the brain's left and right hemispheres to serve different functions is called lateralization. It <span>refers to how some neural functions, or cognitive processes tend to be more dominant in one hemisphere than the other. Hope this answers the question. Have a nice day.</span>
Proteins are important biomolecules. Proteins are synthesized and often packaged for secretion into other cells within an organism. A variety of organelles play a role in producing, packaging, and moving proteins.
Organelles of Eukaryotic Cells
Organelle Function
Nucleus The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.
Mitochondria Make energy out of food
Ribosomes Make protein
Golgi Apparatus Make, process and package proteins
Soil can cause a natural disaster by soil erosion
