Answer:
a cell
Explanation:
its the most basic unit of life itself and the nervous system is made up of neurons and glial cells
Answer:
<em>Nutrition and Growth.</em>
Explanation:
Nutrition: Nutrition is defined as the ability of living organisms to feed. The reason for feeding is to enable living things live and carry out life processes like growth, respiration and reproduction. While all green plants can manufacture their own food through a process called autotrophic or holophytic nutrition. all mamma can not manufacture their own food but depend on plant directly or indirectly for their food, hence this type of nutrition is called heterotrophic nutrition.
<em>Growth: </em>Growth is defined as an irreversible or permanent increase in size, dry mass or weight of an organism due to addition of living proton plasmic materials. The purpose of growth is to enable organisms to repair or replace damaged or old tissue in the body. The food eaten provides the basis for growth of organisms.
The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. ... A purine base always pairs with a pyrimidine base (guanine (G) pairs with cytosine (C) and adenine (A) pairs with thymine (T) or uracil (U)).
The statement that describes a scientific theory is as follows: Jose explained that all planets orbit around the sun in an elliptical path (option A).
<h3>What is a scientific theory?</h3>
A scientific theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.
A theory can also be described as a statement that sets out the laws and principles of something known or observed, in other words, a hypothesis confirmed by observation, experiment.
According to this question, the fact that all planets orbit around the sun in an elliptical path is a scientific theory because it has been tested and confirmed to be true.
Therefore, the statement that describes a scientific theory is as follows: Jose explained that all planets orbit around the sun in an elliptical path.

Answer:
This can be explained based on structure, and on metabolisms of carbohydrate.
Explanation:
Carbohydrate has a relatively simple structural composition than the either protein or fatty acids. The C, H and Oxygen molecules are of relatively fewer in number and few chains than fats and protein.Thus cells will spend less energy to break bonds(catabolisims) among these molecules during cellular respiration pathways to trap the energy.
In addition glucose the end products of carbohydrate did not need any processing before it enters glycolysis, Kreb's Cycle and oxidative phosphorylation pathways to generate energy for the cells.
Conversely, for protein to be used it has to be first deaminated(removal of amino acid) by the liver before it enters glycolysis,while fats needs to be broken down and undergo beta oxidation with the long chains removed before it can form acetyl CoA. Therefore cells will prefer few steps, less endergonic pathways of glucose than longer more endergonic amino acids and fatty acid pathways.
Furthermore, glucose can be used in cellular respiration to produce energy either aerobically or anaerobically, while fats can only be used anaerobically. Therefore, since cells usually prefer to thrive in aerobic conditions they breakdown glucose easily during this period, and when lack of oxygen occurs they switched to anaerobic, Thus, the versatility of glucose to oxygen concentration makes glucose a better choice. Besides if fats was used anaerobically, ketone bodies build up which may be toxic to the cells.
