Answer:
Natural selection is a nature-made selection, and artificial selection is a man-made selection. The main difference between natural and artificial selection is that natural selection produces a great biological diversity whereas artificial selection produces varieties of organisms such as improved crops and livestock.
Explanation:
Plants and certain microorganisms use photosynthesis to create compounds such as carbohydrates. It's an endothermic (heat-inducing) chemical reaction that converts carbon dioxide to sugars using sunlight. Sugars are used by the cell as an energy source as well as a building block for other molecules. Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
It is true that in the science laboratory setting, scientists often struggle to achieve valid results. A possible solution for this dilemma is to repeat the procedure for several trials.
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. If gene pair contains a dominant allele, the the offspring will show this dominant trait
