<h2>Answer:</h2>

mechanism: the process of evoluton .

Evolution is the process by which veriety of modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all 0rganisms and the amazing diversity of that organisms but exactly how does it work? Fundamental of the process of evolution is genetic variation upon which selective forces can act in order for evolution to occur.

Examines the mechanisms of evolution focusing on:

•Decent : the genetic differences that are heritable and passed on to the next generation successfully.

• mechanisms of change: Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .

• The random nature of genetic drift and their effects .

• How variation, differential reproduction, and heredity result in evolution natural selection .

• How different species can affect each other's evolution through co-evolution.

All of these mechanisms can cause changes in the frequencies of genes produce change in in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

The fundamental resolution of an optical instrument is set by

yaroslaw [1]

Answer:

The wave nature of light is the fundamental resolution of an optimal instrument.

Explanation:

All the optical instruments are working on light that's why they are known as optical instrument. Optics means the behavior of light or sight. Light is an electromagnetic radiation which comes in the category of electromagnetic spectrum. It travels in the form of wavelength.

So, optical instruments are based on wave nature of light.
