NAD and FAD work by loading and unloading _________ and _________ during energy transfers.

Answer:

Hydrogen and electrons

Explanation:

Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.  

For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.

Answer:

The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.

There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.

For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.

Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.

lana [24]

Answer:

Answer is option A (True).

Explanation:

The fingerprint pattern of an individual is unique as no two individuals have the same pattern and it remains unchanged. So fingerprints are considered as one of the main types of physical evidence that can be recovered from a crime scene for identification purposes.

The three types of fingerprint impressions are;

Patent fingerprints or visible fingerprints - They are visible prints that are left on a smooth surface of another object when foreign substances such as blood, ink, or some other liquid present on the skin of a finger come in contact with the surface. These prints are easily identifiable and are visible with the naked eye without any technological enhancements.

Plastic prints - They are visible, three-dimensional prints that are left on soft surfaces such as freshly painted surfaces or materials like wax, gum, clay, soap, etc when a finger comes in contact with that surface resulting in an indentation. These prints are easily observable and no enhancement is required.

Latent prints - They are invisible fingerprint impressions that are left on a surface as a result of the perspiration, moisture or oil found in the ridges of fingers. Since they are not visible to the naked eye, enhancement is required upon their collection.
