Answer:

Niacin (Ans. A)

Explanation:

Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.

Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.

These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.

What is the problem with organizing organisms taxonomically purely based on their physical traits
masya89 [10]

Answer:

See the answer below

Explanation:

<em>The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.</em>

Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.

Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.

balandron [24]

Explanation:

What are the three waves of an earthquake? Fastet to Slowest

ANS: An earthquake generates three kinds of waves: surface waves (L waves), which are the slowest and weakest; shear (S) waves, which are transverse waves and carry most of the energy; and pressure (P) waves, which are longitudinal waves and travel the fastest. The speed of P waves is approximately 7.0 km/s, and that of S waves is about 4.0 km/s.

What happens to a population of predators, perhaps a pride of lions, if their prey, say the gazelle population, in their area wa
lys-0071 [83]

Explanation:

1. Since the Lions are the predator and Gazelles are the prey therefore a predator-prey relationship exists between them. The predator-prey relation is also associated with the food chain in an ecosystem. If the number of prey is reduced then there are chances that the number of a predator will also be reduced but

2. The Lion is not just the predator of Gazelle but other animals also like deer therefore they can shift their resource of food from gazelles to another organism.

3.The change of the ecosystem will change the population of the predator as the population are adapted to grow in a particular ecosystem and change of population could reduce the population of a predator.

Describe the pros and cons of the treatments used for each of the sickle cell anemia patients investigated in this activity.
notka56 [123]
Sickle cell anemia is caused by an abnormal hemoglobin in red blood cells. hemoglobin is the red pigment found in red blood cells for carrying oxygen.The abnormality arises from a genetic mutation in the DNA gene that codes for the  beta chain of the protein called globin of which hemoglobin is made of.In the beta chain, the sixth amino acid called glutamine is replaced by another one called valine.<span>This one change in the amino acids cause the hemoglobin protein  to behave abnormally, causing  red blood cells to lose their normal spherical shape and become bent like a sickle, hence the name "sickle cell" anemia</span>
