Answer:
218.75 grams of protein.
Explanation:
If 2500 protein is consumed and its 35% energy is provided by protein then:
2500÷35×100 =875 kcal would be provided by protein.
As one gram of protein provide 4 kcal of energy:
875÷4 = 218.75 grams of potein would be consumed.
<em>Remeber the calories and kcal for food is same.</em>
Answer:
C. Mutation.
Explanation:
The mutation is the source of all genetic variation. There are two types of mutations. One is the natural mutation, and another is the artificial mutation. The natural mutation occurs due to the environmental cause, and humans using various mutagens do artificial mutations.
These two types of mutations always bring variation in any organism. This variation can be positive or can be negative too. Natural mutation is not possible to control so that anything can happen. Either positive or negative changes can occur. But in the case of artificial mutation, in 90% cases, positive results come in genetic variation.

True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.
Answer:
False
Explanation:
Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.
The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.
The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.
The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.
