The reason that the mail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis
Complete question:
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.
The density of a white dwarf is
Answer:
The density of a white dwarf is 1 x 109 kg/m3.
Explanation:
A typical white dwarf is half as massive as the Sun, yet only slightly bigger than Earth. An Earth-sized white dwarf has a density of 1 x 109 kg/m3. Earth itself has an average density of only 5.4 x 103 kg/m3. That means a white dwarf is 200,000 times as dense.
1 x 10⁹ kg/m³ is the density of white dwarf. It is 200000 times denser than Earth. And it is the second densest object we know after neutron star.

Explanation:
Terrestrial planets are Earth, Mercury, Venus, Earth, Mars planets whereas Jupiter, Saturn, Uranus and Neptune are Jovian planets which is also called gas giants. Terrestrial planets means that the planets have rocky soil which is hard in nature while on the other hand, a gas giant is a big planet that is composed of mainly hydrogen and helium element so we can conclude that terrestrial planets are different from gas giant in their soil composition.
A certain stem cell produces only muscle cells. What kind of stem cell is this?
A. Pluripotent
B. Unipotent
C. Totipotent
D. Multipotent
the answer is (B. Unipotent)
Answer:
B) unipotent

Unipotent stem cells come from multipotent stem cells which can only become a few different cell types. Unipotent stem cells can be programmed to be only a specific cell type. They will only follow that one genetic path, thus the name "uni".
Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?
Answer:
Box 1.
Explanation:
The box 1 have the more mass because there are large number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes.

You are the RN starting your shift on a pediatric unit. You are taking care of a 7-month-old infant who has been alert and behaving in an age-appropriate manner on the previous shift. When you perform your first assessment, his parents tell you that in the last hour, he has become sleepier and did not cry when the lab technician drew blood a few minutes ago. Your response is to
A. encourage the parents to keep the room quiet to allow him to sleep.
B. document it and plan to recheck him in an hour.
C. tell his parents to make him wake up because it is not time for him to go to bed.
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Answer:
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Explanation:
Lethargy in infants can be seen in several ways. one of this is that the child may be sluggish and as if he or she has little or no energy. the child may find it difficult to be awake for feeding. And can lose alertness and pays less attention to sounds and the baby is always drowsy. The registered nurse has to assess this baby immediately because lethargy could happen because the baby may have an infection or probably have low blood sugar. Therefore the last option is the best option for the nurse to take.

Some species form social groups only with members of the same gender. For example, elephants form groups with only females and their offspring. Once the male offspring reach a certain age, they leave the group and become solitary.
Which is a benefit of this type of social group structure?
Females do not have to compete for a mate.
Male offspring can belong to more than one social group.
Adult males can mate with females in several different social groups.
Females are the only ones responsible for taking care of the offspring.
Answer:
Females do not have to compete for a mate.
Explanation:
Due to grouping of animals, females do not have to compete for a mate because each group has its own male. They have a male with which she mate and produce fertile offspring and has a complete family so we can say that the benefit of such type of social group structures is that females do not have to compete for a mate in the population as compared to other animals.
Answer:
A. female's do not have to compete for mates.
Explanation:
When the stimulus voltage is increased, _______. When the stimulus voltage is increased, _______. sodium permeability into the cell decreases sodium permeability into the cell increases to overcome the potassium exiting a greater-than-threshold depolarization results a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.
Answer:
a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.
Explanation:
The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.
When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell. The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV. The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.
Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.
The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.

Which product forms from the reaction between nitrogen (N)
(CI)?
A. NCI
B. NCI
C. N2CI
O D. N2C1
Answer:
None of the above
Explanation:
Because as N has the valence of 3 when it reacts with Cl of 1 as valence they will form NCl3Answer:
The product of the reaction between nitrogen (N) and (CL) is nitrogen trichloride (NCl3)
Explanation:
Although by seeing the question's answer choices, I think it was an error to detect the question (image) by Brainly as 2 of the answers is written the same.
However, when nitrogen gas reacts with chlorine gas, the product is gaseous nitrogen trichloride (NCL3), I guess 1 of your answer must be NCL3.

Explanation:
An object is placed at 0 on a number line. It moves 3 units to the right, then 4 units to the left, and then 6 units to the right. What is the displacement of the object?
Answer:
5
Explanation:
Distance is how far something goes and Displacement is how far it is from 0 or from the starting point. Additionally, displacement is a vector so it has a direction, in this case, left or right. To make this shorter let's just find displacement. So you're at 0 and you go 3 units to the right and so you're at positive 3 on the line. Next, you move 4 units to the left so now you're at -1. Finally, you move 6 units to the right and now you're at postive 5. Now you're +5 units away from 0 and so +5 is your displacement (5 units to the right is also correct)
Answer: +5 units or 5 units to the right (as long as it has a sign or a direction it's correct)
