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.
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)

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.
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.

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
Explanation:
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".
Rapid growth of cells is observed in tumors. One hypothesis of rapid tumor growth is that the creation of new cells uses old cells only as a scaffold to promote rapid growth similar to how crystal solids form. In this hypothesis, new cellular material is not created from preexisting cells. First a new nucleus of a cell attaches to the preexisting cells followed by the formation of the cytoplasm and lastly a cellular membrane forms around the cytoplasm-nucleus complex. This process can only happen if there is a pre-existing lattice network of cells that can function as a site of nucleation. Group of answer choices This hypothesis is not supported by cell theory because new cells are not created from older, preexisting cells. This hypothesis is not supported by cell theory because cell walls are required to grow new cells
Answer:
This hypothesis is not supported by cell theory because new cells are not created from older, preexisting cells.
Explanation:
This hypothesis does not agree with cell theory because it states that new cells do not need pre-existing cells to be created. Cell theory states that cells are generated from old, pre-existing cells, which go through the process of cell division to create new cells.
We can see the disagreement of this hypothesis with the cell theory in the lines:
" In this hypothesis, new cellular material is not created from preexisting cells."

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.

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.

A population of tree frogs lives in an area that has many types of plants and trees. The skin of most of the frogs is gray, which blends in better with the bark of trees than with the leaves of plants. Some of the frogs have skin that is greener in color, which blends in better with grasses and leaves. Snakes and birds are predators of the frog. Humans have come to the area and are beginning to cut down the trees. Describe the probability of survival for the three frogs of each genetic variation of skin colour if most of the trees are cut down. Use evidence in the paragraph to support your answer.
Answer:
with the normal natural predators their chances of survival are high but when humans step in entire forests can be wiped out which will endanger every species of frog
If most trees are cut down, grey individuals will not survive because they will be more exposed to predation. Green frogs will show a greater survival rate. Directional selection is favoring the green phenotype and its genotype.
What is directional selection?
Directional selection is one of the different types of natural selection.
It increases the proportion of individuals with an extreme phenotypic trait.
It causes a decrease in the number of individuals expressing intermediate phenotype, and the other extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example, there is a natural environmental pressure: predation. Frogs need to camouflage to avoid being seen by birds and snakes.
Most frogs are grey. They camouflage with the bark of treesSome other frogs are green. They camouflage with the grass and leaves.The curve in a graph frequency vs phenotype shows a higher frequency of gray individuals.
When humans cut down the trees, they are applying another pressure to the population.
Since humans remove trees, grey frogs remain without a substrate in which to camouflage. They are now exposed to predation.
Birds and snakes can detect the gray frogs better and prey on them.
The grey phenotype and its genotype are affecting the animals' fitness. Grey frogs do not get to survive. So natural selection does not favor it.
Natural selection tends to benefit the green phenotype, which is now the one that increases the frogs' fitness. Green animals are not seen by predators, so they get to survive.
The curve in a graph frequency vs phenotype now shows a higher frequency of green individuals and a sharp decrease of grey frogs.
If more trees are cut down, grey individuals will not survive. However, green frogs will show a greater survival rate.
Directional selection is favoring the green phenotype and its genotype.
