Identify which layer of the integumentary system each of the following is most likely to be found and provide a one phrase description of each (3pts): Phagocytic cells Keratinocytes Arrector pili Papillae responsible for fingerprints Melanocytes Paccinian corpuscles
Answer:
The integumentary system comprises the skin, nails, hair and exocrine glands. The average persons skin weighs a approximately 9Kilograms and spans about 20 square feet.
Phagocytic cells: These are found in the dermis or hypodermis. The skin layer that lies directly beneath the epidermis and above the subcutaneous layer is the dermis. It is made up of fibrous and flexible tissue and is the thickest layer of the skin. It thus gives the skin power and flexibility.
Phagocytic cells are cells within the skin that are designed for detecting, engulfing, and destroying pathogens (such as bacteria and other harmful organisms) and apoptotic cells. Apoptotic cells are cells in the human body that have spent their lifespan and are ready for replacement.
Keratinocytes: This is the most common type of cell in the human skin. It is mostly found on the Epidermis and comprises about 95% of the same.
The Epidermis is the most visible part of the skin. It is the part of the skin which the eyes can see. Its function is mostly protective. It receives all nutrition from the dermis because it does not contain any blood vessels.
Arrector Pili Muscle: Beneath the skin, there are tiny muscles that are attached to the base of a hair follicle at one end and to dermal tissue on the other end. These are known as the Arrector Pili.
Papillae: The dermal papillae comprise a little amount of the dermis. They project out of the epidermis. They aren't always immediately visible on the surface of the skin but tend to be quite obvious when examined under a microscope.
Melanocytes: These are neural crest-derived melanin-producing cells. They are mostly found in the lower layer of the skin's epidermis (also known as the stratum basale), the middle layer of the eye (uvea), the inner ear, the vaginal epithelium, the meninges, the bones, and the core. A black pigment mainly responsible for skin color is melanin.
Paccinian corpuscles: can always be seen in the deep part of the dermis of both glabrous and hairy skin. Structurally, they are very much like the Meissner's corpuscles.
Paccinian corpuscles can be found in the Periosteum of the bone, capsules of the joints, pancreas, other internal organs, breast, and genitalia.

which of the following materials are being transported in and out of the cell through its cell membrane
A: dna and mitochondra
b: energy and water
c: waster and nutrients
PLEASE HELP FAST
Answer:
B
Explanation:
Because its the circle of life
Waste and nutrients are the materials are being transported in and out of the cell through its cell membrane. Thus, the correct option is C.
What is membrane transport?Membrane transport is the collection of mechanisms which regulate the passage of solutes such as the ions and small molecules through biological membranes such as plasma membrane, which are lipid bilayers that contain protein units embedded in them.
The regulation of transport passage through the membrane is due to the selective membrane permeability, which is a characteristic of the biological membranes that allows them to separate substances of distinct chemical nature to transport through them. Cell waste and nutrient are two such materials which are being transported in and out of the cell through its cell membrane.
Therefore, the correct option is C.

Why do you think it is advantageous for cells to go through the different
phases of the cell cycle (such as copying their genes or building the
materials needed for division) in an ordered way? What might happen if a
cell underwent all of these activities at once?
Answer:
it is advantageous because all cells will go through the same process and divide correctly, they won't grow out of proportion. If they went through all these activities at once, there would be a higher chance of losing the cell.
Explanation:
If a cell underwent all of these activities at once, there will be a risk of damaging the cell.
What do you mean by a Cell?A cell may be defined as the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
A cell always goes through the different phases of the cell cycle in an ordered way. This is because a cell must have to divide and differentiate properly. But if a cell underwent all of the activities of the cell cycle at once, it is very tough for the cell to perform which activity at first, in this way cell loses its structure, and its identity and is finally damaged.
Therefore, if a cell underwent all of these activities at once, there will be a risk of damaging the cell.

DNA sometimes has chemical groups attached, called methyl groups, that affect gene expression. Suppose that, during each hour, first a fraction m of unmethylated locations on the DNA become methylated, and then a fraction u of methylated locations become unmethylated. Find a recursion for the fraction f of the DNA molecule that is methylated.
Answer:
f = m - u
Explanation:
DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).
In consequence, the equation is
f = m - u

While working in a genetics lab over the summer, you isolated a true-breeding strain of wingless Drosophila. After sharing your results with your mentor, you learn that six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in your lab. Your mentor asks you to determine if the mutants belong to the same complementation group. What is true about flies that belong to the same complementation group?
a. They all have the same mutation in the same wing- development gene. All flies in a complementation group have identical DNA sequences for this gene.
b. They all have some mutation in the same wing-development gene. Each strain may have a different mutation, but the same gene is mutated in all trains in a complementation group.
c. They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Answer:
C: They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Explanation:
From the situation of the question given, we can say that the true statement about flies that belong to different complementation groups is option C primarily because Strains existing in different complementation groups obviously would have mutations in different genes.
The image shows the concentration of a solute on both sides of a semi-permeable membrane. What do you predict concentrations will be at 15 seconds? (Homeostasis Gizmos)
Answer:
According to the image it can be predicted that the concentration of a solute on both sides of a semi-permeable membrane at 15 seconds will be equal on both sides (60/60), since the equilibrium reached at 10 seconds is maintained.
Explanation:
When a solute exists in different concentrations on both sides of a semipermeable membrane, the solute will be pushed from the place of higher concentration to the place of lower concentration, following a concentration gradient. Particle movement in this case will stop when equilibrium has been reached, i.e. when the solute has the same concentration on both sides of the membrane.
What the image shows is a solute that was on both sides of the semipermeable membrane at different concentrations. In the second 10 the concentrations on both sides were already equal, equilibrium had been reached and the concentration gradient disappears. At 15 seconds the concentrations should remain the same, since equilibrium has been maintained.
The semi-permeable membrane is a type of membrane which allows only to pass solute molecules. The flow of water from a high concentration to a low concentration is called osmosis.
According to the image, we can predict that the concentration of a solute on both sides of a semi-permeable membrane at 15 seconds will be equal on both sides (60/60) since the equilibrium reached at 10 seconds is maintained.
This condition is stated as an isotonic solution.
When a solute exists in different concentrations on both sides of a semipermeable membrane.
The solute will be pushed from the place of higher concentration to the place of lower concentration, following a concentration gradient.
Particle movement in this case will stop when equilibrium has been reached, i.e. when the solute has the same concentration on both sides of the membrane.

When did evolution take place?
Answer:

Explanation:
Consider a species of sparrow that originally lived only in Alaska but recently expanded its range through North America, then Central America, and finally South America. How would you expect heterozygosity for most loci to differ among populations in North America, Central America, and South America
Answer:
North America is the one with the highest heterozygosity frequency for most loci, followed by Central America, and finally, South America with the lowest heterozygosity level.
Explanation:
Some different forces or mechanisms might alter H-W equilibrium and lead to evolution, such as mutation, natural selection, migration, and genetic drift.
In the exposed example, we have a species of sparrow that migrates from Alaska to North America. Migration is unidirectional, which means that the movement occurs in only one direction: from Alaska to North America. We should also consider that the first immigrants colonized the area for the first time, meaning that there was not a receiving population of the same species already established. Finally, we need to consider that Alaska´s environmental conditions are very different from North America´s environmental conditions.
When a species arrives at a new place, it needs to adapt. The establishment and dispersion of the species in the new area depend on previous adaptation. So, when the firsts sparrow individuals arrived in North America, they faced new environmental conditions that acted as selective pressures that drove to the occurrence of mutations. A mutation implicates a stable and inheritable change in the genetic material. A mutation introduces changes, new alleles in the population, variability. But mutation rates are very low and have no evolutive direction, so they need another force to increase or decrease the mutant allelic frequencies. Natural selection benefits new advantageous alleles and transmits them to new generations changing their relative frequencies. So, sparrows arrive in North America, mutated, and natural selection favored the beneficial mutations leading to a better adaptation to the environment. This means that the heterozygosity level in this new recent population is very high.
As animals adapt to the new habitat and have better dispersal genes, they get to disperse even more. So they start new migration south, to Central America and South America. Again, they are moving to new regions with new conditions, and to establish they need to suffer new adaptations. But remember that we are talking about a recent event in time. Probably the animals migrating south are just a few. They have not spent enough time yet in the new area, to adapt to the new environment and to include new genes into their population. What is even more, as they are a small new population moving south, they are more vulnerable to genetic drift events. Genetic drift acts on a population decreasing the variability between individuals, hence, decreasing the heterozygosity. This small population suffers low mutation, has not enough time to establish, and is more vulnerable to genetic drift events. The heterozygosity level is probably inferior to North America´s one.
Comparing the three areas, we could say that North America is the one with the highest heterozygosity frequency, followed by Central America, and finally, South America with the lowest level of heterozygosity.
