Answer:
Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.
Explanation:
Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.
Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.
Answer:
constant = changes and control is used as the basis of comparison
Explanation:
Constant variables are variables that do not change
e.g such as the temperature ( if it's meant to be kept at a constant temp).
Control variables are meant to be kept constant to allow for a comparison and thus determine the effect of IV (independant variable) and DV ( dependant variable)
Kinda like a pyramid. The bottom is wide, many sources of energy (plant life) that take nutrients combine them with water use the bonding of the suns rays and convert that to matter. This matter is then consumed by animals (grazers and browsers), who in turn are fed upon by predators. With man as the top predator.
Take a few seeds from wire-grass. Wire-grass grows in many natural communities, it is eaten by rodents and birds, like Quail. Quail are eaten by snakes, who are eaten by hawks, bobcats, and raccoons.
every time the meal is transferred from one critter to the next, energy is expended in the chase (heat) and capture, and energy is always being used for the animals to survive day by day.
Cell wall Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall.
