Avoid touching it, if a mole is picked at and is expanding this can becaome a serious problem causing infection if picked at, if it continues to grow you might needd to see a doctor or a dermatologist
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
The correct answer is diffusion.
Aquatic respiration refers to the procedure whereby an aquatic animal attains oxygen from water. Fish and other aquatic species utilize gills to consume oxygen dissolved in the water and diffuse carbon dioxide out of the bloodstream.
Diffusion is a procedure in which a substance moves from a region of high concentration to the region of low concentration until equilibrium is attained. In the case of aquatic species, blood with a low concentration of oxygen molecules moves through the gills. The concentration of the oxygen molecules in water is greater in comparison to the concentration of oxygen molecules in the gills.
As a consequence, the molecules of oxygen diffuse from water (higher concentration) to a region of lower concentration, that is blood. In the same manner, the molecules of carbon dioxide diffuse from the blood, that is, high concentration to water, that is, low concentration.
Heterozygous is when an individual has two different alleles at any location. In this example, each parent will have Pp for tail type and Ll for eyelash length.
The punnet square for couple will look like this
PL Pl pL pl
PL PPLL PPLl PpLL PpLl
Pl PPLl PPll PpLl Ppll
pL PpLL PpLl ppLL ppLl
pl PpLl Ppll ppLl ppll
Of the sixteen genotypes listed, the following phenotypes will result
Polka dot tail with long eyelashes 9
Polka dot tail with short eyelashes 3
Solid tail with long eyelashes 3
Solid tail with short eyelashes 1
I want to say the answer is (C), but it looks like there might have been an error in the question where it says 3 solid tails, short eyelashes and then 1 solid tail with short eyelashes
