Answer:
a or b
Explanation:
sorry cant really classify it brainlest on the effort tho?
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
Answer:
The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.
Explanation:
In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.
Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.
