Answer: By Hormonal action and Nervous coordination
Explanation:
Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.
Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.
For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.
Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc
So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
Options for the question are not given. They are as follows :
A. Mate them and see what color the offspring are—that will be the dominant color
B. Mate them and see what color the offspring are—the other will be the dominant color
C. Mate them, and then mate their offspring to see what color the next generation is
D. Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color
Answer:
A. Mate them and see what color the offspring are—that will be the dominant color
Explanation:
Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.
When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.
Answer:
a.
Explanation:
pathogens may enter the body and cause illness.
Answer:
The use of heat to burn foodstuffs
The use of chemical energy to transport organelles through the cytosol
Explanation:
In plant cells, sunlight energy is converted into chemical energy in a process known as photosynthesis which happens in the chloroplast.
During respiration, cells generally metabolize nutrients to produce useful energy in the form of ATP.
<em>Heat is not used to burn foodstuffs in any cell while organelles are not transported through the cytosol in any cell.</em>
