Answer:
Water's high specific heat allows it to absorb a large amount of heat without changing much in temperature, keeping a relatively constant temperature in oceans and lakes which is beneficial to marine life. If water did not have a high specific heat, then it would increase in temperature very quickly and oceans and lakes would have drastic changes in temperature in very short periods of time. This could harm or kill the organisms living in them.

Answer:
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Explanation:
Answer:
If an individual has a dominant phenotype it is not known what the exact genotype is. For example with the phenotype of brown eye color , the genotype could be heterozygous.
Explanation:
Dominant is a trait that shows dominance over a recessive trait. The dominant trait might have a heterozygous or homozygous genotype.
For example, if the brown eye is a dominant phenotype, it might be that a person might have a heterozygous genotype for this trait. One of the alleles might be the dominant one while the other allele might be recessive. In such a case, the effect of the recessive trait is masked by the dominant trait. Hence, the organism shows the dominant phenotype but has a heterozygous genotype.
Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
