I think it is D. You experience increase in breathing rate to obtain more oxygen which is delivered to cells through the bloodstream
Mutualism. e.g. oxpecker and zebra
commensalism. e.g. remora fish and sharks
parasitism. e.g. tapeworms and cow
Answer:
D)
Explanation:
Color is determined by a sex-linked gene, X gene, so, in order to that, the gene is maternally inherited. When one gene is related to the X chromosome, and one of the alleles is recesive and the other, logically dominant, the first generation will be of a single color, and the second generation will be of the other single color.
Answer and Explanation:
Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth
. The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting
. Even though fewer offspring are produced through this method, their survival rate is higher.
The
correct answer is they filter urea from blood and produce urine.
<span>
Nitrogenous
wastes tend to form toxic ammonia which needs to be removed. Terrestrial
animals must detoxify ammonia by converting it into a relatively nontoxic molecule-urea
(it occurs in the urea cycle). The urea cycle mainly occurs in the liver and the
produced urea is then released into the blood. It travels to the kidneys where
is filtrated and excreted in urine.</span>
