<span>The ventricles are the part of the heart that are responsible for the pumping action to move blood throughout the body. Therefore, the muscles in the ventricles are much larger and thicker to do their job properly. The atrium only has to pump blood through an open valve (the tricuspid valve) into the right ventricle. There is much less resistance to this flow of blood so much less muscle is needed. </span>
1.
a. Bb
b. bb
c. Gray, because the male is homozygous recessive, which indicates the recessive trait is black.
d. Gray-Female, Black-Male
e. B b
b Bb bb
b Bb bb
f. There's a 50% chance the babies will be heterozygous (for gray) and there's a 50% chance the babies will be homozygous recessive for black.
g. There's a chance that all four offspring won't adhere exactly to the ratios predicted by the Punnett Squares, because male offspring can only have one trait (on the X).
Hope this helps. I hope you understand that heterozygous is (Big Letter & Small letter) and homozygous is either: Big Letter Big Letter OR Small Letter Small Letter. Have a great night and I hope you are successful in your class!
The right answer is D. hope this helps
Answer:
99% water, sodium chloride, trace amounts of wastes, and vitamin C
Explanation:
Eccrine glands are the main and major sweat glands of our body. These glands are found all over the skin but their density is higher on palm, soles, and head.
99% of the secretion of the eccrine gland is water and in rest 1% it contains sodium, trace amounts of waste and a high amount of vitamin C is lost by the eccrine gland.
As the eccrine gland is responsible for sweating so it helps in thermoregulation in the body. As 99% of secretion is water therefore dehydration and water loss is the major worry during excessive sweating.
The significance of elephants can be characterized as them being a Keystone species. Keystone species are usually considered to be species which have a extremely largy impact on a certain ecological niche or certain environment compared to their relative presence in that environment. In other words, while elephants aren't exactly the most numerous of species, they represent an important element of their environment which also effects other animals.
