Answer:
Blood moves through many tubes called arteries and veins, which together are called blood vessels. The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins.
Answer:
Option B
Explanation:
The mode of speciation exhibited by these mice might follow the allopatric or peripatric pattern in that since these mice are in some ways related as stated, it is possible species C has become isolated from a peripheral population (in this case a peripatric speciation) due to maybe some geographical changes (allopatric speciation in general) as seen in vegetation changes at each elevation level and also no gene flow occurs between these population. And this depends on the number of individuals that dispersed from the original population. If large, it might be mainly by genetic drift.
Answer:
1 : 5
Explanation:
Ratio is used to show the relationship between two amounts. It tells how many one value is contained within another value. Ratio can be used to compare the size of two or more numbers in relation to each other.
The comparison between this two numbers or quantities is done and expressed by division.
Ratio of triangles to squares = number of triangles : number of squares
Ratio of triangles to squares = 4 : 20
Ratio of triangles to squares = 1 : 5
75% (3/4)
there would be BB, Bb, Bb and bb
BB and Bb are the only ones that is dominant since bb is recessive.
Adenine always pairs with Thymine, and Cytosine always pairs up with Guanine in DNA. When dealing with RNA, however, Uracil replaces Thymine. So in RNA, A pairs with U and C pairs with G. (just a fun fact) :)
