Answer:
The first one is the correct answer
Explanation:
Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. In addition, suppose that a dominant allele (L) codes for long eyelashes and a recessive allele (l) codes for short eyelashes. If two individuals heterozygous for both traits (tail color and eyelash length) mate, the probability of the phenotypic combinations of the offspring will be in the ratio, D. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and short eyelash).
The solution is found by solving a Punnett square shown in the image.
Answer:
Nitrogenous base
Explanation:
Phosphate and deoxyribose create the "backbone" of a DNA molecule.
Think of the molecule as a ladder.
These(deoxyribose and phosphate) are the sides of the latter.
The nitrogenous bases(A,G,C,T) are the rungs of the ladder.
As the arrow points to the "rung" of the ladder, that means it is a nitrogenous base.
<span>The question says, the tendency of water molecules to attract one another due to polarity is called .....................The correct answer is Cohesion. Cohesion is the attraction of water molecules to one another while adhesion is the attraction of water molecules to other substances. Cohesion of water molecules occurs as result of charge differences between the molecules of water.</span>
