Set up your punnet square (attached)
You get:
PP = polkadot = 1 = 0.25
Pp = polkadot = 2 = 0.50
pp = solid = 1 = 0.25
ANSWER: D
The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
I’m pretty sure the answer is C
answer; Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. ... Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Updated January 06, 2020. A gene is a portion of DNA that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color. Genes come in multiple forms or versions. Each of these forms is called an allele

The right option is; nucleotides
Nucleotides are the building blocks of DNA macromolecules.
Nucleotides are the building blocks (monomers) that make up a DNA molecule. Each nucleotide that constitutes DNA has three components which are; a five-carbon sugar (ribose or deoxyribose), a nitrogenous base, and a phosphate group. Nucleotides perform several important roles in the cell. They transfer chemical energy to cellular functions that require energy such as in proteins synthesis, and in the movement of the cell. Nucleotides are also involved in cell signaling.
