5 0
Its so simple. Two alleles means three genotypes.
consider a gene has two alleles A(blue eyes) and a(brown eyes)
possible combinations:
1. AA - Homozygous dominant -Blue eyes.
2. Aa - Heterozygous - Blue eyes.
3. aa - Homozygous recessive - Brown eyes.

What is the process in which an mrna molecule is used to synthesize a specific polypeptide on a ribosome?.
Murrr4er [49]

Answer:

translation

Explanation:

During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
Viktor [21]

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512

Butoxors [25]
B.
