Answer:

c. Ribosomes

Explanation:

Ribosomes can be found in eukaryotic and prokaryotic cells. In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm. In both cells, ribosomes intertwine into an RNA molecule and form polysomes.

Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.

What is the wavelength of an X-ray whose frequency is 2.0 × 1018 Hz? Hint: An X-ray is an electromagnetic wave, so its velocity

Tom [10]

Answer:

A. 1.5 × 10-10 m

Explanation:

Given the following data;

Frequency = 2.0 × 10^18 Hertz.

Speed of light = 3.0 × 10^8 m/s

To find the wavelength;

Wavelength = speed/frequency

Substituting into the equation, we have;

Wavelength = 3.0 × 10^8/2.0 × 10^18

Wavelength = 1.5 × 10-10 meters.

In foxes, silver-black coat color is governed by a recessive allele (b) and red color by its dominant allele (B), Determine the

MaRussiya [10]

Answer:

a. Genotype ratio= 1/2 BB: 1/2 Bb

Phenotype ratio= All red

b. Genotype ratio= 1/2 Bb: 1/2 bb

Phenotype ratio= 1/2 red: 1/2 silver black

c. Genotype ratio= All Bb

Phenotype ratio= All red

Explanation:

a. pure red x carrier red:

Genotype of parents: pure red (BB) x carrier red (Bb)

Genotype ratio of progeny= 1/2 BB: 1/2 Bb

Phenotype ratio of progeny= All red

b. carrier red x silver-black

Genotype of parents: carrier red (Bb) x silver-black (bb)

Genotype ratio of progeny= 1/2 Bb: 1/2 bb

Phenotype ratio of progeny= 1/2 red: 1/2 silver black

c. pure red x silver black

Genotype of parents: pure red (BB) x silver black (bb)

Genotype ratio of progeny= All Bb

Phenotype ratio of progeny= All red
