Simply, translation is a copy of _______________a. DNA from mRNA
b. DNA from DNA
c. protein from RNA
d. RNA from DNA

Answer:

1/8 Red, polled

1/8 Red, horned

1/4 roan, polled

1/4 roan, horned

1/8 white, horned.

1/8 white, horned.

Explanation:

Roan cow with heterozygous horned genotype = RWPp

Roan, horned bull genotype = RWpp

Crossing the two:

RWPp   x   RWpp

Offspring:

2 RRPp = Red, polled

2 RRpp = Red, horned

4 RWPp = roan, polled

4 RWpp = roan, horned

2 WWPp = white, polled

2 WWpp = white, horned.

Hence, the phenotypic ratio is:

1/8 Red, polled

1/8 Red, horned

1/4 roan, polled

1/4 roan, horned

1/8 white, horned.

1/8 white, horned.

Answer:

The phenotypic ratio of the cattle offsprings is as follows:

Red polled = 1/8

Red horned = 1/8

White polled = 1/8

White horned = 1/8

Roan polled = 2/8

Roan horned = 2/8

Explanation:

This is a cross involving two genes; one coding for coat color and the other for horn in cattle. The alleles of the first gene (Red, R and White, W) are codominant i.e. will both be expressed in a heterozygous state (Roan, RW). The polled allele (P) is dominant over the horned allele (p) in the second gene.

According to the question, a roan cow that is heterozygous for the horned gene will have genotype, RWPp while a roan bull that is horned will have genotype, RWpp. Hence, in a cross between these two cattles, each parent will undergo meiosis to produce the following possible gamete combinations;

RWPp- RP, Rp, WP, Wp

RWpp- Rp, Rp, Wp, Wp

These gametes used in a punnet square (see attachment) will produce 16 possible offsprings with 6 distinct phenotypes. The phenotypes are:

Red polled (RRPp or RRPP) = 2/16 or 1/8

Red horned (RRpp) = 2/16 or 1/8

White polled (WWPP or WWPp) = 2/16 or 1/8

White horned (WWpp) = 2/16 or 1/8

Roan polled (RWPP or RWPp) = 4/16 or 2/8

Roan horned (RWpp) = 4/16 or 2/8

Answer:

Alveoli

Explanation:

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Answer:

Although the blood of the fetus and the mother does not mix,  Simple diffusion across the membrane of the placenta occurs.And since diffusion is the movement of ions and gaseous molecules across the membrane from the higher concentration of the mother blood to the lower concentration of the fetus, toxic chemical are conveyed across.,

Explanation:

Answer:

10m/s

Explanation:

Given parameters:

Frequency of wave  = 2Hz

Wavelength = 5m

Unknown:

Speed of the wave  = ?

Solution:

The speed of a wave is derived from the product of wavelength and frequency;

     speed  = frequency x wavelength

Insert the parameters and solve;

    speed  =2 x 5 = 10m/s

The study of cells is called cell biology. There are two types of a cell on the basis of their number and these are unicellular and multicellular.

The correct answer to the question is option C that is insertion mutations can affect many amino acids in the protein.

What is transcription?

• The conversation or transferring of the gene from DNA to RNA is called transcription.

What is mutation?

• The abnormality in the gene in the DNA sequence which forms a mutated protein is called a mutation.

The formation of protein is called translation. This addition of genes changes the sequence of RNA which alters the protein formation while in point mutation it changes only one amino acid.

Hence, the correct answer is option C.
