Answer:

Explanation:

Protein synthesis occurs through a chain of processes.

1) transcription of DNA in nucleus to form a RNA strand

2) RNA then undergoes modifications to form a mRNA

3) mRNA then migrates out of nuclear pore and complexes with a small and large ribosomal subunit to form a translational complex

4) translation occurs at the ribosomes to form a polypeptide by joining correct amino acids together through the formation of peptide bonds

5) polypeptide gets modified chemically and folded physically to form a protein in rough endoplasmic recticulum and golgi body.

Researchers believe that in a fish species, individuals with the recessive genotype aa are predisposed to disease. Homozygous do

Nataly_w [17]

Answer:

The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.

Explanation:

At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is

A=0.5

a=0.5

With those frequency, the expected percentage of offspring with dominant genotype will be:

AA= 0.5 * 0.5 = 0.25 = 25%

The number of homozygous dominant found is 35% which is higher than expected (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.

Four students were asked to classify the activities of the people in the picture below as examples of either potential or kineti

frez [133]

Hi there!

$\large\boxed{\text{The first choice.}}$

Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.

Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.

-----------------------------------------------------------------------------------------------------------

Looking at the examples in the table, we can sort them as such:

Girl swimming laps- Kinetic energy because the girl is in motion.

Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.

Girl hitting volleyball - Kinetic energy because the volleyball is in motion.

Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.

Therefore, the correct table is table 1.

Hypothesize why DNA replication has such accuracy

andrew-mc [135]

DNA replication has such accuracy varies. There are many DNA polymerases/repair enzymes that synthesize/repair DNA. Some are more frequent than others. The error frequency ranges between 1 to per 10,000 base pairs to 1 to per 10,000,000 base pairs, depends on the enzyme
