Answer:

2. mRNA/ formed from the DNA gene sequence with the help of RNA polymerase

Explanation:

Ribonucleic acid, commonly known as, RNA, is one of the two nucleic acid biomolecule. Three types of RNA exists with varying functions viz: Transfer RNA (tRNA), ribosomal RNA (rRNA), and messenger RNA (mRNA).

- mRNA is a type of RNA that is formed from the DNA gene sequence during transcription with the help of RNA polymerase. It contains codons which determine the correct amino acid sequence for a protein.

- tRNA is a type of RNA formed in the nucleus, which contains anticodons (complementary to mRNA codons) that recognizes mRNA codons and carries corresponding amino acids to the ribosome.

- rRNA is a type of RNA that makes up bulk of the ribosome (organelles for protein synthesis).

Continued strenuous activity can cause lactate to accumulate in muscles. After the activity stops, the lactate is converted into
kotykmax [81]

The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori,[1] refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.[2]

hammer [34]

Answer:

She got infected through the water she drank at the stream.

Explanation:

Protozoa is a type of pathogenic microorganisms.

Giardia are flagellate protozoa that cause the disease called giardiasis. The parasites enters the body through ingestion of contaminated food or water The food or water are usually contaminated by the feces of infected people or animals.

The protozoa attach to the lining of the host’s small intestine, where they prevent the host from fully absorbing nutrients. They may also cause diarrhea, abdominal pain, and fever.

The symptoms in the question above points to a likelihood that Terri’s sickness was caused by a Giardia protozoa.

What is the average atomic mass of a sample that has two isotopes, one with a mass of 21 amu at 62% abundance and another with a
motikmotik

Answer:

Average atomic mass = 21.38 amu.

Explanation:

Given data:

Mass of first isotope = 21 amu

Abundance of first isotope = 62%

Mass of second isotope = 22 amu

Abundance of second isotope = 38%

Average atomic mass = ?

Solution:

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (62×21)+(38×22) /100

Average atomic mass =  1302 +836 / 100

Average atomic mass = 2138 / 100

Average atomic mass = 21.38 amu.
