What activity is accomplished using the genetic code?cells make proteins.
RNA molecules are copied before mitosis begins.
mRNA molecules are transcribed to form tRNA.
polypeptides are made into mRNA.

Answers

(A) Cells make proteins
Proteins are composed of amino acids. Proteins are made in a process called translation, in which the cell commands.
(B) RNA molecules copied before mitosis begins
DNA molecules are copied before mitosis, not RNA.
(C) mRNA molecules are transcribed to form tRNA
DNA is used as template to form both mRNA and tRNA in a process called transcription.
(D) polypeptides are made into mRNA
mRNA is the template used to make polypeptides in a process called translation.

Therefore, A is the right answer.

Gradualism is a pattern of evolution in whichA. a single species evolves into several closely related species.
B. several distantly related species develop similarities.
C. a species evolves at a slow, steady pace.
D. a species has periods of little evolution interrupted by periods of rapid evolution.

Answers

Answer: The correct answer is-

C. a species evolves at a slow, steady pace.

Gradualism can be describesd as a pattern/ theory of evolution by which already existing species give rise to new species by means of slow/ gradual and steady changes instead of major and abrupt changes.

Over long period of time, the small changes (that are beneficial for their survival) result in new species.

Example- Tiger that is evolved pattern of stripes ( which give them better advantage to hide in tall grass).

Thus, option C) a species evolves at a slow, steady pace. is the right answer.

Answers

many trees are evergreen so that plants can photosynthesize right away when temperature rise, many trees that have needle-like leaves which shape losses less water and sheds snow more easily than broad leaves waxy coating on needle-like prevent evaporation need-like leaves are dark in color allowing solar heat to absorbed many trees have branches that droop downward to help shed excess snow to keep the branches from breaking.

During which stage of cellular respiration is glucose broken down into two molecules of pyruvic acid?a.)electron transport chain b.)glycolysis
c.)Krebs cycle
d.)acetyl CoA formation

Answers

During glycolysis, glucose is metabolised into pyruvate, which is a three carbon compound. The process takes place inside cytosol. Molecular oxygen is not involved in the same, and a little energy is produced in the form of ATP molecules. Pyruvate is then oxidised to oxygen and carbon dioxide, with further production of ATP molecules.
