(hope this helped if ya need more dm me on discord AkashTheMissle07#3880)

Explanation:

0.3 year ago is three hundred thousand year ago and 0.2 year ago is two hundred thousand year ago.

What is year?

Every planetary body has an orbital period, it is called as a year. when earth complete its one orbit around sun, we call it a year. Due to earth's axis, we experience seasonal changes throughout a year.

The earths rotation period is approximated into number as calendar. The modern calendar is called as Gregorian calendar represents 365 days of year, or 366 days of a leap year.

To denote period, loosely associated with it, year is used. Most civilized types of calendar used are Gregorian calendar, it uses two notions, to indicate numbering of year, AD is short form of "Anno Domini" (meaning "in the year of the Lord"), and CE is short form of "Common Era".

So basically 0.1 million year refers to 1000 000 year ago, therefore 0.3 year is 3000 000 and 0.2 is 2000 000 years.

Transcription is A. The process of making RNA from DNA. B. The activation of a gene that produces proteins. C. Irreversible changes to the DNA sequence. D. The process of making proteins from RNA

Answers

Answer: A. The process of making RNA from DNA.

Explanation:

The transcription can be defined as the process of transfer of genetic information from DNA or deoxyribonucleic acid into messenger RNA. For this double strands of DNA are separated and each strand act as a template strand for the synthesis of mRNA. The transcriptions is initiated by the enzyme RNA polymerase. The enzyme RNA polymerase utilizes DNA for synthesizing the matching complementary bases. The mRNA molecule get elongated and serves as a blueprint for the synthesis of protein in translation.

Which size cells are more efficient at obtaining nutrients?

Answers

The greater the surface-area to volume ratio of a cell, the easier it is for the cell to get rid of wastes and take in essential materials such as oxygen and nutrients. In this example, the large cell has the same area as 27 small cells, but much less surface area.
