Biology
1 answer:
Eddi Din [679]3 years ago
8 0
MRNA, is used to transcript DNA codes from DNA molecules and then later exits the nucleus via nuclear pore, then moves to the ribosome. Then, tRNA is activated to bring specific amino acid to the ribosome for translation. Ribosome, which is the site of synthesis of proteins, is composed of rRNA and ribosomal proteins.
A codon is a three-base sequence (three nitrogen bases in a row) on mRNA. An anticodon is a three-base sequence on tRNA. It matches the codon.

Is this telophase of cytokinesis?
Butoxors [25]
Looking at the inside, it appears so.

In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.

Hope this is correct ^^

An igneous rock is found on the ground and has no identifiable crystals. What is the most likely origin of this rock?molten mate
quester [9]

The answer would be: <u>Molten material that cooled quickly.</u>


Igneous rocks are formed by the cooling of molten material. So we can cross out the last two choices. The rock has no identifiable crystals so it is most likely an Extrusive igneous rock. They form on the surface where they cool quickly.


Those that form underground are called intrusive rocks. They cool slowly allowing enough time for crystal formation.

When growing, as a cell gets bigger, what happens to its surface area to volume ratio?
marysya [2.9K]

<u>Answer</u>:

Surface area to volume ratio decreases.

<u>Explanation</u>:

When the cell enlarges beyond its capacity, it fails to supply enough material that can cross the membrane sooner so as to occupy the cellular volume. Hence the diffusion rate also decreases so as the ratio. The cell carry out its various functions to sustain through diffusion when diffusion rate is low it will ultimately affect the ratio. Bigger size affects the diffusion of the material to the out of the cell. as we know the diffusion occurs across the surface of the cell.
