As cell size increases the surface area to volume ratio

Biology

Answer:

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

Answer:

DNA Replication:

Replicate the following strand of DNA:

Original DNA: A T G A A C CA T T C A G T A T G G

Complementary DNA:

Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:

A T G A A C C A T T C A G T A T G G

Then the compliment is (replace with the opposite base pairs):

T A C T T G G T A A G T C A T A C C

Transcription:

Transcribe the DNA to make an mRNA molecule

COMPLIMENTARY DNA:

mRNA Molecule:

So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:

A U G A A C C A U U C A G U A U G G

Translation:

Translate the mRNA into the corresponding amino acids.

mRNA MOLECULE:

AMINO ACID:

Using the DNA sequence provided, determine the amino acids.

Next, take each codon (3-base set) to the table and record the corresponding protein:

A U G = Methionine (start)

A A C = Asparagine

C A U = Histidine

U C A = Serine

G U A = Valine

U G G = Tryptophan

ORIGINAL DNA: A T G G G T C T A G C G A A A G A T

Complementary DNA:

mRNA DNA Molecule:

Amino Acid:

And we do it all again:

A T G G G T C T A G C G A A A G A T = original DNA

T A C C C A G A T C G C T T T C T A = complementry DNA

A U G G G U C U A G C G A A A G A U = mRNA

A U G = Methionine (start)

G G U = Glysine

C U A = Leucine

G C G = Alanine

A A A = Lysine

G A U = Aspartate

Andrei [34K]

<h2>Aerobic Respiration</h2>

Explanation:

Aerobic cellular respiration is the process by which the cells of a living being separate nourishment and transform it into the energy they have to play out their essential functions
The most importance of aerobic respiration in living things can't be belittled Without this process, no living thing would survive
Oxygen is a critical component of Aerobic respiration in many animals
The motivation behind the oxygen is so significant is on the grounds that it assumes a critical job in the mitochondria, the powerhouses of the cell
The mitochondria has two layers. On the inward layer, 4 gatherings of protein structure the Electron Transport Chain

den301095 [7]

Answer:

The needed options are

A. an uncontrolled experiment

B. intuitive reasoning

C. extrapolation

D. replication

E. exploration

The ANSWER is D. replication

Explanation:

Replication in research means using the same method and methodology in proximity to the original research work.

It helps in bringing, validating and proving the original study is up-to-date. It may be done using the same exact methods in a different cultural settings, location or different research subjects to determine if the original experimental results is up-to-date.

Phantasy [73]

Pinching in of fluids by a unicellular organism is the process of pinocytosis or fluid endocytosis. The cell takes in surrounding fluids, including all of the substances available, without differentiating. It is a non-specific process. The membrane of the unicellular organism elongates, captures the fluid and small vesicles are pinched off intracellularly. These vesicles then are processed by the organelles of the cell.
