The correct answer is D. Caulerpa

Explanation:

Protists are a type of unicellular organisms that are eukaryotic which means they contain a defined nucleus but that are not plants, animals or fungus. Considering protists only contain one cell in most of the cases they are small or restricted in size this includes Dictyostelium which are microscopic organisms that consume bacteria and plasmodium. However, in the case of Caulerpa, these are not limited to size as Caulerpa is a type of alga that has macroscopic cells and indeed in some cases can be around 3 meters long. On the other hand, Ulva is also an alga but is considered in the plants' domain and therefore is not a protist. Therefore the one that contradicts contradict the statement that unicellularity restricts cell size in protists is the Caulerpa.

3. Why is it sometimes necessary to use a model that is "not to scale"?

joja [24]

My answer: Because the actual thing you might be modelling might be too small or large to replicate, (for example you cannot draw a plant cell TO SCALE because it’s way too small to see with a bare eye).
And if the item is too big, you won’t be able to fit it in a small space; if you were to draw it or create it in 3D.

I hope this helps!
Sorry if the response is too short, try rewording if you need to :)

Use the following template strand of DNA and the coding table to determine the correct amino sequence and write this sequence be

REY [17]

DNA and RNA have the main difference in the presence of deoxyribose sugar in DNA and ribose sugar in RNA. One more is the presence of thymine in DNA while the presence of uracil in RNA.

<h3>What is the codon?</h3>

Codon is actually a three-letter code which is a sequence of three consecutive nucleotides in a DNA or RNA molecule which generally codes for a specific amino acid.

The DNA sequence given here is:

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

So the RNA sequence for this will be:

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

So according to the table, the amino-acid sequence will be:

Isoleucine STOP Methionine Proline Glycine Arginine Serine STOP Serine.

Generally stop codon is responsible for the termination of protein synthesis.

Thus, this was the amino acid sequence for mRNA according to the given DNA sequence.

A scientist modified the structure of a promoter region of a gene. What could be its effect on transcription and translation?

kenny6666 [7]

RNA polymerase can't bind on the promoter region, so no transcription takes place, consequently, no protein translation.

Which source creates the most direct pollution?

Otrada [13]

Answer:

Water pollution is one of the most common type of pollution that leads to the deterioration of the water quality mainly due to the man-made interference. Direct and indirect pollution are two of its types. Direct pollution as the term suggests refers to the direct flow of pollutants in the water in contrast to the indirect pollution that accounts for the transport of pollutants eventually to the water body.

Explanation:

Direct pollution is characterized by the release of toxic fluid directly in the water body. The main source of this type of pollution are the toxic pollutants from the large factories. Some of the other sources includes solid waste from the household activities and waste from agricultural practice like fertilizers, and the waste generated by the waste water treatment plant.
