Answer:
3
Explanation:
1. Incorrect - that is the rough ER (endoplasmic reticulum)
2. Incorrect - vacuoles don’t contain DNA. That is the nucleus
3. Correct - that is the mitochondria and respiration, the process of turning compounds into energy, takes place
4. Incorrect - that is the cell membrane, but it doesnt provide rigid support for the cell; the cell wall does
I hope this helps!!! :)
Answer:
The answer is A) Homologous structures
Explanation:
Homologous Structures:
- Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
- Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
- For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.
- Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
- Inherited and developmental are out of context in terms of evolutionary relationships.
This one would be amplitude. The reason is because amplitude is the distance from the center of the wave to the farthest point on the wave. So, if the amplitude of a wave is, say, 5m, the distance between the center of the wave and the top (or bottom) would be 5 meters. And to find the total height, just double the amplitude.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
- How to bring the information from the nuclear DNA to the place of protein synthesis?
- How to convert this DNA information into amino acids and then into proteins?
Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
<h3 /><h3>How to bring the information from the nuclear DNA to the place of protein synthesis?</h3>
The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
<h3 /><h3>How to convert this DNA information into amino acids and then into proteins?</h3>
Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.
