Compare the shapes of the organisms that have cell walls with those that do not have cell walls.

Biology
1 answer:
inna [77]3 years ago
5 0
The best answer is A. The purpose of the cell wall is to hold the cell in a specific shape, usually rectangular or square. For example, a plant cell's wall keeps it rigid so that the plant can stand up. 

If the cell does not have a wall, it can easily change shape to accommodate for things coming in and out of the cell. 

Hope this helps!

30. One cause of muscle soreness is
xenn [34]

Answer:

c. lactic acid fermentation

Explanation:

If we did alcoholic fermentation, working out would make us feel drunk, not sore. This is only done by yeasts (a type of fungus) and bacteria. Glycolysis is simply an anaerobic process that occurs with fermentation and also regular aerobic respiration. It doesn't cause any soreness on its own. The Krebs cycle is the second major part to cellular respiration; it produces 6 NADH's, 2 FADH2's, 4 CO2's and 2 ATP; it's not involved in creating any soreness, as cell respiration does not create soreness. That leaves lactic acid fermentation, which we, bacteria, yeasts, and other organisms do. This is what we do when we run out of ample oxygen while doing some strenuous activity. Glycolysis is done with it. Glycolysis, however, relies on NAD+ to create ATP we need to maintain the same level of activity, lactic acid is produced as it accepts the 2 electrons and [H+] NAD+  should accept.

serious [3.7K]

Out of the following given choices;

<span>A.      </span>The mouse has a completely different DNA sequence than the other mice.

<span>B.      </span> The substituted nucleotide has the same directions as the original nucleotide.

<span>C.      </span>Substitutions in the nucleotides of a mouse's DNA never affect their phenotypes.

<span>D.      </span>DNA sequences don't determine the color of a mouse's fur.

The answer is B. Most probably, the nucleotide substitution did not translate to a change in the amino acid sequence in the translated protein. As you may be aware, most amino acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG. Therefore, a substitution, that causes a change to either one of the sequences will not change the amino acid.

Answer:

If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.

Le gabbro est une roche volcanique et grenue. vrai ou faux
zhannawk [14.2K]
Je dirais que c'est vrai car le gabbro est une roche à grain grossier et il est igné, ce qui signifie qu'il a été formé par le refroidissement et la solidification du magma ou de la lave. Je n'en suis pas tout à fait sûr, mais c'est mon avis, et je m'excuse pour toute erreur de grammaire car le français n'est pas ma langue maternelle.
