Answer:

1. Nucleolus- inside of the nucleus, makes ribosomes

2. Rough Endoplasmic Rectilium(Rough ER)- synthesizes proteins, has sibosomes

3. Smooth Endoplasmic Rectilium(Smooth ER)- does not have ribosomes, produces protein and lipid(fat)

4. Vacuole- stores water, sugar, and pigment

5. Chloroplast- photosynthesis happens here

6. Cell Wall- provides support

7. Membrane- controls what goes in and out of the cell

8. Mitochondria- power house of the cell, produces power from chemical energy

9. Golgi Bodies- Prepares proteins and lipids for the inside an outside of the cell

10. Ribosome(the little black dots)- attaches to Rough ER, transfer RNA to protein(protein synthesis),

If the ancestral form for a particular lineage was aquatic and used gills for respiration, what changes would you expect to see

Marat540 [252]

<h2>The Respiration of Gills</h2>

Explanation:

A dominant part of aquatic animals like fish and prawns inhale through uncommon organs called gills.
The skin that help in utilizing oxygen broke up in water. which help in return of gases and Gills contain veins.
Amphibian life forms have a unique organ called gills, which permits them to inhale oxygen in the water.
The two sides of the pharynx (throat) by the Gills when the gases exchange in fish .
<em>Gills are tissues that resemble short strings, protein structures called fibers. </em>
These fibers have numerous capacities including the exchange of particles and water, just as the trading of <em>oxygen, carbon dioxide, acids and alkali.</em>

What is the most important thing that fermentation produces? Why is the product important?

NeX [460]

Answer:

Sugars are the most common substrate of fermentation, and typical examples of fermentation products are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). However, more exotic compounds can be produced by fermentation, such as butyric acid and acetone.

The initial step in the formation of an aminoacyl-tRNA is Group of answer choices esterification of the tRNA activation of the t

asambeis [7]

Answer:

The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP

Explanation:

In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.

The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.

The overall reaction step is illustrated below:

Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi
