The best answer is A. The factor that may have led to the snails extinction is that there is an increase buildings on the islands. The Hawaiian tree snail lives in moist rainforests. They are listed as endangered due to human disturbances. The threat came when the first settlers in Hawaii began cutting trees, replacing their habitats with agricultural lads, buildings and other infrastructure.

The second electron transport chain ends with a(n) ______ that creates NADPH.
mote1985 [20]
1. The right answer is enzymes
NADPH are molecules which are produced during reduction of metabolites (for example glucose metabolism, lipid metabolism...)

2. The right answer is enzymes.
<span>The dark reactions (carbon cycle) act by the reduction of carbon dioxides (CO2) to the level of a carbohydrate (like fructose).
</span>
3. The right answer is ATP.
ATP, or adenosine triphosphate, is a nucleotide of the purine family used to store and transport energy (purines are nitrogenous bases).

4. The right answer is the Calvin cycle.
The Calvin cycle is a series of biochemical reactions that take place in plant chloroplasts. The Calvin cycle makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.

5. The right answer is NADH
The overall assessment of glycolysis is:Glucose + 2 ADP + 2 Pi + 2 NAD + -----> 2 pyruvate + 2 ATP + 2 H2O + 2 NADH
As we can see, the glycolysis produce indeed 2NADH from a reduction of metabolites during the process.

6. The right answer is Glycolysis.
Glycolysis is the first chain of carbohydrate catabolism, it is carried out in the cytosol by soluble enzymes and anaerobically (without oxygen supply). Its function is the synthesis of a molecule rich in energy, as well as the formation of pyruvate which will have several destinies, including the Krebs cycle.
<span>The Krebs cycle (or tricarboxylic cycle or citric acid cycle) is the energy platform of the cell, continuing the catabolism of carbohydrates after glycolysis. It is realized in the mitochondrial matrix and is done exclusively in aerobic.</span>

What is the key difference among the 20 amino acids that are used to make proteins?
Ray Of Light [21]

Answer:

Attached R side groups

Explanation:

The proteins are one of the important biomolecules which are directly coded by the genetic material of an organism.

The proteins are composed of the amino acids which possess, an amine group, a carboxylic group and an attached side group called the R group.

It is the R group of an amino acid which determines whether the amino acid will a polar or a non-polar amino acid molecule thus it determines the properties of the amino acid in terms of chemical properties. The R side group are involved in the formation of bonds with the substrate of the environment and the tertiary structure of the proteins.

Thus, the presence of different R group is the key difference in 20 amino acids.

WHICH STATEMENT IS the strongest evidence in support of endosymbiotic theory of eukaryote evolution
wlad13 [49]

Answer:

Please see my answer below.

If you like my response you can mark it as brainliest.

If you have any doubts (no joke) you can reach out to me in the comments.

Explanation:

<em><u>The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.</u></em>
