Chemoautotrophs make their own food by extracting compounds from the ocean.

Chemoautotrophs are organisms that obtain their own food (energy) from inorganic chemical compounds such as sulfur, ferrous iron, hydrogen sulfide and ammonium in their environment. These occur by chemosynthesis in which the organisms use chemical energy to produce carbohydrates. Chemoautotrophs are usually found in hostile environments such as at the bottom of the ocean or in acidic hot springs. Examples of chemoautotrophs include; thermoacidophiles, methanogens, nitrifiers and halophiles.

Although the cause of Parkinson's disease is unknown, research indicates that it may be due to defective nuclei in the cells of

kumpel [21]

Answer:

B) DNA could not be accurately replicated

Explanation:

Parkinson's disease is characterized by a deficiency in movement due to an anomaly in the nervous system of the body. However, according to this question, the cause of Parkinson's disease is unknown, although research points out that it may be due to defective nuclei in the cells of those affected.

Since Parkinson's disease is considered to be related to a defective nuclei at the cellular level, the most likely result is that DNA could not be accurately replicated. This is because DNA is located in the nucleus, and hence, a defective nucleus will affecti the DNA.

N.B: The other options are not related to the nucleus

There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many

mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:

$p^{2}+2pq+ q^{2}=1$

where $p+q=1$

And where p = dominant, and q = recessive; this means that $p^{2}$ is equal to the homozygous dominant, $2pq$ is the heterozygous, and $q^{2}$ is the homozygous recessive .

So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of $\frac{4}{100}$ or 0.04. Let that equal our $q^{2}$ value.

So when we solve for q, we get:

$q^{2}=0.04$

$q=\sqrt{0.04} =0.2$

Now that we have our q value, we can use the other equation to find p:

$p+q=1$

$p+0.2=1$

$p=0.8$

So then we can solve for our heterozygous population:

$2pq=2(0.8)(0.2)=0.32$

This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:

$0.32*100=32cats$

So now we know that there are 32 heterozygous cats in the population.

Blood contains nacl, protein, and cells. the nacl is in a(n) __________, the protein is in a(n) __________, and the cells are in

andreev551 [17]

The answers are solution, colloid, and suspension respectively.

NaCl or salt is dissolved in the blood. So this makes blood and salts a solution. You won't be able to discern the NaCl in a solution of blood and NaCl.

Proteins in the plasma make blood a colloid. Protein particles are bigger than particles in a solution but are smaller than particles in a suspension.

Lastly, blood cells and blood make up a suspension. You would notice this characteristic in blood because red blood cells settle.

You can observe this when your blood is drawn. When it is placed in a test tube and left alone or placed in a centrifuge. The components separate into liquid on top, where you cannot see particles like salt; plasma in the middle, which has pale yellow color and also contains proteins; and the red blood cells at the bottom that settled.
