Answer:

The correct answer is A. carbon fixation.

Explanation:

Carboxisomes are the microcompartment which is present in cyanobacteria and some chemotrophic bacteria which contain an enzyme called RuBisCO. This enzyme is responsible for carbon fixation in bacteria and plants.

Carboxysomes contain many polyhedron proteins that contain these enzymes which do carbon fixation in the Calvin cycle. As in carboxysome, the concentration of CO2 around RuBisCO is high so the competition with O2 is decreased or eliminated that favors carbon fixation and production of organic compounds. So the correct answer is A.

Write the number of each atom in the chemical formulas for all of the possible combinations of positive and negative ions found
adell [148]

A chemical formula is obtained from the number of atoms in a compound.

Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.

For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for suppor
omeli [17]

Answer:

<u>A. red blood cells containing malaria</u>

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite <em>Plasmodium sp.</em><em>,</em> which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they <u>burst the red blood cell open</u>, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. <u>Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.</u>
