Answer:

a. Carbon dioxide is added to a five carbon sugar, making it a six carbon sugar.

Explanation:

I think this is the answer, but I'm not sure. I learned this a long time ago in Biology.

<h2>The correct answer is: Mutualism.</h2>

Explanation:

Mutualism can be defined as a type of symbiotic relationship.
Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
In the given question, some micro-organisms survive in the digestive tract of the cattle.
These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.

hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

$CO_{2}$ undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

What is the make-up (structure) of the plasma membrane? what makes the plasma membrane selectively permeable? how are the phosph

devlian [24]

Lipid bilayer model was proposed for its structure but it was modified and new structure is according to fluid mosaic model. Plasma membrane is selectively permible as it selects small molecules like lipid etc (composition is also of lipid and as solubility principle like dissolve like) so large and charged molecules like plasma and ion can't pass through it. Lipid are in form of layer so at the chain when ever other phosphate group attach the place conjugate molecule (phospholipid ) formed
