A predator "preys" on other animals for sustenance.
X A) decomposer because, as the name says, these organisms simply decompose dead things.
X B) producer because these organisms produce their own food instead of preying on others.
X C) herbivore because these organisms eat only vegetables and the like.
So the answer is D) carnivore because carni-vores eat meat (or carni- from the root) gained by hunting another animal.

Research this week will be done over the Respiratory system

Hitman42 [59]

Answer:

pharynx, larynx, trachea, bronchi and lungs

The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. ... The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body.

The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Describe how the output of the Krebs cycle can be modified in additional processes of the carbon cycle.

Murljashka [212]

Answer:

Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. (Note: carbon dioxide is one carbon attached to two oxygen atoms and is one of the major end products of cellular respiration. ) The result of this step is a two-carbon hydroxyethyl group bound to the enzyme pyruvate dehydrogenase; the lost carbon dioxide is the first of the six carbons from the original glucose molecule to be removed. This step proceeds twice for every molecule of glucose metabolized (remember: there are two pyruvate molecules produced at the end of glycolysis); thus, two of the six carbons will have been removed at the end of both of these steps.

Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD+, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy.

Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA. This molecule of acetyl CoA is then further converted to be used in the next pathway of metabolism, the citric acid cycle.
