Identify three herbivores and carnivores from finding nemo
Minchanka [31]
<span>Okay, so herbivores are animals that feed on plants, so in Finding Nemo, those would be Bubbles (a yellow tang), the turtles, and Dory (a blue tang). On the other hand, carnivores are all animals that eat meat in order to survive, so in this cartoon, those animals would be primarily the sharks: Chum (a maiko shark), Bruce (a great white shark), and Anchor (a hammerhead shark). </span>

An organism is discovered that thrives in both the presence and absence of oxygen. Interestingly, as oxygen is removed from the
melisa1 [442]

Answer:

It is a facultative anaerobic organism.

Explanation:

This organism makes ATP (energy provider molecule) by aerobic respiration in presence of oxygen, but when oxygen is removed it is capable of switching to fermentation (sugar consumption increases and growth rate decreases).

This happens because fermentation is much less effective at producing ATP and therefore there is not enough energy for growth.

This organisms are called facultative anaerobic.

Organisms with this type of metabolism include bacteria like Escherichia coli and Salmonella or yeast like Saccharomyces cerevisiae.

Order these steps of the lytic cycle. A. Assembly B. Penetration C. Lysis D. Synthesis E. Adsorption
saul85 [17]

Answer:

The correct order is

E. Adsorption

B. Penetration

D. Synthesis

A. Assembly

C. Lysis

Explanation:

Virus can have two reproduction cycle that is lytic and lysogenic. In the lytic cycle first step is virus adsorption or attachment on the host cell surface. The second step is penetration in which the virus penetrated the host cell and injects its genetic material in the host cell.

The third step is synthesis, in this stage, the viral genome gets incorporated and produces viral proteins required for capsid formation. The fourth step is assembly in which viral protein assembled around viral nucleic and form new viruses.  

The final step is lysis where the new viruses lyse the host cell to come out of the host cell and infect other cells.
