the size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantag
professor190 [17]

Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.

Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill. Any dangerous microbial agent, including bacteria, viruses, protozoa, fungi, and helminths, might be considered a pathogen.

agasfer [191]

Answer:

Microtubules composed of tubulin protein.

Explanation:

The cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.

Microtubules are long hollo cylindric tubes with no ramifications of a diametre near to 25 nanometers. They are constituted by two subunits of tubulin protein which polymerize to form microtubules. These filaments shape the cell and are involved in intracellular transport.  Microtubules extend from an organizing center near the nucleus to the cellular surface.

When not enough oxygen is available to cells during rigorous exercise, muscle cells must convert pyruvate to __________ to gener
Kipish [7]

The correct answer is: A) lactic acid.

During the exercise, muscle cells use anaerobic respiration in order to make enough energy in the form of ATP. Anaerobic respiration doesn’t require oxygen, but glucose is broken down to produce energy. Glucose is broken down to pyruvate in the process called glycolysis. Next step is convert of pyruvate into lactic acid (or lactate).

During the exercise, the oxygen level in muscle cells decreases, which results in anaerobic respiration of the cells.
