Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. These barriers are aided by various antimicrobial chemicals in tissue and fluids.


Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN. Specific defenses include antibody and cell-mediated immunity.

"what advantage do organisms that reproduce sexually have over organisms that reproduce asexually?"
makvit [3.9K]
Organisms that reproduce sexually have greater genetic and thus characteristic variations, and so, are able to withstand more selection pressures if they so happen to change or become greater. This increases the chances of survival for that species itself.

Organisms that reproduce asexually are genetically identical to each other. They are unlikely to withstand any changes in selection pressures.

Hope this helps! :)

Rank the buoyant forces supplied by the atmosphere on the following, from greatest to least: a. An elephant b. A helium-filled p
blsea [12.9K]

Answer:

a >c > b.

Explanation:

The buoyant force may be defined as the force that mainly opposes the immersed object weight. The buoyant force is greater at the bottom and acts on upward direction.

The buoyant force depend on the object of the volume and directly proportional to the volume. The buoyant force of elephant is highest as it has highest volume than skydiver and balloon has least volume and so the least buoyant force.

Thus, the answer is a >c > b.

kirza4 [7]

On land but close to oceans. Thus, option "A" is correct.

<h3>What is an earthquake?</h3>

Earthquakes occur as a result of collisions along oceanic-continental convergent boundaries.

The majority of the earthquakes occur alongside the Ring of Fire of the Pacific Ocean. The Ring of Fire is found in the basin which is a land area found close to the coastlines of the ocean. This validates its occurrence on land but close to the oceans.

Thus, option "A" is correct.
