Answer:

The presence of air in the pleural cavity

Explanation:

A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.

specific macrophage populations promote both cardiac scar deposition and subsequent resolution in adult zebrafish
vova2212 [387]

Specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish. It is a correct statement.

<h3>What is the effect of macrophages on zebrafish?</h3>

There is an inflammatory response to tissue injury. It is an important part of the process of repair. Scar tissue deposition is a direct downstream consequence of this kind of response in several tissues including the heart tissue.

Adult zebrafish do not only have the ability to regenerate lost cardiomyocytes. They can also remodel and resolve a scar which is extracellular, in tissues like the heart. This resolution of the scar is a poorly understood process.

Therefore, specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish.

Select the scenarios that describe an abiotic factor that is density independent. Select the TWO answers that are correct.
kotegsom [21]

Answer: Option B and C.

Heavy and continuous rains flood the land, submerging habitats.

c. Lightning strikes a tree and begins a fire that clears the land.

Explanation:

Heavy and continuous rains flood the land, submerging habitats.

Lightning strikes a tree and begins a fire that clears the land.

The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.

Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.

Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.

Therefore, Heavy and continuous rains flood the land, submerging habitats.

cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
