The symptoms of a lung-expansion injury tend to appear _____ while the symptoms of decompression sickness tend to appear ______.
Margarita [4]

The symptoms of a lung-expansion injury tend to appear immediately after the dive while the symptoms of decompression sickness tend to appear usually slower after the dive.

Why does oxygen treat scuba-related illnesses?

Decompression sickness (DCS) patients address the disease process by dissolving air bubbles in the blood and tissues and diffusing excess nitrogen to oxygenate ischemic regions.

Needs to be recompressed Recompression was traditionally carried out with the assistance of a personal doctor or technician and a customized chamber that allowed for a controlled rise in atmospheric pressure. DCS divers have to travel further to decompression rooms since the number of rooms accessible for 24-hour emergency care countrywide is decreasing at an alarming rate.

Harlamova29_29 [7]

The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.

Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.

Yanni made a chart to compare the strong and weak forces. Which best describes Yanni’s error? Only the weak force is active in t
cluponka [151]

Answer: Option (d) is the correct answer.

Explanation:

Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.

But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.

This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.

Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.

Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
