What is:<br> Behavioral isolation Temporal Isolation <br> Habitat Isolation
maksim [4K]

Answer:

*Behavioral isolation occurs when members of a population diverge in their behaviors over time. Eventually, they are unable to mate and become separate species

*Temporal isolation, in biology, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.

*Habitat isolation occurs when habitat preferences lower the probability of mating between individuals associated with differing habitats.

Why are the cartilage rings in the trachea important? What do you think would happen if they were not there?
timama [110]

Answer:

The trachea, commonly known as the windpipe, is a most important organ as it allows the passage of air into the lungs. Because the trachea has a soft tissue tubular formation, it needs a base of stronger, yet flexible stuff that will give it support, protect it, and still allow the passage of air into the lungs.

This is precisely the task of the tracheal rings, or cartilage rings in the trachea. These rings are made out of cartilaginous tissue, which is much stronger than the soft tissue of the tubule, but are still flexible enough to not close down the tube when air is flowing in. Thus, the tracheal rings have two tasks: one, provide support and protection for the much softer and more vunerable tube of soft tissue through which the air passes, and two, provide flexibility so that air can flow easily.

If these tracheal rings did not exist, if they are crushed, or removed, a person´s trachea would simply collapse and the person would die as air would not be able to flow through to the lungs.

Sometimes new information results in minor changes to a theory. But sometimes new information results in a theory being discarde
Pavlova-9 [17]

Dalton's atomic theory is an example of an incorrect theory that was disproved by the discovery of new information.

<h3>Which theory was proved wrong due to new information?</h3>

An example of an incorrect theory that was disproved by the discovery of new information is Dalton's atomic theory because when the sub atomic particles are discovered, this theory was proved wrong.

So we can conclude that Dalton's atomic theory is an example of an incorrect theory that was disproved by the discovery of new information.
