trapecia [35]4 years ago
4 0

Answer:

<em>The correct option is D) The hind leg bones of the whales are vestigial structures that had a  function in an extinct ancestor.​ </em>

Explanation:

Vestigial structures can be described as structures or features which were once useful to the ancestor of a species but currently perform no function in the body of the organism. For example, the appendix of humans.

The hind leg bones of the whales determine that their ancestor might possess these bones for walking purposes. But as the current whales do not walk, hence these structures are vestigial for the current whales.

Which refers to swelling as a result of inflammation?
Bad White [126]

Answer: Edema

Explanation:

The swelling that is caused as the result of inflammation is known as Edema. Just after an injury takes place the traumatized area becomes red, painful and warm. It also starts to swell.

This swelled area is also known as Edema which is caused due to acute response of acute inflammation.

This response is trigerred by the injured tissues. When the body starts healing then, change in blood flow takes place and swelling is also cured.

But sometimes it is so acute that it restricts the normal blood flow and movement of the affected area.
