Answer:
The humans use this limb to grab things, body language, and sign language.
The dogs use this limb for all kinds of weight-bearing activities like walking, jumping, running et cetera.
Birds use this to fly and whales use it as flapper.
The limbs of all these four animals are the example of homologous organs that is, they all are similar in structure but adapted to perform different functions during the course of evolution.
For example, in all four organisms, the limb is made up of the same set of bones such as humerus, radius, ulna, carpals, metacarpals, and phalanges.
Homology in structure shows that they must have evolved from a common ancestor and diverge to perform different functions as an adaptation to the contrasting environment.
Answer:
The correct answer is: neuronal cell bodies, neuropil, and glial cells.
Explanation:
Nervous tissue can easily be classified in grey and white matter. Both of these matters are located in the Central Nervous System.
These specific names are given by the color these structures have. White matter consists mostly of axons, and is white because the axons are surrounded by myelin, which is a structure made of fat.
<u>Grey matter </u><u>is composed of the bodies of neuronal cells, neuropil and glial cells. The glial cells found in the grey matter are astrocytes and oligodendrocytes.</u>
<span>Scientists use the word gender/sex to refer exclusively to biological differences between men and women in anatomy, genetics, or physical functioning. Gender/sex is determined if the person is a female or male. It’s basically the word that most of the forms have in order to know the preference of the person filling up the forms or any other documents. </span>
