gladu [14]

Answer:

Mammals

Birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job.  For example, the wings of bats and birds.

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.
hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

CO_{2} undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.
