Facilitated diffusion occurs with the help of a transport protein, such as electrons passing through ATP synthase in the electron transport chain.
<span>Homeostasis Body's tendency to maintain a steady internal state; physiological equilibrium or balance around an optimal set point. [hot=sweat, cold=shivers]
Janice sweating on the treadmill in order for her body to cool off is an example of Homeostasis. Homeostasis is the body's ability to keep a steady internal temperature, state, equilibrium or balance around the ideal set point. This means when you are hot, you sweat to cool the body down and when you are cold your body shivers to help warm it up.</span>
A phylogenetic tree based on morphology can be constructed using the presence or lack of characteristics. In this illustration, all aliens except the outgroup possess a spring tail, all aliens possess a fourth eye, two aliens possess two tails, and one alien has a grasping hand. The evolutionary relationships between these organisms can be hypothesized using these traits.
Aliens:
- We can determine whether the following traits are present in the remaining aliens by using the group of aliens with the tail stalk as our test group.
- Out group: a group that is maintained apart from the clade but is yet connected to it.
- If we provide these aliens alphabets for ease of understanding, then aliens will be like in order.
- We can use the group of aliens with the tail stalk as our test group to see if the following characteristics are present in the remaining aliens.
- A group that is kept separate from the clade while yet being affiliated with it is known as an out group.
- The aliens will appear to be in order if we give them alphabets for simplicity.

It tells you that they descended from a common ancestor.
The correct answer is option 3, that is, the muscular system, to extend, flex, and rotate the muscles with smooth, and coordinated effort.
The musculoskeletal system provides support, form, movement, and stability to the body. It comprises the bone of the skeleton, cartilage, muscles, ligaments, tendons, joints, and other connective tissue, which holds and supports organs and tissues together.
The flexing, extension, and rotation of the muscles with smooth and coordinated effort makes sure the movement of fluid in the human body.
