Answer;
A. During active transport, a material may be moved from an area of low concentration to an area of high concentration.
Explanation;
-Active transport involves movement of molecules or particles against a concentration gradient (from a region of low concentration to a region of high concentration). This movement of particles against the concentration gradient requires an input of energy from the cell in the form of ATP.
- Passive transport on the other hand involves movement of materials from a region of high concentration to a region of low concentration and does not utilize energy. Passive process are processes such as osmosis and diffusion.
To be a member of the Kingdom Animalia you would have ALL but one of these characteristics. What is not required to be classified as an animal? C. Can move/motile.
A. Water will go into the cell through the cell membrane by simple diffusion.
b. A protein will go through a channel protein that carries the protein inside the cell.
c. A Magnesium ion will pass through using charged channels.
d. A simple sugar will be carried by transmember proteins or transporters.
e. An invading bacterium will force its way into the cell by passive diffusion.
f. A lipid will be allowed to pass by lipid layers in the cell membrane.
Digestive System Organs And Its Functions
______________________________________________________________
- Mouth - digestion starts when taking a bite of any food, by chewing it allows the food to be broken down causing digestion to be easier.
______________________________________________________________
- Esophagus - is located in your throat near the trachea, it reiceve the food from your mouth when you swallow
______________________________________________________________
- Stomach - holds the food while its being mixed with enzymes that allows the food process to be broken down in a usable form.
______________________________________________________________
- Small Intestine - its made of three segements; the duodenum, jejunum, and ileum. It <span>that breaks down food using enzymes released by the pancreas and bile from the liver.

- Pancrease - first segment of the small intestion that allows enzymes to break down proteins, fats and carbohydrates. Also produces isulin.

- Liver - is to procees nutrients, to digest fats, to <span>detoxifies potentially harmful chemicals
</span>______________________________________________________________
- gallonbladder - stores <span>concentrates bile, and then releases it into the duodenum
</span>______________________________________________________________
- Collon- is <span>for processing waste so that emptying the bowels is easy and convenient.

- Rectum - <span> to receive stool from the colon,
______________________________________________________________ - Anus - </span><span>stops stool from coming out when it is not supposed to.

sorry for the lack of explanation. this too much work for me</span>
They range in size from microscopic plankton up to forms a few meters long.
