Nucleic acids are long chainlike molecules that carry genetic information which is read in cells to make RNA and proteins by which living things function.
When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).
Examples:
1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.
2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein
3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).
4.exocytosis - opposite of above
Answer:
The slime mold is a protists, not a fungus. However, it has a similar appearance as a fungus but a different cell wall composition.
Explanation:
Slime mold is protist not a fungus. It is due to the composition of the cell wall. The cell wall of fungi is composed of chitin while cell wall of slime mold is made up of cellulose. The other characteristic of slime mold is the movement. They can move from one place to another like animals.
True. diphallia is a rare condition where a male has two functioning phallic organs, and it can help (if you know what i mean) sorry this was only example i could think of
I think it’s d sorry if I’m wrong
