Answer:
Deoxyribonucleic Acid (DNA)
Explanation:
DNA is the chemical name for the molecule that carries genetic instructions in all living things.
Answer:
Selective permeability is a property of a cell membrane that allows it to control which molecules can pass (moving into and out of the cell) through the pores of the membrane
Explanation:
The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose, <u>Celluloso </u> and other sugars) cannot. Water can pass through between the lipids.
Explanation: your right it is bacteria , could i pls get a brainlesttttt
The answer is a very good amount.....
Protein molecules serve as transporters of molecules across the cell membrane.
Movement of molecules against their concentration gradients is a form of active transport.
<h3>What are proteins?</h3>
Proteins are organic molecules which are made from amino acids linked together by peptide bonds.
Proteins embedded in the cell membranes serve as transport molecules as well as receptors.
Based on concentration gradients, proteins can function in passive or active transport.
- When molecules move in the the direction of concentration gradient, it passive diffusion.
- When molecules move against the direction of concentration gradient, it passive diffusion.
