No 2 people in the world are "exactly alike", so the odds would be 0% chance. Twins, might be closer in alike-ness, but they still aren't "exactly alike". Hope this answered your question.
When a nerve impulse reaches the end of an axon, the axon terminal released ACh into the synaptic cleft. 2. ACh diffuses across the cleft and attaches to the ACh receptors on the sarcolemma of the muscle fiber. 3. ACh binding triggers electrical events that ultimately generate an action potential.
Answer:
The area under a speed-time graph represents the distance travelled.
Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.
