Answer:
The answer is A. Heterozygous
Answer:
B) temporal summation
Explanation:
When two EPSPs occur at the same synapse, the process called temporal summation occurs.
Temporal summation is the process of combining the postsynaptic potentials of different neurons as they are added in sequence.
When occurring in rapid succession, the final potential becomes a cohesive sum of the postsynaptic potentials. Therefore, temporal summation can be defined as the sum that creates postsynaptic potentials at different times.
Answer:
d. K+ and Na+ both diffuse into the cell along their concentration gradients and drive the transport of glucose.
Explanation:
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
Answer:
the long haired trait was the dominant trait and the short haired one was the recessive trait
Explanation:
in a species of mice, short hair is dominant to long hair. if a short-haired individual is crossed with a long-haired individual and both long- and short-haired offspring result, one can conclude that the long haired trait was the dominant trait and the short haired one was the recessive trait
