A neuron can receive thousands of EPSPs from different neurons, and responds by triggering or not triggering an action potential
Korvikt [17]

Answer:

The addition and response to the net effect of postsynaptic potentials is called Spatial summation

Explanation:

Signal summation occurs when impulses received by a neuron are eummed together to reach the excitation threshold to fire a neuron. It occurs at the axon hillock of a neuron. Signal summation occurs since each neuron is connected to many other neurons, often receiving multiple impulses from them, both excitatory and inhibitory.

Signal summation can either be temporal or spatial.

Temporal summation, occurs when impulses received at the same place on the neuron in close temporal succession add up to initiate an action potential in the neuron.

Spatial summation occurs when impulses received simultaneously at different places on the neuron add up to initiate an action potential in the neuron.

The presence of paired chromosomes makes a diploid/germ/haploid/gamete cell, while a single member of a pair of chromosomes make
geniusboy [140]
The presence of paired chromosomes makes a <u>diploid </u>cell, while a single member of a pair of chromosomes makes a<u>haploid </u>cell.

Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>

What do you think will happen to the planet if plants are drastically reduced in population or become extinct?
Inessa [10]

Answer:

If all the plants on earth died, so would the people. ... When green plants make food, they give off oxygen. This is a gas that all animals must breathe in order to stay alive. Without plants, animals would have no oxygen to breathe and would die.
