Answer:

<em>The correct option is C) A mouse and a human have about the same number of genes.</em>

Explanation:

The technique of genetic sequencing has enable us to learn and compare thee genomes of different organisms. Genome sequencing proves that the genome of the humans and mice are about 99 percent similar. The number of genes in the mouse genome and the genome of humans is almost equal.

Other options, like option A, cannot be true because many complex organisms have fewer chromosomes than other organisms. For example, there are many simple plants which have more number of chromosomes than the complex humans.

shepuryov [24]

Answer:

end of cytokinesis

Explanation:

Telophase is the last stage of cell division. It ends with cytokinesis which is the splitting of the mother cells into two daughter cells. The cell pinches in the equator region with the help of a ring of contractile protein filaments. The formed cleavage furrow grows until the two cells pinch off completely.

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of th
Sergio [31]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.

  • <u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
  • An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.
