A male with a mutation in a gene on the X chromosome is typically affected with the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females.

The output region is the site of ______________________.
tester [92]

Answer:

The correct answer is option C (voltage gated Na+ channels).

Explanation:

Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.

The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.  

At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.

Thus, option C (voltage-gated Na+ channels) is the correct answer.

If a germ-line cell from a frog contains 10 picograms of DNA during G1 of interphase, then how many picograms of DNA would be pr
DIA [1.3K]

Answer:

10

Explanation:

The cell cycle is composed of three states: interphase, cell division and resting.

The interphase is composed of 3 phases: G1, S and G2 (in this order). During this state the cell prepares itself  for cell division. As part of the preparation the cell duplicates all its genetic material, that is, all its chromosomes. This duplication is done during the phase S.

During the meiotic cell division (composed of meiosis 1 and meiosis 2) a single diploid mother  cell (with duplicated chromosomes) produces four haploid daughter cells. the meiosis 1 produces two haploid cells with duplicated chromosomes, and the meiosis 2 produces 4 haploid cells with normal chromosomes (no duplicated).

If a germ-line cell from a frog contains 10 picograms of DNA during G1, then this cell will have 20 picograms of DNA before the product of the first meiotic division, and will have 10 picograms at the begining of the meiosis 2 (i.e prophase II)
