Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️
Explanation:
germ cells
it occours in the germ cells
Answer:
a. It has a negative value.
b. It is measured in millivolts.
c. It is measured in millivolts.
Explanation:
Resting membrane potential is typically ~ -70 millivolts so options a, b and c are correct, rest are false statements.
The resting membrane potential is -70 millivolts because more K+ is inside the neuron while more Na+ is outside the neuron and it reflects more negative voltage in the cytosol as compared to the interstitial fluid.
As soon as stimulus arrives, it causes more Na+ to move inside the neuron making the membrane potential as +20 millivolts and the neuron is said to be in 'depolarized state'. Soon after that K+ starts to move outside of the neuron and since K+ has positive charge and it is moving out of the cell so the membrane becomes more and more negative inside and at this time neuron is said to be in 'hyperpolarised state'.
Answer: C. Oxygen delivery to muscle is increased when more carbon dioxide is produced by the muscle.
Explanation:
When someone is doing an exercise, for example, his heart rate increases. This increases the rate at which oxygen is carried from the blood to the muscles and carbon dioxide is moved from the muscles to the lungs, where it will be breathed out.
