For a neuron with an initial membrane potential at -70 mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the
The potassium ions are positively charged(cations) if the charge is -70mV the outflow of cations will cause a decrease in the potential. The potential will become lower than -70mV.
The given condition of an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the hyperpolarization of the neuron.
Hyperpolarization is a change in a cell's membrane potential becomes more negative at a particular spot on the neuron's membrane
A hyperpolarization is an event or stage that takes place when some potassium channels remain open and sodium channels reset.The sodium-potassium pump keeps the concentrations of Na+ and K+ at constant disequilibrium to set the membrane potential of neurons.Increased potassium movement leads to more potassium ions out of that neuron's cytoplasm. It can be seen as a slight dip following the spike.Thus, the correct answer would be the hyperpolarization of the neuron.

What might occur if humans reproduced through the process of mitosis?
A Many chromosomes would not be divided during cell division.
B Parents would produce more offspring.
C There would be the likelihood of an increase in genetic diversity.
D Inherited diseases would be passed down to all generations. HELPPPPP
Answer:
D
Explanation:
Mitosis creates genetically identical clones
Mitosis divides a cell into two identical daughter cells. Therefore, option (D) Inherited disease being passed down to all generations is correct.
What is mitosis?Mitosis is the process of cell division that results in the production of new cells, which are then used for growth, repair, and the general replacement of older cells. A somatic cell will undergo this process when it has to reproduce and will end up with two new cells that are an exact copy of the first. The six steps of mitosis are completed by human somatic cells in between half an hour to one hours, depending on the type of tissue that is being duplicated.
Because there is little genetic variation as a result of mitosis, each generation is at risk for the same diseases and disorders. This is one of the drawbacks of the process.
Therefore, option (D) is correct.

Read each of the answers below carefully: Which statement best describes the cell cycle? a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase. b. Cells grow and develop during the mitotic phase. Cells reproduce during interphase. c. The nucleus of the cell divides during interphase. The cytoplasm of a cell divides during the mitotic phase. d. The nucleus of the cell divides during the mitotic phase. The cytoplasm of a cell divides during interphase.
Answer:
a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.
The statement best describes the cell cycle - a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.

1- why dong you usually get sick from the exact same pathogen twice
2-if a pathogen mutated so it had different antigens, would your memory B and memory T cells recognize it?
please help this is due at 3pm
1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.
2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.
The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus
explain how darwin's journey to the galapagos islands contributed to his creation of the theory of evolutions.
Explanation:
During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.
Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.
