I would say B.

Because nonporous means it cannot absorb liquids or gases. That is exactly what we want. If the gases and liquids seeped through, it would mix with our water making it unsafe.

Opening K or Cl- channels in a postsynaptic membrane would produce an inhibitory postsynaptic potential (IPSP). Opening K or Cl-
Gennadij [26K]

Answer:

True

Explanation:

In inhibitory postsynaptic potentials, the opening of chlorine and potassium channels generally occurs so that chlorine enters, with a negative charge, and potassium leaves, with a positive charge. The synergistic effect of this ionic flow is the hyperpolarization of the cell, making it difficult for an action potential to occur.

Gnom [1K]

To detect immunoglobulin m (IgM)antibodies in an acute phase, blood should be collected 7 days after the onset of infection.

  • IgM and IgG antibodies to SARS-CoV-2 may both be found shortly after infection. IgG is typically detectable for extended periods of time, but IgM is most effective for diagnosing recent infection and typically becomes undetectable weeks to months after infection.
  • IgM antibody detection is frequently viewed as a sign of an acute infection. Due to cross-reactivity with IgM antibodies to other, closely related bacteria or other interfering chemicals, false-positive IgM findings are, nonetheless, frequently observed.
  • A positive IgM result may not always indicate an "acute" infection, and additional testing (such as IgG testing) may be required to interpret results because IgM antibodies may be detectable for 2-4 months (or longer) after disease resolution.
  • For many infections, the onset of a measurable antibody response is 5-7 days after the infection. If samples are taken before infection, the initial IgM test results may be negative. Antibody production Immunosuppressed patients may also continue to be seronegative.

Misha Larkins [42]

The right option is; b. the water caused an increase in temperature of the air inside the ball and an increase in pressure.

The dent (hollow area formed by pressing or hitting) from the ping-pong ball disappeared because energy was transferred from the hot boiling water in which the ball was placed to the air inside the ball. This transferred energy will increase the temperature of the air inside the ball and the air molecules will begin to move faster with a greater force. Hence, causing an increase in pressure.
