When the neuron is at rest, what is primarily responsible for moving potassium ions OUT of the cell?

a concentration gradient

an electrical gradient

both a concentration gradient and an electrical gradient

the sodium-potassium pump

Answer:

a concentration gradient

Explanation:

At rest, the sodium-potassium pumps pump the two potassium ions into the cell for three Na ions moved out of the cell. This creates a higher potassium concentration gradient inside the cell. This concentration gradient moves the K+ out of the cell. Movement of positively charged K+ out of the cells make the inside of the membrane negative with respect to the outside. This is how the negative resting potential is maintained when neurons are nor firing the action potential.

Which statement describes the reaction for cellular respiration? The equation is carbon dioxide + water Right-arrow glucose + ox
ziro4ka [17]

Answer:

glucose + oxygen Right-arrow carbon dioxide + water and energy is produced in the form of ATP. This is the correct equation.

Explanation:

In cellular respiration -

If oxygen is present glucose molecules breakdown release energy in the form of ATP.

Here 1 glucose molecule in the presence of 6 oxygen molecules gives 6 carbon dioxide and 6 water molecules And 36 ATP as energy.

aerobic cellular respiration is very efficient in energy production as it gives high energy.

A student investigated whether ants dig more tunnels in the light or in the dark. She thought that ants used the filtered light
allsm [11]

Answer:

Please see below

Explanation:

  1. Source of light, measuring tool (the string and ruler), ant food, ant farms
  2. Whether or not the tunnels created by ants differ in length depending on the amount of light available
  3. More tunnels are dug by ants during the daylight hours
  4. The hypotheses will probably come out to be true since ants are usually hiding away from predators during the night
  5. The presence of light
  6. The length of a particular tunnel
  7. Perform a trial under normal conditions (room light)
  8. Inaccuracy or inconsistency in measurements

The pedigree below tracks Duchenne Muscular Dystrophy (DMD) through several generations. DMD is an X-linked recessive trait.
Goshia [24]

Answer:

- If individual III-1 marries an unaffected, non-carrier female, none of their children will have DMD

Explanation:

From the options, the only correct statements is that  <em>If individual III-1 marries an unaffected, non-carrier female, none of their children will have DMD</em>

<u>DMD is an X-linked recessive trait, meaning that a male individual is either affected or unaffected (can never be a carrier). III-1 is unaffected and if he marries an unaffected, non-carrier female, it means that none of their children will have DMD.</u>

All the children of II-4 and II-5 will always come out with DMD because both parents are affected.

Individuals I-1 and II-1 are males. A male can never be a carrier in for X-linked traits. He is either affected or unaffected and as shown by the pedigree, both males are unaffected (unshaded).
