2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.

3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.

Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?

Answers

Answer:

RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.

These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.

Action Potential: Relative refractory period
In a neuron, there is a period of time called the absolute refractory period where it is impossible for an action potential to
begin. This corresponds to the change in membrane potential from +30 to -70 mV, or the repolarization phase. Towards the
end of the repolarizing phase, there is a relative refractory period where it is difficult, but not impossible, for another action
potential to begin. Using the time slider function, which of the following segments in the neuron would correspond to a
relative refractory period?

Answers

A second action potential can be triggered during the relative refractory phase, but it will need a stronger stimulus to do so than the first time. Refractory times are brought on by the inactivation gate of the Na+ channel.

What Action Potential related to Relative refractory period?

The axon has a tougher time producing successive action potentials during this time period, which is referred to as the refractory period, as a result of these transient alterations.

As a result, the refractory period restricts the quantity of action potentials that a certain nerve cell can generate in a given amount of action potentials time.

If enough powerful stimuli are applied to the neuron after the absolute refractory time, Na+ channels start to recover from inactivation and the neuron may respond once again by generating action potentials.

Therefore, A stimulus that is stronger than usual is required to generate neuronal activation during the relative refractory period.
