<span>The paralysis is from a chain reaction of cells not processing sodium properly. This leads to their residing in a resting potential instead of forming action potentials, as is required for them to fire during muscle movements. The electrical impulses are not moving down the cells, leading to their not being able to move and, therefore, paralysis of the affected or poisoned areas.</span>

If an animal cell is placed in hypertonic solution what happens to the cell
Soloha48 [4]
<span>A solution is hypertonic to a cell if it has a higher solute (dissolved substance) concentration than the cell does. As a result, it also has a lower concentration of water than the cell does. Cell membranes and plant cell walls are semipermeable barriers, which means that certain molecules can diffuse through them, while other molecules can not.</span>

Which term is used to describe a fact that has always been observed true but could at some future time not be observed as true.A
kotegsom [21]

<u>Answer:</u>

Theory is used to describe a fact that has always been observed true but could at some future time not be observed as true.

Option: (B)

<u>Explanation:</u>

  • Hypothesis is a guess that is based upon the observation. Hypothesis is an idea that might occur in future but doesn’t fall in present theory.
  • Generally hypothesis is not based upon facts and also they aren’t proved. Interpreting certain fact is theory.
  • Theories are only the explanation of something but facts is observable.
  • Theory is something like a concept or idea that is observed to be true at present may fail in near future.
  • Law is absolute and true. Generally, they are represented by mathematical expression or equation.
  • For example, Newton's law, Law of gravity, Law of thermodynamics.

What most likely happens when lithospheric plates move apart deep below the ocean?
Alisiya [41]

Magma seeps up along plate boundaries and forms mountains.

Factor 1 creates competition and factor 2 creates genetic variation.

Explanation:

Question 1: Magma seeps up along plate boundaries and forms mountains.

When lithospheric plates move apart they create divergent plate margin where magma seeps up along the plate boundary and forms series of mountains. The mid oceanic ridge was formed this way.

  • The lithosphere lies on the weak and molten asthenosphere.
  • Different plate interactions produces a wide range of plate movement.
  • Along a divergent margin usually, two oceanic plates are forced to move apart.
  • The forces the asthenosphere to rise through seeps as magmatic bodies.
  • The rising magma them crystallizes along the margins of the plate to form mountain chains like the mid-oceanic ridge.
  • It is common to find young rocks at the plate margin and the older ones away from spreading centers.

Question 2: Factor 1 creates competition and factor 2 creates genetic variation.

Scarcity of space leads to competition between organisms and availability of mates creates genetic variations.

  • In an ecosystem with limited space, there will pressure on available resources.
  • This will lead to different organism developing strategies to efficiently adapt to their environment.
  • Organisms will in turn begin to compete with one another for the limited resources.

When we have a diverse number of mating options, genetic variation occurs. This suggests that we can have different gene combination as a result of the mating organisms.

A variation in the genetic pool of a place leads to better adaptable traits to survive the environment.
