Answer: Although the Moon appears to shine, it does not emit light. Instead, we can see the Moon because it is lit up by the Sun.

Explanation:

The part of the Moon that is both sunlit and facing Earth is called the Moon's phase.

As the Moon orbits Earth, the Moon's phase changes. The model below shows the Moon's phase at eight positions in its orbit. The smaller moons closer to Earth show where sunlight hits the Moon. The larger moons farther from Earth show how the Moon will look during that phase.

<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

  • The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
  • Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

  • All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
    A semipermeable lipid bilayer makes up the cell membrane.
  • The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

  • The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .

Science is best known for logics.

Science is so interesting such that it method of processing and validating logics and facts with verifiable hypothesis and experimental evidence.

This scientific method is also an empirical method of acquiring knowledge which simply involves making observation, establishing hypothesis, designing experiment, analysing result and drawing conclusions.

A hypothesis is a reasonable explanation for a particular observed natural phenomena.

<h3>What is science?</h3>

Science can simply be defined as the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.

So therefore, science is best known for logics
