Answer and explanation;
Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.
Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.
Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.
Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.
Answer:
B
Explanation:
because they are moving at the same direction
No muscle contraction will be observed.
<h3>What is the effect of calcium concentration on muscle contraction?</h3>
The concentration of calcium ions in the muscle cells help in contraction and relaxation of muscles fibers.
Release of calcium ions initiate muscle contraction.
Therefore, there will be no contraction of muscle if calcium ions are not transported out from the sarcoplasm.

<span>In his theory, Lamarck proposed how species adapted to the changed
environment by passing down acquired physical traits to the next
generation. But, after Charles Darwin published his theory of evolution,
Lamarck's theory was rejected. Now, it is known that acquired physical traits
could not be inherited and epigenetics is a good proof for that.</span>
