All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity. Homeostasis is necessary for normal life processes that take place inside cells.
Answer:
Bacterial plasmid are easily gotten from commercial suppliers, controlled to produced recombinant plasmits through the process of inserting foreing DNA, before it is introduced into bacterial cells.
and is prevented in the absence of , which causes calcium to trigger contraction through a response with regulatory proteins.
and filaments of the fibrils glide into one another as a result of calcium diffusing in the cytoplasm, resulting in the of the complete muscle fiber. The SERCAs pump (Sarcoplasmic/endoplasmic reticulum calcium ATPase) actively pumps ions back into the sarcoplasmic reticulum when the action potential decays.

Answer:
Complex organisms evolved from more simple organisms
Explanation:
<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>
<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>
The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.
