Answer:
Contractile activity of smooth-muscle cells does not normally require Ca2+.
Explanation:
There is deficiency of Smooth striations characteristic of cardiac and skeletal muscle in smooth muscle. Different organs and tube were lined with layer of Smooth muscle cell, though for contraction of Smooth muscle to occur, it's not a voluntary control
THE CONTRACTILE PROCESS
In the body of organism, the process of smooth muscle cell contraction is regulated through the activities of receptor and mechanical activation of myosin and actin which are reffered to as contractile proteins.
During the contraction process, myosin light chain kinase will phosphorylate the 20-kDa light chain of myosin, which will make the myosin to interact molecularly with actin to release Energy(ATPase). The Energy released is used for cycling of myocin and actin for contraction to take place.
Therefore,Contractile activity of smooth-muscle cells does not normally require Ca2+.
Condensing, because it is getting denser it is cramming more energy into a smaller space.
1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.
2. Adaptation is an organism changing to better themselves in a certain environment.
3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.
4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.
5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.
6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.
7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.
Answer:
because it's like sweet sugar that we uses and eats so that we put lot's of sugar in our bodies to give us more energy.

The hierarchy of species is mainly used by taxonomist in
order to classify, organize and systematize certain species in both the animal
and plant kingdom so to speak –living things. These helps them if found a new
discovered specie, they cluster it into the appropriate category into where it
fits best. There are certain factors to categorize though.
