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+.
Answer:
There are three steps to genetic engineering. They are (1) The isolation of DNA fragments from a donor organism; (2) The insertion of an isolated donor DNA fragment into a vector genome and (3) The growth of a recombinant vector in an appropriate host.

Answer:
When a water and limestone slurry is used as a scrubber, the impact of modifying the slurry by increasing the amount of limestone has as a consequence that the amount of sulfur dioxide released will decrease.
Explanation:
One of the consequences of the use of coal as fuel is the emission of toxic gases, one of which is sulfur dioxide (SO₂), a colorless and toxic gas that can affect the health of humans and animals. That is why SO₂ scrubbers are necessary for the removal of this gas.
One of the most commonly used SO₂ scrubbers is the suspension of water and limestone, since the calcium (Ca) contained in the limestone reacts with the SO₂ to form calcium sulfide (CaS), which precipitates as a solid, decreasing the emission of SO₂ to the environment.
It is for this reason that, by <u>increasing the amount of limestone in the scrubber slurry, more SO₂ will react, and the amount released from this gas will decrease.</u>
