What are Smooth muscle cells?
Smooth muscle cells are also called as involuntary muscle cells. These muscle shows no cross stripes under microscopic magnification. Muscle cells are made up of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike the striated muscle, contracts slowly and automatically in the body.
At a cellular level, smooth muscle cells can be described as an involuntary, non-striated muscle cell. Smooth muscle cells consist of alternate thick and thin filaments which are not arranged into sarcomeres however it gives a non-striated pattern. On further microscopic examination, it appears homogenous.
Therefore, the correct option is C.

After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

A new microbiology student failed to properly sterilize the pipet between creating E. coli and S. epidermidis cultures from the tablets in the lab kit. How would this mistake be recognized when the mixed culture is streak plated
With this error, the culture medium can be visualized with two different types of bacteria, with different stains.
In addition to staining in culture medium, what are the differences?Escherichia coli, or E. coli, is a bacterium that naturally inhabits the intestines of people and some animals, without any signs of illness.
Staphylococcus epidermidis is a Gram positive, coagulase negative bacterium that is part of our normal flora. The microorganism colonizes human skin and mucous membranes, notably moist surfaces such as armpits, nostrils, etc.
With this information, we can conclude that this error, the culture medium can be visualized with two different types of bacteria, with different stains.

Researchers use all of the following to study the impact of heredity on behavior except peer.
Researchers use all of the following to study the impact of heredity on behavior except why?
When looking at studies relating to the heredity of traits we want to see if the child got a trait from the parents and their genes or from the way the child grew up with the parents.
That means that peers are not useful to us in those studies. Family is very useful since we need to look at the family and how it raises a child. Adoption is useful to see if an adopted child has the same traits as a biological child.
And twins are useful if they grew up in different circumstances from one another.

The pulmonary circulationThe circulatory system is divided into two main parts namely:
pulmonary circulation and systemic circulation.The pulmonary circulation involves the movement of blood between the lungs and the heart.
Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.
After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.
