Streptococcus mutans is one of the bacteria responsible for dental plaque formation and lacks an outer membrane outside its cell. Structurally and morphologically how would S. mutans look under the microscope. Illustrate the appearance

Answer:

The illustration is attached.

Explanation:

Under a microscope, Streptococcus mutans would be seen as small oval structures, about 0.5 to 0.75 µm in diameter. These structures would be linked to putras in pairs, or in a type of horizontal chain.

To survive, this bacteria must be present in places rich in organic matter and nutrients.

According to the National Institute of Health, atrial fibrillation (A-F) occurs if rapid, disorganized electrical signals causing the heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In A-F, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. Based on the passage above, how will atrial fibrillation affect blood pressure?
A. It will lower blood pressure because less blood is pumped per beat.
B. It will increase blood pressure because the heart is contracting faster.
C. It will increase blood pressure because the atria fill fully with blood.
D. It will lower blood pressure because blood volume drops in the atria.

Pesticides often do not just kill the target pest but also poison

by
Unlike pesticides, fertilizers are not directly toxic but their presence in
freshwater and marine areas alters the
system, and in consequence the species
composition of specific ecosystems. Their most dramatic effect is
resulting in an
explosive growth of algae due to
nutrients. This depletes the water of dissolved
oxygen, which in turn can kill fish and other aquatic life.
