Explanation:
One major characteristic used to identify bacterial species is by Gram staining. This makes bacteria to be classified into two broad classes; Gram positive bacteria (appear purple after stain) and Gram negative bacteria (appear pink after stain).
Another characteristic used is the presence or absence of capsule.
Other characteristics include there motility (which can be due to the presence of flagella), bonding tendency (which can be individually or in pairs) and also pathogenic bacteria can be classified as intracellular or extracellular bacteria.

Answer:
Harmful algal blooms in freshwater lakes and rivers, or at estuaries, where rivers flow into the ocean, are caused by cyanobacteria, also known as "blue-green algae". They can produce hazardous toxins, such as microcystins, a neurotoxin which destroys nerve tissue of mammals.
It travels through the more dense medium until it reaches the boundary with a less dense medium. MIDDLE: At the boundary, both reflection and transmission occur. ... The reflected pulse becomes inverted when a wave in a less dense rope is heading towards a boundary with a more dense rope.
Out of the following given choices;
A) naturally acquired passive immunity; will have
B) artificially acquired passive immunity; will not have
C) artificially acquired passive immunity; will have
D) naturally acquired active immunity; will have
E) naturally acquired active immunity; will not have
The answer is B. It is
artificially acquired because it is introduced into the body and not naturally produced
by the immune system. Passive immunity <span>because
it involves immunoglobulins that are part of passive immunity of the acquired
immune system. Will not have long-term
memory passive immunity does involve T and B cells that are mainly involved in
memory of immunity. </span>
