Answer:
Eukaryotic microbes and prokaryotic microbes
Explanation:
Some microbes such as bacteria do not have a membrane-bound nucleus. So, their genetic material lies in the cytoplasm itself. These microbes are called prokaryotic microbes. All the bacterial species are prokaryotes. Example: <em>E. coli.
</em>
On the other hand, some microbes have a well define nucleus to house their genetic material. These microbes are called eukaryotic microbes. Fungi and protists are the eukaryotic microbes. Example: plasmodium and slime mold.
Endotherms can maintain an internal body temperature by producing energy through metabolic processes within cells
DDT has adverse affect on our environment due to its presence for a long time.
<h3>What is DDT?</h3>
DDT is an insecticide that can pass up in the food chain i.e. from insects to small birds, and then from small birds to big birds like hawks. High concentrations of DDT in birds leads to weakness in the egg shells.
This leads to a decrease in their population so we can conclude that DDT has adverse affect on our environment due to its presence for a long time.

Answer:
<u>A focal infection</u> is a small region of infection, from where the pathogen can move to other areas of the body to cause a secondary infection.
Explanation:
The focal infection theory is a theory that states that many chronic diseases (such as cancer, arthritis, mental illness) are caused by a focal infection. A focal infection is a small region of infection or a localized infected region, which can lead to a secondary infection at a site, which is susceptible to infections. Examples of such focal regions are nasal sinuses, kidney, gall bladder, liver, etc.
<u>Therefore,</u><u> a focal infection </u><u>can be defined as a small region of infection, from where the pathogen can move to other areas of the body to cause a secondary infection</u>.
