Answer:
Make an observation, create a hypothesis, test the hypothesis, draw conclusions and refine the hypothesis.
They test the hypothesis by stating the hypothesis, formatting an analysis plan, analyzing sample data from experiment, then interpreting the results in the conclusion.
The archaea are in a different domain from bacteria due to certain differences in their morphology and habitats, the Archaea are the separate domain of life in prokaryotes. For example; unlike bacteria, archaea cell walls do not contain peptidoglycan, they have different membrane lipid bonding from bacteria and eukarya.
Archaea is considered as the different domain of life in prokaryotes, as they are the most primitive type and known as the ancient microbes found in extreme niches such as hydrothermal vents, higher salt concentration, high temperature, and pressure etc
Through the use of the capsule, the pathogenic streptococcus pneumoniae's virulence factor supports survival by inhibiting bacterial adherence to phagocytes.
<h3>What is Streptococcus pneumoniae,</h3>
Streptococcus pneumoniae, also referred to as pneumococcus, is a spherical, gram-positive, anaerobic species of the genus Streptococcus that is capable of alpha- or beta-hemolysis. They frequently exist in pairs, don't make spores, and are stationary. Streptococcus pneumoniae is the most frequent cause of middle ear infections, sepsis (blood infection) in children, and pneumonia in elderly and immunocompromised individuals. Meningitis, an infection of the membranes that protect the brain and spinal cord, or sinus infections may also occur from it. A serious human pathogen is Streptococcus pneumoniae. An essential virulence factor is the pneumococcal capsule's thickness, which reduces phagocytosis.

The answer to 21 is C. Sex Cells. Men produce sperm, which is a type of sex cell (or "gamete") and women produce eggs, which are also a type of sex cell (or "gamete").
Answer:
(3a+2)/a(a+2)
Explanation:
(1/a)+(2/(a+2)
we cannot add any unlike fractions simply,we have to make it's denominator equal to add
you can do it by simply multiplication or by taking lcm of the the denominator!
here , it's 'a' and 'a+2'
now we got a modified denominator a(a+2), to make it fair to each term we have to multiply the extra multiplicand to numerator too
in case of 1/a, denominator becomes a(a+2) ,so we have to modify numerator also by multiplying the extra (a+2) to numerator also ,now 1/a becomes (a+2)/a(a+2)
---- similarly other term={2/(a+2)}can be modified as 2a/a(a+2)
now both denominator are equal , now new can add it simply by it's numerator
i.e, (a+2)/a(a+2) + 2a/a(a+2)
= (3a+2)/a(a+2)
it's from basic of fraction's addition!
