Answer:
Serovars
Explanation:
Serovars refer to the different strains of a species of microbe that differ from each other with respect to the antigenic composition of a specific structure such as polysaccharides of the cell wall. Serovars are identified suing appropriate antiserum.
For example, the bacterial species <em>Streptococcus pneumoniae</em> have as many as 90 serovars that differ from each other with respect to antigens present in their capsules. These different serovars are identified by using antiserum for specific capsular types which in turn would induce capsular swelling.
Answer
A
Explanation
The parent rock is the soil horizon that contains big unweathered rocks. As the rocks weather, they form the soil horizon above (from the substratum, subsoil) until the topsoil is fine and deep enough to support plant vegetation.
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
