Answer:
<h2>They are classified on the basis of their cell wall composition and as well as by the reaction to the Gram stain test.
</h2>
Explanation:
Most bacteria are classified into two main categories
i) Gram positive bacteria and ,
ii) Gram negative bacteria.
They are classified on the basis of their cell wall composition and as well as by the reaction to the Gram stain test.
Gram positive bacteria's characteristics
ii) they have cell walls composed mostly of peptidoglycan.
i) stain purple after Gram staining.
Gram negative bacteria's characteristics.
i) they have cell wall only a thin layer of peptidoglycan and an outer membrane with a lipopolysaccharide component.
ii) stain red or pink after Gram staining.
The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.
<h3>What is Allelic frequency?</h3>
The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.
The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:
2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.
∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.
The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.
Therefore, it is well described above.

Answer:
The correct option is C. Spine is present on the posterior surface of the scapula
Explanation:
The scapula is a triangular bone that joins humerus with the clavicle.
The landmarks present on the posterior surface of the scapula are:
1. Spine: The spine of the scapula divides it into two parts.
2. Acromion: This is the landmark that connects with the clavicle.
3. infraspinous fossa: This landmark is present underneath the spine and the infraspinatus muscle is located here.
4. Supraspinous fossa: It is the landmark that is situated on top of the spine.
