What were the effects of the increase in White Collar Jobs?

scoundrel [369]

White-collar workers were introduced into the realm of modern social science at the end of the nineteenth century. The starting point was twofold: (1) the notion of a growing number of occupations, employments, and functions that shared many traits of the working class while at the same time differing in important aspects from manual workers as well as from the higher social strata; and (2) the exceptional rapid growth of these categories in the decades around the turn of the century, which even outdid that of the manual workers.

How did Mendel make crosses with his plants?A., He planted the seeds of each type together, and they grew into a single plant. B

PilotLPTM [1.2K]

Answer:

The correct answer will be option-C.

Explanation:

Gregor Mendel is known for his experiments performed on the pea plants on the basis of which he was able to predict the principles of inheritance. He used seven different characters to understand the inheritance pattern of the traits in generations.

He performed monohybrid (single) and dihybrid (two) crosses by growing the plants from the seeds and performing cross-fertilization and self-fertilization. He performed self- fertilization by emasculation and cross-fertilization by shedding the pollen of another plant over ovules of another plant.

Thus, Option-C is the correct answer.
