Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.
The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.
The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.
Taxonomy is a classification study or organisms according to different characteristics. According to taxonomic studies, the order primates is composed of 16 families, 72 genera, and 240 species. Option D.
<h3>What is taxonomy?</h3>
Taxonomy is the study of different organisms and their classification into categories.
Classification is done according to their morphological and molecular characteristics and their evolutionary relationships.
A binomial name is assigned to each organism.
<h3>Which are the categories into which organisms are classified?</h3>
- Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.
- Kingdom: Includes different phyla closely related. The bacteria domain includes the Eubacteria kingdom. The archaea domain includes the archaebacteria kingdom. Finally, the eukarya domain is divided into four kingdoms: Protist, Fungi, Plantae, and Animalia.
- Phylum: Includes different classes closely related.
- Class: Includes different orders closely relates.
- Order: Includes different families closely related
- Family: Includes different genera closely relates
- Genus: Includes many species.
In the case of the order primates, we can find 16 families, 72 genera, and 240 species.
The correct option is D.

Answer:
Explanation:
Both parents have black color and normal vision but some of their progenies show brown color and some shows PRA, this reveals the brown coat color and PRA are recessive traits and both parents are heterozygous. The progenies include black normal vision, brown normal vision and black, PRA, that is the alleles for these genes separate independently of each other.
Let us denote the alleles as B-black, b-brown and P-normal vision, p-PRA, then the genotype of the heterozygous parent is BbPp, alleles separate independently of each other so the possible gametes are alleles for the color and vision segregate independently during gamete formation.
Thus, option C is correct.
Answer:
Explanation:
Flavoprotein which are involved in electron transfer are located in inner mitochondrial membrane and accepts the electrons from primary dehydrogenases and transfer to electron transferring flavoprotein dehydrogenase which finally transfer them to coenzyme Q in a normal mechanism.
So if flavoprotein transfers the electrons directly to final electron acceptor it would produce a highly potent oxygen radical "hydrogen peroxide". Apart from this the other effect would be;
- The less protons would be pumped to intermembrane space of mitochondria and ultimately the production of ATP would be decreased.
- The energy of electrons would be lost in heat as it is not utilized for the production of ATP so there would be more heat production.
