The General Science Quiz! MCQ Trivia

Explanation
Sexual reproduction involves the fusion of two gametes, typically a sperm and an egg, to form a new individual. This process can be divided into three distinct stages: pre-fertilization, fertilization, and post-fertilization. Pre-fertilization includes events such as gamete production and mating, while fertilization involves the fusion of gametes to form a zygote. Post-fertilization encompasses the development of the zygote into an embryo and eventually into a fully formed organism. Therefore, sexual reproduction can be categorized into three stages.

Explanation
Fungi are not plants, but they are often classified in the same kingdom due to their similarities in structure and lifestyle. However, one key difference between fungi and plants is that fungi lack chlorophyll. Chlorophyll is a pigment found in plants that allows them to photosynthesize and convert sunlight into energy. Since fungi do not have chlorophyll, they cannot produce their own food through photosynthesis like plants do. Instead, fungi obtain nutrients by breaking down organic matter in their environment.

Explanation
Measles is an air-borne disease because it is caused by the measles virus, which is highly contagious and spreads through respiratory droplets when an infected person coughs or sneezes. These droplets can remain in the air for a while and can be inhaled by others, leading to the transmission of the disease. Measles is known for its ability to spread rapidly in crowded places and is a significant public health concern.

Explanation
The liver produces the fluid known as bile. Bile is a greenish-yellow fluid that aids in the digestion and absorption of fats in the small intestine. It is produced by the liver cells and then stored in the gall bladder until it is needed for digestion. Bile contains bile salts, cholesterol, bilirubin, and other substances that help break down fats into smaller molecules, making them easier to digest and absorb.

Explanation
SARS, or Severe Acute Respiratory Syndrome, is the coronavirus that kills humans. It emerged in 2002 and caused a global outbreak, resulting in severe respiratory illness and a high mortality rate. SARS is transmitted through close contact with infected individuals and respiratory droplets. It is important to note that while SARS is a coronavirus that can be deadly, there are other coronaviruses, such as the one causing COVID-19, that also pose a significant threat to human health.

Explanation
HCl, or hydrochloric acid, is the correct answer. It is secreted in the stomach and plays a crucial role in the digestive process by breaking down food and killing bacteria. H2SO4, HNO3, and H2CO3 are not acids that are secreted in the stomach.

Explanation
Kerosene is an example of a form of matter that has no fixed shape but has a fixed volume. Kerosene is a liquid and, like other liquids, it can take the shape of its container but it does not have a definite shape of its own. However, it does have a fixed volume, meaning that it occupies a specific amount of space regardless of its shape.

Explanation
Pisciculture refers to the management and production of fish. It involves activities such as breeding, rearing, and harvesting of fish in controlled environments like ponds, tanks, or cages. This term specifically focuses on the cultivation of fish for commercial purposes, including food production and stocking for recreational fishing. Apiculture refers to the management of bees and beekeeping, sericulture refers to the production of silk from silkworms, and aquaculture is a broader term that encompasses the farming of aquatic organisms including fish, crustaceans, and mollusks.

Explanation
Apiculture is the practice of beekeeping and the cultivation of bees for the production of honey and other bee products. Pasturage, which refers to the grazing of animals on natural or cultivated land, is not directly related to apiculture as bees do not graze on land. Cattle, fishery, and sericulture are all related to animal husbandry or the cultivation of specific animals for various purposes, but they are not directly related to apiculture. Therefore, the correct answer is apiculture.

Explanation
The other name for Apis cerana indica is Indian bee.
