Answer 1

Explanation:

Bacteria are the largest group of unicellular microorganisms. The shapes of medically important bacteria are classified into-cocci, or spherical cells; bacilli, or cylindrical or rod shaped cells; and spiral or curved forms. The pathogenic or disease causing bacteria are usually gram negative, however, three gram-positive rods are known to cause food intoxications : Clostridium botulinum,C. perfringens,and Bacillus cereus

Some of the other most common bacteria causing food spoilage, infections and disease are Acinetobacter, Aeromonas, Escherichia, Proteus, Alcaligenes, Flavobacterium, Pseudomonas, Arcobacter, Salmonella, Lactococcus, Serratia, Campylobacter, Shigella, Citrobacter, Listeria, Staphylococcus, Micrococcus, Corynebacterium, Vibrio Enterobacter, Paenibacillus, Weissella, Enterococcus, Yersinia

Different strains of bacteria are also used in production of various food and dairy products. Strains of Streptococcus, Lactobacillus Bifidobacterium, Erwiniaetc. are used in the production of fermented food and dairy products. Streptococcus thermophilus and Lactobacillusbulgaricus are used to produce yogurt

Answer 2

Explanation:

1.Some of the microorganisms like bacteria and fungi play a variety of roles in the formation of household food.

For example, Lactobacillus, the bacteria involved in the formation of curd from the milk and yogurt is produced by the bacteria, Lactobacillus bulgaricus.

Saccharomyces cerevisiae is a type of yeast used for making bread in the household as well as food processing industry.

Microorganisms are also used to prepare some traditional drinks like Toddy.

In addition to these, most common food like dosa and idly are prepared from fermented rice by some bacteria.

2.In a colony, there are 10,000 to 60,000 bees! But all of them do not collect nectar- there is a strict division of labour. The queen bee and female bees lay thousands of eggs. Larvae that hatch are fed royal jelly and the duration that they are fed will decide their role as a worker or queen. The drone bees are male and their job is only to help in fertilizing the eggs laid by the queen, and the worker bees do the actual work of collecting nectar

importance of apiculture

Apiculture provides products such as honey and wax that are used commercially.

Honeybees are responsible for pollination and thus help in increasing the yield of the several plants.

Some recent researches have proven that honeybees venom comprises a mixture of proteins that has the capability of destroying the AIDS virus.
