[#266] The most suitable temperature for separation of cream by centrifugal cream separator is
Correct Answer

(A) 40°C

Explanation

Solution: The most suitable temperature for the separation of cream by centrifugal cream separator is 40°C. By regulating the cream discharge opening by adjusting the cream screw, we can maintain the desired fat % in the cream. The ideal temperature for separation is 35° - 45°C. The purpose of the skimming process is to separate the raw milk into skim milk and cream. The product temperature should normally be kept to ensure optimal skimming efficiency.

[#267] Spore forming bacteria
Correct Answer

(C) Both A and B

Explanation

Solution: Spore-forming bacteria Bacillus and Clostridium. Spore-forming bacteria include Bacillus (aerobic) and Clostridium (anaerobic) species. The spores of these species are dormant bodies that carry all the genetic material as is found in the vegetative form but do not have an active metabolism. These bacilli are ubiquitous, and because they form spores, they can survive in the environment for many years.

[#268] Ovum produce
Correct Answer

(A) Fertilizin

Explanation

Solution: Ovum produces Fertilizin. ovum is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). A chemical substance called fertilizin attracts the male epitokes and stimulates the shedding of sperm. It is secreted by a mature egg also known as the ovum.

[#269] The buffalo commonly known as an
Correct Answer

(B) Asian animal

Explanation

Solution: The buffalo is commonly known as an Asian animal. The buffalo (Bubalus bubalis), also called the Asian water buffalo, is a large bovid originating in the Indian subcontinent and Southeast Asia. The skin of the river buffalo is black, but some specimens may have dark, slate-coloured skin. Water availability for buffalo is important in hot climates since they need wallows, rivers, or splashing water to assist in thermoregulation.

[#270] Substance responsible for increase penetration of Lyssa virus
Correct Answer

(A) Hyaluronidase

Explanation

Solution: Substance responsible for increased penetration of Lyssa virus is Hyaluronidase. Hyaluronidase is an enzyme that breaks down a substance in the body called hyaluronic acid. Hyaluronic acid is found throughout the body in connective tissue, skin, and fluids in the joints and inside the eye. Lyssavirus is a genus of RNA viruses in the family Rhabdoviridae that are enveloped, with bullet-shaped geometries. These virions are about 75 nm wide and 180 nm long. Lyssavirions have helical symmetry, so their infectious particles are approximately cylindrical. This is typical of plant-infecting viruses.
