What is the function of in Gill Fish?
(A) take in oxygen from the air
(B) absorb nutrients present in water
(C) absorb dissolved oxygen from water
(D) excrete waste into water
Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.
What is the different from the rest?
(A) Deforestation
(B) Desertification
(C) Erosion
(D) Conservation
Except tomato, all others are grown under the ground. Potato, onion, carrot are root vegetable. Whereas, Tomato is grown above ground. Hence, Tomato is the correct answer.
In which of the following processes, is bacteria not used?
(A) Formation of curd
(B) Baking of bread
(C) Fermentation of Sugarcane juice
(D) Nitrogen fixation
Baking soda and baking powder help in baking bread. The microbe responsible for baking bread is a fungus named Saccharomyces cerevisiae for this reason it is also called baker's yeast. Hence, from the above-mentioned points, it becomes clear that bacteria are not used in the baking of bread.
In which part of the male reproductive system is the main genetic material found?

(B) in the ureter
(C) in sperm
(D) in the testicles
The sperm. The sperm is the male reproductive cell. Its role is to fertilise an egg. It contains the man's genetic material.
Which hormone causes milk to be released from the breast during lactation?

(A) Fetus
(B) Endosperm
(C) Zygote
(D) Egg
During sexual reproduction, two haploid gametes combine into one diploid cell known as a zygote in a process called fertilization. The nuclei from the gametes fuse, and each gamete contributes half of the genetic material of the zygote.

(A) 23
(B) 46
(C) 48
