NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus. Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams.

Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1. Mode of nutrition of explant before organogenesis is

•  Photosynthetic
•  Autotrophic
•   Heteromorphic
•   Heterotrophic

Solution
d) An explant is the excised piece of tissues or organs used for culture. An explant before organogenesis is heterotrophic which grows on a synthetic medium and sucrose is the most commonly used carbon source

Q2.The part of the grain in cereals, where much of the protein lies is the:

•  Aleurone
•  Endosperm
•  Pericarp
•  Embryo

Solution
A)

Q3.  Compared to a bull a bullock is docile because of:

•  Higher levels of cortisone
•  Lower levels of blood testosterone
•  Lower levels of adrenalin/noradrenalin in its blood
•  Higher levels of thyroxina

Solution
B)

Q4. An explant is

•  Dead plant
•  Part of the plant
•  Part of the plant used in tissue culture
•  Part of the plant that expresses a specific gene

Solution
c) The part of the plant taken for tissue culture is called explant

Q5.Which of the following is correctly matched?

•  Apiculture – Honey bee
•  Pisciculture – Silk moth
•  Sericulture – Fish
•  Aquaculture – Mosquitose

Solution
 (a) Apiculture is the rearing of bee or bee keeping for the production of honey and wax

Q6. Apiculture means

•  Rearing of honey bees
•  Rearing of silkworm
•  Rearing of lac
•  None of these

Solution
(a) The maintenance of hives of honey bees for the production of honey is termed bee keeping or apiculture. Bee-keeping is practiced in any area where there is availability of sufficient bee pasture of some wild shrubs, fruit orchards and cultivated crops

Q7.What will you conclude, when a cow is crossed to a bull and female progeny is yielding more milk than its mother?

•  More number of genes for high yielding milk are inherited, only from the female parent
•  More number of genes for high yielding milk are inherited only, from the male parent
•  More number of genes for high yielding milk are inherited only from both the parent
•  The progeny through mutation achieved more number of genes for high yielding milk

Solution
(c) In this case, more number of genes for high yielding milk are inherited from both the parents

Q8.Mule is produced from a cross between …A… and …B… Here A and B refers to

•  A-female horse; B-male donkey
•  A-male horse; B-female donkey
•  A-male horse; B-female horse
•  A-male donkey; B-female donkey

Solution
a) A-Female horse; B-Male donkey. Mating between male and female animals of two different species is called interspecific hybridization. The Mule is the best example of a successful cross between two different species, the female horse and the male donkey

Q9.Keeping beehives in crop field during flowering period increases

•  Honey and wax yield
•  Crop yield
•  Both (a) and (b)
•  Pollination in wheat

Solution
(c) Keeping beehives in crop fields during flowering period increases pollination efficiency and improves the yield, which is beneficial to both from the point of view of crop yield and honey yield

Q10. Which of the following is incorrect w.r.t SCP?

•  Quantitative and qualitatively superior proteins
•  Production involves utilization of organisms which has high rate of biomass production and growth
•  250 g Methylophilus methylotrophus can produce 20 tonnes of protein per day
•  :Can be obtained from both unicellular and multicellular organisms

Solution
(c) 250 g of a microorganism like Methylophilus methylotropus because of its high content of biomass production and growth, can be produce about 25 tonnes of protein
