Question 1
1 / -0

Which of these build the hive, collect nectar and pollen, clean the cells and protect the hive?

A
Queen bee

B
Worker bee

C
Drone

D
Male bee

Solution

The worker bees are the smaller, sterile female bees. They are called as nurse or housekeepers. They are involved in taking care of the hives and the young ones. They help in building the hives and protect the hives from the other animals. They help in pollination, collect the nectar and transfer the pollens between the flowers.
Thus, the correct answer is option B.
Question 2
1 / -0

Given below are the characteristics of an organism 'X'.
(i) Builds the hives.
(ii) Collects nectar and pollen.
(iii) Cleans the cells and protects the hive.
Which of the following is 'X'?

A
Queen Bee

B
Worker Bee

C
Drone

D
Male Bee

Solution

Honey bees are divided into three castes queen for reproduction, worker sterile female and drones male. The given characteristics are related to worker bee. Worker honey bee does all the activities except mating. they collect nectars and helps in pollination, construct, cleans and protects the hives.
Question 3
1 / -0

Which of the following is an important objective of biotechnology in the field of agriculture?

A
To produce disease resistant varieties of plants

B
To increase the nitrogen content

C
To decrease the seed number

D
To increase the plant weight

Solution

The development and use of biotechnology in agricultural practice to improve the yielding capacity is the agricultural biotechnology. The main objective of biotechnology in the field of agriculture is to improve the quality of seeds, to produce the disease resistance varieties, increase the yielding capacity etc. Thus, the correct answer is option A.
Question 4
1 / -0

A colony of honey bees Affected by CCD (note the small number of adult workers relative to a large amount of unhatched brood that forms the waxy cells in the hive frame. Frames 1 and 3 are most greatly affected.
In 2007, a significant proportion of American beekeepers complained of unusually large losses of bee populations from their overwintering levels in late 2006. Loss of some colonies (approximately 10%) in early spring is normal and occurs every year. The problem was also reported by beekeepers in Europe, and researchers do not understand the specific causes of these losses.
At present, the syndrome is mysterious given that the main symptom is simply a low number of adult bees in the hive. There are no dead bodies and despite the fact that the affected colonies do co-exist with many disease organisms, no external signs of disease, pests or parasites seem to exist.
Going forward, which of the following observations and associated questions might not reasonably lead to testable scientific investigations into CCDs root cause(s)?

A
Beekeepers in 22 states, including Hawaii, reported larger than average population declines. Were the losses in 2007 within normal range?

B
The parasitic mite, Varroa destructor, infests brood (larvae) cells and lives on and is carried by adult bees. If heavy mite infections are visible to professional beekeepers, could a link be made between CCD and Varroa parasitism?

C
A certain protozoan, Nosema apis, infests the guts of adult bees and, when present in high numbers, causes dysentery (associated with diarrhea and fluid loss). If colonies, yet to experience CCD, feature Nosema infestation and are treated to eradicate the parasite, will this prevent CCD?

D
It has been noted that a variety of viruses affect adult bees. Under conditions of stress viral populations can increase and cause CCD symptoms (e.g. paralysis, trembling and an inability to fly) in adult bees. Typically, stressful triggers include poor nutrition, bad weather or parasitism. If a virus is present with a larger number of stressors (i.e. poor nutrition and hosting two parasites), will the symptoms of CCD be greater than infection by virus alone?

Solution

A- Option B, C & D give probable reasons to understand the specific causes of the huge losses of bee populations. They lead to testable scientific investigations into CCDs root cause(s). While, option A further puts forward a question mentioning whether the loss in 2007 was within normal range but it fails to give any reasoning regarding the CCDs root cause(s). Hence, Option A, does not lead to testable scientific investigations into CCDs root cause(s).
Question 5
1 / -0

Biofortification mainly involves

A
Selective breeding

B
Electroporation

C
Microinjection

D
All of the above
Solution
- Biofortification is the method in which the food is added or supplemented with the required nutrients.
- It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content.
- This can be done either through selective breeding or genetic modifications.
- The genetic modifications can be performed by transfer of the gene through microinjection and electroporation methods. This method is employed to improve public health.
Thus, the correct answer is option D.
Question 6
1 / -0

Biofortification mainly involves _________.

A
Increase in height

B
Increase in flowering

C
Increase in nutritional value of plant

D
All of the above
Solution
- Biofortification is the method by which the food is added or supplemented with the required nutrients.
- It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content.
- This can be done either through selective breeding or genetic modifications.
- This method is employed to improve public health.
- This process can be used for the production of staple crops with higher levels of essential nutrients.
Thus, the correct answer is option C.
Question 7
1 / -0

Which of the following is a major advantage of biofortification?

A
It is applicable for staple crops.

B
It aims to improve nutritional quality of food.

C
It produces higher yield in environmental friendly manner.

D
All of the above.
Solution
- Biofortification is the method in which the food is added or supplemented with the required nutrients.
- This process can be used for the production of the staple crops with higher levels of essential nutrients like rice produces beta-carotene and wheat produce zinc.
- Breeding of conventional crops with improved nutritional quality plants is undertaken to improve the content of proteins, oil, vitamins, minerals, and micronutrients in crops.
- The plants are produced by breeding to produce a high yield with more nutritional content.
- This serves as an environmentally friendly technique to overcome the problem of deficiency.
Thus, the correct answer is option D.
Question 8
1 / -0

The best way to improve nutritional deficiency in rural areas is

A
Biofortification of staple crops

B
Biofortification of ornamental plants

C
Biofortification of vegetative plant

D
None of the above

Solution

Biofortification is the method in which the food is added or supplemented with the required nutrients. This process can be used for the production of the staple crops with higher levels of essential nutrients. This can be done either through selective breeding or genetic modifications. The staple crops like wheat are fortified with zinc and the golden rice, rice is fortified to produce beta-carotene. The rural areas generally feed on the staple crops and suffer from nutrient deficiency. The consumption of this fortified crops will prevent the deficiency disorders and improve the health of the people in the rural areas.
Thus, the correct answer is option A.
Question 9
1 / -0

Hidden hunger can be cured by

A
Biomagnification

B
Biofortification

C
Bioremediation

D
Biosensors
Solution
- Biofortification is the method in which the food is added or supplemented with the required nutrients.
- It is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content.
- Hidden hunger is the condition in which the people suffer from nutrients deficiency due to less intake of nutrients in the diet. This condition can be prevented or treated using the application of fortified foods.
- The food which is selected for fortification is the food which can be made available even in the rural areas.
Thus, the correct answer is option B.
Question 10
1 / -0

Golden rice which is an example of biofortification was used to introduce which of the following vitamins?

A
Vitamin D

B
Vitamin A

C
Vitamin C

D
Vitamin E
Solution
- Biofortification is the process by which the nutritional quality of food crops is improved.
- Golden rice is a variety of rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of rice.
- Vitamin A deficiency is considered to be one of the most harmful forms of deficiency .
- Thus, Golden rice project was intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A.
So, the correct answer is 'Vitamin A'
