Q1. By 2005 , 1% of the world population in the age group 15-49 was affected by
Answer : Option C
Explaination / Solution:
HIV is a virus that attacks the human immune system and makes it susceptible to infections and diseases. Preventive measures can be taken to reduce the spread of AIDS.
Q2. Following are the types of frequency distribution except
Answer : Option D
Explaination / Solution:
The repetition of number is a data set is termed as frequency of that particular number or the variable in which that number is assigned. The frequencies of variables in a data are to be listed in a table. This table is known as frequency distribution table and the list is referred as frequency distribution.
There are many types of frequency distributions
- Grouped frequency distribution
- Ungrouped frequency distribution
- Cumulative frequency distribution
- Relative frequency distribution
- Relative cumulative frequency distribution
Q3. Policy of the government with respect to taxes and with respect to its own expenditure on running the administration of the country is known ass
Answer : Option D
Explaination / Solution:
No Explaination.
Q4. If the position- time graph is a straight line
Answer : Option D
Explaination / Solution:
The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object.
If the velocity is constant, then the slope is constant (i.e., a straight line).
Q5. Microwaves have a frequency of about
Answer : Option C
Explaination / Solution:
No Explaination.
Q6. If y(x, t) = a sin (kx + ωt + φ ) represents a wave function then ‘φ’ is
Answer : Option D
Explaination / Solution:
In the equation
y(x, t) = a sin (kx + t + )
The term represents initial phase or epoch
Hence the term is initial phase
Q7. In Mirabilis jalapa when two F1 pink flowered plants were crossed with each other, the F2 generation produced 40 red, 80 pink and 40 white flowering plants. This a case of
Answer : Option D
Explaination / Solution:
F1pink flowered plants are heterozygous. When selfing is done the genotype and phenotype develops as 1:2:1 as 40 red, 80 pink and 40 white flowering plants.
Q8. During cellular respiration, pyruvic acid is reduced to lactic acid in the presence of
Answer : Option C
Explaination / Solution:
Lactate dehydrogenase: (LDH) An enzyme that catalyzes the conversion of lactate to pyruvate When oxygen is inadequate for cellular respiration.
This is an important step in energy production in cells. Many different types of cells in the body contain this enzyme. Some of the organs relatively rich in LDH are the heart, kidney, liver, and muscle.
Q9. Which of the following represent examples of extracellular fluids?
Answer : Option B
Explaination / Solution:
Tissue fluid( lymph) and blood plasma represents the extracellular fluids. Lymph flows in lymphatic vessels and plasma in arteries and veins along with RBC, WBC and platelets.
Q10. , CO and are isoelectronic molecules. Their respective bond order is :
Answer : Option D
Explaination / Solution:
Total number of electrons in N2 molecule is 7+ 7= 14.
As per the formula Bonded pair of electrons Nb:
Total 10 electrons.
Anti bond pairs of electrons Na: Total 4 electrons.
Bond Order (B.O.) =
Similarly bond order of CO And NO+ is 3
