In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
Q4. The first transgenic cow was
Answer : Option C
Explaination / Solution:

This transgenic milk is a more nutritionally balanced product than natural bovine milk and could be given to babies or the elderly with special nutritional or digestive needs.Rosie’s milk contains the human gene alpha-lactalbumin.
Q5. In Daniell cell, direction of current is
Answer : Option D
Explaination / Solution:
Current is taken at the direction in which positive charge is flowing, but electrons are negatively charged. So, the direction of current and the direction of electron flow is opposite.

Q8. when two capacitors are put in series, the equivalent capacitance is
Answer : Option C
Explaination / Solution:
When two capacitors C1 and C2 are connected in series, the reciprocal of the equivalent capacitance in series is equal to the sum of the reciprocals of the two individual capacitances.
It has value lesser than the least value of capacitance.
It has value lesser than the least value of capacitance.
