The soil samples are stored in plastic film containers, Thus, option "B" is correct.
Soil is the thin layer of material surrounding the earth's texture and is constructed from the weathering of gravel.
It is created up, especially of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.
Thus, option "B" is correct.

Yes, species pairs show more than one barrier to reproduction. Examples include damselflies with incompatible reproductive organs, species of flowers attracting different pollinators, bird species with different mating dances, and species producing infertile offspring.
Yes, there are several instances where species pairs show more than one barrier to reproduction. These barriers can be prezygotic or postzygotic. Examples include damselfly males and females of different species that have differently shaped reproductive organs, thus creating a mechanical barrier. This means their body parts simply do not fit together and reproduction cannot occur.
Also, two species of flowers may attract different pollinators, creating a barrier known as habitat isolation, in which the species live in the same area but different habitats. Furthermore, bird species may display different mating dances. This is behavioral isolation where species differ in their mating rituals. There's also reduced hybrid fertility where two species of insects produce infertile offspring. The mechanisms of reproductive barriers in nature are complex and diverse in their operation.

1. mRNA (messenger RNA): it provides the template for protein synthesis during translation.
2. tRNA (transfer RNA): it brings amino acids and reads the genetic code during translation.
3. rRNA (ribosomal RNA): it plays a structural and catalytic role during translation.
B: a 5kg dining chair
C: a 75kg dining table
D: an 10kg end table
Answer: The correct option is C.
Explanation:
Inertia is a property of the matter by virtue of which it resists any change in its state of rest or motion. Inertia is directly related to the mass of the matter.More the mass more would be the inertia and harder would be for an object to change its state.
Thus the furniture which faces most difficulty in moving is 75 kg dinning table due to its greater mass. Therefore more force would be required to push the table. And hence it has greater inertia.
The answer is C) 75 kg dining table :)
