Answer:
D
Explanation:
Mendeleev periodic table predicted the properties of undiscovered element like the eka-aluminium.
The correct answer is - b. If available resources decrease, then competition will increase.
All living organisms in an ecosystem are specialized in accordance to the living conditions and the food sources available. If a given ecosystem experiences prolonged drought, than the resources will decrease. With a decrease in resources, the living organisms will find themselves in a situation of scarcity. That will lead to a much increased competition, with both organisms of different species, and members of the same species. That will most likely lead to a situation where only the fittest will survive, while the weaker members of the species will probably die in that period of prolonged drought as they will not be able to get the resources they need to survive.

Liquid and Gas are the phases of matter that demonstrate fluidity.
Explanation:
The phenomenon of easy flow or easy transfer or movement of particles is termed as fluidity. As it is known that matters are basically classified into three types or phases. They are solid, liquid and gases. The solid particles are tightly bonded. In other words, high energy is required to move the atoms in the solid material. But in liquid the atoms are slightly loosely bonded. So they are flow easily. With only the viscous tendency hindering its flow, the liquid phased materials can be termed as fluid. Similarly, the easiest travelling particles are gas particles and so they also have fluidity and they are also termed as fluid. So the phases which are termed under fluid criteria demonstrating fluidity included liquid and gas phase
