Answer:
Hydrogen
Explanation:
Elements that have low ionization energies tend to have low electronegativities. The nuclei of these atoms don't exert a strong pull on electrons. Similarly, elements that have high ionization energies tend to have high electronegativity values. The atomic nucleus exerts a strong pull on electrons.
Answer:
A) Phanerozoic
Explanation:
In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.
The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.
The Phanerozoic eon represents the time scale during which first visible life evolved and began around 542 million years ago and is present until today. The insects belong to the arthropod group which evolved during a smaller time scale called Devonian period.
Since the insects evolved around 479 million years ago which falls under the Phanerozoic eon, therefore, phanerozoic is the correct answer.
Thus, Option-A is correct.
Answer:
They are solid at room temperature. They include a carbon single bond.
Explanation:
Look at this image- hope it helps. Because of the fact that they are not bent, they are packed tightly and solid, not liquid.
The right option is OTEC
Ocean Thermal Energy Conversion (OTEC)
uses the temperature difference between deep cool ocean water and warm tropical
surface waters to produce electricity. Quantities of cold water that can be
used for air conditioning is produced as a by-product.
