Answer:
it stresses secrecy in scientic investigations
Answer:
Genetic variation
Explanation:
Drift and natural selection are natural phenomena that occur when there exists genetic variation. In the first case (drift), the consequence will be the decrease in the genetic diversity, while natural selection will change the allele frequencies in order to favor adaptive genetic differentiation
Answer: b. Remains of formerly living things buried by sediments in regions with little oxygen.
Explanation:
Fossil fuels are underground geological fuel deposits which are formed from the decaying of organic materials (animals and plants) over hundreds of millions of years in the earth's crust, which furthur processed into coal, crude oil, heavy oils or natural gas by exposure to pressure and heat
Fossil fules are present only in sedimentary rocks under litte oxygen the provide temperatures and pressures that do not kill fossil remains, unlike most igneousand metamorphic rocks.
Hence, the correct option is b.
Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds. Covalent compounds have bonds where electrons are shared between atoms.
