Match the theorist with the correct statement. 1.big bang "the universe will eventually contract in a big crunch." 2.inflation "the universe rapidly expanded within milliseconds after the big bang." 3.oscillating universe "the universe is the same and always will be the same." 4.steady state "the universe popped into existence from a single, dense, hot, chaotic singularity."

The matches are:

Big bang ==> "The universe popped into existence from a single, dense, hot, chaotic singularity."

This theory tells that the story of the Universe as we know it began about 13.7 billion years ago by a very dense and very hot phase

Inflation ==> "The universe rapidly expanded within milliseconds after the big bang."

Oscillating universe ==> "The universe will eventually contract in a big crunch."

The theory of the oscillating universe or cyclic motif is a theory, first proposed by Aleksandr Aleksandrovič Fridman based on Albert Einstein's general relativity, according to which the 'universe He will develop to a certain point, then retract into a state similar to that of Big Bang.

Steady state ==> "The universe is the same and always will be the same."

image result for describe the various types of gene mutationsghr.nlm.nih.gov

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
