(01.03 MC) Scientists have found that all living things. from bacteria to humans, rely on genetic
codes to direct the functions of their cells. These genetic codes are contained in
strings of nucleotides and have very similar structures. Which hypothesis for the
origin of life on Earth is supported by this evidence?
Nucleotides and proteins that form the basis of life were originally carried to
Earth from outer space by comets and meteorites.
O Self-replicating RNA in the early Earth's oceans served as the basis for the DNA
in cells today.
Greenhouse gases in the atmosphere produced amino acids that are used in cells
today.
Photosynthesizing bacteria provided oxygen that formed ozone which protected
DNA from mutating into different forms.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
