The 4 factors affect evolution, according to Darwin’s Origin
of Species are;
Variation
Heritability
Competition
Differential survival
Variation ensures that
there is variability of population traits
on which selection pressures will apply.
Heritability means that the traits must be able to be passed down to offsprings through gametes.
Competition occurs when the individuals in the population compete for limited resources
Differential survival
occurs due to competition for resources
and other selection pressures. This result
to the survival of the strongest and weeding
out of the weak from the population.
The answer is true. During translation of mRNA, the nucleotides are read by the translation unit (ribosome and trna) in sequences of three (3). These sequences are referred to as codons. Codons code for amino acids. Some codons are start of stop codons meaning they initiate or terminate translation. Additionally, more that one codon could code for one amino acid.
Answer:
Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection.Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. ... This subducted material sinks through the Earth's interior.
