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.
A salt is an ionic compound which needs a positive charge ion and a negative ion charge to form a salt.This means that the pair of element should be a metal and non-metal.This is simply because metal atoms tend to lose negative charge electrons and form positive ions while non-metals tend to receive the electrons from the metal atom to form negative charge ions.So answer is Cl and Li.
Answer:
Associative learning may be defined as a type of learning in which the new response gets easily associated with the stimulus. Except habituation learning all simple learning procedure are included in this learning.
In the associative learning, reactions of an individual are based on there spank. George learns to cry on being spanked this is because this stimulus of sister cries gives response. Crying do not show any effect on ken because he does not know about his sister crying.
Answer:
the answer is b.
Explanation:
prokaryotes don't have organelles, like eukaryotes do.
Synthesis of protein is the building up of protein molecule while the breakdown of protein is the degradation of the protein molecule.
<h3>What is protein?</h3>
Protein is one of the biological molecules that present in living organisms and contain it's building blocks known as amino acids.
The synthesis of protein is the process used by living organism to produce proteins from amino acids (that is the building block).
The breakdown of protein is the degradation of protein molecule which is also called catabolism.
Therefore, the difference between protein synthesis and breakdown is that synthesis of protein is the building up of protein molecule while the breakdown of protein is the degradation of the protein molecule.
