The answer is the first one.
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.
Answer:
- an increase in supply
Explanation:
The interaction between the quantity demanded and the quantity supplied determines the price and the equilibrium quantity in a market economy. This is due to the rationality criteria of the economic agents (consumers will buy more quantities at the lowest possible price) and the law of supply and demand, according to which the excess / lack of products causes price decrease / increase and also an increase / decrease in quantity demanded. Thus, in order for the equilibrium price to decrease and the equilibrium quantity to increase, there must be an increase in supply, as there will be more products on the market, which will cause the price to fall. After the price drops, consumers will demand more. In this way, new price and quantity balance parameters will be determined.
