Answer:
Let's start by using the definition of acceleration. Acceleration is defined as the change in velocity over the change in time. In equation, that would be Δvelocity/Δtime. Based on the axes of the given graph, it shows the trend of position over time. So, the slope of the line and the curve shows the change of position over change of time, Δdistance/Δtime. In physics, this is the definition of speed or velocity. So, Maia is incorrect. Both curves show the speed or velocity of the object, and not acceleration. If the graph used a y-axis of velocity instead of position, then only at that instance, would be Maia be correct.
The difference between the two is, the straight line shows constant velocity while the curve line shows changing velocity.

Answer:
Explanation:
A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. ... The first change of phase is melting, during which the temperature stays the same while water melts. The second change of phase is boiling, as the temperature stays the same during the transition to gas.
Answer : The correct option is A.
Explanation :
The given chemical reaction is,
In the reaction, Reactants are present on the left side of the arrow and products are present on the right side of the arrow.
Reactants are those which takes part in and undergoes change during the reaction.
Products are those which are formed during the reaction.
In the given reaction, zinc react with hydrochloric acid to form zinc chloride and hydrogen gas.
Therefore, the reactants are zinc and hydrochloric acid.
Answer:
more genetic variation within a population usually enables more phenotypic variation.
Explanation:
Because natural selection acts directly only on phenotypes, Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
