Answer:
Scientist 1
Explanation:
<em>The conclusion of scientists 1 is valid.</em>
Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>
Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.
<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>

Answer:
To maintain this balance, the Hardy-Weinberg Equilibrium Principle states that a population should meet five main assumptions. There should be random mating, large population size, no mutation, no selection on the gene in question, and no gene flow in or out of the population.
Explanation:
The pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.
<h3>What is a true autotroph?</h3>
A true autotroph is an organism that produces biomass by a chemical process called photosynthesis.
This type of autotroph generates biomass by means of photosynthetic cycles of production.
In conclusion, the pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.
