Answer:
1. Newton believed that gravity was a force.
3. The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Explanation:
Law of gravitation states that force is directly proportional to masses of objects and inversely proportional to the distance between from their center. Directly means if mass increases, force of attraction also increased while inversely means if distance decrease between objects, force of attraction is also increased. Gravity is measured in weight because weight ia a force which attracts things towards its center.
Answer:
<em>The correct option is A) make food.</em>
Explanation:
Photosynthesis can be described as a process by which organisms like plant and some algae make their own food. They use light energy from the sun to convert carbon dioxide and water into glucose and oxygen. Oxygen is the by- product of this reaction. Hence, option A is correct.
Other options are wrong because photosynthesis is not a process by which energy can be extracted from food or it is not a process by which excretion of waste occurs. Neither is it a process of reproduction.
Answer:
Population size of elk increased while the population of aspen tree declined.
Explanation:
As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
