According to <em>Newton's Second Law of Motion</em>, force is defined as mass times acceleration. If the same car is accelerated to <u>60 mph</u> compared to 30 mph, the force will be <u>greater</u>.
Answer:
We are getting taller because of improved nutrition and health.
Explanation:
Height, as a polygenic trait, is controlled by more than 2 genes in humans. Height as a trait in humans can be determined by the genetic code of an individual as well as the environmental conditions where such individual lives in. Environmental factors such as good and conducive environment, improved standard of living, and most especially nutrition and health.
The most reasonable cause why we seem quite taller than humans of 100 years ago is simply as a result of improved nutrition and health which was made possible by our advances in science and technology. Good standard of living and improved nutrition is responsible for we getting taller.
B. mass extinctions happen when populations crash due to overpopulation while background extinctions are more likely to result from disease.
Answer:
The equation of the photosynthesis becomes reverse in the cellular respiration. In both process the reactants and products are altered.
Photosynthesis is the light harvesting process. Here the plants use water, carbon dioxide, light as raw material to produce glucose, energy and oxygen. This process occurs in the chloroplast of the leaves. In this reaction the products are oxygen and glucose.
In cellular respiration, the byproduct of photosynthesis i.e. glucose is oxidised to release energy and carbon dioxide, along with the ATP molecules. This reaction is the reverse reaction of the photosynthesis.
In cellular respiration the product of the photosynthesis becomes becomes reactant.
The cellular respiration occurs in the cytoplasm of the cell and involves many steps to release energy. The various cellular respirations are glycolysis, kreb's cycle, electron transport chains, etc.
Answer:
Salt is a compound
Explanation:
A compound had fixed mass ratio of elements.
And the characteristics of the compound is different from its constituents. E.g taste of soap is different from its constituents like palm oil, soda, fragrance etc
Other compounds are water, caustic soda, limestone etc
