Answer:
Dichotomous keys typically stress identifying species by their scientific name, as each individual species has a unique scientific name. Dichotomous are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms.
Explanation:
Answer:
d) sedimentary, metamorphic and igneous
<span>Base on the data in the graph, the event that would most likely happen if the paramecium were placed in distilled water is that "The contractions would increase." This is the result of a hypertonic solution. </span>The net movement of water in an aqueous solution is form the higher
water concentration to a lower water concentration. A
hypertonic solution has higher solute in the cell than the outside. The
movement is from the cell to the outside and so the cell will shrink.
Answer:
b. the bottleneck effect.
Explanation:
The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.
The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.
The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.
Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
Earth's orbit is the path in which the Earth travels around the Sun. The average distance between the Earth and the Sun is 149.60 million kilometers (92.96 million miles) and a complete orbit occurs every 365.256 days (1 sidereal year), during which time Earth travels 940 million kilometers (584 million miles
