Answer:
D. can be your answer
Explanation:
because she is testing and finding differnt results which can help her find the algae levels in a local stream.
The independent (or manipulated)variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (orresponding) variable is the one that is observed and likely changes in response to the independentvariable.
Answer:
number of different species
Explanation:
The diversity of a species is the number of different species in a given community (dataset). Meanings of species diversity may include species richness, taxonomic or phylogenetic diversity, and/or species evenness.
Answer:
Option B, No
Explanation:
Complete question is as follows -
You have spent time working with a population of beetles. Sexually mature males range in size from 2-6 cm in length. You realize that the females only mate with males that measure less than 3 cm long. If you measured allele frequencies at a single gene (locus) that contributes to overall length, would you expect this population to be in H-W equilibrium from one generation to the next?
Select one:
a. Yes
b. No
Solution -
No, because Hardy Weinberg’s equilibrium theory is not applicable in practical scenario as it assumes that H-W equilibrium persists from one generation to the other only when these is no disturbing factor . These disturbing factors include – natural selection, non-random mating, genetic drift, gene flow and mutations. Since this theory works only in an idealized state where no such disturbances occur, it is very difficult to say that the beetle population can remain in H-W equilibrium. Also the females in the beetle population are selecting the males for mating thereby exhibiting sexual selection. Hence, H-W equilibrium will not be applicable.
Hence, option B
<span>According to the Centers for Disease Control and Prevention (CDC), diseases caused by smoking kill more than 480,000 people in the U.S. each year. In fact, smoking is directly responsible for almost 90% of lung cancer and COPD deaths. Even with antismoking campaigns and health warnings, many people continue to smoke or start to smoke every year. About 8% of kids under the age of 18 years are current tobacco users.</span>
