Nutrient pollution is the situation when due to the excess nutrient levels, excessive amounts of algae grow - so the correct answer is c. excess fertilizer use.
Pouring motor oil down the drain also results in pollution, but in other kind of solution - not nutrient solution.
Answer:
Option A
Explanation:
Options
A. most populations were fixed for a single genotype, but genotypes varied among populations
B. average heterozygosity was declining steadily over time
C. individual populations were polymorphic for several loci and most populations were genetically similar to one another
D. all populations were fixed for the same allele at each locus studied
Solution
As per the study conducted by Templeton, it was found that human affect the biodiversity at all biological levels such as genetic, ecosystem, species etc. and behind genetic variation two important factors are genetic drift and gene flow.
Both the gene flow and genetic drift produce opposite results as genetic drift increase variation with in the species but decrease variation with in the local population and the opposite of this happens in gene flow.
Genetic drift has actually lead to speciation of collared lizards among themselves for a specific genotype
Hence, option A is correct
Answer:
D
Explanation:
Thermal energy is the energy that is generated and measured by heat.
Answer:
oxytocin
Explanation:
Oxytocin is a hormone naturally produced by our body to generate contractions of the uterus during labor and the release of milk during breastfeeding. It was synthesized in the laboratory and thus became a very useful medication that can help save lives if correctly indicated.
This hormone can also be used to initiate labor when it does not occur naturally, and can regulate contractions when they are not effective and it is diagnosed that labor is not progressing properly.
In addition, it can also be used to contract the uterus after childbirth or abortion when bleeding is very abundant, preventing bleeding that could lead to loss of the uterus and even death if not properly controlled.
They are representatives between the extinction events
