Which of the following is a contributing reason behind emerging disease? a. The lack of evolution in hostsB. The overuse of antibioticsC. The absence of migration or travel in organismsD. The lack of evolution in pathogens

Answers

Answer 1

Answer: The correct answer should be B. The overuse of antibiotics. Since antibiotics as their name says kill biotics, that is, they fight against bacteria, they were used a lot and bacteria started developing resistance to them which is a common thing. Since it's difficult to find new types and the trials last long, new diseases are emerging faster than we can create medicine for them.

Which of the following is NOT a source of point-source pollution? a. trash dumping c. pesticide runoff b. sludge dumping d. oil spill

Answers

Answer: c. pesticide runoff

Explanation: A point source pollution is the pollution which is caused by the pollutants whose source of origin can be traced back and further pollution can be prevented. A non-point source pollution is the one which cannot be traced back to it's origin and hence, cannot be prevented from further pollution. Trash dumping, sludge dumping and oil spill are the examples of point source pollution. But pesticide runoff is the example of non-point source pollution. A surface runoff will wiped off the pesticides from their surface and discharge them to the water body the source of origin of these pesticides will remain undetermined.

For any given gene, what ultimately determines which dna strand serves as the template strand?

Answers

The answer is the base sequence of gene's promoter.

DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.

The mineral crystals in obsidian are too small to see without a microscope. This is because it _____.

Answers

The mineral crystals in obsidian are too small to see without a microscope. This is because the rock cools so rapidly from magma that crystals barely have time to form. Obsidian is a normally happening volcanic glass framed as an extrusive molten shake. It is delivered when felsic magma expelled from a well of lava cools quickly with negligible precious stone development.
