Briefly explain how genes affecting a polygenic characteristic are located with the use of QTL mapping.
Answers
Answer:
QTLs can be identified by using molecular markers associated with the variation of the trait
Explanation:
A Qualitative Trait Locus (QTL) is a chromosomal region correlated with the variation of a quantitative trait, i.e., a phenotypic trait controlled by many genes. QTL mapping refers to the identification of QTLs associated with a particular trait. In QTL mapping, molecular markers (i.e., small and identifiable DNA fragments) are used to develop genetic linkage maps which are further used to discover QTLs. This technique (QTL mapping) consists of evaluating the phenotypic segregation of the trait in the progeny by statistically correlating phenotypes with patterns of genetic segregation (segregation of the molecular markers).

Explain why emerging efforts are focused on reducing health risks from exposure to chemicals rather than completely
eliminating those risks.
Answers
Answer:
Working with all chemicals carries some level of health risk, and modern society is dependent upon thousands of chemicals to maintain our standard of living. Therefore it is not reasonable to eliminate all chemical related health risks because that would require we stop using chemicals like cleaning supplies, gasoline, and fertilizers. The more practical approach is to minimize and manage the health risks associated with chemical exposure.

What happens when a nerve impulse reaches the end of a neuron?
A. Neurotransmitters are released and bind to receptors on the next
neuron, causing potassium ions to move into the neuron.
B. Potassium ions are pumped into the synapse, creating an action
potential at the next neuron.
C. The nerve impulse stops.
D. Potassium ions cause the synapse to close, allowing the impulse
to pass directly to the next neuron.
Answers
Answer:
A, the answer is A.
Explanation:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. The binding allows the nerve impulse to travel through the receiving neuron.
Hope this helps! :D

Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).
Answers
Answer:
Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:

c. have changed the behavior of elk.
Explanation:
Wolves were reintroduced into Yellowstone Park in 1995. Prior to this time, they were a major predator in the park. Their reintroduction after a decade resulted in a change in the behavior of the Elk which now had a large population in the park and appeared in large herds.
The Elk's behavior has also changed as they do not move into farther thickets so as not to be attacked by wolves. Also, they no longer move to open fields where they grazed as herds to avoid being preyed upon by lions. Vegetation is now restored due to this change in behavior of the Elk.
