Answer:

b. grasshopper effect

Explanation:

Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.

When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.

A scientist discovers a new organism that is related to clownfish. What can the scientist discover by using molecular clocks?
Margaret [11]

Answer;

C) the amount of time that the two species have been evolving apart

Explanation;

-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.

- The molecular clock hypothesis states that DNA and protein sequences evolve at a rate that is relatively constant over time and among different organisms. A direct consequence of this constancy is that the genetic difference between any two species is proportional to the time since these species last shared a common ancestor.

Why are scorpions florescent to black light? How might it help them survive?
givi [52]

Answer:

Well, something in the scorpions' exoskeleton causes them to glow. The fluorescence makes their bodies more sensitive to light, so it's easier to find a shady hiding spot to survive in.
