I choose letter "C. increased" for this item. The increase of carbon dioxide in the atmosphere is caused by many factors but is primarily due to emissions from industrial plants, great increase in number of vehicles, and many other activities.

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.

Seaweed belongs to which of Earth’s spheres?<br> atmosphere
LUCKY_DIMON [66]

Answer:

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

So I would say seaweed belongs in the hydrosphere.

I hope it helps.

What is more permeable monounsaturated phospholipids or saturated phospholipids?
geniusboy [140]

Answer: The second factor that leads to fluidity is the nature of the phospholipids themselves. In their saturated form, the fatty acids in phospholipid tails are saturated with bound hydrogen atoms; there are no double bonds between adjacent carbon atoms. This results in tails that are relatively straight
