What are the three major sources of oil pollution in the ocean?

The major sources of oil pollution in the oceans are:

  • Natural seeps: A large fraction of oil that is present in our oceans has seeped into them from the underground reservoirs of oil (the same ones that we drill into to obtain oil). This may account for almost 40% of all the oil in the oceans. In many locations, microbes present in the oceans can consume much of this oil, thereby keeping our oceans clean.

  • From automobiles: Automobiles generally drip some oil on the road. This oil is washed off by rainfall and from there it finds its way to the oceans.

  • Oil spills: These are a significant contributor to oil pollution. These may take place due to accidents in the ships carrying oils or at oil drilling rigs.

  • Disposal from luxury ships/cruise ships: A significant fraction of oil pollution is also caused by the disposal of oil by luxury ships or cruise ships into the ocean water.

Hope this helps.

What is the meaning of "juggling fiends" in Macbeth?

Macbeth is beginning to realize that the three witches have been deceiving him since he first encountered them. Like jugglers, they have kept changing their forecasts in order create confusion. This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a...

What are some tensions between men and women in Shakespeare's Julius Caesar?

Julius Caesar is a largely male-driven play. Calpurnia and Portia are the two main female characters, and they are both wives of major characters. Calpurnia is Julius Caesar’s wife. She makes public appearances with him, but there may be some awkwardness between them because of her inability to have children. He publicly tells Antony to touch Calpurnia to cure her of barrenness when he runs the Lupercal, a “holy race” and fertility festival. Calpurnia has... Julius Caesar is a largely male-driven play.

What is the probability that a cross between parents who are both homozygous recessive for trait will have offspring that are homozygous recessive...

In the question, both parents are homozygous recessive for a trait. Therefore, the only genes present in each parent's genotype would be two copies of the recessive gene.  If these parents decide to have offspring, 100% of their children will inherit two recessive alleles and will express the recessive trait. An example of this can be demonstrated with the sickle cell anemia allele. If both parents have sickle cell anemia, then all of their offspring...

The disease phenotype of sickle cell anemia re...
