What are the similarities between solar and coal energy?

Solar energy originates with the Sun. It can be captured by plants and other producers for the process of photosynthesis. As a result of this process, solar energy is converted to chemical energy in the form of glucose molecules. Glucose can be in turn eaten by herbivores and these organisms can be eaten by other organisms in a food chain. When an organism dies, bacteria and fungi known as decomposers, consume dead organisms and obtain...

Solar energy originates with the Sun. It can be captured by plants and other producers for the process of photosynthesis. As a result of this process, solar energy is converted to chemical energy in the form of glucose molecules. Glucose can be in turn eaten by herbivores and these organisms can be eaten by other organisms in a food chain. When an organism dies, bacteria and fungi known as decomposers, consume dead organisms and obtain energy.  All of this energy is indirectly from the Sun. 


Coal is formed from the remains of ancient trees that lived in the Carboniferous era. It was hot and they lived in a swampy environment. Through burial and compression over time, the remains of these ancient trees became coal. Coal contains stored chemical energy and this energy originally came from solar energy that kept these ancient trees alive.


What is really occurring here is the process of energy transformation. Energy cannot be created or destroyed but it can be transformed from one form to another. Solar energy is transformed to chemical energy in plants and this energy can be eaten as seen in a food chain, or it can be used to heat a home as seen in power plants which use coal's stored chemical energy to generate electricity. This shows the relationship between solar and coal energy.


I have included a link which has a virtual lab showing energy transformations and another that has a diagram illustrating the same concept.

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... 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 sense of guilt, and that man tells him: Despair thy charm. And let the angel whom thou still hast serve...

Discuss movements that were inspired by the Civil Rights Movement and list one success for each group.

African-Americans contributed in a very big way during World War II. These contributions were demonstrated at home and on the battlefield. After the war, African-Americans properly felt it was time for them to achieve equality with white Americans. During the 1950's, the modern Civil Rights Movement was born and it had a number of successes (integration of the military and Brown vs. Board of Education as examples.) This success inspired other activists to demand change... African-Americans contributed in a very big way during World War II. These contributions were demonstrated at home and on the battlefield.

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... In the question, both parents are homozygous recessive for a 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 will have the disease phenotype. The disease phenotype of sickle cell anemia re...
