Answer:
Ecosystems are characterized by the cycling of chemicals and by the flow of energy. Both of these begin when photosynthesizing organisms take in solar energy and inorganic nutrients to make organic nutrients. These organic nutrients move up through the food chain until death occurs and decomposition returns the nutrients to the earth. In this manner, chemicals are cycled throughout an ecosystem. As these organic nutrients move up the food chain, energy moves along with them. With each level of the food chain, some of this energy is lost as heat. In this manner, energy flows through an ecosystem and does not cycle.
Explanation:
Chemicals is the term used in general to refer to simple molecules or substances formed by two or more atoms. They can be classified as organic, most of which are formed by carbon and hydrogen and derive from biological processes, and inorganic, with other compositions.
Energy, on the other hand, is the capacity of performing a reaction or movement. It is necessary for processes in which one chemical is transformed into another one. One form of energy is the one contained in atomic bonds (chemical energy), but there are many other forms.
Photosynthesis is the process by which plants and other organisms transform inorganic matter into organic. They use the energy contained in sun rays to perform this task, inside complex structures called chloroplasts.
I think the correct answer is

Sorry if it's wrong
MRNA = A, C ,G ,U
TRNA = T, G,C,A
Answer:
75% chance of having four normal phenotype children without albinism.
50% chance of having four children who are carriers of the gene with normal phenotype.
Explanation:
Albinism results from an autosomal recessive gene. In order to solve this problem we have to draw a punnet square and figure out the genotypes of the parents. So with the genotype of the parents both parents have to be carriers of the trait since it is an autosomal recessive trait.
Genotype of female I-1 = Aa
Genotype of male I-1 = Aa
PARENTS A a
A AA Aa
a Aa aa
75% chance of having four normal phenotype children without albinism.
50% chance of having four children who are carriers of the gene with normal phenotype.
25% chance of having children with albinism.
Electron transport trains create a concentration gradient of hydrogen ions outside the mitochondria and fewer inside the mitochondria and creates energy(ATP) by diffusing the hydrogen ions back in
