The exchange of oxygen, food, and waste between mother and fetus occur in the placenta.
The majority of photosynthesis is done by plants
The National government has always wanted to increase the number of National Parks and recreation areas for citizens. This act will help with the sustainability of our environment by preserving biodiversity for our future generations. This will make D the correct answer. <span />
Answer:
This question lacks options, the options are:
A. The sequence of DNA determines the structure of lipids, which produce phenotypes.
B. The sequence of DNA determines the structure of proteins, which produce phenotypes.
C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.
D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.
The answer is B.
Explanation:
DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.
An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).
Answer:
ATP and NADPH
Explanation:
The second stage of the Calvin cycle is the reduction in which 3-Phosphoglycerate is reduced into Glyceraldehyde 3-phosphate by a series of reactions. These reactions consume ATP as an energy source and NADPH as an electron donor. ATP and NADPH for produced during the light-dependent phase of photosynthesis. Transfer of electron through ETC generates proton concentration gradient across the thylakoid membrane which in turn drives ATP synthesis. Electrons released from water splitting finally reach NADP reductase enzyme that reduces NADH into NADPH.
