He noticed that each pigeon from each different island in the Galápagos Islands had a different type of beak. Noticing that each bird had a different beak, he connected it to the different environments of each island. He came to the conclusion that the environment of where each bird was determined how their beaks would be shaped. This lead to his theory of natural selection.
Answer:
- Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
- Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.
Explanation:
DNA and RNA are both made up of chains of nucleotides. They are responsible for holding, transmitting, and translating genetic information into proteins.
Nucleotides are made up of a 5 carbon sugar, (DNA is deoxyribose, RNA is ribose), a phosphate group, and a nitrogenous base. They are linked together by phosphodiester bonds. The sequence of nucleotides makes the DNA and RNA sequences unique and determines the structure and function of the encoded proteins
Answer:
If the salts are not filtered from the transpiration stream, they can damage the plant.
If excluded by the root, the salts can make it harder for the root to extract water from the soil.
Explanation:
When soil has high salt concentration, it becomes very difficult for the plant to take in water. Sometimes the problem becomes so peculiar that plant becomes completely unable to take in the water and hence they wilt and die. This happens even when the surrounding soil has sufficient water but remains un-drawn by the plants due to its high osmotic potential resulting due to highly concentrated salt solution. Therefore, more energy and effort is required by roots to extract water from salty sand.
Also if the salt concentration with in the plant increases, it remains there and causes damage
Hence, correct options are
If the salts are not filtered from the transpiration stream, they can damage the plant.
If excluded by the root, the salts can make it harder for the root to extract water from the soil.
Answer:
C
Explanation:
Fission and fusion are two processes that release very large amounts of energy
