Answer:
Radiometric dating often called radioactive dating is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
Explanation:
The correct answer is the G2 phase. The G2 phase is usually the shortest of the three phases pf interphase. During G2 phase, many of the organelles and molecules required for cell division are produced. When the G2 phase is completed, the cell is ready to enter Mitosis and begin cell division. Hopes this helps!
Answer:
Phototropism
Explanation:
Phototropism. Although both types of movement orient plants toward a light source, heliotropism is not the same as phototropism. Phototropism is the term that describes the growth of a plant toward any light source.
Answer;
- Proteins, nucleotides;
Amino acids are needed to build proteins just as nucleotides are needed to create DNA.
Explanation;
-Amino acids bond together to make long chains. Those long chains of amino acids are also called proteins. Protein plays a crucial role in almost all biological processes and amino acids are the building blocks of it. A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure.
-Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.
