Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
During mitosis a cell duplicates its DNA and divides into two genetically identical cells mitosis is typically followed by cytokinesis which divides the other properties if the cell including cytoplasm, organelles and the cell membrane.
Answer:
The correct answer is synapse, electrical signals, neurotransmitters.
Explanation:
Neuron communicates with other neurons via action potentials and chemical neurotransmitters through the synapse.
Two neurons form a junction that is termed as a synapse, there an action potential that results in neuron A to release a neurotransmitter (chemical).
Synapses are thought of as the site of converting an electrical signal into a neurotransmitter release which is a chemical signal.
Thus, the correct answer is synapse, electrical signals, neurotransmitters.
Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most carbon enters the atmosphere as carbon dioxide.
