Answer:
duplicate their chromosomal DNA prior to nuclear division
Explanation:
Mitosis and meiosis both involve duplication of a cell's DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells.
B) Bacteria can be treated with antibiotics, viruses cannot.
Antibiotics have no target when dealing with viruses. Antibiotics work on bacteria because it targets the growth machinery in bacteria. Viruses are found inside a human cell and reproduce by inserting their DNA into a human cell. There are antivirals and vaccines out there for viruses. Our body’s immune system fights against viruses with antibodies!
Answer:
In anaerobic respiration , one molecule of glucose is broken down into two molecules of pyruvate which are then converted to lactate
Explanation:
Cellular respiration is the process by which cells metabolize glucose through various steps and pathways to produce energy in the form of ATP molecules. Cellular respiration is of two types: aerobic and anaerobic respiration. Oxygen is present in aerobic respiration to accept the electrons produced in glycolysis whereas it is absent in anaerobic respiration.
In anaerobic respiration, glucose is broken down in ten reaction steps into two molecules of pyruvate. Two net ATP molecules are also released.
The overall equation for glycolysis is: glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O
The two pyruvate molecules produced are then converted to lactate when they accept electrons from NADH molecules. The equation is given below:
2 pyruvate + 2NADH ⟶ 2 Lactate + 2 NAD+
