Cellular respiration is a series of metabolic reactions in which biochemical energy from nutrient is converted into ATP. In cellular respiration, glucose and oxygen yield water and carbon dioxide.
So, a general reaction could be represented as:
Answer:
Polymerase chain reaction is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail.
Explanation:
that's the answer
B. glucosamine.
C. insulin.
D. vitamin D.
The molecule responsible for heredity, which encodes and transmits information in organisms is DNA. Therefore, the correct statement is option A.
In the 1940s and 1950s, scientists such as Avery, MacLeod, McCarty, Hershey, and Chase demonstrated that DNA was the genetic material. When DNA was damaged, the genetic information was not passed on, and also when DNA was introduced to a cell, it could change the characteristics of the cell.
This discovery was a breakthrough, and also led to the development of new technologies, which allow scientists to manipulate or modify DNA for other applications.
The discovery that DNA explained how genetic information is inherited from one generation to the next generation. This discovery also leads to important breakthroughs in medicine, agriculture, and biotechnology by developing treatments for genetic diseases and creating genetically modified crops.
Therefore, DNA is the molecule responsible for heredity, which encodes and transmits information in organisms.

Answer and Explanation:
All cells including the gametes contain chromosomes. Each gamete cell after cell division contains 23 chromosomes. After fertilization, the diploid number of chromosomes which is 46 is restored in the zygote.
Meiosis, a type of cell division, has two phases which eventually lead to the formation of four daughter cells with equal number of chromosomes. Gametes are haploid in nature and thus meiosis I involves separation of homologous chromosomes hence the reduction in the chromosome number. Meiosis II involves separation of sister chromatids in the daughter cells resulting in four daughter cells with 23 chromosomes.
Meiosis ensures that chromosoe number does not double with each successive generation as the resulting daughter cells are gametes, two of which must fuse to form a zygote.
