10 Questions
What is the source of genetic information for cells and viruses?
Nucleotides
How do autotrophs gain energy?
Through internal methods and by making their own energy.
What is the process where stored energy like glycogen is broken down into smaller molecules, releasing energy?
Catabolism
Name the process where smaller molecules use energy to build a lot of molecules.
Anabolism
What is the pH of the stomach due to hydrochloric acid?
pH of 2
What is the genetic material that has the capacity to store information?
DNA
What is the smallest unit that can make matter?
Atoms
Explain the difference between gene expression and DNA.
Protein is the gene expression of DNA.
What is the most complicated system mentioned in the text?
Biosphere
Define 'population' based on the text.
Group of one species living at a particular place at a particular time
Study Notes
Genetic Information and Energy Production
- Genetic information for cells and viruses is stored in DNA or RNA.
- Autotrophs gain energy through photosynthesis.
Metabolic Processes
- Catabolism is the process where stored energy like glycogen is broken down into smaller molecules, releasing energy.
- Anabolism is the process where smaller molecules use energy to build a lot of molecules.
Human Biology
- The pH of the stomach is due to hydrochloric acid, which keeps it acidic.
Genetics
- DNA is the genetic material that has the capacity to store information.
- Gene expression refers to the process by which the information in a gene's DNA is converted into a functional product, whereas DNA is the genetic material itself.
Atomic Structure
- Atoms are the smallest unit that can make matter.
Ecology
- A population is a group of individuals of the same species living in a specific geographic area.
- The most complicated system mentioned in the text is likely the human body, considering its complex biology and physiology.
