<u>Answer</u>: The cell membrane takes in nutrients that the ribosomes use to create essential proteins for cell growth and reproduction.
Nutrients are absorbed by duffision via the cell membrane. Ribosomes are the organelles responsible for the production of proteins, known as protein synthesis.
Answer:
Semi-conservation replication describes the mechanism of DNA replication in all known cells. This process is known as semi-conservation because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
DNA is passed down to the next generation in big chunks called: Chromosomes.
Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around a 1 in 8 change that you would get no DNA from a great, great, great, great grandparent.
What most people forget, through, is that our chromosomes get mixed and matched before they are passed on. It is because of this "recombination" that your great, great, great grandparent's DNA is almost cetainly still lurking in yours.

Answer:
In the given example, malonic acid is the competitive inhibitor of succinate.
Explanation:
- When a substance diminishes the velocity of an enzyme catalyzed reaction then it is called inhibitor.
- These inhibitors can bind to enzyme in a reversible or irreversible fashion.
- Reversible inhibitor binds to enzyme by non-covalent bonds.
- There are two types of enzyme inhibition: Competitive and non-competitive.
- Competitive inhibition: We use the term competitive if the inhibitor binds to enzyme reversibly at the same site as substrate would bind.
- Here in this example, both succinate and malonic acid have same binding site on enzyme i.e the active site. Since both can bind to the same site, inhibitor competes with the substrate for that site.
- By increasing the concentration of substrate, we can reverse the effect of competitive inhibitor.
- At a sufficiently high concentration of substrate, V-max can be achieved for the reaction. In the Michaelis-Mentens curve we can observe increase in the Km value in the presence of competitive inhibitor.
Answer:
Viroids are molecules of RNA are not classified as viruses
Explanation:
because they lack a protein coat. They have characteristics that are common to several viruses and are often called subviral agents. Viroids are important pathogens of plants.
