Answer:
The expression of genes associated with drug resistance leads to the reduction in the effectiveness of drugs against cancer cells.
Explanation:
In cancer, drug resistance is produced when oncogenic cells are able to develop mechanisms of resistance against drugs such as, for example, chemotherapeutic agents. In these cases, therapeutic treatments become ineffective to fight against cancer cells and tumor progression. In consequence, it is imperative to trace the expression of target oncogenes associated with drug resistance in order to provide effective treatments to eliminate cancer cells.
Substrate concentration affect enzyme activity -
1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached
2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.
The enzymatic reaction depends on various factors including temperature, substrate concentration, concentration enzyme, and other factors. The rate of a chemical reaction is affected by the total number of enzymes as well as the concentration of substrate
- Increasing substrate concentration increases the activity of a corresponding enzyme
- After a certain point, the rate of activity will cease to rise regardless of any further increases in substrate levels as the environment is saturated with substrate and all enzymes are bound and reacting to the maximum limit.
- A high concentration of substrate causes increases in a collision between enzyme and substrate.
- Collisions bring substrate molecules and enzymes together and increase enzymatic activity.
Thus, Substrate concentration affect enzyme activity -
1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached
2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.

Answer:
increased solar radiation
Explanation:
during summer the solar radiation can increase the bleaching of shallow living corals as tides gets lower the solar radiation increases
Correct answer: C). Cells are the basic building blocks of life but do not constitute life itself
Cell theory in a biology is a scientific theory, which is universally accepted and it states that all living organism are made up of one or more cells, cell is the building block of living thing, it also states that all cell arise from ore existing cells.
The cell theory is collection of ideas and conclusion, which were given after many years of continuous research and experiment of many scientist, which tells about the cell and how it operates.
Answer:
the fact or process of a species, family, or other group of animals or plants becoming extinct.
Explanation:
extinct means the disappearance of something meaning it is no longer alive or reproducible
