Cell theory is one of the foundations of biology. The observation of Robert Hooke,Anton Van Leeuewenhoek,Matthias Schleiden,Theodor Schwann,Rudolf Virchow, and others led to the devolepment of the cell theory.
Answer:
D
Explanation:
A: to create sex cells of reproduction.
This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.
B. to provide the cells with food
This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.
C. To give the cell energy
This would be cellular respiration. It turns food and glucose into usable energy called ATP.
D.
This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.
less energy will be wasted
Answer:
Biological catalyst has to be cut.
Explanation:
- Enzymes are called "Biological catalyst".
- Enzymes are called Biological catalysts because they diminish the activation energy for reactions. As the activation energy is reduced the rate of reaction is increased.
- Many enzymes modify their state when substrates bind and it is known as "Induced fit".
- Enzymes are nothing but Protein(Biological molecules). Most of the biological reactions are catalyzed by Protein.
- Enzymes improve the rate of synthetic reactions without getting altered forever by the reaction.
- For this reason Biological catalyst are needed to be cut and copy segemnte in DNA.
Answer:
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Explanation:
A good hypothesis in the given case is that inflating basketball is getting warmer, the more it is pumped, and as a result, it would possess more heat or more friction due to all the air being pumped into the basketball at a single time.
hope this helped!
