Science Exploration

What is the purpose of experimental design in scientific research?

• To determine the hypothesis for the research

• To randomly select participants for the experiment

• To analyze the data collected from experiments

• To systematically plan and conduct experiments

Describe the process of cell division in eukaryotic cells.

• Mitosis

• Budding

• Binary fission

• Meiosis

What are the main differences between prokaryotic and eukaryotic cells?

• The main differences are the size and shape of the cells.

• The main differences are the presence of a nucleus and membrane-bound organelles.

• The main differences are the types of genetic material present.

• The main differences are the methods of cell division.

How do enzymes function as catalysts in biological reactions?

• Enzymes increase the activation energy of biological reactions.

• Enzymes have no effect on the activation energy of biological reactions.

• Enzymes convert biological reactions into non-biological reactions.

• Enzymes lower the activation energy of biological reactions.

What factors can affect enzyme activity?

• Time, pressure, enzyme size

• Light intensity, enzyme shape, concentration of water

• Temperature, pH, substrate concentration, enzyme concentration, and presence of inhibitors or activators

• pH, enzyme size, concentration of water

Explain the concept of cell membrane permeability.

• Cell membrane permeability is the process by which cells absorb nutrients.

• Cell membrane permeability is the movement of cells through the bloodstream.

• Cell membrane permeability refers to the ability of substances to pass through the cell membrane.

• Cell membrane permeability is the ability of cells to divide and reproduce.

What are the major organelles found in animal cells and their functions?

• The major organelles found in animal cells are the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes.

• The major organelles found in animal cells are the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and chloroplasts.

• The major organelles found in animal cells are the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and vacuoles.

• The major organelles found in animal cells are the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes.

Describe the process of photosynthesis in plant cells.

• Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen.

• Photosynthesis is the process by which plants convert sunlight, carbon monoxide, and water into glucose and oxygen.

• Photosynthesis is the process by which plants convert moonlight, carbon dioxide, and water into glucose and oxygen.
