Adhesion of water molecules
Cohesion of water molecules
High specific heat capacity
High density
Answer explanation
The property that allows insects to walk on water is the cohesion of water molecules. This cohesion creates surface tension, enabling small insects to stay on the surface without sinking.

Where do hydrogen bonds form?
Between the slight negative charge of hydrogen and slight positive charge of oxygen within a water molecule
Between the slight positive charge of hydrogen and slight negative charge of oxygen within a water molecule
Between the slight positive charge of hydrogen and slight negative charge of oxygen in different water molecules
Between the slight negative charge of hydrogen and slight positive charge of oxygen in different water molecules
Answer explanation
Hydrogen bonds form between the slight positive charge of hydrogen in one water molecule and the slight negative charge of oxygen in another water molecule, allowing for the unique properties of water.

What prevents plants from converting carbon dioxide into glucose in the dark?
They do not have a source of energy.
It is too cold.
They do not require glucose during the night.
Their enzymes are inhibited.
Answer explanation
Plants require light to produce energy through photosynthesis. In the dark, they lack the necessary energy source (light) to convert carbon dioxide into glucose, making this the correct choice.

What cell component is found in eukaryotic cells but not in prokaryotic cells?
Mitochondria for respiration
DNA containing genetic information
Ribosomes for protein synthesis
Cell wall to maintain shape
Answer explanation
Mitochondria are organelles responsible for respiration and energy production, and they are present in eukaryotic cells but absent in prokaryotic cells. The other options, such as DNA and ribosomes, are found in both cell types.

What is a consequence of anaerobic cell respiration in muscles?
Large yield of readily available ATP and ethanol production
Small yield of readily available ATP and lactate accumulation
Large yield of ATP and production of carbon dioxide and lactic acid
Small yield of ATP that is not readily available and carbon dioxide production
Answer explanation
Anaerobic respiration in muscles results in a small yield of ATP due to the lack of oxygen. This process leads to lactate accumulation, which can cause muscle fatigue, making the correct choice "Small yield of readily available ATP and lactate accumulation."
