Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome, where it matches its anticodon with the codon on mRNA to facilitate protein synthesis.

Front

Is tRNA responsible for carrying information from DNA to ribosomes?

Back

False. tRNA carries amino acids, while mRNA carries the information from DNA to ribosomes.

Front

What is the significance of examining different hominoid skulls?

Back

Examining hominoid skulls provides evidence of evolution and helps understand the evolutionary relationships among species.

Front

What is the purpose of using a pH indicator in photosynthesis experiments?

Back

A pH indicator is used to observe changes in pH levels, which can indicate the production of oxygen during photosynthesis.

Front

Why is methylene blue used in respiration experiments with yeast?

Back

Methylene blue is used to visualize which cells are undergoing respiration by staining the cells that are metabolically active.

Front

What is the function of a pH indicator in the exhaled air experiment?

Back

The pH indicator helps to detect changes in acidity, indicating the presence of carbon dioxide in exhaled air.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, carbon dioxide, and water.
