The DNA (deoxyribonucleic acid) is the hereditary material present in an organism. The DNA is divided into different segments, which codes for specific traits.
The stretch of the DNA, which codes for a specific sequence of amino acids is known as gene. The gene is the basic functional unit of the hereditary, and codes for a specific protein (not all the genes are involved in protein formation).
Hence, the given blank can be filled with gene.
Answer:
c. This statement is true because plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants.
Explanation:
Green plants are autotrophs. They synthesize their food in the presence of sunlight, using carbon dioxide gas and water. Whereas animals are heterotrophs, they cannot make their food but use food prepared by green plants. Thus, plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants. The statement is true.

Answer:
Oxygen and pyruvate.
Explanation:
The krebs cycle is a stage of cellular respiration and occurs in aerobic organisms. In this case, we can say that the Krebs Cycle only occurs in the presence of oxygen, being essential for the completion of cell respiration.
The Krebs cycle only occurs after the completion of glycolysis, as it needs to be initiated by pyruvate, which is a molecule resulting from glycolysis. In this case, in addition to oxygen, the presence of pyruvate is essential for the krebs cycle to occur.
