Answer:
a.energy source ,either sunlight or chemicals
Explanation:
the animals using sunlight are known as photoautotrophs and the animals using chemicals are known as chemoautotrophs.

Question: When crossing two individuals, the offspring display only one of the two traits found in parents. Which principle of Mendelian genetics is supported by this observation?
a) segregation
b) independent assortment
c) dominance and recessiveness
d) allele frequency
Answer:
c) dominance and recessiveness
Explanation:
According to Mendel's principle of dominance and recessiveness, the alleles of one gene may be dominant or recessive in nature. When present together, only the dominant allele is able to express itself. Therefore, a hybrid individual for a gene would express only the dominant phenotype. In the given cross, the progeny express only one of the two traits found in the parents. This means that the progeny is heterozygous for the trait and is expressing the dominant trait. The recessive trait is not expressed due to the presence of the allele for the dominant trait.
Answer:
In C4 photosynthesis, where a four-carbon compound is produced, unique leaf anatomy allows carbon dioxide to concentrate in 'bundle sheath' cells around Rubisco. This structure delivers carbon dioxide straight to Rubisco, effectively removing its contact with oxygen and the need for photorespiration
Answer:
Peristalsis moves the food along the digestive tract.
Explanation:
brainliest?
Answer: The correct answer for the blank is-
B) Sugar and oxygen.
Explanation:
Cellular respiration can be described a metabolic process that includes the break down of organic molecule like glucose (a carbohydrate or sugar) to form carbon dioxide and water along with large amount of energy in the form of ATP ( adenosine triphosphates), which is used for driving various cellular processes.
Aerobic cellular respiration involves the presence of oxygen along with glucose.
Thus, sugar and oxygen, being the reactants in cellular respiration is the right answer.
