Do fossils provide evidence of organisms that lived in the past

Which of the following statements about cellular respiration is correct?

Lisa [10]

Answer:

Plants and animals use this process to produce ATP.

Explanation:

the first one is wrong because cellular respiration occurs in almost every cell

the third one is wrong because byproduct of cellular respiration is water, not oxygen(oxygen is used in the reaction)

fourth is wrong because carbohydrates are produced by photosynthesis

second option is right because cellular respiration provides energy(ATP) for cells to use(in order to perform lots of processes)

Purple petal color in pea plants is dominant to white petal color. Two heterozygous pea plants are crossed. What ratio of the of

Paladinen [302]

Mendel crossed the dominant purple colour flowered plant with the recessive white colour flowered plant. The F 1 generation produced the heterozygous purple colour flowered (Pp) plants. When two heterozygous pea plants (Pp) are crossed in the F2 generation represented by Pp x Pp, the gametes formed are P and p. Out of the offspring produced, 3 are purple colour flowered plants and 1 is white colour flowered plant. Thus the phenotypic ratio is 3: 1 with one out of four plants being white colour flowered pea plant. When expressed in percentage it is 25%.
