Answer:
The correct answer would be c) food molecules.
A vacuole is a membrane-bound cell organelle present usually in the center of the plant cell.
It contains a high amount of water as it plays important role in maintaining the turgor pressure of the cell.
In addition, it contains a high amount of ions (such as K⁺, Mg²⁺, Ca²⁺), food molecules (such as glucose, sucrose, fructose), organic acids (such as malic, tartaric, quinic) and waste material.
The Precambrian eon is separated from the Phanerozoic eon in the fossil record because of the sudden appearance of organisms.
Explanation:
Precambrian eon is the initial existence on earth that can be predicted by the study of rocks and remaining of fossils. It has been seen as the existence of skeleton in this era, before this era no such things has been observed, even the development of sexual reproduction.
The Phanerozoic era comes after the Precambrian era, more advanced kinds of fossils of animals had been observed in this era. Phanerozoic era period of life on earth. Large organisms sudden appearance are seen in the Phanerozoic era i.e. First dinosaurs, mammals, fishes, angiosperms,first vertebrates etc.
Answer:
The answer is C
Explanation:
That is the only one they have in common.
Answer:
16. Directional Selection
17. Disruptive Selection
18. Stabilizing Selection
19. Natural Selection
20. Adaptation
Explanation:
In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.
Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.
Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.
Answer:
The rocky, brittle lithosphere cracks. These cracks are called faults.
