Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
Answer: I thinks it’s a. A guess about a scientific idea
Explanation:
In cells, the vacuole is the organelle in which different substances or solutions are stored, this includes wastes, water, food, and even solids that the cell does not require because they are waste and therefore might contaminate the cell or substances the cell store to be used later.
Variation - different appearance and behavior
inheritance- traits passed on from parent to offspring
growth in population
and survival and reproduction
D. melting is a phase change from a solid to liquid.
e.g ice melts
