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.
To help work place with the system
Answer:
Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. So identical twins with identical DNA may have different genes turned on, causing them to look and act differently, and even to develop different diseases such as cancer.
Explanation:
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
hope this helps :)
can i have a brainilist pls
The difference is cancer cells need to be provided with nutrients and they may grow indefinitely until one day they in the cycle they stop rather then stopping at ''checkpoints'' but in the normal cells making they some what ''immortal'' lol these is the most common difference
