Answer:
Low cost has low quality whereas high cost has high quality.
Explanation:
If the main criterion was keeping the cost of materials as low as possible so he must used the materials of low quality for their work because the low quality materials are made of cheap material while on the other hand, if the main criterion was getting the best performance from the material so he has to used the materials of high quality. The high quality materials are very expensive but its performance is excellent as compared to cheap materials.
give an example of something that might stop a cell from checking things during the cell cycle
Answer:
A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. ... The G2 checkpoint ensures all of the chromosomes have been replicated and that the replicated DNA is not damaged before cell enters mitosis.
A mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.
Tumor suppressor genes are normally expressed genes that control the progression of a cell through the cell cycle.These genes (tumor suppressor genes) act to repair mutations that occurred during DNA replication, slow down cell division, activate programmed cell death pathways (i.e., apoptotic pathways, etc).For example, p53 is a tumor suppressor gene capable of controlling cell division rate by keeping cells from proliferating in an uncontrolled manner.In consequence, mutations of the p53 gene are often observed in cancer cells that lost their ability to regulate the rate at which they grow.In conclusion, a mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.

If an acorn falls off a tree, is it living or non-living??
Answer: living
Acorns are still alive even off the tree and eventually grow into plants in the right conditions.
Answer:
Acorns are alive. Acorns live and breathe. Since they have no teeth and claws, acorns defend themselves with have chemicals called tannins. Because acorns decompose slowly, some gardeners compost them separately from other materials that break down more rapidly. Others grind them before composting them, as this speeds up decomposition.
therefore they are still living
