Answer:
Magnet, water, coffee filter.
Explanation:
The magnet will pick up the iron filings, and the water will dissolve the sugar and leave the sand. Next add the sand to a coffee filter and squeeze the sugar-water liquid. You have now successfully separated each specimen.
The answer would be C. The mass of the object
Answer:
Whether a cell uses facilitated diffusion or active transport depends on the specific needs of the cell. For example, the sugar glucose is transported by active transport from the gut into intestinal epithelial cells, but by facilitated diffusion across the membrane of red blood cells.
Explanation:
The answer is (C) Replication
Though occasional errors could occur in cells during replication; the cells have error checking and proofing mechanisms that reduce the rate of error to one to several million replications in higher eukaryotes.
After all, one mismatch error during replication would not result in major effects. The others choices, however, have higher rates of causing genetic abnormalities.
Answer:
An individual whose genotype is heterozygous cannot be for the recessive
Explanation:There are two possible genotypes either homozygous dominant or heterozygous dominant. For a charecter there can be two gene .One is recessive and other one is dominant. In presence of the dominant gene the recessive gene of the same character cannot express . IF recessive gene is homozygous then only it will express .Therefore for the individual it is heterozygous for the dominant
