Have about 5 beakers all with different temperatures of water. Put in a teaspoon of salt at a time and when it stops dissolving stop adding and record how much salt it took. It should be more salt as the temperature rises. The independent variable is the waters temperature. The dependent variable is how much salt is used. Make sure that there is the same amount of water in each beaker. Or else it won’t work.
Answer:
C
Explanation:
The genotype of an organism is the combination of alleles it has at a particular locus. In contrast, the phenotype is the observable characteristics that are produced by the genotype.
B and D are phenotypes, and are therefore not possible genotypes.
In a cross between tt ff and TT FF, the only alleles that tt ff can pass on are t/f, and the only alleles TT FF can pass on are T/F. Therefore, the only possible genotype is Tt Ff
Answer:
Substance 4
Explanation:
Density is defined as mass per unit volume. A substance floats in another when its density is less than that of the substance on which it floats.
If an object is immersed in a denser liquid, it will sink
Since the density of water is 1 g/cm^3, any substance whose density is less than that of water will float in it.
If we look at the table, substance 4 has a density of 0.5g/cm^3. Hence, substance 4 is expected to float in water.
