Answer:

If I add sugar or salt, the water's density will increase.

Explanation:

Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.

If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.

We can use numbers to understand it better.

Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l

δ= 1g/l1t

δ= 1 g/lt

Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.

δ= 2g/1lt

δ= 2g/lt

We can see that the density increased when the mass increased.

Assume that in cattle a spotted coat is dominant to an even coat, short horns are dominant to long horns, and the traits for coa

kow [346]

Answer:

C. 1/4

Explanation:

Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=

9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.

Therefore, the proportion of the progeny with long horns = 4/16= 1/4
