When the frothy magma starts to cool, it cools too fast for the atoms to make a crystal structure so it cools with bubbles inside. Because of this, pumice is able to float.

Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabil
Zanzabum

Answer:

50% probability of Pp (purple) or pp (white) genotype.

Explanation:

P = purple gene

p = white gene

Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:

Purple flower genotype (heterozygous) = Pp

White flower genotype = pp

Punnet Square:

\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]

Potential genotypes for offspring are Pp and pp;

According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;

This means 2 should be purple and 2 white;

Or, there is a 50% chance of having either genotype, of being purple or white.

A chef fills a 40 mL container with 30 g of cooking oil. What is the density of the oil?
Nonamiya [84]

Answer:

So 1 ml=1 cm^3, so 40ml is 40 cm^3

D= m/v

density = 30/40

Density of oil is 0.75 g/cm^3 (which is verified as oil is less dense than water hence floats on it)
