Does salt make noodles cook faster?

Readme [11.4K]

In fact, adding salt does the very opposite of making water boil faster. Instead, itmakes it take longer for the water to boil! The salt actually increases the boiling point of the water, which is when the tendency for the water to evaporate is greater than the tendency for it to remain a liquid on a molecular level.

In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the

Goryan [66]

Answer:

9:3:3:1

Explanation:

This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).

According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:

TtPp - TP, Tp, tP, tp

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

T_P_ (tall, purple) = 9

T_pp (tall, white) = 3

ttP_ (short, purple) = 3

ttpp (short, white) = 1

Hence, the ratio of this cross is 9:3:3:1
