Which type of molecule acts as a signaling molecule in yeasts?
steroid
autoinducer
mating factor
second messenger

The correct answer is the option - mating factor.

Explanation:

Yeast can reproduce sexually by a signaling pathway called the mating factor pathway. Mating in yeast occurs between two haploid yeast cells. In this process, two yeast cells form a diploid cell.

In this process yeast cells secrete a signaling molecule termed as the mating factor that is used to attract them to mating cells to form a diploid cell.

Thus, the correct answer is option - mating factor.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
