I) Predict which of the liquids would cause the largest decrease in mass of a potato stick
rjkz [21]

Answer:

1.0 mole per dm3 sodium chloride solution

Explanation:

<em>The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established. </em>

Hence,<u> the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick</u> when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.

Several structures work together to allow flowering plants to reproduce. The diagram shows a typical flower. Which table correct
seraphim [82]

According to the image, X is for attracting pollinators, Y is for the production of pollen, and Z is for the production of eggs

<h3>Parts and functions of flowers</h3>

The image shows the different parts of a typical flower.

X is a petal. Petals are usually colorful and serve to attract insect pollinators to flowers.

Y consists of the anther and the stigma. Both represent the male organ of the flower and produce the male gametes, otherwise known as pollens.

Z consists of the stigma, the style, and the ovary. They all represent the female reproductive organ of the flower. Pollen lands on the stigma, travels through the style, and reaches the ovary. The ovary houses the ovule or the eggs.

What are Genes that produce alternative expressions of a trait called
Brrunno [24]
The answer should be allele(s).

Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes. 

However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing. 

An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
