Answer:

C) primary cell wall --> plasma membrane --> cytoplasm --> tonoplast

Explanation:

When a potassium ion moves from the ground into a vacuole of a plant cell, it must pass through the different structures that are part of it.

First, the outermost layer of the cell is the cell wall. Plant cells may have a primary and a secondary wall, but the latter is not always present. The primary wall is always located outwards (and in the case of having a secondary wall, it will be located between the primary wall and the plasma membrane).

Then, inside the cell wall, we will find the plasma membrane (also called plasmalemma).

When crossing the membrane, the ion will be in the cytoplasm of the cell and will be directed towards the vacuole, which is surrounded by its membrane called tonoplast. The vacuole is an organelle that has no definite shape, although it is always surrounded by the tonoplast, and it contains different substances such as water and enzymes.

Answer:

Explanation:

Color is determined by a sex-linked gene, X gene, so, in order to that, the gene is maternally inherited. When one gene is related to the X chromosome, and one of the alleles is recesive and the other, logically dominant, the first generation will be of a single color, and the second generation will be of the other single color.

Explanation:

Amylase is a digestive enzyme secreted and is responsible for breaking down starch.

Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food. Alpha amylase, an enzyme produced in the pancreas, is found in human saliva; it catalyzes the breakdown of starch into glucose

Further Explanation:

Food is chemically and mechanically broken down into into smaller particles. This begins in the mouth, where food is mechanically crushed by the teeth, and mixed with saliva to allow water based enzymes like lingual lipase and amylase to work;- it's then transported to the stomach via the esophagus.

Alpha amylase, an enzyme produced in the pancreas, is also found in human saliva; it catalyzes the hydrolysis, or breakdown of starch into glucose in the stomach as gastric amylase. Amylase acts on polysaccharides bonds at random points along the chain by splitting the α 1-4 glycosidic bonds.
