Answer:

The correct answer is - flagellated sperm.

Explanation:

In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.

Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.

<h3>What is starch ?</h3>

A polymeric carbohydrate called starch, also known as amylum, is made up of a lot of glucose units connected by glycosidic linkages. The majority of green plants synthesize this polysaccharide as a form of energy storage. It is the most prevalent type of carbohydrate consumed by people worldwide and is present in significant proportions in common foods like wheat, potatoes, maize (corn), rice, and cassava (manioc).

Pure starch is a powder that is white, odorless, tasteless, and insoluble in alcohol or cold water. It is made up of the branching amylopectin and the linear and helical amylose molecules. Starch typically comprises 20 to 25% amylose and 75 to 80% amylopectin by weight, depending on the plant. Animals store their energy in glycogen, which is a more intricately branched form of amylopectin.

Nephrons function by filtering blood and then removing needed substances from the filtrate before eliminating the remaining fluid that contains water, metabolic waste, and toxins.as urine. This process occurs through three stages which are ultrafiltration, selective reabsorption and osmoregulation.

Yuri [45]

Answer:

Emulsifier

Explanation:

Emulsifier are the chemical additives which are required to breaking up fats or lipids globules into much smaller emulsion droplets.

An emulsifier consist of one oil-friendly and one water-friendly end. When an emulsifier added with fat or lipid, the emulsifier face towards the oil/water or air/water interface reduces the surface tension to make emulsion more stable.

Emulsification of fat makes the food easy to absorbed by small intestine.

Hence, the correct answer is "Emulsifier ".
