Answer: Annelida
Leeches are soft bodied segmented parasitic worms. They belong to the phylum Annelida. They are hermaphrodites which means they exhibit sex organs of both male and female.
The characteristics which are found in leeches which group them into Annelida are:
1. The body of the leeches are bilaterally symmetrical like other Annelids. The body organs are also segmented.
2. They have a closed circulatory system in which the heart pumps the blood to all the parts of the body.
3. Leeches either exhibit a protusible pharynx or proboscis which allows them to suck the blood of the host such features are also common in other Annelids.
Answer:
The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.
Explanation:
The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.
<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated
.
The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.

Carbohydrates are a macronutrient whose main function is to provide energy to the body. All digestible forms of carbohydrates give 4 calories per energy of energy. The fiber, starch, and glycogen are complex carbohydrates. Simple carbohydrates can be monosaccharides, like glucose and galactose or disaccharides like lactose and maltose.
Complex carbohydrates include polysaccharides. Starch comprises of chains of glucose molecules. Some chains of starch are straight and are harder to digest. Another starch is much easier to digest and has branching chains.
Dietary fiber comprises soluble and insoluble types and both possess essential benefits like minimizing the risk of heart disease, constipation, and obesity. Soluble fiber also helps to reduce the threat of diabetes.
Glycogen is a highly branched polysaccharide created by a procedure known as glycogenesis and is stored in the liver and muscles for later use. Carbohydrate in the diet is said to spare protein from being used to provide energy for fuel for the cells.
