Answer:
By lowering the levels of total cholesterol and low density lipoprotein (LDL)
Explanation:
Dietary fibers are classified into two: the soluble fiber and the insoluble fiber. Studies have show that the soluble fiber play a significant role in lowering blood cholesterol, hence reducing the cardiovascular diseases.
Soluble fiber helps to lower blood cholesterol by its ability to bind to the small intestine which further binds to cholesterol most especially the ad cholesterol (low density lipoprotein). Binding of Fibers to cholesterol prevents them from migrating to the blood stream and to other parts of the body. Since cholesterol can't get into the bloodstream, it exits the body through feces. Fiber has more effect on lowering LDL (bad cholesterol) than High density lipoprotein (good cholesterol.
Mutalism, commensalism, and parasitism
Answer:
Dermis
Explanation:
The hair follicles are present in the dermal papillae of the dermis layer. The dermal papillae are a series of triangular-shaped cells. The hair follicles are extending from the skin surface to the dermis layer of the skin. The hairs are the extension of the epidermis layer into the dermis layer of the muscle. The hair follicle has 2 parts, such as - the part which extends outside of the epidermis known as the shaft. The base of the follicle known as root. The hair follicle itself has different parts - outer root sheath, inner root sheath, and a centrally placed hair shaft. The erector muscles help in goosebumps of hair during cold.
Answer:
Ecological succession refers to the changes taken place in a forest over a particular period of time.
Succession is usually influenced by environmental factors such as water regimes, soil type, climate, vegetation history, and invasive species.
Humans interventions affect all of the above-mentioned factors.
Human activities such as fragmentation of forests, clearing of forests for agricultural practices, construction of dams, civilization, logging et cetera drastically reduce the biodiversity of a forest.
This reduction of biodiversity forms the foundation for a secondary succession of a forest.
