Answer:

Phospholipid bilayer and carbohydrates.

Explanation:

Phospholipids form a double layer that protects the cell from the outside, in this layer the heads of the phospholipids, which are hydrophilic, are orientated towards the inside and the outside of the cell, and the tails of the two layers, which are hydrophobic, are in contact with each other. This bilayer allows the passage of certain substances due to its polarity, the elements that are too big, are ions, or that are hydrophilic have especial channels made of proteins that allow the passage of these kinds of elements

The other component that can affect the permeability is carbohydrates. These, when they attach to lipids and proteins, form a layer around the cell that allows the passage of certain substances, allows the recognition of the cells that are from the body, and the ones that are foreign so that there can be communication between cells.

In FIVE sentences, tell me how culture impacts the demand for jobs in agriculture.
Galina-37 [17]

Answer:

Find the explanation below.

Explanation:

Culture refers to the way of life practiced by people, and their way of life includes their values, customs, language, beliefs, knowledge, and traditions. Culture would impact the demand for jobs in agriculture depending on the value a group of people places on agriculture. In most African cultures, for example, agriculture is highly valued and even some agricultural seasons are celebrated, an example is the New Yam festival celebrated by the Igbos in Nigeria. For such cultures, the demand for jobs in agriculture would be high because it is a treasured part of their lives.

However, for cultures that view agriculture as a strenuous activity, and place more emphasis on white-collar jobs, the demand for agricultural jobs in such climes would be low.
