Answer;
-Cell wall
Explanation;
-The cell wall is thick and fibrous and provides a barrier between the cell and its external environment.
-The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.
-A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include: Support: The cell wall provides mechanical strength and support.
Cell wall supports and maintains the cell's shape and protects the cell from damage (option B)'
The plant cell is protected by a layer called the cell wall, which encloses the cell membrane. This rigid structure, composed of cellulose offers both support and safeguarding functions, for the cell. Additionally the cell wall plays a role, in preserving the cells shape and preventing it from rupturing when exposed to pressure.
The cell membrane on the hand forms an outer layer encompassing every type of cell.

The option C, which is, Inactive people use more energy so they should consume fewer calories is not true about energy balance.
Energy balance refers to the relationship between the energy in and energy out. Energy balance is affected by the amount of exercise one gets and their dietary habits. Stored body fat will increase if calorie intake is greater than the energy used.
Stored body fat will increase if calorie intake is greater than the energy used. Energy balance is the balance between the number of calories consumed and the amount of energy used.
The difference between the number of calories consumed and burned each day is energy balance. An inactive person uses less energy as compared to an active person due to less work out and therefore would require fewer calories.
Further Explanation:
The difference between input and output energy or calories is the energy balance of the body. The energy balance can be categorized as;
a) Perfect balance: In the energy equation if the input and output difference in energy comes out to be zero, then one has a perfect energy balance. This means neither weight is lost nor gained. During the weight loss journey, the people in their weight maintenance stage show perfect energy balance.
b) Positive energy balance: If the difference in the energy input and output results in a positive number, a person gains weight. The people like growing children, weightlifters, and pregnant women show positive energy balance and bulk up.
c) Negative energy balance: If the difference ends up in a negative number, a person achieves an imbalance required for weight loss. This is called energy deficit and the person slims down due to the negative energy difference and loss of calories.
An active person uses more of its consumed energy to perform physical activities and hence would consume more calories to keep the body at its pace. Whereas, an inactive person do little or no physical activities and therefore requires less energy. As a result, he/she would consume fewer calories due to low energy requirements.

Migration
Answer:
The answer is migration
Explanation:
Migration occurs when a social group, whether human or animal, executes a transfer from its place of origin to another where it believes its quality of life will be renewed. That involves the setting of a new life, of a new, different social, political and economic environment. An example of this is the migration of people affected by the economic or political crisis, as is the case in Venezuela today.
