I believe all of them change during cellular differentiation.
Resting can be a lot of things but i'm going to assume most of it is sitting.
sitting burns an estimated 75
calories per hour, but depends on your body composition, weight and metabolism.
To determine the number of calories burned in 24 hours of sitting, you need to multiply those 75 calories by the number of hours.
24 x 75= 1800
You would burn 1800 calories.
The resting metabolic rate is the amount of energy (calories) required by the body to function at the resting state. This measurement has into account basic metabolic activities, including energy (calories) used to eat.
The resting metabolic rate includes different metabolic activities:
- breathing
- circulation of blood
- organ functioning (e.g., digesting food)
- basic neurological functions
- The resting metabolic rate of the metabolism is measured in strict and steady (resting) conditions.
- On the other hand, the basal metabolic rate measures the minimum amount of energy (i.e., calories) required to perform the most basic life-sustaining functions.

Answer:
Many cells are specialised. They have structures that are adapted for their function. For example, muscle cells bring parts of the body closer together. They contain protein fibres that can contract when energy is available, making the cells shorter.
Answer:
A. synthesis of vitamin C.
Explanation:
Integumentary system refers to the skin and its appendages. So it doesn't have the role to synthesis vitamin C, but it can synthesis vitamin D through exposure to UV light. The major role of integumentary system is protective role (immuno defense-from infections, dehydration, temperature changes, protection of underlying tissue etc). It also contains many receptors (for pain, touch, temperature change) that detect environmental changes.
