Apical surface is the name of the epithelial cell surface that faces the outside of an organ.
The edge of the epithelium that faces light or the outside environment is called the apical surface.
The apical surface of the epithelial cells, where the lumen of the vesicles and tubules are located, and the inner surface of the body cavities, form the interface between the extracellular and underlying tissues.
It has multiple functions, including absorption and excretion, immune surveillance, sensory conduction, and barrier formation.
These functions are activated by several specializations, including glycocalyx (it cushions and hydrates the apical membrane), apical plasma membrane lipids(it restricts flow of water and solutes), channels and receptors (it regulates active and passive transport and sense the presence of growth factors), cytokines, and mechanical stimuli (eg, tensile and shear stress).

Answer:
Slow twitch fibers have more mitochondria because they aerobic oxidation basically oxidative phosphorylation to resist muscle fatigue by generation of ATP molecules.
Explanation:
Slow twitch fibers are also called red muscle fibers that contain large amount of mitochondria and Myoglobin pigment which gives them red coloration.
Slow twitch fibers uses oxygen to carry out oxidative phosphorylation of aerobic respiration to generate energy rich compound called adenosine tri phosphate or ATP.Thus the slow twitch muscle fibers can resist muscle fatigue.
That"s why slow twitch muscle contain more mitochondria
As their contents are used for energy during weight loss, fat cells get smaller in size, but their overall number doesn't change.
<h3>Where Does Fat Go When Weight Is Lost?</h3>
- Fats are liberated from fat cells and transferred to the mitochondria, the energy-producing organelles in your body's cells, by sustaining a steady calorie deficit. Here, a number of procedures break down the fat to create energy.
- These same cells may become smaller when you lose fat, yet they continue to exist in roughly the same numbers. Therefore, fewer fat cells, not more, are the main cause of changes in body form.
- Also implied by this is that even when you lose weight, fat cells are still present and can readily regain their original size if efforts are not made to keep the weight off.

A
Explanation:
water expands as it goes from liquid to solid. When the temperature is warm, water works its way into cracks in rock. When the temperature cools below freezing, the water turns to ice and expands. The ice takes up more space.
