Answer:
Active transport; Passive transport; Passive transport
Explanation:
When concentration of a substance is different on either side of a semi-permeable membrane, the movement of this substance can occur by active or passive transport. Active transport occurs when the substance is moved from the region of its lower concentration to that of its higher concentration. This type of movement uses the energy to move the substance. Since the glucose concentration is higher in the epithelial cells than in the food, it will enter into the cells by the process of active transport.
The passive movement of substances is driven by concentration gradient. The glucose concentration is lower in extracellular space than epithelial cells, so glucose will be transported into the extracellular space by passive movement.
Likewise, a higher concentration of glucose in extracellular space than blood will move it passively into the bloodstream.

Answer to your question is D
Answer:
1. Cervical
2. Lumbar
Explanation:
Spinal enlargements are the conspicuous regions in the spinal cord from where spinal nerves to and from limbs exit and enter respectively. Cervical enlargement is also called the superior enlargement. It starts from C4, the fourth cervical vertebra and extends to T1, the first thoracic vertebra. Cervical enlargement is the site from there the nerve that supplies to and come from the upper limbs arise.
Another enlargement is the lumbar enlargement. It is also called inferior enlargement or lumbosacral enlargement and extends from the ninth to the twelfth thoracic vertebra. It is the site from where the nerves to and from the lower limbs arise.
Answer:
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.
