Answer:

Down's syndrome

Explanation:

Down's syndrome is caused by trisomy of chromosome 21. Trisomy refers to the presence of three copies of one chromosome in the genome. Since David has extra genetic material in chromosome 21, he is suffering from Down's syndrome.

Down's syndrome would affect the mental development and learning process of David. He is likely to have a broad skull with a small mouth.

Luda [366]

Answer:

1. sympathetic

2. parasympathetic

Explanation:

The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.  

Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.

Glucose moves from the plasma into a skeletal muscle cell, where it is used for energy. Through which fluid compartment does glu
Tanzania [10]

Answer:

(B) Interstitial fluid

Explanation:

The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.
