Answer: diabetes mellitus
Explanation:
This is a disease condition associated with elevated blood glucose levels.
It is due to abnormalities of the Pancreas. The pancreas coordinates two hormones INSULIN AND GLUCAGON in its cells.
INSULIN converts excess sugar to GLYCOGEN while GLUCAGON breaks down GLYCOGEN to sugar when blood glucose/glucose levels drops.
If the pancreas beta-cells of glucose are faulty, INSULIN fails to converts excess glucose to glycogen; therefore glucose builds up in the blood plasma,and failed to enter the needed cells. Large amount of glucose is wasted in urine.This is diabetes Mellitus.
The two types of diabetes are:
Type 1 and Type 2.
Teeth helps to make the food into small particles.Without make them small we can’t digest them and swallow properly.
Hence teeth is essential for digestion.This process takes in mouth.
Answer
A. centrioles
higher plant cells do not have centrioles in cell division.
Answer:
B) neurons have stable, relatively unchanging internal environments.
Explanation:
Rough endoplasmic reticulum (RER) is studded with ribosomes which in turn serve as the site for protein synthesis. A cell with an extensive network of rough endoplasmic reticulum has higher rates of protein synthesis. Mitochondria are the powerhouse of cells and serve as the site for aerobic cellular respiration. A large number of ATP molecules are produced in mitochondria. Therefore, a cell with relatively many mitochondria appears to have a higher demand for ATP and higher consumption of oxygen.
A cell with higher rates of consumption of ATP and protein synthesis should be functionally active. The charge across the membrane and the internal concentration of ions such as Na+, K+ of a neuron keep on changing during the conduction of nerve impulse. Therefore, the presence of many mitochondria and RER does not indicate that the neurons maintain relatively constant internal conditions.
