	B.	Organelles
	C.	Enzymes
	D.	None of the above

28.An injured cell may commonly show which of the following changes?

	A.	Sodium and water diffuse into the cell, causing it to swell and sometimes to rupture
	B.	Fat droplets accumulate within the cytoplasm
	C.	Apotosis
	D.	A and B only
	E.	None of the above

Answer 1

14. Muscle cells

Neurons and Cardiac cells divide only in the embryo stage. When the baby comes out of the mother, neurons and Cardiac cells lose their ability to divide. In an adult individual, neurons and cardiocytes do not divide.

18. Glucose

Diabetes mellitus is a metabolic disorder characterized by high level of glucose in blood. This is because of insufficient levels of insulin. Insulin is a hormone which controls Glucose level.

19. All of the above

DNA is shared by brothers and sisters because we come from same parent or same grandparents. DNA is also shared between parents and children because children come from parents. Identical twins also share DNA and that too high percentage similarity is seen. This is because both of them come from same parents.

21. Cytoplasm

Organelles are the components of cell which perform different function inside the cell. They are suspended in a jelly like fluid of cell called cytoplasm.

22. Organelles

Organelles are part of cell which are present inside it. Each organelle perform a different function. Mitochondria perform cellular respiration and generate ATP, Golgi apparatus for package on transport molecules etc. Lysosomes are meant for digestion of cell debris and foreign substances.

28. Apoptosis

Apoptosis is programmed cell death. It is a normal process in the development of an organism. Some of the organs undergo apoptosis to mature into final structures. Infected cells also undergoes apoptosis so that the cell dies and the pathogen present in it does not provide to neighbouring cell.
