Answer:
Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid—either DNA or RNA—never both.
Explanation:
Living organisms are not created spontaneously.
Explanation:
The cell is the basic and fundamental unit of life. Cells are the basis of the organization of life and on it, complexity is built.
The cell theory was formulated around the 17th century and there are some of its postulates:

Answer:
In chronic hypertension the baroreceptors get used to high blood pressure and does not respond effeciently.
Explanation:
Hypertension is the condition when blood pressure usually remains higher than normal. The systolic higher blood pressure is considered high above from 139 (mmHg) and diastolic is considered as above from 89 (mmHg).
The condition is considered to be chronic when it affects vital organs such as lung and hurt. There are several stimuli to which brain response to maintain normal blood pressure. Most important and fast of these is baroreceptors present in blood vessels that detect the change in blood pressure and signal to brain for proper response such as dilating the blood vessels in case of high blood pressure.
In coronary hypertension the walls of blood vessels become stiffer due to several factors such as smoking, stress and ageing. The high blood pressure produces tension in the wall of artery which is detected by baroreceptor. In coronary hypertension these barorecepetors get used to higher blood pressure thus does not response to it properly. So blood pressure remains high.
