Answer: Homeostasis
Our body temperature stays constant no matter the changes that may occur in the outer environment - for example, a hot summer afternoon or a cold winter morning. This is an example of homeostasis
Explanation:
Homeostasis is the maintenance of a stable internal environment. Hence, the body maintains a stable temperature, ph level, water-salt balance etc, necessary for healthy development based on the effects of the hormonal and nervous systems.
No.... the weight of a substance is the mass of the substance multiplied with the acceleration due to gravity on it.
Answer:
A virus is a tiny infectious biological agent that can only replicate or duplicate inside the host cell. These infectious agents can infect all different types of living organisms ranging from animals and plants to microorganisms and archaea and bacteria.
Virions are ineffective particle or form of the virus outside of the host cell, with RNA or DNA and a protein capsid.
The main role of these infectious agent virions is to transfer the DNA or RNA genome from itself to the cell of host and expressed the gene which means produce proteins from the genome transferred to the host cell.
Answer:
Atrioventricular valves.
Explanation:
Heart is the muscular organ of the body and acts as the pumping organ of the body. Human heart is not bigger than the fist and the human heart is divided into four chambers.
Heart murmur may be defined as the swishing sound that are made during the blood flow. This represent the heart problem. The bicuspid valve of heart is atrioventricular valve. The damage in the atrioventricular valve causes the heart murmuring.
Thus, the answer is atrioventricular valves.
