Answer: Fever ( also termed as pyrexia) is a state of body in which internal body temperature rises substantially beyond the normal range of body temperature. It is commonly caused by the infection of pathogenic agents ( such as virus and bacteria) in the body.
It is a common way to fight against and eliminate the infection as it enhances the amount of anticancer and antiviral interferon in the blood, which do not allow the infectious agents to replicate. Apart from this, they are also temperature sensitive and therefore replication becomes difficult.
Thus, presence of a fever usually corresponds to stimulation of immune response of body to fight against the infectious agents.
B.meiosis
C.photosynthesis
D.mitosis
Answer:
The correct answer is A.respiration
Explanation:
Cellular respiration is a process which produces ATP (adenosine triphosphate) and methabolites. ATP is an "energy coin" which provides energy for biochemical processes in all cells. The other options are not correct: meiosis is the division process of sexual cells, mitosis is the division process of somatic cells and photosynthesis ocurrs in plant cells to obtain energy (not in animal cells of muscle tissue).
Answer:
It becomes a positive ion and its radius decreases
Explanation:
As per the Octet rule, Barium has 2 electrons in its outermost shell. When it loses the two electron it gains two positive charge i.e Ba2+. As the barium loses the two electron from its outermost shell, the outermost shell becomes vacant and thus is no more considered as a part of atomic geometry of the barium atom and since the outermost shell is considered negligible the radius of barium atom reduces automatically.
