Answer:
Vector
Explanation:
<u>Diseases can be transmitted by the mechanical or the biological vector. Vector is an animal (typically can be called as an arthropod) which carries disease from one host to another. </u>
Mechanical transmission is the one in which an animal which carries the pathogen from on host body to the another without being infected by it. It is facilitated by the mechanical vector.
Biological transmission is th eone which occurs when pathogen reproduces within the biological vector which transmits pathogen from one host body to the another.
Answer:
Electrolytes are nothing but minerals that have electric charge when it is mixed in liquid like blood. thus the sodium and potassium electrolytes will help regulate the nerve and muscle function. They also maintain the acid-base balance by regulating the electric charge on the cells and water flow across the membrane.
Explanation:
Answer:
B. The biomass of leaf litter in the bags will be greater in leaves with higher lignin content after the same length of time.
Explanation:
Lignin is a major, one of the most slowly decomposing components of dead vegetation, including leaf litters. The lignin content has been found to have a high correlation with litter decomposition.
<em>Hence, at the end of the experiment, the litter bag containing leaf litters with higher lignin contents will be expected to weigh more than those with lower lignin contents.</em>
The correct option is B.
