NAD is the electron carrier which is used in redox reactions in cellular respiration
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:
b) natural variation w/in a species
Explanation:
All the answer you put are evidence of evolution also I have done this before.
Answer:
A: Oxygen is a process by which respiration happens.
Explanation:
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Also:Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
