Explanation:
A molecular clock determines evolutionary relatedness by examining how many mutations or random changes in DNA, there are between two organisms. When we map the relatedness of different organisms, we are creating a phylogenetic tree. At some point, all organisms that are alive today shared a common ancestor.
Energy from ATP causes a transport protein to change shape, binding substances on one <span>side of the membrane, and releasing them on the other.</span>
Muscle cramps, fatigue, headaches, decreased ability to excrete toxins/waste from the body or carry nutrients throughout the body dryness, wrinkles, etc
Answer:
Because they can only reproduce in a living cell
Explanation:
Virus is an organism that is incapable of replicating on its own without a living host. A virus infects a living host and makes use of Its replicational ability to produce new virions. A virus consists of a genetic material surrounded by a Protein called CAPSID. It does not possess the characteristics of other living organisms.
This means that it does not carry out any of the features a living cell undergoes e.g reproduction, respiration etc. Due to this reason, it is not classified as a living thing. They don't possess organnelles that carry out this peculiar functions.
A virus is considered a peculiar microorganism because it can only live and reproduce in a living host cell.
Bacteria may affect plants in a number of ways. Diseases have been mentioned, but most bacteria co-exist with plants quite easily. Several bacteria are involved with the transitions of nutrients and make nutrients such as nitrogen plant available (the plant is only able to absorb some nutrients in certain molecular forms). While other bacteria convert nutrients and toxins into forms unavailable to the plant.
Other bacteria make Some bacteria, Rhizobia in particular, develop symbiotic relationships with some plants. Rhizobia convert atmospheric nitrogen into ammonium which is plant available. In exchange, the plant provides Rhizobia with shelter (a root nodule) and food (photosynthates).
