Antibodies have a variable region that binds to a specific antigenic determinant.
Antibody
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion).

#SPJ4
The stage where the doubling time will be the shortest will be the one where replication is taking place the fastest. This phase is known as the exponential phase. This phase is characterized by exponential growth rates of a bacterial colony.
This phase occurs due the excess amount of resources that are present compared to the amount necessary to sustain the bacterial colony. Therefore, not being limited by resources, the bacteria multiply rapidly. However, the resources then run out due to which replication stop, bringing on the lag phase. Finally, the bacteria begin to starve and die off due to the lack of resources, bringing about the death phase.
Answer:
Vestigial structures
Explanation:
support evolution, by suggesting us that the organism changed from using structure to not using structure or using it for another purpose.
You didn't put an image of the graph lol
False because light can come from natural resources and it doesn’t need materials it just needs to produce itself
