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).

During the method of photosynthesis, daylight is employed to convert water and dioxide into aldohexose and gas. light-weight reactions convert the energy in daylight into the energy of ATP and NADPH.
a) In the bright daylight, the Calvin cycle happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are accustomed convert molecules of carbonic acid gas into high-energy sugars.
b)In the darkness, the Calvin cycle conjointly happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are used to convert molecules of CO2 into high-energy sugars.
c) <span>There will be a decrease </span>in the products ATP<span> and NADPH if the plants </span>are unbroken within the<span> dark for </span>a protracted<span> time </span>and also the<span> Calvin cycle </span>can't be continued.<span />
Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles. Please give me the brainliest answer?
:) Hoped this helped!!! Have a good day!!! <3
D; because the cells dna is not in the nucleus
