Answer: <u>Option C, they digest pathogens</u>
Explanation: Monocytes are involved in the process of digesting pathogens and infected cells, termed as phagocytosis.
Monocytes don't produce antibodies, only B cells can produce antibodies. So, option A and D are incorrect. Also they appear colorless when observed under the microscope. They don't appear granular, so option B is also incorrect.
Answer:
b. The two bacterial strains have different phenotypes.
Explanation:
In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.
Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.
Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.
Yes every time of you did not know
There is no context so I will just explain what a constant is:
In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment.
An example would be:
If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.
The amount of ATP (Adenosine Triphosphate) produces is a characteristic that would best describe or distinguish glycolysis and the Krebs cycle from the electron transport chain.
