Answer:B
Explanation:bc all of the other ones was equal together and the concentration gradient could not spread them
Solution:
The difference between them are:
The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,
The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.
This is the required answer.
A food chain is a linear representation of the energy going through organisms while a food web shows multiple connections between the organisms.
It would be considered biotic since it is nonliving

<h3>
What is Genotype?</h3>
An organism's genotype is made up of all of its genetic components. The alleles or variations that a person holds in a specific gene or genetic region are also referred to as the genotype.
The amount of copies of each chromosomes found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two different alleles for each gene. Homozygous refers to a genotype where both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.
Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.
