Allele is not the name of a classification level because its not a part of taxonomical hierarchy. Therefore, option (A) is correct.
Taxonomic rank is the relative level of a group of organisms, known as a taxon, within an ancestral or hereditary hierarchy. This term is used in the field of biological categorization.
The Linnean system is the foundation for the modern method of classification, which consists of eight different levels of taxa. These levels, which are listed from most general to most specific, are as follows: domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.

Explanation: I took the test with these answer and got A correct
Answer:
Different combinations between these four set of chemicals
Explanation:
There can be billions of combinations between the four chemicals of DNA. The four set of chemicals i.e nucleotide (generally referred to as bases) namely -
A- Adenine
T- Thymine
C - Cytosine
G - Guanine
These nucleotide form codon i.e set of three nucleotide and form chain structure which can be long up to any extent.
Codon example - ATC TGA
Thus, variation in combination of four nucleotide and ability to form long chain of codon allows DNA to have several forms and variations
Bacteria would enter the body and inhibit a specific immune response.
Microorganisms would release histamine, causing inflammation and swelling.
Infectious agents would prevent the immune system from producing lymphocytes.
Pathogens would invade the body and cause disease, such as giardia.
Answer: Pathogens would invade the body and cause disease, such as giardia.
Explanation:
The water body get polluted by the disposal of biological and non-biological wastes liberated by the human society so as to get rid of those wastes. The biological wastes includes the slurry of sewage which mainly includes the human and animal fecal matter which includes the pathogens which colonize and deteriorates the quality of water.
If the water from such water body if taken for the purpose of drinking, cooking and other crucial activities will likely to introduce the pathogens into the human body which invade the human immune system and can cause deadly diseases such as giardia.
b. vagina.
c. fallopian tube.
d. ovary.
Fertilization in humans, which is the union of an egg and a sperm, mostly occurs in the fallopian tube. The egg, after being released from the ovary during ovulation, travels down the fallopian tube where fertilization by a sperm can occur.
The fertilization of the human egg typically occurs in the fallopian tube, which is option c. This process is part of the reproductive cycle where the egg, released from the ovary during ovulation, travels down the fallopian tube. At the same time, sperm, after ejaculation, travels from the vagina through the uterus to meet the egg in the fallopian tube. If a sperm successfully penetrates the egg, fertilization occurs, resulting in a zygote which will eventually travel to the uterus for implantation. Hence, the fertilization site is typically the fallopian tube, not the uterus, vagina, or ovary.
