Answer:
According to what has been investigated the option that should be supported by more scientific evidence: In psoriasis plaques, there are fewer T-cell clones, but there are often a large number of T-cells representing only a small number of clones (this is called oligoclonal expansion).
Explanation:
Oligoclonal expansion does not occur only in this pathology, it also occurs in other recurrent diseases such as multiple sclerosis, this phenomenon is widely studied and little discovered in some aspects and is mainly based on both tcd4 and tcd8 and b lymphocytes.
In this case, the presence of ltcd4 in psoriasis is very versatile and depends on the patient's immune response, which is why more scientific evidence is needed on this topic, based mostly on meta-analyzes.

Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color.

An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.
Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.
Answer:
reagin type antibody.
Explanation:
The rapid plasma reagin test is a test used to diagnose syphilis.
Syphilis is a sexually transmitted disease which is caused by treponema pallidum.
The rapid plasma reagin test is not for measuring the antibodies against actual bacteria but for measuring the antibodies formation due to material released because of tissues damaged by treponema pallidum like IgG and IgM against lipodial materials which is released from damaged cells.
