The answer is b. the germ theory of disease.
Louis Pasteur proposed that some diseases are caused by germs in the XIX century.
The concept of atomic weight was proposed by John Dalton. Benjamin Franklin proposed a simple theory of electricity, which was later compounded by Charles du Fay. The theory of evolution was proposed by Charles Darwin.
Answer:
Cytokines made by other innate cells, such as macrophages or dendritic cells
Explanation:
Innate Pattern Recognition Receptors (PRRs) on Dendritic cells and macrophages sense and respond to PAMPs and produce cytokines. Cytokines start the innate immune response.
The cytokines are produced in response to pathogen-associated molecular patterns (PAMPs) such as peptidoglycan monomers or CpG sequences on bacterial and viral genomes. Cytokines produced in response to pathogen receptors on cell surfaces, such as the inflammatory cytokines IL-1, IL-6, IL-8, and TNF-alpha, chemokines and type I interferons that act on leukocytes so as to promote and control early inflammatory responses.
Answer:
The correct option for the phenotypic ratio in this case is the following
9 : 6 : 1
Explanation:
In order to calculate the ratio, divide the two larger numbers each by the smallest one - which here would be 17.
So, 147 ÷ 17 = 8.7 (rounded off to 9)
And 93 ÷ 17 = 5.6 (rounded off to 6)
This way, '17' is considered as 1. Hence,
Gold : silver : bronze
9 : 6 : 1
Nucleus, because that is where the genetic material is stored.
