Host-pathogen interactions, emphasizing issues such as the host immune response upon infection, and the mechanism of pathogen transmission in the investigation and analysis of the different stages of infection.
<h3>Pathogen </h3>
The severity of the disease symptoms is referred to as virulence, and a pathogen is an organism that causes disease in its host. Pathogens are diverse in terms of taxonomy and include bacteria, viruses, and both single- and multicellular eukaryotes. Pathogens impact all living things, including bacteria, which are the target of specialist viruses called phages.
There are countless bacteria and viruses on the planet, and they live in virtually every environment. Over ten billion bacteria and one hundred billion viruses are generally present in one liter of surface seawater.

The answer is D. Most cells have a membrane but some dont
The answer is <span>B. Stratosphere </span>
The answer would be A: 1:16
This is because the letters mean:
Y: yellow
y: green
S: round
s: wrinkled
Thus, because the lowercase letters represent recessive alleles, both letters must be lowercase in order for the gene to show in the offspring.
So, if you wanted green, wrinkled, seeds, the only option (in letter form) would represented by:
ssyy
Therefore, because there is only one block with those letters, and sixteen blocks total, the ratio is 1:16.
B. Oncogenes. Protooncogenes usually mutate to form oncogenes, which codes for a growth factor that is permanently activated, which leads to excessive cell division.
Hope this helps! :)
