The gene EEF1 ALPHA1 supports cell theory. Cell theory states that all living things are made from cells. Since all living things share this gene that dates back to an organism that lived billions of years ago, it makes sense to conclude that all living things originated from the earliest forms of life. This conclusion would explain why all living things on Earth are made of cells.
Answer: Characteristics of viral particles from the options given are;
1. Parasitic obligate.
2. The centre layer is predominate protein.
3.Genome may be RNA exclusively.
The characteristics of living cells are:
1 . May have cell wall.
2. Contain ribosomes.
3. Always of plasma.
Explanation:
Living cells are the basic unit of life, that contain the fundamental molecules in which the living things are composed of. Living cells have plasma membrane, ribosomes, cytoplasm and DNA.
Viral particle is a structure or infectious agents that enter another cell and replicates itself in a living cell. The are obligates parasite, that have no cell wall, they have center layer of protein, the genome contain either DNA or RNA, they reproduce only in living cells, they lack cytoplasm and organelles.
ANSWER:
Cytokines, Chemokines, Leukocytes, Neutrophils, Macrophages, and Dendritic cells are all involved
EXPLANATION:
On the incidence of Streptococcus, the immune system activates a complex response that relies basically on the instatement and activation of macrophages, neutrophils, and dendritic cells.
These activities will only occur on the activation of innate immune responses through workout between pattern recognition receptors (PRRs) with streptococcus derived pathogen-associated molecular patterns (PAMPs).
Moreso, cytokines and chemokines (well known are IL-1β and CXCL1 respectively) produced by macrophages and dendritic cells on exposure to Streptococcus, elicits neutrophil.
Neutrophils then produces antimicrobial proteins, reactive oxygen species (ROS) and sometimes neutrophil extracellular traps (NETs), all these for the bacterial infection control.
