Innate: keratinized epithelium
stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )
Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.
Adaptive: immunoglobulin plasma cells agglutinin
helper t cells memory t cells cytotoxic t cells cd4+cells
t lymphocytes
Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.
The answer is Negative charges on phosphate groups repel each other. The oxygen groups of a phosphoanhydride in ATP have electron cloud that repels each other. On hydrolysis, once a phosphate is lost, the electrostatic repulsion is reduced.
When ATP is hydrolyzed, it forms more hydrogen bonds with surrounding water molecules that when ATP is unhydrolyzed. Therefore, more energy is released since more bonds are formed than are broken. The net delta G is positive during hydrolysis of ATP.
If a scientist wanted to compare the exact number of organisms at each trophic level within a desert ecosystem, the pyramid he or she would use would be the pyramid of numbers. The pyramid of numbers presents the population of organisms (individually) in each trophic level in a certain ecosystem.
A. because you can't observe an animal in its natural habitat if you take it out of its habitat or if you have a model.
