Answer:
Two or more elements,
Two or more elements,Chemically combined elements,
Two or more elements,Chemically combined elements,More and definite proportions.
Explanation:
A compoundcan be definedas a substance which is composed of two or more elements, that are combined together chemically.
These constituents elements are present in definite proportion and quantities. The composing elements of a compound can be separated only by the means of chemical procedures. A compound is composed of more than one type of atom.
Hence answer could be:
Two or more elements,
Two or more elements,Chemically combined elements,
Two or more elements,Chemically combined elements,More and definite proportions.
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.
All cells have a protective covering known as cell membrane. In plants, the cell membrane is further protected by another layer called cell wall. All the organelles present inside the cells are membrane bounded structure.
Cell membranes are made up of phospholipid bilayer with extrinsic and intrinsic proteins. From the studies on the plasma membrane structure, it was found that the protein fingerprint of MITOCHONDRIA and CHLOROPLAST are most similar to the cell membrane.
Oceanic-continental convergence occurs when an oceanic plate and a continental plate converge. They are pushed together and the oceanic plate is forced to go under the continental plate. So based on the diagram, this convergence occurred in letter B.
Oceanic-oceanic convergence occurs when two oceanic plates collide into one another. The oceanic plate that is older, denser and/or colder will be the plate that will go under the other. It will be forced down into the mantle. So in our diagram, this occurs in letter A.
Continental-continental convergence occurs when two continental plates converge. In this case, the plates push up against each other and create mountain ranges. Unlike the other two, they do not sink down, the movement is upwards. This occurs in the area C of your diagram.
