Answer:

Scenario I, Scenario II, and Scenario III are examples of competitive networks.

Explanation:

There are different examples of nets as interactions between species. Trophic net is a very common example of these interactions. Another one is the competitive network.

The competitive network refers to the competition for the same resource between different species in a community or ecosystem. When a resource is useful for two or more species, they compete to gain it.

The competitive network can be represented as arrows that indicate which is the dominant species over the other. This representation must be done with a<u> minimum of two species interacting</u> and indicating through the direction of the arrow, which species wins the competition.

There is a competitive hierarchy when there are more than two species, for example, species A, B, and C. Species A dominates over the other two, and species B dominates over species C. In these cases, the representation would be A --> B --> C. This reflects a transitive competitive network. Species A displaces species B and C, and species B displaces species C. The only species that can persist is A. This example can be extended to <u>any number of species</u>, which suggests that a hierarchy network does not promote biologic diversity.

Answer:

heart, get rid of toxins/flush out toxins

Explanation:

Project Renew:

Project Renew is an ECP (external counter pulsation) brand developed by Innovations Ventures LLC which is owned by Manoj Bhargava, a businessman and philanthropist.
External counter pulsation is a device that pumps blood from the legs to the core body while the heart rests. Therefore, this device acts like an auxiliary heart. It provides the heart a chance to rest, thus, reducing its work load.
The idea behind project renew is not only to aid circulation but to ensure proper excretion of toxins from the blood. An auxiliary circulation system would ultimately lead to a better detoxification system.

Indicate weather the label identifies an adaptive or innate form of defense

suter [353]

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.
