Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomy
DaniilM [7]

Answer:

Deuteromycotes

Explanation:

Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.

Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.

However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.

Activation of the sympathetic nervous system A. increases salivation and increases blood pressure. B. decreases salivation and i
yaroslaw [1]

Answer:

B. decreases salivation and increases blood pressure

Explanation:

The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.

The sympathetic nervous system  is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.

Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.

The control of salivary production by the sympathetic nervous system  leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.
