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.

Answer:
B - Python predation has caused a trophic cascade that changed the mosquitoes' niche.
Explanation:
The passage infers that the predation by the Burmese pythons has reduced the population of the animals in Southern Florida thus making the Culex cedecei mosquito to have a reduced number of options to feed from.

Summarily, the passage is saying that the invasion by the Burmese python has changed the niche of most animals including the mosquitoes in the Southern Florida's wild.
1. flask-shaped gland unbranched ducts=SIMPLE ALVEOLAR GLAND
2. slender, straight gland unbranched ducts = SIMPLE TUBULAR GLAND
3. combination of gland shapes = TUBULAR ALVEOLAR
4.branched ducts=COMPOUND GLAND (salivary glands)
All of them are the exocrine glands (their product is secreted on the epithelial surface).
