Fern spore germinates into prothallus.
Explanation:
Ferns are members of phylum pteridophyta, the vascular cryptogams.
These are first land plants which are known to have a distinct conducting system of xylem and phloem.
They reproduce by forming spores that germinates into a heart shaped gametophyte.
The gametophyte of the fern is called prothallus.
The heart shaped gametophyte has root like structure called rhizoids.
These rhizoids anchor the gametophyte to the substratum.
I dont get want you're trying to say
Since the statement clearly states that the salivary amylase is an enzyme that breaks down starch into maltose at 37C.
When the first test tube has been increased to about the same temperature as the control group then the salivary amylase enzyme will metabolise the starch into maltose. This process is influenced then by the temperature for the enzyme to initiate and execute the activity.
Answer: A variety of <u>microorganisms</u> can cause disease.

I believe that the examination of the ages at which children achieve motor milestones show that there are wide variations in the ages at which infants begin to sit, walk, and crawl. Developmental milestones are the skills such as taking the first step, smiling for the first time, and waving which vary differently from one child to another. Children reach milestones in how they play, learn, speak, act, and move. For example, between the ages of 9 to 12 months, children begin to achieve physical milestones such as standing up or even walking.
