I hope this helps you! Good luck :)
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.
The name of chemicals that are secreted by glands into the blood and those that affect organs elsewhere in the body are known as Hormones.
<h3>What is Gland?</h3>
A Gland may be defined as an organ in the human or animal body that perspires certain chemical substances for usefulness in the body or for liberation into the surroundings.
The endocrine glands are responsible for the synthesis of such chemical substances into specific body parts and organs and pass them directly into the bloodstream. These chemical messengers are thought to be the agents of communication between one body part and another.
Therefore, it is well described above.

<span>This is a positive feedback. These episodes make the next glacial period even more severe and long-lasting than the one prior. This is due to the reflectance of the surface of the land having a positive relationship with how much energy is absorbed: as the reflectance increases, absorption decreases, and the glacial period increases in severity.</span>
