<u>Gymnosperms and Angiosperms-</u>
Gymnosperms and angiosperms evolved seeds and pollen grains allowing them to live and reproduce in drier habitats than bryophytes and seedless vascular plants.
<u>Properties of gymnosperms and angiosperms-</u>
Gymnosperms are plants which bear seeds without fruits or without any outer coverings. These plants also do not produce flowers. Most plants under this group have needle-shaped leaves. This is an adaptation as these plants grow in colder conditions. Gymnosperms. These plants produce pollen without bearing flowers. Angiosperms are found in almost all climatic conditions. These plants bear flowers and produce seeds that are enclosed inside a fruit or inside an ovary. The seeds of angiosperms have a single cotyledon.

Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.
The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.
When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.

Answer:
The correct answer is - Protein molecule.
Explanation:
The cell membrane is the outer membrane of the cell that differentiates the external environment from the internal components of the cell. The cell membrane is made up of two major components that are lipids and proteins.
Proteins are present as channels and in the form of membrane proteins in between the lipid bilayer. Protein is the molecule that denatured or destroyed at high temperatures such as 70 degrees.
Dna contains sulfur and little phosphorus
