Synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons is called Hebbian Synapse.
<h3>What is Synapse?</h3>
A synapse is a component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the target effector cell.
The transfer of nerve impulses from one neuron to another requires synapses.
The synapse contributes to the development of memory. Because of the signaling mechanisms of the receptors, which are activated by neurotransmitters across the synaptic cleft, the connection between the two neurons is strengthened when both neurons are engaged at the same time. The capacity of two interconnected brain circuits is thought to influence how well memories are stored. Long-term potentiation is the name for this process of synapse strengthening.

Catabolic reactions use energy to synthesize large molecules from small molecules.
<h3>What is a catabolic reaction?</h3>
The Catabolic reaction is the action of the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions. Catabolic reactions are a type of metabolic reaction that takes place within a cell. An example of a catabolic reaction is the process of food digestion, where different enzymes break down food particles, so they can be absorbed by the small intestine.

Upper epidermis. The cuticle on upper epidrrmal layer prevents excessive water loss
Answer: mucilaginous sheath
Explanation:
Helloyo!
Massive Star
They are typically greater then 8 molar masses. They typically have a quick main sequence phase, a short red supergiant phase and a death of a spectacular Cosmic event: Supernova. From there they can either become Neutron Stars or Black Holes
Medium-Sized Star
They usually have a Normal Main Sequence phase (Billions of years). From there they bevome Red Giants and expell their mass in a planetary nebula. From there they shrink and become white dwarfs first, then black dwarfs.
Hope it helps ya
...though astronomy is actually physics btw...
