Answer:
Well apples have seeds and mosses have spores. Spores are more abundant but are less likely to reproduce because they have no nutrient or water stores or protection like seeds do. Seeds are more likely to germinate into a plant because they have everything they need within the seed casing.
The endoplasmic reticulum is the term which describes an extensive network of tubes, sacs, and vesicles throughout a cell that provides transport as its main function. The endoplasmic reticulum is a small organelle and is found in most Eukaryotic cells. It is not found in red blood cells. The endoplasmic reticulum is a network in the core of the cell and occurs within the nuclear membrane and is involved in the synthesis of lipids and proteins. The endoplasmic reticulum also usually has ribosomes attached to.
this is kinda a fun topic.

Ertrodotoxin is a type of neurotoxin, and is produced by many fishes including, pufferfish, triggerfish, oceansunfish and porcupine fish. It is also produced by bacteria like Pseudomonas, and Vibrio. The toxin blocks the action potential of the neurons, and inhibit working of the nervous system
<h2>GPCRs,RTKs</h2>
Explanation:
G Protein Coupled Receptors(GPCRs) are more common and found in almost all eukaryotes whereas Receptor Tyrosine Kinases(RTKs) are second largest family of receptors that relay signal from cell surface to the interior
- G protein coupled receptors(GPCRs) interacts with the ligand activated GPCR and phosphorylates its intracellular domain.This process of phosphorylation can terminate signal or desensitize receptor
- Autophosphorylation of receptor can initiate signal in case of Receptor Tyrosine Kinases(RTKs);Autophosphorylation is a feature of RTKs in which receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase
- Seven transmembrane helices can be seen in case of G protein-coupled receptors(GPCRs);transmembrane protein of it consists of single polypeptide and spans the membrane 7 times
- Insulin receptor is a part of Insulin Signalling which comes under RTKs;Insulin receptor always exist in case of dimeric form
- Epinephrine receptor is an example of GPCRs;Epinephrine is an endocrine hormones produced in stress condition
- Transmembrane protein of GPCR activates G protein,activated G protein binds with effector enzyme and activate it;effector enzyme further can produce or destroy secondary messenger
