Hello! Here are a couple of major events that happened in the Mesozoic Era.
1. The Mesozoic Era began with the largest mass extinction in history, killing off the vast majority of marine and terrestrial life on Earth.
2. After that mass extinction, the super continent Pangaea began to break off, and the dinosaurs began to flourish the Earth, although they were killed off at the end of the Mesozoic Era.

Answer:
Life Cycle of Viruses with Animal Hosts Lytic animal viruses follow similar infection stages to bacteriophages: attachment, penetration, biosynthesis, maturation, and release (see Figure 4). However, the mechanisms of penetration, nucleic-acid biosynthesis, and release differ between bacterial and animal viruses.
Explanation:
Answer:
Chemically gated Na+-K+ channels
Explanation:
The acetylcholine receptors are the receptors or ion channel proteins which are considered the transmembrane proteins. The acetylcholine receptors are of two types depending on the ligand which binds that is either nicotinic or either muscarinic receptors.
When the acetylcholine binds the receptor molecule, the ion channels open up and allows the passage of the sodium and potassium ios which depolarizes the membrane potential and generates the action potential in the neuron.
Thus, Chemically gated Na+-K+ channels is correct.
