<u>Answer</u>:
The skull of a bird looks similar to that of a young dinosaur when they are at their embryo stage.
<u>Explanation</u>:
Bird's skull at their embryo stage looks like young dinosaur's skull. This feature gives evidence of their evolution and their ancestors. The surviving member of the feathered dinosaur family are the birds. The unique skull shape of a bird shaped like a beaker with a dome like cranial resembles with the non-flying ancient dinosaurs. This phenomenon is often named as psuedomorphism. In this phenomenon, these features of the ancestor at its embryo stage is retained by its predecessors.
B, Magnitude of past earthquakes in the area
Answer:
Acetylcholinesterase enzyme inhibitors are limiting the hydrolysis process of the neurotransmitter acetylcholine, increasing its availability and interaction with specific receptors.
Explanation:
Acetylcholine is a neurotransmitter that aims to stimulate or inhibit the activity of a tissue, by stimulating nicotinic and muscarinic receptors. An example of this is the action of acetylcholine on nicotinic receptors present in the muscle, which promote muscle contraction.
Acetylcholinesterase is responsible for hydrolyzing acetylcholine to make the effect on a receptor end.
In degenerative diseases of the nervous system -such as Alzheimer's- the activity of acetylcholine decreases, so reversible acetylcholinesterase inhibitors are used to limit the neurotransmitter hydrolysis process, increase its bioavailability, and allow the effect of acetylcholine on muscarinic brain receptors.

Answer:
messenger RNA (mRNA)
Explanation:
mRNA or messenger RNA is one of the three types of RNA molecules (the other being tRNA and rRNA) that is specifically responsible for carrying genetic information previously encoded and stored in the DNA into the ribosomes for translation to occur.
The process of translation results to the synthesis of amino acid sequences, which make up a polypeptide. Hence, it can be said that mRNA is that type of RNA that acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain.
Photosynthesis is a vital source of energy for nearly all living organisms, not just plants. ... It converts carbon dioxide in the atmosphere into organic compounds like sugar, providing the world with an energy source that is transferred to other organisms.
