Probably the animal responsible for eating the oysters was the starfish, which are invertebrate marine animals that feed on molluscs such as oysters.
Starfish are echinoderms, have a central disc and about five arms, which give them a star appearance, justifying their name. They can be colored and their surface can be smooth or granular.
Their feeding occurs through a hydraulic system, they feed through the opening of the mouth and placing the stomach around the prey when feeding.
These animals are predators of invertebrates such as molluscs, crustaceans, sponges and corals.

Answer:
because the sympathetic nervous system is no longer active following strenuous exercise.
Explanation:
Answer:
Electron
Explanation:
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol= e-
Mass= 9.10938356×10-31 Kg
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.
Properties of cathode ray:
The ray is travel in straight line.
The cathode ray is independent of composition of cathode.
When electric field is applied cathode ray is deflected towards the positively charged plate.
Hence it was consist of negatively charged particles.
While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
I think it’s D. A large amount of humans.
And B. Temperatures of 5-10 degrees. I’m not sure sorry if it’s wrong.

<u>What's</u><u> the</u><u> </u><u>function</u><u> of</u><u> </u><u>RER </u>?
<h2><u>Answer</u><u>:</u><u>-</u></h2>
- RER helps in the formation of proteins in the cell. The presence of ribosomes is actually responsible for the synthesis of the proteins by the RER.
2. RER help in transport of protein which are synthesised by ribosomes on their surface.
