If you push ice together slowly after awhile the pressure from the ice being pushed together will make the ice crack and break.
The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms
The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.
<h3>
What was the conclusion of the meselson-stahl experiment?</h3>
Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.
1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).

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:
This is a word composed of two roots of Greek origin, the first (deinós), means “terrible” and the second (sauros), means lizard, so dinosaur means literally “giant lizard”. This term was invented in 1841 by Sir Richard Owen and was presented during an annual meeting of the British Association for the Progress of Science. The Dinosauria group originally grouped the three only known dinosaurs: Megalosaurus, Iguanodon and Hylaeosaurus, all from England.
Explanation:
The studies carried out by Richard Owen are so many and so extensive that they are practically unmentionable, however, if we speak of the term dinosaur, the work History of British Fossil Reptiles (History of British reptile fossils), dated 1849 .
In this work Richard Owen talks about the large group of reptiles that exercised total hegemony during the Mesozoic Era and named this group with the term Dinosauria, referring to the biological branching of these prehistoric animals.
The term "dinosaur" and "dinosauria" is mainly because Richard Owen studied three fossils that could not be identified with any other fossil or living animal, such was his astonishment that he decided to name these fossil remains as "terrible lizards."
