Certain kinds of shells are always found in rock layers lower than layers with plant fossils. Dinosaur fossils show up only in layers above or with plant fossils. What does this tell you about when these organisms lived?
Answer:
this shows that at one point these animals lived on the surface because there were plants for them to eat
Explanation:
Hope this helps you out!!!
If so please give brainliest <3
Because there were plants for them to consume, this demonstrates that these creatures formerly lived on the surface.
What were dinosaurs?The term "dinosaur" refers to a clade of reptiles that lived globally for approximately 180 million years and first emerged about 245 million years ago, at the start of the Middle Triassic Epoch. These reptiles were frequently quite enormous. Many lines of evidence currently indicate that one branch developed into birds around 155 million years ago, but the majority of them perished before the end of the Cretaceous Period, or approximately 66 million years ago.
The term "Dinosauria," which was first used to describe a small number of fragmentary specimens, is today used to refer to more than 800 generic names and at least 1,000 species, with additional names being added to the list each year as a consequence of international scientific research.
However, not all of these names correspond to actual taxa. Many of them were constructed using shattered or partial information that might have originated from two or more separate dinosaurs. Additionally, bones that are not actually from dinosaurs have occasionally been mistakenly classified as dinosaurian.
The number of dinosaurian species is believed to be 10–25 percent of the total historical variety, however, dinosaurs are well recorded by the numerous fossil remains found on every continent of the planet.
Therefore, this demonstrates that these creatures formerly resided on the surface because there were plants for them to consume.

You have learned about the ways viruses can disrupt human health and ecosystems. Can viruses also be helpful? Justify your answer.
Answer:
Bacteriophages are specialised viruses that only infect bacteria. Recently, bacteriophages have been tested on a patients in a critical condition. A patient was suffering from a bacterial infection in their chest cavity and the species of bacteria are naturally resistant to antibiotics and can even survive in alcoholic hand gel. The patient had no other hope left. So a few thousand bacteriophages were inserted in their chest cavity. After a few weeks the infection had completely disappeared.

Bacteria use ________ to break down hydrocarbons during bioremediation, just as humans use them to digest food.
Answer:

What can be done to reduce the production of carbon dioxide?.
Answer:
Probably not much.
We exhale carbon dioxide every second.
"Burn less trees." - thank you kaliliew16
Therefore, not much can be done.. We would have to all stop breathing to stop the flow of carbon dioxide, meaning we'd all die off quickly due to lack of oxygen.
hope it helps you!
Less wood could be burned, and it's leafs along with it, since they're both plants, and plants take in carbon and release oxygen, if they are burned they'll release all the carbon they stored, coal, oil, and natural gas contain carbon too, so in order to the reduce the production of carbon dioxide, we'd have to stop burning all of these less and less.
