Answer:
nitrogen fixing bacteria
these organisms obtain nitrogen, Nitrogen fixing bacteria convert nitrogen from the air into ammonia and animals ingest the ammonia.
what are the role of nitrogen fixing bacteria ?
Nitrogen fixation occur by a bacteria called nitrogen fixing bacteria during nitrogen cycle.
nitrogen-fixing bacteria are the microorganisms that provide plants with the vital nutrients and it can't be obtained from the atmosphere (air).
nitrogen-fixing bacteria are responsible for the conversion of atmospheric nitrogen to ammonia during nitrogen cycle can be taken up by plants.

Study this unusual food chain. What could ‘P’ represent?
a. Any normal insect that eats grains.
b. An insect that can make its own food.
c. A carnivorous plant like the Venus flytrap.
d. There is a mistake - nothing can match 'P'.
The correct option as to what P could represent in the food chain would be option C.
P could be a carnivorous plant such as Venus flytrap because these plants are able to get their food both by harnessing solar energy to photosynthesize and by feeding on flying insects.
On the other hand, P cannot be any normal insect that eats grains or makes its own food because according to the diagram, P also derives energy from the sun. Only plants and some microbes are able to photosynthesize.
Therefore, only a carnivorous plant is able to both photosynthesize and feed on insects for their foods when necessary and hence, can fill the space of P in the food chain.

How do sediments eroded by water become more smooth and round
Answer: Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment causing it to become more round and smooth.
I hope this helps!
Answer:
through friction.
Explanation:
The sediments rub together to become smoother. Sediments that are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round.

HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.
B: Proteins' tertiary structure is dictated by R group bonds.
C: Proteins have quaternary structure when they are arranged together.
The statement that is not true related to the protein structure is option b. Proteins' tertiary structure is dictated by R group bonds.
What is protein structure?It is classified as the three dimensional shape of the protein.
In the tertiary structure it does contain the single polypeptide chain that we called as the backbone or there more than one protein secondary structures
Also, it should not be dictated by R group bonds.
Therefore, we can conclude that the option b is correct.

why are casts, molds, and trace fossils so common?
Answer:
Cast fossils occur when mold fossils are filled in with minerals that harden over time, creating a fossilized replica of the original organism. Water seeps through the rock surrounding the mold fossil, leaving behind minerals which fill the mold. Any mold fossil can potentially form a cast mold.
