Nitrogen in the atmosphere exists in the form of _____.
NO2
NO3-
NH4+
N2
NH3
Answer:
N2
Explanation:
Although the atmosphere is mostly made up of nitrogen, it is in the form of a gas known as dinitrogen N2. Plants cannot use this form. Dinitrogen, or atmospheric nitrogen, can also be found in the soil. In addition to dinitrogen, other inorganic and organic forms exist in the soil as well.
Where do the most powerful earthquakes on Earth occur?
Answer:
Most earthquakes happen at or near the boundaries between Earth's tectonic plates
Explanation:
because that's where there is usually a large concentration of faults. Some faults crack through the Earth because of the stress and strain of the moving plates.
If you don't know where the tectonic plates are there is a lot of maps out there :>
theres these platetechtonics at the bottom of some places at earth, but i dont know where.
Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

which two products are bromelain likely to produce when breaking down proteins
amino acids
fatty acid
monosaccharides
nucleic acid
polypeptides
disaccharides
The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.
What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.
In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

If energy is released, free energy must be what?
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.
Explanation:
Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?
A.silent
B.missense
C.nonsense
D.insertion
Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:
Silent

I hope this helps sorry if it doesn't :(
Have a good day :)
Stay motivated :)
Answer:
Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.
