Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.

Answer:

Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Explanation:
Peptide bonds are- Any reaction that combines two monomers in a reaction that generates H2O as one of the products is known as a dehydration reaction, so peptide bond formation is an example of a dehydration reaction.
Answer:
water is a molecule which will be made
in the figure, which number represents dna synthesis?
The number that represents DNA synthesis in the figure would be II.
DNA synthesis happens at the S phase in the interphase of the cell cycle, just after the G1 or cell growth phase and before the G2 or protein synthesis phase.
During the S phase, the amount of DNA in the cell doubles as replication of DNA takes place. However, the number of chromosomes remains constant.
The doubling of the amount of DNA is responsible for the sharp rise in the line that represents the amount of DNA in the figure. Thus, the region of a steep rise in the amount of DNA would represent the DNA synthesis phase.

Observe the model below. Explain one strength(advantage) of the model and one limitation ( disadvantage) of the model
answer ASAP
As to the model of the different types of saccharides displayed, we can name its efficiency as a clear strength, and its lack of more examples as a limitation.
Using models to display information can be advantageous in that they allow the user to visualize something that may otherwise be difficult to picture. This increases memory retention and increases learning.
One example of a strength displayed by this model is its efficiency. By this, I mean that the model provides a clear and easy way to compare the differences in structure between the types of saccharides by positioning them all onto the same page, near one another enough to make quick and easy comparisons.
The noticeable limitation of the model, however, is its lack of further examples. The model in question shows a single example for each type of saccharide, limiting the user's knowledge to the difference between the types only. After using this model, the user will still lack information as to how saccharides of the same type can vary from one another.

why does cell division occur in sexually reproducing organisms?
Answer:
to produce a complex multicellular individual
Explanation:
hope this helps
Cell division occurs in sexually reproducing organisms to maintain the organisms growth and development. Cells have a particular life cycle after which they die. These cells need to be replaced constantly.
What is Cell division?Cell division is the fundamental process to all living organisms and required for the growth and development of organisms. It is an essential means of reproduction for all the living things, cell division allows organisms to maintain their number and to transfer their genetic material to their offspring.
The role of this process in sexual reproduction is to produce sex cells (gametes) and to repair the genetic defects in germ line cells (sex cells). Both sexual and asexual organisms go through the process of mitosis. However, sexual reproduction also includes meiosis which maintains the number of chromosomes in off-springs.
