How is the law of conservation of mass observed in a chemical equation?​

Biology
1 answer:
vodka [1.7K]3 years ago
7 0

Answer:

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

hope this helps :)

1. Green, because it serves as a perfect camouflage against prey in vegetations.

2. It is a process whereby a breeder of animals or plant cultivator, chooses to breed between different species for their characteristics that are inheritable.

3. Mutations is an evolutionary process that helps a specie better adapt to their environment. DNA changes causes by mutation can help lighten or darken colour pigment. Like in the dark-coated mouse, where 9 changes to the DNA coding for color makes its fur lighter for better camouflaging.

Sex-Related inheritance: X chromosome; Non Sex-Related inheritance​
ser-zykov [4K]

<u>What we already know:</u>

All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)

<em>So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex</em>.<em> That means that the gene codes for more than just the sex. </em>

<u>Building on that knowledge: </u>

<em>Sex-Related Inheritance</em> that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas <em>Non-Sex-Related Inheritance</em> is carried on the other thirty chromosomes that the individual also carries.

<em>Sex-Related</em> inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.

Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

<u>Vocabulary:</u>

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
