Answer:
The options to this question are:
A) allele
B) codon
C) nucleotide
D) chromosome
The answer is A) allele
Explanation:
RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.
However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

First one is a and second one is b
Answer; All the above
A) an atom seeks to fill its outer shell of electrons
B) an atom seeks to balance its positive and negative charges
C) the reaction will result in paired electrons
Explanation;
-In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
-During a chemical reaction an atom may lose of gain electrons resulting positive and negative ions (ionic bond formation) or may result to the paired electrons (sharing of electrons).
Answer:
The inducer will combines with the repressor and inactivates the pathway.
Explanation:
Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.
In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.
Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
