I would say B: A bar graph.
definitely not c or d
Answer:
B) The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.
We know this by virtue of the law of conservation of mass.
The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".
Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.
The second choice is the right one.
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
Answer:
The forensic autopsy is preformed by "Forensic pathologist".
Explanation:
The forensic pathologist would perform a forensic autopsy, Forensic pathologist will focus on the cause behind the death by studying the body or the corpse. Most probably they do the postmortem examination. The forensic pathologist is also a medical doctor, who must have completed the training in anatomical pathology with specialization in forensic pathology. The forensic pathologist are basically there to find the cause and also the manner of death. They are trained for performing autopsy, helps in evaluation of historical and law enforcement investigative information, documentation in sexual assault, helps in collection of the medical evidence.
Sex differences are biological and gender differences are culturally prescribed. Sex differences refers to the difference in behavior and mental functions between male and female as a result of biological difference while gender differences refers to the differences that occur between male and female as a result of cultural factors.
