Answer:
Definition of Exergonic Reaction
An exergonic reaction is a reaction that releases free energy. Because this type of reaction releases energy rather than consuming it, it can occur spontaneously, without being forced by outside factors.
In chemistry terms, exergonic reactions are reactions where the change in free energy is negative. Free energy measures the total amount of energy available in a system; negative changes mean that energy has been released, while positive changes mean that energy has been stored.

Answer:
The correct statements are statement 3 and 4.
Explanation:
An alignment of three nucleotides within the RNA or DNA that assists in coding a specific amino acid or instructs the cell to either cease or begin the synthesis of protein is termed as a codon. A sum of 64 probable codons are found that comprise three of the four possible nucleotides, however, only 20 amino acids are present in the majority of the biological species.
The given third statement is true as there are some of the codons known as stop codons that plays an essential role in terminating the process of protein synthesis.
The given fourth statement is also true as codons known as stop codons are not identified by tRNAs, they are identified by ribosomes.
Answer:the steps of a rock cycle are weathering and erosion, transportation, deposition, compaction and cementation, metamorphism, and rock melting so if its not this its that,s the answer
Answer:
If both parents have sickle cell anemia then the individual will be effected with
sickle cell anemia disease.
Explanation:
It is genetic disease which run in a famalies in an autosomal way.If one parent have sickle cell anemia and other dont then the pregnacy will have 25% of risk and if one Parent have a sickle cell anemia and other have sickle cell trait then the pregnancy will have 50% of chances to be effected.A person having sickle cell trait is that who is not effected with sickle cell anemia and dont have the symptoms of disease but in future if the other parent also have same trait then the pregnancy will be effected.Sickle cell anemia triat is having gene S while normal person have Beta gene.
This disease is common in african desents.
Answer:
All the offsprings will be black-furred (Bb)
Explanation:
This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.
According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:
BB - B only
bb - b only
Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:
Bb, Bb, Bb, Bb
All Bb (heterozygous) means that all of the offsprings will be black-furred.
