Answer: to predict the probability of offspring genotypes
Explanation: Punnett squares are developed to predict the probability of offspring genotype. Punnett square is a square shaped diagram used for predicting the possible genotypes of a cross between two organisms. Punnett square is named after Reginald C. Punnett, who invented the approach. In punnett squares, the genotypes of the parents are written on the top and left hand side of the square while the possible genotypes of their offsprings are written in the boxes.
Answer:
Explanation:
The objective is to conclude if the statements are true or false based on facts.
1)
True
2) 
False
This is because their ancestor is a Chordate who doesn't have a vertebral column but a notochord.
3) True
4) 
False
This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).
5) 
False
The taxa of turtles share a more common ancestor with frogs compared to bass.
6) 
False
The common distant ancestor for leopards and lancelets is known as Chordates
Answer:
introduces a premature stop codon into the mRNA
Explanation:
A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.
There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.
The reason that might cause a reaction that originally proceeds through the path of X to change and proceed through the path Y is the addition of a catalyst.
<h3>What is a catalyst?</h3>
A catalyst is a substance that provides an alternative path for reaction. This implies that the energy tat s required to surmount the energy hump as the reactants are converted into products have been reduced. This can be seen in the fact that the energy hump between the reactants and the products in Y is lower than that in X
Thus, we could say that the reason that might cause a reaction that originally proceeds through the path of X to change and proceed through the path Y is the addition of a catalyst. The catalyst lowers the activation energy of the reaction.

Answer:
The correct answer is - Grant's research on finches on the Galapagos islands.
Explanation:
Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.
It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability. Due to this natural selection and adaption the number of larger beaks in finches is increased over the real time.
