Answer:
This question lacks options, however, it can be answered based on general understanding of the topic
The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
Answer:
The correct answers will be option-B
Explanation:
The polymerase chain reaction is the technique which involves the chain of reaction. The reactions are performed which polymerises or make exact copies of the DNA in higher number from a small sample in vitro-conditions.
The PCR technique is based on the DNA replication mechanism which involves the DNA primers and Taq polymerase, a type of DNA polymerase enzyme.
The PCR proceeds in three steps that are denaturation, annealing, and extension in which the DNA is denatured to break the hydrogen bonds, the addition of the primers at both ends called reverse and forward primers which function simultaneously, synthesis of DNA and extension in which the sample is cooled.
Since the primers are added to both the strands and not on the same strands therefore, the selected option is the correct answer.
Answer:
Why do the population of prey and predators fluctuate differently meaning their respective population rise and fall at different points.
In biology, fluctuation of prey and predators could be attributed to so many factors which are listed below;
Migration of either the prey or predator would allow fluctuation to occur, when prey which is meant to be fed on reduces in number then this leads to competition among predators, hence; overcrowding and then leads to feeding on each other as result of scarcity of prey.
overpopulation of predator could also fluctuate the population of both in such a way one regulate another. When predators are overpopulated, the feeding pattern would be voracious on the prey which might lead to drought or scarcity of prey , hence; causes fluctuation in prey population
Explanation:
Answer:
blood with certain proteins clump together when exposed to certain antibodies. A patient has type AB blood. If they received a transfusion of type B blood, predict and explain what would happen. Agglutination would occur because a person with type B blood cannot receive AB blood because they have A antibodies.

Answer:
baseball field and playground remain on the place and pond will not to be built.
Explanation:
Baseball field and playground are recreational places in the cities which increases the physical activities and health of the children and adults living nearby. If these places are removed from cities, it has many negative effects on the people of the society especially on children. If a pond will be built in place of these baseball field and playground, there is no better effect on the people only increase the beautification of the area. So health of the children is more important than beautification of the area.
