Answer: D
Explanation:
Use Darwin’s finches as example they were separated and speciation occurred in the changed beaks
In which situation is speciation MOST likely to occur is few members of the population are isolated from the others.
What can cause speciation?The speciation process usually occurs due to adverse conditions imposed by the environment. Briefly, two causes are attributed for the process to occur: Geographical Isolation: When lineages of a species separate from the rest of the species for environmental reasons.
In this case, a species no longer identifies with it and thus it isolates itself from its environment.

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?
A.silent
B.missense
C.nonsense
D.insertion
Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:
Silent

Janelle thinks that genetic engineering could be used to
make a larger fruit rather than cloning the fruit. Which would best support her point of view? A. Genetic engineering does not cost as much.
B. Genetic engineering does not result in genetically identical organisms. C. Genetically engineered foods never cause allergies in people. D. Genetically engineered foods have not been modified.
Genetic engineering is the process by which scientists choose a particular group of genes and insert them into an organism in such a way that the resulting features will be beneficial to the organism. Therefore, option (B) is correct.
What is genetic engineering?The modification and manipulation of an organism's genes through technology is known as genetic engineering, often referred to as genetic modification or genetic manipulation.
Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating new DNA. Therefore, option (B) is correct.

If energy is released, free energy must be what?
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

Identify the phase of mitosis for each plant cell diagram shown below.
Answer:
1. Metaphase
2. Prophase
3. Telophase
4, 5, 6, 8. Interphase
7. Anaphase
Explanation:
Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.
Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.
Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.
Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.
Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.
In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.
The cellular phases include Interphase (Figs. 4, 5, 6, 8), Prophase (Fig. 2), Metaphase (Fig. 1), Anaphase (Fig. 7) and Telophase (Fig. 3).
The cell cycle can be divided into two major phases: Interphase and mitotic M phase.The Interphase is classified into three subphases: Growth G1 phase, synthesis S phase and Growth G2 phase.The M phase can in turn be divided into Prophase, Metaphase, Anaphase and Telophase.In conclusion, the cellular phases include Interphase (Figs. 4, 5, 6, 8), Prophase (Fig. 2), Metaphase (Fig. 1), Anaphase (Fig. 7) and Telophase (Fig. 3).
