Answer:
B
Explanation:
I got it right :D
An important clue to the structure of DNA was provided by an X-ray diffraction photograph of DNA. Thus, the correct option is B.
What is X-ray diffraction?X-ray diffraction (XRD) is a widely used technique to assess the crystallinity and structure of the solid samples such as biomolecules like DNA and proteins. The crystal X-ray diffraction phenomenon results from the scattering process in which the X-rays are scattered by the electrons of the atoms which are present in the sample without any change in the wavelength.
Rosalind Franklin's X-ray diffraction method patterns of the DNA molecules rendered the important clue from which DNA has the structure of a double helical structure. The most famous X-ray photograph, the Photo 51 is still printed in most of the Biology textbooks.
Therefore, the correct option is B.

B. Identify the species of the beetle and the species of both trees.
C. Determine why the beetle is eating one tree but not the other.
D. Recommend a treatment that will keep the beetles from eating the trees.
ANSWER: B. identify the species of the beetle and the species of both trees (quizlet)
Answers
Answer: It's B,
"Identify the species of the beetle and the species of both trees."
The botanist should firstly study the interaction of these organisms in the ecosystem by identifying the species of the beetle and the species of both the trees. Therefore, the correct option is B.
What are species?A species is a group or organisms that can interbreed and produce viable offspring. The concept of species is used to define a unique type of organism, and it is the basic unit of biological classification.
Species are considered to be different from one another if they are unable to interbreed and produce offspring that can survive and reproduce. This definition of species is known as biological species concept.
In the case given in the question, the botanist should first identify the species of both the beetles and the trees. Then try to deduce a relationship between them which could clarify that the reason of the beetles feeding on those specific trees. Hence, the correct option is B.

What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
Answers
Answer:
The original species will diverge into two new species. It will occur speciation. It will occur some sort of allopatric speciation.
Explanation:
When the original species is divided and placed under different environments, where they can reproduce for many generations, many changes or mutations will occur in each group. These changes will depend on each group´s environment and its ecological pressures and will lead to divergence. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.
The biological concept of species states that individuals of the same species can reproduce because they have a genetic reservoir in common: many genetic variants.
Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.
Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps:
• The emergence of the barrier.
• Interruption in the genetic interchange
• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
Answer:
divergence, potentially giving rise to two different species

If all cells in your body contain the same set of DNA, why is it that some cells become muscles calls, some become skin, or nerve cells?
Answers
Answer:
This is due to CELL DIFFERENTIATION
Explanation:
All living cells are made up of the genetic material called DNA, which are exactly of the same sequence across all cells. However, the cells that contain the same DNA sequence are different in function.
This is as a result of a process called CELL DIFFERENTIATION, which is the process whereby cells specialize or become specific in function as a result of the expresssion or not of certain genes in the DNA sequence of each cell. In other words, cells might contain same DNA sequence but the genes are not all expressed at the same time, leading to the different function. Therefore, some cells become muscle cells, skin, or nerve cells with different functions.

What is the resistance of a circuit with a voltage of 10 volts (V) and a current of 5 amps (A)? Use Ohm’s law to calculate the resistance.
The resistance of a circuit with a voltage of 10 V and current of 5 A is
ohms.
Answers
Answer: R = 2 ohm
Explanation: Based on the Ohm's law
U = R*I ---> R = U / I
R = 10 / 5
R = 2 ohm
Answer:
Answer : The resistance of a circuit is 2 ohm.
Explanation:
Using Ohm's law :
Or,
where,
R = resistance of a circuit = ?
V = voltage of circuit = 10 volts = 10V
I = current flowing in a circuit = 5 A
Now put all the given values in the above formula, we get the resistance of circuit.
Therefore, the resistance of a circuit is 2 ohm.
Which statement describes transform boundaries?
O Rift valleys are formed.
O Mountains are created.
O Faults form in the lithosphere.
Plates move toward each other.
Answers
Transform boundaries are described as faults that emerge in the lithosphere. So, the correct option is C.
What are Transform boundaries?Transform boundaries, which are often referred to as conservative plate boundaries, are places where two tectonic plates move past one another while moving in opposite directions along a fault in the Earth's crust.
Transform borders happen when two tectonic plates move past one another horizontally via a lithosphere fault. As a result of this movement, rocks may break and slide along the fault, resulting in earthquakes. Transform borders do not include the creation or destruction of crustal material, unlike divergent boundaries where rift valleys are formed or convergent boundaries where mountains are built when plates move towards one another.
Therefore, the correct option is C.
