how are dna fragments separated on an agarose gel during electrophoresis?
Answer: the smaller particles will move further down the gel
Explanation:
DNA is negatively charged because of the negative charges on the phosphate backbone. What you do in an electrophoresis is basically put DNA particles in something similar to Jello, and then put a positive charge at the far end of the gel.
All of the negatively charged DNA is attracted to the positive far end. However, the smaller pieces of DNA will be less tangled in the gel, and can reach the end much quicker.
This allows you to determine the large vs smaller particles basically
Q6.7. If a person is heterozygous for the triangle32 allele of the CCR5 gene, how many of the four daughter cells produced by have the3
Given the characteristics of hereditary genetics, if a person is heterozygous for a given allele, of the four daughter cells produced, the amount that would have the gene is dependent on the spouse's genetic makeup but ranges from 50-100%.
When we say that an individual is heterozygous for a given trait, we mean that of the two alleles that this individual possesses for the given trait, one is of the desired type and one is not. Whereas an individual who is hom-ozygous for a given trait will have both alleles of the same kind.
For example, if we were to look at the allele for blue-colored eyes, a heterozygous individual will have one allele which corresponds to blue coloration, and one allele that corresponds to another color, and a hom-ozoygous will have both alleles for blue eyes. In order to accurately predict the expression of the gene in the offspring of an individual, we use a punnet square (see attached image).
Assuming that the allele in question is dominant in nature, this allows us to see that of the four daughter cells of an individual that is heterozygous for the given allele, the number that will have the triangle32 allele are:
50% (2) if crossed with a spouse who does not have the allele75% (3) if crossed with a spouse who is also heterozygous for the allele100% (4) if crossed with a spouse who is hom-ozygous for the alleleIn conclusion, we can say that the outcome of the cross is entirely dependent on the genetic makeup of the spouse, as well as the dominant or recessive nature of the allele in question, but can accurately predict an outcome in the range of 50-100%.

Mendel's most significant conclusion from his research with pea plants is that Traits are inherited in discrete units and are not the results of blending.ʺ The correct option is B)
What was Mendel's law?Mendel Gregor was s scientist and a botanist. He gave three laws of inheritance. The three laws are of very importance to the field of genetics.
The law of inheritance and the law of segregation say that the traits in the other generation are always passed down segregated, not blended. The traits are just dominant and recessive in the generations.
Thus, the correct option is B) Traits are inherited in discrete units and are not the results of blending.ʺ

Answer:
0 = -2, hence no solution.
Explanation:
4x + 2(x-5) = 3(2x-4)
4x + 2x - 10 = 6x - 12
6x - 6x = -12 + 10
0 = -2

Charles Darwin thought that evolutionary change was gradual, continuous change over long periods of time. This rate of evolutionary change is referred to as:
A. Punctuated equilibrium
B. Gradualist if equilibrium
C. Phyletic gradualism
D. Phyletic punctuation
Answer:
A. Punctuated equilibrium
Explanation:
Charles Darwin understood that evolution was a slow and gradual process. By gradual, Darwin did not mean "perfectly smooth," but rather, "stepwise," with a species evolving and accumulating small variations over long periods of time until a new species was born.

how is the energy that earth absorbs different from the energy that earth emits
Answer: thats geology not biology
Explanation:
Energy that earth absorbs different from the energy that earth emits is called geology.
What is Geology?The word geology means 'Study of the Earth'.
It is also known as geoscience or earth science, Geology is the primary Earth science and looks at how the earth formed, its structure and composition, and the types of processes acting on it.
Geology is concerned with the history of the earth over the course of its 4.5 billion year life. By studying the structures of the earth we can unlock its hidden past and anticipate its future.
All levels of schooling include geology. The study of geology fosters analytical abilities, a global perspective on the globe and its interconnected systems, and a grasp of numbers and maps.
Therefore, Energy that earth absorbs different from the energy that earth emits is called geology.

While the bison gene pool is currently much healthier than that of the cheetah, only one herd among the 4% of all protected bison herds has no known cattle ancestry. Cattle ancestry has helped boost the total population of bison and has increased such herds’ genetic diversity, but those herds do not help protect the bison’s original gene pool.
