Answer:
The manipulated variable is how many fish you put in the tank. The responding variable is how much the fish have grown.
Explanation:
A manipulative variable is the independent variable in an experiment or equation. It's called “manipulated” because it's the one you can change in the problem. A responding variable is something that “responds” to changes you make in an experiment. Hope this helps!

If a white horse and a black horse are bred together, what percentage of the offspring will be roan and express both colors in their hair?1 point)
100 percent
0 percent
25 percent
50 percent
Answer:
1) 50 percent
2) 50 percent
Explanation:
The dominant traits are those that are expressed phenotypically, whereas recessive traits are masked by the dominant traits.
The percent of offspring having dimples are 50 percent. The percent of offspring will be roan and expressing both the colors will be 100%.The dimples are the traits, which are expressed phenotypically.
Let the alleles for the heterozygous parent with dimples be Dd. The other parent not having dimples will have the genotype dd.
The combination between the Dd and dd will result in:
Dd, Dd - heterozygous combination of alleles
dd, dd - purebred for the alleles
Similarly, the genotype of the hair color of the horse is white and black .
The cross between the parental genotype will result in 100% heterozygous offspring with genotype [tex]\text {C}_w \text{C}_b[/tex]
The result will be due to codominance, in which both the characters of the parent will be expressed in the offspring such that the horse will have black and white colors.
Therefore, the answers will be 50% and 100%.

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%.

Describe surface tension in a group of bonded water molecules that form a ""bead of water""
When water's surface tension is higher than the surface's energy, it beads. Surface tension is a liquid's ability to resist an external force due to the cohesion of its water molecules.
What is surface tension?When water is in a liquid state, the molecules have a tendency to bead up or form droplets because of the mutual attraction that exists between them. Surface tension is a property that is manifested in liquids as a result of this attraction.
The phenomenon known as surface tension takes place whenever the surface of a liquid comes into contact with another fluid (it can be a liquid as well). Most liquids have the tendency to obtain the smallest possible surface area. The top layer of the liquid has the characteristics of a flexible sheet.

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.

Explain how a change in the sequence of nucleotides in a strand of DNA might cause
a protein to malfunction.
Answer:
As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction. If insulin does not work correctly, it may not be able to bind to the insulin receptor. Hope this helps! <3
Explain why the crossbreeding of bison and cattle is both a benefit and hindrance to conservation efforts aimed at protecting bison genetic diversity.
Answer:
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.

What was Mendel's most significant conclusion from his research with pea plants?
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

We have been talking about plant and animal cells over the past couple weeks. Plant cells have two organelles that animal cells do not contain. Name the two organelles that can be found in plant cells but not in animal cells and describe what each of those organelles do. Please answer in at least 5 complete sentences!
Answer:
plant cells have chloroplasts and a cell wall. (they also have one large central vacuole.)
Explanation: Chloroplasts are found only in plant cells. Chloroplasts convert energy from the sun into sugar (glucose). The chloroplast is also where photosythesis happens in the plant cell. The cell wall is also only found in a plant cell. The cell wall protects and mantains the shape of the cell. And you don't have to put this one but the central vacuole is just one big vacuole in a plant cell that stores mainly water and nutrients since plant cells require more water to function, whereas in animal cells they have multiple small vacuoles.
