Answer:
A major transcription factor is inactivated or an oncogene is overexpressed
Explanation:
A microarray is a technique widely used in molecular biology for the detection of the expression of target genes. A microarray is composed of microscopic spots that contain DNA probes which hybridize with the target acid nucleic (generally an mRNA). The hybridization of probe-target produces fluorescence or chemiluminescence, thereby it is possible to detect gene expression in the sample. The inactivation of major transcription factors (e.g., p53) or overexpression of oncogenes (e.g., c-Myc) are well-known to produce aberrant gene expression patterns as observed in this case.
If a purebred white horse C^w and purebred black horse C^B are bred together, what is the likehood that their offspring will roam with both colors represented?
O 0%
O 25%
O 50%
0 100%
Answer:
The likelihood that their offspring will roam with both colors represented is of 100%.
Explanation:
The exposed example brings up the case of a codominance example. When the hair color of horses is codominant, roan coats occur. Roan horses express both the colored and the whited hairs, with some of the animal´s parts expressing mostly the colored hairs, such as head, tail, and legs. These animals have white hair and another solid color (such as black). When two purebred animals with different genotypes and phenotypes are crossed, the whole offspring will be heterozygous. In this case, a purebred white horse C^w and purebred black horse C^B are bred together. The offspring will carry the heterozygous genotype C^wC^B. The offspring will have both red and white hairs.
In codominance, both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both of the alleles (red and white hair). Their phenotype is an additive expression of their parents' genes.

Using the specific steps of the scientific method, tell me how you would use the scientific method to solve this problem: A family wants to test the effectiveness of a misting shower head in conserving (saving) water compared to their regular shower head.
Answer:
Explanation:
Scientific Research is a method used in the construction and testing of a scientific hypothesis.
It has six steps that can be used in solving questions ask or observations made which is A family wants to test the effectiveness of a misting shower head in conserving (saving) water compared to their regular shower head.
Steps to follow:
Make an observation: An observation would be made on how water is been used in the house and how it can be conserved, this observation is what brings about the question asked
Ask a question : The question is
which is more effective in conserving water a misting shower head or regular shower.
Form a hypothesis, or testable explanation: An hypothesis is formulated for the question asked
Example: Null hypothesis: Mistling shower conserves more water than shower head
Alternative: Mistling shower conserves less water that normal shower.
Make a prediction based on the hypothesis: Predictions are made on what could be the cause if there is indeed a difference and what could cause the difference
Test the prediction: An experiment is conducted to test the hypothesis if indeed Mistling is better than normal shower, the appropriate method is determined to be used for the experiment.
Iterate: The result gotten helps to butters our hypothesis if its to be acceoted or rejected. If rejected further research can be conducted on the effectiveness of normal shower in conserving water.
when two true breeding pea plants that show contrasting traits are crossed 1) mention the pod shape in F1 generation 2)work out the cross upto F2 generation 3) compute the relative fraction of various genotypes in the F2 generation
Answer:
1.) Inflated pod shapes (Cc) in the F1 generation
2) See attached image for the work out of the cross from P generation to F2 generation.
3). CC- 1/4, Cc- 1/2, cc- 1/4
Explanation:
This question is related to the pod shape trait encoded by a single gene in pea plants. The alleles for inflated pod shape (C) is dominant over the allele for constricted pod shape (c). This means that allele "C" will be expressed over allele "c" in a heterozygous state.
The two truebreeding parent plants will have genotypes: CC (inflated pod shape) and cc (constricted pod shape). When these two plants are crossed, an all heterozygous plant with genotype: Cc will be formed in the F1 generation. Since, C is dominant over c, the F1 Cc plants will have an inflated pod shape phenotype.
The F1 Cc plants are self-crossed to produce the F2 generation offsprings i.e. Cc × Cc. The gametes C and c will be produced by each F1 parent, which will be used to draw a punnet square (see attached image). From the cross, offsprings with genotypes: CC, Cc and cc are produced in the F2 generation.
CC (phenotypically inflated pod shape)- 1/4
Cc (phenotypically inflated pod shape)- 1/2 or 2/4
cc (phenotypically constricted pod shape)- 1/4

Answer:
Organelles
Explanation:
Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.
Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.
The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.

Create a scientific question that could be answered with the help of a microscope
Answer:
"Find the difference on the basis of the shape of animal and plant cell?" is a scientific question that can be answer with the help of microscope.
Explanation:
Microscope is an instrument that helps in study the very small structures by magnifying its size with the help of different magnifying lenses of different magnifying power.
Microscope bends the light towards the eyes through the lenses which make them look larger than the actual size of the object. Microscope can help an individual to see minute details that eyes can not see normally.
Shape of the cell of various organism like plant and animals can be study with the help of microscope and can be find the differences.
Thus, "Find the difference on the basis of the shape of animal and plant cell?" is a scientific question that can be answer with the help of microscope.

A suggested and testable explanation for an event is called a hypothesis. Therefore, option (A) is correct.
What is a hypothesis?A hypothesis is a proposed explanation for a phenomenon that can be tested through scientific investigation. It is an educated guess or tentative answer to a scientific question based on prior knowledge and research. A hypothesis should be specific, testable, and falsifiable, meaning that it can be proven wrong through experimentation.
Hypotheses are often used in scientific experiments to guide the research and determine the outcome. A hypothesis can be based on observations, theories, or previous research, and it should be clearly stated in a way that allows it to be tested and either supported or rejected by the evidence. The process of testing a hypothesis involves designing and conducting experiments, collecting and analyzing data, and drawing conclusions based on the results. The ultimate goal of a hypothesis is to gain a deeper understanding of the natural world through the scientific method.
