Answer:
Discover the volume of a balloon.
Explanation:
Get a balloon and a piece of paper. Cut the paper to make a line, and make sure it is 100 cm x 2 cm Take on of the balloons and inflate it several times so you are sure you can inflate the balloon with only one breath. Take a deep breath and inflate the balloon. Use a binder clip to hold the neck so no air escapes. Make a measurement of the circumference of the balloon using v = c3/6(pie)2 - the formula is c cubed divided by 6 times pie squared equals volume. Create a graph for them to answer, and then give questions for them to turn in.

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
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.
Suppose a gene from a cow is introduced into a frog. This results in a ________ transgene.
Answer:
Heterologous transgene.
Explanation:
Heterologous transgene can be defined as the expression of a gene from another animal into another. Such an animal that this gene is introduced to does not have such a gene in them naturally, this is done through a firm of DNA technology.
So when a gene from an animal such as a cow is put into another animal like the frog, the result is heterologous transgene.

"If a scientist isolates genes for Hepatitus B antigens from a Hepatitus virus, then inserts them into a bacterial plasmid and replicates the bacteria in a fermenter, what product will be collected?"
Answer:
You could get a bacteriophage as a product.
Explanation:
Bacteriophages are viruses housed within bacteria, which take over the bacterial replication mechanism to multiply and replicate in a dependent manner.
The combination of the hepatitis b virus with a bacterium would end up forming a much more potent bacteriophage with higher virulence factors than the virus or the bacterium itself.

____________________ are structures inside cells that perform specific functions and are often enclosed in membranes; these can be seen with an electron microscope. Your answer:
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.

Answer:
1.hypothesis.
hope it helps!
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.

It is constant throughout Earth's atmosphere.
D.
It is measured using a thermometer.
Answer:
B. It decreases as you move away from Earth's surface.
Explanation:
The atmospheric pressure is maximum at the surface of the Earth and it decreases with the increase in the elevation. In the mountains regains and on the cliff of the mountains, the atmospheric pressure is less as compared to the ground level. This happens because the density of the cool air is greater than the warm air. The decrease in pressure causes mountain sickness and many other problems to people when the elevation increases.

When the enzyme is used in the reaction it is bound to the substrate and releases product and the enzyme is unchanged, hence option b is correct.
What is the enzymatic reaction?An enzyme can be employed for other reactions after it has catalyzed a reaction and been freed from its binding to a substrate.
There is no change at all in the enzyme that has now been liberated and is prepared to catalyze the transformation of another molecule of the substrate into a product.
As a catalyst, it is crucial to keep in mind that the enzyme is not permanently changed by the reaction instead when the reaction is over, the enzyme returns to the condition it was in before the reaction started.
Therefore after a reaction enzyme can reuse for another reaction, hence option b is correct.

A student hypothesized that EC growth might be affected by the DNA from circulating erythrocytes. Is this student’s hypothesis reasonable?
Answer: The options are not given, here are the options.
A) No the DNA in circulating erythrocytes ins needed to help transport O2 through the capillaries
B) No circulating erythrocytes contain DNA.
C) Yes DNA is responsible for cell division in most cells
D) Yes circulating erythrocytes carry DNA nutrients through the capillaries
The correct option is B.
No circulating erythrocytes contain DNA.
Explanation:
Erythrocytes or red blood cells is a biconcave disc that contain haemoglobin which help to carry oxygenated blood in the body.
Circulating erythrocytes do not contain dna because they lack nuclei and organelles, cannot synthesize any RNA, therefore cannot divide and have limited repair capabilities.
Because they cannot carryout protein synthesis, no virus can evolve and invade the red blood cells.
Which of the following options is correct?
It was important that Mendel examined not just the F1 generation in his breeding experiments, but the F2 generation as well, because
a) he obtained very few F1 progeny, making statistical analysis difficult.
b) parental traits that were not observed in the F1 reappeared in the F2.
c) analysis of the F1 progeny would have allowed him to discover the law of segregation, but not the law of independent assortment.
d) the dominant phenotypes were visible in the F2 generation, but not in the F1
Answer:
b
Explanation:
It was important that Mendel did not limit his study to just the F1 generation because parental traits that were not observed in the F1 reappeared in the F2.
For example, in across involving a true-breeding yellow seedcoat pea plant and a true-breeding green seedcoat pea plant, all the F1 offspring would be yellow provided that the yellow seedcoat is dominant over the green seedcoat. The green seedcoat trait will only reappear in F2 offspring.
If the breeding experiment is limited to just the F1 generation, of course, the parental green seedcoat trait will not surface at all.
The correct option is b.
