A student notices that when bananas are kept near other fruits, the other fruits ripen faster. She wonders what causes the other

fruits to ripen more quickly and thinks that bananas must have an influence on the ripening process. She decides to perform an experiment. She gathers bananas and apples and places an apple by itself at location A and an apple next to a banana at location B. She then waits for five days and records the how ripe each apple is.
What would be the next step in this experiment?

Answer:

The options:

What would be the next step in this experiment?

A. construct a hypothesis and record data

B. make observations and draw a conclusion

C. ask questions and construct a hypothesis

D. analyze the results and make a conclusion

The ANSWER should be D

D. analyze the results and make a conclusion

Explanation:

It should be D, the hypothesis has been proposed by her and she's left with conclusion on the experiment. From the type of exleriment, she has little observations to make since there's is a remote conclusion in a set time period.

Answer:

D. analyze the results and make a conclusion

Explanation:

According to the question above, we can see that the student did an experiment based on the steps defended by the scientific method. So, she made an observation, when she realized that when fruits were placed near bananas, they ripened faster. According to this observation, the student created a hypothesis that was "do bananas influence the ripening of other fruits?"

To test this hypothesis, the student set up an experiment, denoting an apple near bananas and another apple away from bananas. After a few days, she recorded the data on what this experiment resulted. Now that she has this data, she can analyze it, getting an answer to her hypothesis and drawing a conclusion about the influence of bananas on fruit ripening.

deff fn [24]
In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.
\frac{230+240}{1000}=0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>

The enzyme telomerase is part protein and part RNA. What would be the most likely effect of a large deletion in the gene that en
Artist 52 [7]

Answer: option A, B and D

Explanation:

The telomeres found at the terminal ends of eukaryotic chromosomes are long repetitive sequences that protects the DNA from being identify as a damage molecule to encourage fusion with other chromosomes. Since replication does not extend down to these 3' ends, the cell recruits the telomerase enzyme which is a ribonucleoprotein that helps to add telomeric repeats using its own RNA component as template to extend this end. Thus if mutation like a large deletion occurs in the gene encoding for this enzyme, the telomerase would not be able to associate correctly with the telomere, the catalytic center also encoding for its RNA polymerase would be altered and the enzymes will not be able to synthesize new telomeric repeats sequences

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend
anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings  will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

Radiation can cause breaks in human chromosomes. However, insects can survive much higher lecels of exposure. Why?
galben [10]

Explanation:

The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and  therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .

As the target of the radiation is the DNA .

Hence , It is clear that insect due to lesser DNA are less prone to Radiations .
