Answer:
91.07%
Explanation:
Given the expression
102/112 x 100
This can also be expressed as;
= (2*51)/(2*56) * 100
= 51/56 * 100
= 5100/56
= 91.07%
Hence the percentage of viable cells is 91.07%

A tall pea plant results from a dominant tall allele while the short phenotype results from two recessive alleles. What is the frequency of short offspring (pp) when a tall pea plant with one tall allele (Pp) is cross-pollinated with a short pea plant (pp)?
Answer:
0.5
Explanation:
Took the test xd ♡
The probability of short pea plant when a heterozygous parent cross with recessive is 0.5.
Law of dominance:
The cross between two pure parents results in the heterozygous dominant offspring in the first generation.
Here,
Parents are
P- dominant tall
p - recessive
Pp x pp
The cross,
p p
P Pp Pp
p pp pp
From the cross it is clear that 50% of the offspring will have recessive alleles.
Therefore, the probability of short pea plant when a heterozygous parent cross with recessive is 0.5.

Why do specialized plant cells lose their ability to divide
Answer:
The cells of permanent tissues do not divide. Cells derived from divisition of meristematic to see take up specific role and lose the ability to divide

Which influence has immigration and migration had on the population of Texas?
A.) It has kept the growth rate of Texas the same as the growth rate of the United
States.
B.) It lowered the amount of cultural and economic activity in Texas.
C.) It contributed to the 38% of Hispanic Texans as of 2010.
D.) It decreases the need for public services in rural communities.
Answer:
The answer is choice C.
Explanation:
In this question, I will use the following format: two d*mbs, a trick, & a true. In this strategy, there are two d*mb answers, one answer made to trick the reader, and one true answer (which is the correct answer).
The two d*mbs of this problem are choices B and D. B simply makes no sense since immigration and migration would increase the amount of cultural and economic activity in Texas if anything. I feel as though D is illogical because it is more likely that immigration and migration would increase the need for public services in rural communities. Due to B and D being the opposite of what is necessary for the answers to be true, they can both be swiftly eliminated.
A is the trick of this question. Although it may seem valid at first, there is a fatal flaw about it: the fact that Texas is within the United States. Texas, despite its size and population, is one singular part of the US. It is impossible for Texas to be the only part of the United States to grow. As a result, the growth rate of Texas can never be the same as the growth rate of the United States.
C is the true in this problem. Immigration and migration contributing to the 38% of Hispanic Texans (as of 2010) is indeed a logical answer that adds up. Additionally, when looking at the official resources that this question is derived from, the text clearly states that 'The numbers and percentages of Hispanics in Texas grew greatly between 2000 and 2010. About 2.8 million more Texans identified themselves as Hispanic in 2010 compared to 2000. Hispanics represented 38 percent of all Texans compared to about 32 percent in 2000.' While this information may not seem all that important at a first glance, it actually supports this answer quite a bit. The text clearly provides valid proof of answer choice C; it gives the cause of answer choice C quite plainly and undeniably.
This means that A is the trick, B and D are the d*mbs, and C is the true. Due to the evidence and verification previously stated in my answers, it is quite clear (to me) that the answer is indeed choice C.

Which of the following is an example of genomic imprinting in humans? Which of the following is an example of genomic imprinting in humans? A random pattern of autosomal allele inactivation is observed. In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed. The maternal and paternal alleles of a gene pair are both expressed. Human males have only one Y-chromosome and one X-chromosome. One of the two X-chromosomes in females is randomly expressed and the other is repressed.
Answer:
In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed.
Explanation:
Genomic imprinting is an epigenetic phenomenon where alleles are differentially expressed depending on their parental origin (for example, paternally expressed when it is inherited from the father). Genomic imprinting is controlled by epigenetic modifications (for example, DNA methylation, histone acetylation, etc) which works together to preferentially activate the expression of the allele inherited from one parent and simultaneously silence or “imprint” the expression of the allele inherited from the other parent. In humans, an example of genomic imprinting is the case of the insulin-like growth factor 2 (Igf2) gene, which is maternally imprinted (repressed), thereby this gene is only expressed from the paternal allele.
Complete the statement about genetic variation.
Meiosis contributes to genetic variability when
the chromosomes line up randomly during
metaphase 1 anaphase I prophase I. This
random line-up means that when the cell divides,
the number of chromosomes in each cell is the
same, but the contents are not. This process is
called | independent assortment |gene linkage |
crossing over|. During meiosis, |gene linkage|
|independent assortment | crossing over | increases
genetic variation because it shuffles portions of
chromosomes around.
Answer:
1. Metaphase 1
2. Independent assortment
3. Crossing over
Explanation:
Meiosis is a kind of cell division that reduces the chromosome number of the parent cell by half. It only occurs during sexual reproduction and ensures genetic variation in sexually reproducing organisms.
Meiosis contributes to genetic variability when the chromosomes line up randomly at the cell plate during METAPHASE 1 of meiosis. This process of random alignment is called INDEPENDENT ASSORTMENT of genes. Generally, meiosis is able to ensure genetic variability due to a process called CROSSING OVER. Crossing over is a process whereby nonsister chromatids of homologous chromosomes exchanges/shuffles genetic contents.

Look at the apparatus shown. It can be used to compare the amount of __________ given out by different fuels. What one word completes this sentence?
It can be used to compare the amount of energy given out by different fuels.
Thermometer is that apparatus which is used to measure the temperature of the liquid or solution. Temperature is a measure of the kinetic energy of the molecules that is present in a substance. When we record the temperature of something, we are collect information about how fast the molecules are moving in the liquid by heating the solution.
In this experiment, thermometer is dipped into the solution in order to record the amount of energy given out by burning of different fuels so we can conclude that the apparatus is used to measure the amount of energy given out by burning of different fuels.

A plasmid contains a multiple cloning site inside the coding region of the lacZgene and also contains an ampicillin resistance gene at a separate locus. When cells are transformed with a successfully recombinant plasmid containing a piece of DNA cloned into the multiple cloning site, what color will the colonies be when grown on an agar plate containing ampicillin and X-gal
Answer:
The correct option is white.
Explanation:
As the options are not given, the options are found online and are as follows;
(a.) green (b.) white (c.) colonies will not grow (d.) blue (e.) clear
Out of this, white is the true option because in recombinant plasmid lac Z gene is disturbed and cannot produce beta galactosidase enzyme and there is no hydrolysis of x gal and no blue so recombinant plasmid gives white colonies)

Answer:
C. average distance between variable scores and the mean in a set of data
Explanation:
The standard deviation is used to find how far data points are from the mean. This can be used to create a bell curve, which represents what percentile data points are relative to the set. A bell curve shows how the data points are distributed. Standard deviation can be found from an entire data set or just a sample.
