Answer:
The correct answer is - option D. A person rubs a shoe on a rug, causing extra electrons to be transferred to the shoe.
Explanation:
Current electricity is a flow of charged particles that moves through space or any type of electrical conductor. Usually, the transfer of the electric current takes place through a wire. There are many examples of current electricity such as lightning and static electric charge.
Electric static charge is generated due to the imbalance of particles present on the surface or within the material, normally friction leads to this imbalance in particles of the material such as when a person rubs his shes on rug created an imbalance in the electrons and then transfer to the shoe.
Answer: electrons flow from an outlet into a toaster, causing it to heat up a slice of bread
Explanation:
A researcher observes that when two heterozygous plants with red flowers are crossed the resulting offspring include plants with red white, or pink flowers The researcher proposes the rullrypethesis that flower color is the result of independent assortment and incomplete dominance The researchers climesach square value of 7.3 Assuming two degrees of freedom which of the following is the correct Interpretation of the chi-square analysis, using apvalue of 0.05 ? A. The null hypothesis should be rejected because the critical value is less than the calculated value B. The null hypothesis should not be rejected because the critical value is less than the calculated value C. The null hypothesis should not be rejected because the critical value is greater than the calculated value D. The null hypothesis should be rejected because the critical value is greater than the calculated value
Answer:
the correct answer is A
Explanation:
Chi squared is a statistical test that is used either to test whether there is a significant difference, goodness of fit or an association between observed and expected values. the sqaure for this is less than the statistical value originally found, therefor making the null hypothesis void.
The Chi-square test is defined as the statistically significant difference between the expected frequency and observed frequencies.
The correct option is:
Option A. The null hypothesis should be rejected because the critical value is less than the calculated value
The Chi-square test is based on hypothetical facts to determine the significant difference in the calculated and observed frequencies.
The null hypothesis is rejected because the square for the value is less than the statistical or calculated value originally found. Thus, the hypothesis is null and void.
Therefore, the correct option is A.

Which of the following describes a way that decomposers are important to an ecosystem?
Answer:
Decomposers recycle essential nutrients back into an ecosystem.
Explanation:The decomposers are the small microorganisms which can be found in the soil habitat. These organisms obtain energy by break down of organic matter generated after the death of plants, animals and their residual matter. Through the process of decomposition the decomposers release nutrients such as nitrogen and carbon back to the environment. These nutrients are absorbed by the plants through soil. This way the nutrients are recycled in an ecosystem by decomposers.

Process used when it is time for an
entire organism to reproduce
Answer: reproduction
Explanation: the process by which an organism produces its offspring is called reproduction.
The process used when it is time for an entire organism to reproduce is called MEIOSIS.
Meiosis is a type of reductional cell division by which a parental cell divides to produce four daughter cells having half of the genetic material (DNA) compared to the parent cell.Meiosis is used by organisms with a sexual mode of reproduction to produce new organisms by a process called fertilization, which involves the fusion of two meiotic cells, one from each parent.Germinal (sex) cells reproduce by meiosis, while somatic (body) cells reproduce by mitosis.In conclusion, the process used when it is time for an entire organism to reproduce is called MEIOSIS.

In two to three sentences, describe why Prunnett squats do not accurately demonstrate how asexual reproduction passes on traits.
Answer:
Punnett Squares are unable to predict the offspring of an asexual organism because there is only one parent from which the offspring can receive genes from. The whole point of a Punnett Square is the fact that it covers all possible offspring outcomes besides mutations from the usual two parents.

Teresa did a trick in which she placed dishes on a tablecloth placed on a card table. She pulled quickly on the tablecloth, and it came off the table, leaving the dishes behind on the table. Teresa’s friend tried the same trick and ended up with a pile of broken dishes on the floor. Teresa told her that she didn’t pull the cloth fast enough. She also said that her friend might have better results with heavier dishes. Using Newton’s laws, explain why these were good suggestions.
Answer:
the speed of the cloth being pulled left no time for the dishes to move. heavier dishes have a harder time moving because of the gravitational pull. In the second law, the force on an object is equal to its mass times its acceleration. if the dishes had no acceleration they will not move.
Explanation:
The plates couldn't move because of how quickly the cloth was being dragged. According to the second law, an object's force is determined by multiplying its mass by its acceleration. The dishes won't move if there was no acceleration.
What is newton's second law of motion?When there are unbalanced forces acting on an object, Newton's second law of motion applies. According to the second law, the mass of the item and the net force acting on it both affect how quickly an object accelerates.
An object's acceleration is directly proportional to the net force applied on it and inversely proportional to its mass. An object's acceleration increases as the amount of force exerted on it does.
A decreasing acceleration is caused by a rise in an object's mass.
Therefore, The plates couldn't move because of how quickly the cloth was being dragged. According to the second law, an object's force is determined by multiplying its mass by its acceleration. The dishes won't move if there was no acceleration.

The investigations conducted by Edwin Chargaff support the idea that DNA is the source of heritable information, and they also show a relationship between the ratios of the different nitrogenous bases in DNA. Based on the results of Chargaff's research, which is the best estimate of an organism's DNA base composition that contains 28.0% thymine
all the thymine pairs with adenine, therefore there is the same number of adenine and thymine bases and the same percentage
so we have 28%thymine and 28% adenine
100-28-28=44% left
this 44% is guanine and cytosine. All of the guanine pairs with cytosine and all of the cytosine pairs with guanine so we have 44/2=22% cytosine and guanine
composition:
28%adenine
28%thymine
22%guanine
22%cytosine

Explanation:
In humans, freckles (F), widow’s peak (W) and attached earlobes (E) are all unlinked dominant traits. A man with freckles, widow's peak and attached earlobes marries a woman with freckles, straight hairline, and attached earlobes. Their first child has no-freckles, straight hairline, and detached earlobes. What is the probability that their second child has no-freckles, straight hairline, and attached earlobes? Select one:
Answer:
The correct answer is - 3/32.
Explanation:
We know that freckles F is dominant over no freckles f, similarly, Widow's peak W is dominant over straight hairline w and attached earlobes are dominant over free earlobes.
So, the combination of alleles for each phenotype would be:
No freckles = ff , Freckles = FF, Ff
Free earlobes = ee , Attached earlobes = EE, Ee
Straight hairline = ww , Widow's peak = WW, Ww
In the question, it is given that the first child has no-freckles, straight hairline, and detached earlobes that would be - ffwwee genotype and as it is given that all alleles are in recessive which means both parents must have recessive alleles.
So, the correct genotype of the man will be FfWwEe and the woman will be FfwwEe.
(man = freckles, widow's peak, and attached earlobes (F_W_E_) and woman = freckles, straight hairline, and attached earlobes (F_w_E_))
then cross between: FfWwEe × FfwwEe
The probability of the freckles and no freckles would be-
Ff × Ff = 3/4 freckles, 1/4 no freckles
The probability of the widows and straight hairline would be-
Ww × ww = 1/2 widows peak, 1/2 straight hairline
The probability of the free earlobes and attached earlobes would be-
Ee × Ee = 3/4 attached, 1/4 free earlobes
Combined possibility of all three phenotypes: no freckles, straight, attached would be = 1/4 × 1/2 × 3/4 = 3/32
Thus, the correct answer is - 3/32.

changing how animals are handled at slaughter
Answer:
The answer is "supplementing the animals’ feed"
Explanation:
Animal welfare implies how a creature is adapting to the conditions in which it lives. An animal is in a decent condition of welfare on the off chance that it is solid, agreeable, very much fed, protected, ready to communicate intrinsic conduct, and on the off chance that it isn't experiencing disagreeable states, for example, torment, dread, and pain. Great animal welfare requires infection avoidance and veterinary treatment, proper asylum, the board and sustenance, sympathetic taking care of and empathetic butcher or murdering
