Zoologist: Horseflies are attracted to horizontally polarized light, which reflects off large, dark animals that they bite. This may explain why zebras evolved vertical stripes—the stripes cancel the horizontal polarization of light and thus make zebras less attractive to horseflies.
In order to assess the plausibility of the zoologist's hypothesis, it would be most helpful to know whether
A. any insects other than horseflies are attracted to horizontally polarized light.
B. the vertical stripes on zebras make it easier for any insects other than horseflies to see them.
C. animals that horseflies commonly bite have evolved other means of reducing the impact an frequency of those bites.
D. any biting insects other than horseflies are strongly attracted to zebras.
E. zebras' vertical stripes provide camouflage protection against certain large predators potentially very dangerous to zebras.
Answer:
D. any biting insects other than horseflies are strongly attracted to zebras.
Explanation:
In order to assess the plausibility of the zoologist's hypothesis, it would be most helpful to know whether if any other insects other than the horseflies are strongly attracted to the Zebra. If other insects are attracted to the zebra, we can then try to research and see if these other insects also show tendencies to be attracted to horizontally polarized light before we can conclude on this hypothesis. The hypotheses will hold more strongly if the same phenomenon applies to other biting insects attracted to the Zebra.
What is the controversy behind banning oxo-biodegradables?
Answer:
Oxo-biodegradables do not meet international biodegradation requirements, which has caused the authorities to prohibit their use, contrary to their formulators who defend their benefits in the environment.
Explanation:
Oxo-biodegradables are a type of plastic that can be broken up into tiny pieces, but that is not biodegraded by the action of nature. In this case, this type of plastic does not meet international biodegradation requirements, in addition, it can cause pollution, as its mini particles can affect rivers, soils, crops, in addition to being dispersed in the air and being eaten by animals.
The great controversy is that the creators of this type of plastic defend their benefit in the environment, however the authorities, considering the polluting potential of oxo-biodegradables, prohibited its use.
A version of a gene is called a(n)
O allele.
O autosome.
O karyotype
O phenotype.
Answer:
allele
Explanation:
An allele can be defined as a variant of a gene localized at the same locus or chromosome position. These gene variants may encode the same protein (when different alleles encode the same protein sequence) or different protein variants (when nucleotidic differences encode distinct protein sequences). It is important to note that the diploid organisms (like humans) have two alleles for each gene, which are localized on homologous chromosomes.
A version of a gene is called an allele. Genes are sections of DNA that hold the instructions needed to make certain proteins or useful RNA molecules. Hence the correct option is A.
Alleles are distinct versions or variants of a gene that can cause changes in the trait or feature the gene controls.
Alleles are found at specific locations on chromosomes known as loci. Each gene is present in two copies in humans, one from each parent.
As a result, a person might be heterozygous (having two copies of the same allele for a given gene) or homozygous (having two copies of two distinct alleles).

Cigarette smoke contains a chemical that specifically mutates p53 and inactivates it. As a result of this mutation, what would happen in the affected cells? A.DNA damage would accumulate B. Cell death would not be activated C.The cell cycle would continue in spite of DNA damage D.All of the above
Answer:
The correct answer is - option D. all of the above.
Explanation:
Smoking cigarettes or consumption of tobacco contains chemical that is responsible for the mutating p53 gene specifically which inactivates the action of p53.
TP53 mutation changes the amino acid in the p53 protein which produces the altered or modified version of protein that is incapable of performing its action of repairing damaged DNA during cell cycle for genome stability. DNA damage would be accumulate as it is not able to control the cell division by apoptosis and cell death would not be activated.
Thus, the correct answer is - option D.

Which of the following processes is likely to occur in the leaves of a plant exposed to an atmospheric oxygen level of only 1% or 2%? a. hypoxia b. transpiration c. aerobic respiration d. anaerobic respiration
Answer:
A). Hypoxia.
Explanation:
Hypoxia is characterized as the condition in which tissues are deprived of an adequate supply of oxygen. As per this definition, hypoxia would be the process that is most likely to occur in the plant's leaves when it is revealed to a minimum level of 1 or 2% of oxygen. The lack of oxygen in such states reaches the tissues. One of the advanced stages of this process is 'anoxia; where there is a complete absence of 'oxygen' that enhances the ecological stress. Thus, option A is the correct answer.

Answer:
fixed action pattern
Explanation:
This is an example of a fixed action pattern. This is an ethological term that describes an instinctive behavior sequence that is highly stereotyped and species-characteristic due to it happening in the same manner countless times in a predictable cycle. These fixed action patterns are innate mechanisms triggered by a specific stimulus or releaser, which in this scenario is the sight of a red belly.

Define negative feedback of homeostasis
Answer:
A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Nutrition experts recommend that most people eat less than 2,300 milligrams of sodium a day for good heart health. What percentage of this limit did you consume by eating these three foods? Are you surprised by this total? Explain your response. Plato
Explanation:
Sodium intake is important to health and most importantly, it is important to the heart. But excess sodium can lead to serious health issues. Therefore, the intake of sodium should be limited.
As per American Heart Association, an average American consumes more than 3400 mg sodium per day in their food. But the consumption must be limited to 2300 mg.
I am very much surprised to know that I consumed a lot more than this limit of sodium in my daily diet. I take up nearly 200 % of sodium intake. I am surprised by this and very much worried. If I continue to take sodium like this, it will have ill affects on my heart. So, I need to reduce my intake to less than 2300 mg of sodium a day. And also I need to do some cardiovascular exercise regularly.
Answer:
I ate 54% of the daily recommendation just from the pizza. I’m surprised, because even though pizza is a little salty, I didn’t realize it contained that much sodium.

A form of exercise that involves short, intense bursts of energy; anaerobic exercise can only be maintained for 1–2 minutes, slightly longer through specific anaerobic training. Anaerobic exercises are generally used to build muscle mass, increase muscular strength, speed and power, for example sprinting (running, cycling, swimming, etc), and bodybuilding.
A. Anaerobic Exercise
B. Aerobic Exercise
Answer:
A). Anaerobic Exercise.
Explanation:
Anaerobic Exercise is characterized as the exercise that aims to break down glucose without making use of oxygen. Such exercise involves short, quick, and intense bursts of energy with maximum efforts. This leads to the body needing immediate energy(except oxygen) to fuel itself that eventually leads to the break down of glucose. This exercise primarily aims to 'build the mass of the muscles or enhance the muscular strength, through short and intense workouts involving jumping, sprinting, running, cycling, etc. Therefore, option A is the correct answer.

The given question is incomplete, and as there is two steps present in protein synthesis, attaching the the image related the question to answer.
Answer:
The correct answer is : translation.
Explanation:
Translation is the second essential step of the central dogma or the protein synthesis process that is takes place in the ribosomes of the cell, Ribosome reads decode the codon, a sequence of 3 sequence. tRNA comes with the anticodon to the codons that are present on ribosome in order to bind the amino acids to it.
The amino acid that was brought by the tRNA is detaches itself as it bind to the polypeptide chain forming on ribosome to create polypeptide chain, this process repeats itself up-to the stop codon.
Thus, the correct answer is : translation.
