The diagram represents a food pyramid. The concentration of the pesticide DDT in individual
organisms at level D is higher than the concentration in individuals at level A because DDT is
A. produced by organisms at level C ingested by
those in level D.
B. passed through levels A, B, and C to organisms
at level D.
C. excreted by organisms at level A as a toxic
waste.
D. synthesized by organisms at level D.
Answer:
B. passed through levels A, B, and C to organisms
Explanation:
DDT is an insecticide that passed through the food chain from one trophic level to the next.
The concentration of DDT increases with the each trophic level in food chain and the amount of toxin increases as passes from A to B, B to C, and C to D where D has the higher concentration of DDT as it is the higher trophic level than A, B, and C.
Hence, the correct answer is "B. passed through levels A, B, and C to organisms".
By 1884, extensive hunting reduced the number of Northern elephant seals to fewer than 100. The extremely limited genetic variation in these seals is consistent with which genetic effect?
Answer:
Genetic drift, specifically the Bottleneck effect.
Explanation:
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
The bottleneck effect is a special case of genetic drift, which is most likely to affect smaller populations. In the exposed example, extensive hunting reduced the number of Northern elephant seals, reducing the number of individuals to fewer than 100. This population experienced one or many generations of very small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered, but the genetic pool might have not.
_________ is (are) the product of Transcription, and the starting material of Translation. A. tRNA B. Amino Acids C. mRNA D. Ribosomes
Answer:
C. mRNA
Explanation:
Hello,
In this case, we may remember that when DNA is undergoing transcription a specific sequence is copied via the RNA polymerase in order to produce the messenger RNA which is subsequently used as the starting material of translation for the protein synthesis as shown on the attached picture. Thereby, answer is C. mRNA, since the transcription process produces it and then, for the translation process, it contains the codons which promote the formation of polypeptides (proteins) via the connection of the anti-codons contained in the tRNA which also provide the amino acids for the polypeptides formation.

The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.
The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell with the use of ATP molecules.
In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.
https://brainly.com/question/24347696
Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.
Explanation:
The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.

The term voltage describes the:
-electrical potential difference between two points.
-likelihood that an electrochemical gradient will develop.
-process of molecules moving from an area of high concentration to low
concentration.
-way in which osmosis determines water movement.
Answer:
electrical potential difference between two points.
Explanation
Voltage refers to the electrical potential difference between two distinct points. It doesn’t describe the way in which osmosis determines water movement (osmotic pressure), nor does it describe the process of molecules moving from an area of high concentration to low concentration (diffusion), or the likelihood that an electrochemical gradient will develop.
The term voltage describes the electrical potential difference between two points. Option A is correct.
Voltage is a measure of the amount of energy that is available to move electrons from one point to another. It is measured in volts (V). The higher the voltage, the more energy is available to move electrons.
The electrical potential difference between two points is created by the difference in the number of electrons at those two points. If there are more electrons at one point than at another, there will be a voltage difference between the two points. This voltage difference will cause electrons to flow from the point with more electrons to the point with fewer electrons. Option A is correct.

Provides information about the rate and change of the stimulus. f. The action potential is generated for a short time period.
Answer:
For this receptor, the stimulus begins with an explosion of action potentials.
that would be the correct option.
Explanation:
A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.
Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.
It keeps the nervous system constantly active in the environment that surrounds it.
They are slowly adaptable, an example of these receptors are the merkel and ruffini receptors.

The animals used in an experiment that involves USDA pain category B, C, and D activities performed on the same animal should be categorized to USDA category D.
The USDA pain categories are used to categorize the level of pain an animal used in testing and research will be exposed to. The categories are as follows:
USDA B: the animal will not feel pain of any kindUSDA C: the animal will feel the occasional slight painUSDA D: Painful procedures that will be mitigated by pharmaceuticals.USDA E: Painful procedures that will not be mitigated.Category B states the animal will not feel pain. Animals in this category are often used for breeding, which is a natural process that does not cause animal distress or pain.
Animals in category C may feel the occasional slight pain which is allowed to subside naturally without the use of pharmaceuticals. This may include procedures such as
Drawing blood samplesInjectionsAnimals in category D are exposed to painful or stressful procedures and will receive anesthetics and other chemical agents to mitigate or completely relieve the pain, Whereas E category animals do not receive said assistance.
These categories follow a strict rule. Animals must be categorized according to the most painful procedure it will undergo, so because the experiment will use USDA B, C, and D procedures, the animals must be placed into USDA category D.

A. There will be no difference as compared to an area that has saprotrophs and detritivores. •
B. There would be nothing left, it will have completely decomposed. •
C. The body would remain, and be just as it was when it died except for weathering. •
D. The body would be decomposing at about half the normal speed.
The correct option is C.
The body would remain, and be just as it was when it died except for weathering.
Explanation:
"If an organism were to die in an environment that had no saprotrophs or detritivores, The body would remain, and be just as it was when it died except for weathering because detrivores and feed on organic matter and excrete the nutrients, without detrivores and saprotroph the the organic matter in the dead organisms will still remain the same.
Detrivores are organisms that feed on dead organic matter and releasing nutrients to the ecosystem through it's wastes.
Saprotroph are decomposers that survive on or in dead organic matter secreting enzymes and releasing nutrients to the ecosystem. Examples is fungi.
Without detrivore and and saprotroph the dead organisms will remain the same except from weathering be side weathering is carried out through the activities of air, water or some agents.

This is incomplete dominance of genes.
Q1 What type of a breeding is this? (monohybrid, dihybrid or interspecific)
Q2 Draw a genetic chart to show P, F1 and F2 generations clearly indicating genotypes, phenotypes and generations.
Answer:
See the answer below
Explanation:
1. This is an example of monohybrid breeding. A monohybrid breeding is the type of breeding that involves parents with a pair of contrasting characters. On the other hand, a type of breeding involving a single gene is what is known as monohybrid breeding.
2. When a red flower snapdragon is crossed with a white flower snapdragon, the resulting offspring are usually pink - an indication of incomplete dominance of the gene responsible for flower color. Assuming the red flower's genotype is AA and that of the white flower is aa:
AA x aa
Aa Aa Aa Aa
F1 genotype = all Aa
F1 phenotype = pink flower
At F2:
Aa x Aa
AA 2Aa aa
F2 Genotype/phenotype:
1AA - red color
2Aa - pink flower color
1 aa - white flower color.

Which of the following is responsible for the conversion of covalently closed circular DNA to supercoiled DNA of the plasmid of: a) endonuclease b) DNA gynase c) topa isomerase d) exonuclease
Answer:
DNA gyrase
Explanation:
DNA gyrase is a bacterial enzyme that plays an important role in catalyzing the negative supercoiling of circular chromosomal DNA. This enzyme belongs to a class of enzymes called topoisomerases which play a major role in transitioning of DNA structure. DNA gyrase conversion of covalently closed circular DNA to supercoiled DNA is ATP-dependent.
The importance of DNA gyrase cannot be overemphasized, because for DNA synthesis to occur, the DNA must have a single-stranded template, hence, DNA gyrase play an important role in unwinding the double-stranded DNA for replication. It has the ability to introduce negative supercoils and relax positive supercoils prior to replication.
What is the effect of these currents on Earth's temperatures?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
