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?
Answers
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.
A red flower producing snapdragon plant is crossed with a white flower producing snapgragon plant. Resulting F1 generation is crossed with one another to produce F2 generation.
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.
Answers
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.
It works because your brain creates images from dots. That’s how you can watch shows that you like a whole lot.
Answers
Answer:
The fovea works because your brain creates images from points.
Explanation:
The fovea is located in the center of the eye's retina. It is the structure capable of capturing stitches from what you are viewing and sending those stitches to the brain, which will "stitch" all stitches together and form an image. In summary, the fovea is able to project an image to the brain through pieces of the image, it is formed by cones that allow the transmission of light to the photoreceptors of the eyes.
The fovea works since your brain makes pictures from points.

Answer: The options are not given, here are the options.
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.

_________ is (are) the product of Transcription, and the starting material of Translation. A. tRNA B. Amino Acids C. mRNA D. Ribosomes
Answers
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 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.
Answers
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.

An investigator wishes to use animals in an experiment that involves USDA pain category B, C, and D activities performed on the same animal. How should the animal be categorized
Answers
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.

Answers
Answer: Actually the answer is D. It is supposed to be identical to the original, that is why it can be a substitute.
Explanation: I just took the test, this is 100% correct.
Brainliest please?
The sequence that shows substitution mutation is the sequence in option D.
What are the nucleotide bases?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.
The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine. But in RNA, it is uracil with adenine. Guanine and cytosine are the same. So the adjacent base pairs will be adenine and uracil.
Therefore, the correct option is a sequence in option D.

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
Answers
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.
