which of the following is not true of genetic drift: group of answer choices a. it occurs when no allele is advantageous b. it refers to random changes to allele frequencies c. it works faster in large populations d. it doesn't apply to genes, only alleles
d.It doesn't apply to genes,only alleles. The random process of alleles being transferred from parents to offspring is known as genetic drift.
A population must add more alleles to increase genetic diversity, which can only happen through mutations or the influx of unrelated individuals. Only the way that already existing alleles are passed down is impacted by genetic drift.
The likelihood of an allele being passed down to succeeding generations is higher for those with high baseline frequencies than for those with lower baseline frequencies. A high-frequency allele may eventually reach 100% frequency by chance, becoming fixed in the population. If none of the few parents who carry that allele chance to pass it on to their children, a low-frequency allele may eventually vanish from the population.

Answer:
B. tires are to a car.
Explanation:
Ribosomes are to Rough Endoplasmic Reticulum as tires are to a car. So the correct option is B.
What are ribosomes?
The biological machinery that produces proteins is called a ribosome. Each cell has several ribosomes, which are each composed of two subunits. These two subunits form a tight seal around the messenger RNA molecule before moving down its length and reading each three-letter codon.
The transfer RNA, whose base sequence matches that of the messenger RNA, docks to the ribosome. A specific amino acid can be added to the end of the expanding protein chain by pairing each three-letter messenger RNA codon with the corresponding anticodon on a particular transfer RNA. Once the protein is finished, the ribosome fragments.
The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.
Therefore the correct option is B.

Which of the following models represents an atom that is most likely to form a cation with a charge of +1?
The atom represented by the model with one valence electron in its outermost shell is most likely to have the lowest ionization energy and hence is most likely to form a cation with a charge of +1.
The atom that has the lowest ionization energy is the one which is most likely to form a cation with a charge of +1. Ionization energy is defined as the energy required to remove an electron from an atom or ion in the gaseous state. Therefore, an atom with a low ionization energy requires less energy to remove its outermost electron and form a positively charged cation.
Among the models of atoms given, the atom represented by the model with one valence electron in its outermost shell is most likely to have the lowest ionization energy. This is because the valence electron is loosely held by the nucleus due to its large distance from it. As a result, it requires less energy to remove the outermost electron and form a cation with a charge of +1.
For example, Lithium (Li) has one valence electron in its outermost shell and has the lowest ionization energy among the elements in the first group. This makes it easy for Lithium to lose its valence electron and form a cation with a charge of +1.
In summary, an atom with a low ionization energy requires less energy to remove its outermost electron and form a positively charged cation.

O both a & b
Behaviors associated with cancer(s) are Oprtion D, Both a& b. Option A, identified by Lydia Temoshok, and Option B, very, very nice people, stoic, non-emotional.
Lydia Temoshok, a researcher in psychoneuroimmunology, has identified various behavioral patterns that can be associated with cancer. However, it is important to note that these patterns are not exclusive to all individuals with cancer. Cancer affects people from all walks of life, and their behaviors can vary significantly.
Some individuals diagnosed with cancer may exhibit certain behavioral tendencies that could be categorized as "very, very nice people, stoic, and non-emotional." These individuals may approach their diagnosis and treatment with a sense of calmness, resilience, and a desire to maintain a positive outlook. They may choose to internalize their emotions and focus on staying strong for themselves and their loved ones.
On the other hand, it is crucial to recognize that cancer can also elicit a range of emotional responses in individuals, leading to behaviors that may differ from the aforementioned stereotype. Some people may experience heightened emotional states, such as fear, anxiety, sadness, or anger. They may express their emotions more openly and seek support from others. It is essential to understand that these responses are valid and normal in the face of a challenging and life-altering diagnosis.
Ultimately, cancer-related behaviors are highly individualized and cannot be generalized across all people with cancer. Each person's experience is unique, and their behaviors may be influenced by various factors such as personality, coping mechanisms, support systems, and personal circumstances. It is important to approach individuals with cancer with empathy, understanding, and an open mind, acknowledging and respecting the diversity of responses and emotions they may exhibit.

you have removed a volume of a culture of e. coli during exponential growth in order to measure the viable cell count. if the absorbance reading was 0.5, estimate the maximum dilution factor you would need in order to obtain between 30 and 300 colonies on a plate spread with 0.1 ml of the dilution. assume that there are 10^7 cells/ml in one absorbance unit.
The third dilution will give us a number of cells within the countable range of 30 to 300 colonies on a plate. Therefore, the maximum dilution factor we need is 1:1000 (three 1:10 dilutions).
As per the question given,
To estimate the maximum dilution factor needed, we need to calculate the number of cells in the original culture volume and determine how many dilutions we need to perform to get a countable number of cells.
Calculate the number of cells in the original culture volume:
If the absorbance reading was 0.5, we can use the conversion factor of 10^7 cells/mL per unit of absorbance to calculate the cell density:
Cell density = 0.5 x 10^7 cells/mL = 5 x 10^6 cells/mL
If we assume that we removed 1 mL of culture for counting, then the number of cells in that volume is:
Number of cells = Cell density x Volume = 5 x 10^6 cells/mL x 1 mL = 5 x 10^6 cells
Determine the appropriate dilution factor:
To get between 30 and 300 colonies on a plate, we need to spread a dilution that contains between 30 x 0.1 = 3 and 300 x 0.1 = 30 cells on the plate. Therefore, we need to dilute the original sample to obtain a concentration of cells that falls within this range.
Let's assume that we want to use a 1:10 dilution series. We can calculate the number of cells that will be present in each dilution as follows:
Dilution factor = 1:10
Number of cells in first dilution = 5 x 10^6 cells / 10 = 5 x 10^5 cells/mL
Number of cells in second dilution = 5 x 10^5 cells/mL / 10 = 5 x 10^4 cells/mL
Number of cells in third dilution = 5 x 10^4 cells/mL / 10 = 5 x 10^3 cells/mL
To check if this dilution series will give us a countable number of cells, we can calculate the number of cells that will be present on the plate after spreading 0.1 mL of each dilution:
Number of cells on plate for first dilution = 5 x 10^5 cells/mL x 0.1 mL = 5 x 10^4 cells
Number of cells on plate for second dilution = 5 x 10^4 cells/mL x 0.1 mL = 5 x 10^3 cells
Number of cells on plate for third dilution = 5 x 10^3 cells/mL x 0.1 mL = 5 x 10^2 cells
Based on this calculation, the third dilution will give us a number of cells within the countable range of 30 to 300 colonies on a plate. Therefore, the maximum dilution factor we need is 1:1000 (three 1:10 dilutions).

which two sentences best describe the role of the setting in the story
Answer: Hello There!...................
The setting helps reveal the speaker's joyous attitude.
The setting helps develop the theme of freedom in the story.
Explanation:
Mark me brainest please. Hope this helps. Anna ♥
Explanation:
Setting is one of the elements of a story. It is the context that surrounds the story - be it fiction or non-fiction -, its time and place. It usually takes one of three forms: an outdoor place, such as a forest; a public or private place that has some importance for the characters, such as a house or a park; the cultural and historical background, which helps readers understand what sort of influences that characters were under.
Thus, the setting is a vital element to convey ideas and theme, as well as create the mood and emotional response for readers. The setting can be so important in a narrative that it may become a character in itself. In Edgar Allan Poe's "The Fall of the House of Usher", for example, the house where Usher lives influences him and the narrator. It's as if the house is alive, haunted, driving those who stay in it to madness. Without the proper setting, however, this story wouldn't provoke the same emotional response in readers - fear, suspense etc.

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :
p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7
p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6
p5p5, p5p4, p5p3, p5p2, p5p1 - 5
p4p4, p4p3, p4p2, p4p1 - 4

In a population the homozygous dominant individual make up 70% of the population while heterozygous ones made up 21% and recessive made up 9%. What are the frequencies of the A and a alleles?
There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.
The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.
The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).
We know that the frequency of heterozygotes is 0.21, or 21%.
Plugging in the known values:
2 * 0.7 * q = 0.21
Solving for q:
q = 0.15
So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.
