The term for the comparison of amino acid sequences between species is "sequence alignment."
Sequence alignment is the process of comparing the sequences of nucleotides or amino acids of two or more biological sequences to determine their degree of similarity or difference.
Amino acid sequences are the linear arrangements of the building blocks of proteins, and they play a critical role in determining the structure and function of proteins.
By comparing the amino acid sequences of proteins in different species, scientists can gain insight into evolutionary relationships and infer the functions of newly discovered proteins based on their similarity to known proteins.
Sequence alignment can be performed manually or with specialized computer algorithms that can rapidly compare thousands of sequences.
The output of sequence alignment is typically presented as a diagram that shows the positions of conserved residues and gaps between the sequences.

Suppose there are 70 bacteria in a Petri dish at start time. Nine hours later, there are 230 bacteria in the dish. 1.) Express the number of bacteria, P, as a function of t hours passed. Note: Round the growth rate to 4 dec. places. P(t)= 2.) Use the model from part a to determine the number of bacteria, rounded to a whole number, in the dish after 14 hours:
The number of bacteria in the dish after 14 hours, rounded to the nearest whole number, is approximately 946.
1.) To express the number of bacteria, P, as a function of time, t, we can use the exponential growth formula:
P(t) = P0 * e^(rt)
Where P0 is the initial number of bacteria, r is the growth rate, and e is the base of the natural logarithm.
Given that there are 70 bacteria initially and 230 bacteria after 9 hours, we can use these data to find the growth rate, r. Rearranging the formula:
r = ln(P(t)/P0) / t
Substituting the values:
r = ln(230/70) / 9
After performing the calculations, the growth rate is approximately 0.2275 (rounded to 4 decimal places).
Therefore, the function representing the number of bacteria, P, as a function of time, t, is:
P(t) = 70 * e^(0.2275t)
2.) To determine the number of bacteria in the dish after 14 hours using the model obtained in part 1, we substitute t = 14 into the equation:
P(14) = 70 * e^(0.2275 * 14)
P(14) = 946

Do you think an allele frequency of 1 is beneficial or harmful to the species?
An allele frequency of 1 is beneficial or harmful to the species and is increased from generation to generation.
Detrimental mutations are lost because they reduce an individual's fitness. If a mutation improves fitness the frequency of that allele increases from generation to generation. Allele frequencies reflect genetic diversity. Changes in allele frequencies over time may indicate that genetic drift is occurring or that new mutations have been introduced into the population.
An association with a beneficial allele may also carry a deleterious allele. The inability of natural selection to eliminate geriatric diseases is a reminder that successful fitness does not equate to the absence of disease. Dominant alleles always have a direct effect on phenotype, so they tend to be highly selected. However, even deleterious dominant alleles can persist in the population's gene pool.

what would happen to a moss sporophyte of the gametophyte that produces it died
If the gametophyte of a moss dies, the sporophyte it produced will also die. The sporophyte is dependent on the gametophyte for nutrition and support, as it remains attached to it throughout its entire life cycle.
The gametophyte of a moss produces the sporophyte through the process of fertilization. The sporophyte remains attached to the gametophyte and receives nutrients from it through a specialized structure called the foot. The sporophyte also depends on the gametophyte for support, as it lacks the ability to produce its own food through photosynthesis. Therefore, if the gametophyte dies, the sporophyte will no longer receive the nutrients and support it needs to survive, and it will ultimately perish.
In summary, the sporophyte of a moss is completely dependent on the gametophyte for survival. If the gametophyte dies, the sporophyte will also die as a result.

To most humans, the chemical PTC tastes very bitter. The ability to taste it is a dominant trait. People who can’t taste PTC exhibit the recessive trait. Which genotype represents people who can’t taste the chemical?
The ability to taste the chemical PTC (phenylthiocarbamide) is determined by a single gene, TAS2R38, on chromosome 7. This gene codes for a taste receptor on the tongue that is sensitive to PTC.
The dominant allele (T) produces a functional receptor that can detect the bitter taste of PTC, while the recessive allele (t) produces a non-functional receptor that cannot detect the taste of PTC.
Therefore, individuals who can't taste the chemical PTC exhibit the recessive trait and have a homozygous recessive genotype (tt), as they have two copies of the non-functional allele. In contrast, individuals who can taste PTC can have either a homozygous dominant genotype (TT) or a heterozygous genotype (Tt).
This trait has been studied extensively in genetics research due to its simple inheritance pattern and high frequency of variation in human populations. It is estimated that approximately 25-30% of people worldwide are unable to taste PTC due to their homozygous recessive genotype.

What is a codon and what is its role in protein synthesis?
A codon is a DNA or RNA sequence of three nucleotides that serves as a unit of genomic information and codes for a specific amino acid or signals the end of protein production.
Any of the 64 distinct DNA sequences of three consecutive nucleotides that either encode information for the creation of a particular amino acid or act as a stop signal to end translation are referred to as codons in genetics (protein synthesis). Adenine (A), guanine (G), cytosine (C), and uracil (U) are the four nitrogenous bases that make up codons (U). The 20 amino acids that make up proteins are specified by 61 of the 64 available codon sequences, while three are stop signals.In the process of protein synthesis, polypeptide chains are created inside of cells using programmed combinations of individual amino acids. A coded sequence, enzymes, and messenger, ribosomal, and transfer ribonucleic acids are necessary for the creation of new polypeptides (RNAs).

Proto-oncogenes need or demand only "one" allele (gene copy or variant) to be altered in order to cause cancer (changes in the deoxyribonucleic acid or DNA). One allele is all that is required for a proto-oncogene to develop into an oncogene that causes cancer. Since only one allele (or gene copy) is required to create an oncogene that induces cellular transformation and resulting in cancer, it is referred to as a "dominant" mutation. This type of mutation causes a "gain" in function since the affected cells can now divide uncontrollably and serve a new purpose.

the natural expression of individual differences in self-reported level of response to alcohol during ecologically-assessed drinking episodes.
The natural expression of individual differences in self-reported level of response to alcohol during ecologically-assessed drinking episodes refers to the variability observed among individuals in how they subjectively experience and respond to alcohol when consumed in real-world settings.
When individuals consume alcohol, their subjective experiences can vary widely, including differences in their perceptions of the effects, their tolerance levels, and their overall sensitivity to alcohol.
These individual differences can be influenced by various factors, such as genetic predispositions, physiological characteristics, previous alcohol exposure, and personal expectations.
Ecologically-assessed drinking episodes involve the assessment of alcohol consumption and its effects in real-world settings, such as bars, parties, or social gatherings. This approach allows researchers to study individuals' responses to alcohol in their natural environments, capturing the complexity and variability of real-life drinking situations.
Self-report measures are commonly used to assess an individual's level of response to alcohol during ecologically-assessed drinking episodes. These measures typically involve individuals providing subjective ratings or descriptions of their experiences, including how intoxicated they feel, their mood changes, cognitive impairments, and other perceived effects of alcohol.
By studying individual differences in self-reported level of response to alcohol in ecologically-assessed drinking episodes, researchers aim to better understand the factors that contribute to alcohol-related behaviors and consequences. This knowledge can help inform interventions and strategies for preventing and addressing alcohol-related problems, such as developing personalized interventions based on an individual's unique response to alcohol.

Why does genetic variety happen? What does it entail?Gene variants, commonly referred to as mutations, and a natural process in which genetic information is reorganised as a cell prepares to divide can both result in genetic differences (known as genetic recombination). Genetic changes that affect gene activity or protein function can give an organism distinct features.
Some organisms can survive in their environment more successfully than others due to genetic variety in a group of species. Even among a small population of organisms, there can be dramatic differences in how well-suited they are to a given habitat.

Some cells can die as a result of external agents suck as poison or trauma. However, most cells die through a process known as apoptosis, or programmed cell death. What is a likely consequence of a mutation that prevents apoptosis
Answer: A tumor
Explanation:
A mutation that prevents apoptosis can disrupt the normal cellular mechanisms that prevent tumor formation, and lead to the uncontrolled growth of cells that could ultimately cause cancer.
What is apoptosis?A mutation that prevents apoptosis, or programmed cell death, can have several consequences. One of the most significant consequences is the accumulation of damaged or abnormal cells, which can lead to the development of tumors and cancer. Apoptosis is a natural process that eliminates cells that are no longer needed or that are damaged beyond repair. This process is essential for maintaining tissue homeostasis and preventing the growth of abnormal cells.
When cells are prevented from undergoing apoptosis, they may continue to divide and proliferate uncontrollably, leading to the formation of a mass of cells known as a tumor. This is because cells that have undergone DNA damage or that have other abnormalities are normally eliminated through apoptosis to prevent the accumulation of cells that could become cancerous.
