meron, who is on atight budget, stayed in an inexpensive hotel where she got bitten by bedbugs. now every time she sees a commercial for that hotel, she develops an itch. from this identify the conditional response, conditional stimuli, unconditional response, unconditional stimuli. according to Pavlov .
Answers
Conditional Response: The itch that Meron experiences when she sees a commercial for the hotel is the conditional response.
Conditional Stimulus: The commercial for the hotel serves as the conditional stimulus.
Unconditional Response: The itch that Meron experiences after being bitten by bedbugs is the unconditional response.
Unconditional Stimulus: The bedbug bites that caused Meron to develop an itch serve as the unconditional stimulus.
In this scenario, the conditional response, conditional stimulus, unconditional response, and unconditional stimulus can be identified according to Pavlov's classical conditioning.
Conditional Response: The itch that Meron experiences when she sees a commercial for the hotel is the conditional response. It is a learned response that is triggered by a specific stimulus.
Conditional Stimulus: The commercial for the hotel serves as the conditional stimulus. It is the previously neutral stimulus that, through association with the unconditional stimulus, elicits the conditional response. In this case, the conditional stimulus is the visual or auditory cues associated with the hotel commercial.
Unconditional Response: The itch that Meron experiences after being bitten by bedbugs is the unconditional response. It is an unlearned, natural response that is automatically elicited by the unconditional stimulus.
Unconditional Stimulus: The bedbug bites that caused Meron to develop an itch serve as the unconditional stimulus. It is the stimulus that naturally and automatically triggers the unconditional response, which is the itch.
Through classical conditioning, the conditional stimulus (hotel commercial) becomes associated with the unconditional stimulus (bedbug bites), leading to the development of the conditional response (itch) whenever Meron encounters the conditional stimulus.

The image shows an energy pyramid. Vulture Coyote Prairie dog Grass Which statement about how energy flows through this ecosystem is supported by this ecological pyramid? OA. The highest trophic level has the most available energy because vultures are a tertiary consumer. B. The organisms of the second trophic level obtain their energy from the coyotes located in the third trophic level. C. The grasses' trophic level has the most energy, but only some of that energy moves to the second trophic level. D. The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.
Answers
The third trophic level is made up of prairie dogs that get their matter and energy from the grasses (option d).
The energy pyramid depicted in the image illustrates the flow of energy through an ecosystem. In an energy pyramid, each level represents a trophic level, indicating the position of organisms in a food chain. The pyramid narrows as it ascends, indicating the decrease in available energy at higher trophic levels.
In this specific pyramid, the lowest trophic level is occupied by the grass. This makes sense because grass is a producer that captures energy from the sun through photosynthesis. As a result, it possesses the most energy within the ecosystem.
Moving up the pyramid, the second trophic level is occupied by the prairie dogs. They are herbivores that primarily consume grass for their energy needs. This demonstrates that the prairie dogs acquire their matter and energy from the grasses, supporting option D.
The third trophic level contains the coyotes, which are tertiary consumers. Tertiary consumers feed on other consumers, not producers. Therefore, option A is incorrect since vultures, not coyotes, are tertiary consumers in this ecosystem.
Option B is also incorrect because the coyotes do not obtain their energy from other coyotes located in the third trophic level. They acquire their energy indirectly from the grasses through the prairie dogs.
Finally, option C is incorrect as it states that the grasses' trophic level has the most energy. While the grasses are indeed the primary producers and possess the most energy, not all of that energy moves to the second trophic level.
Thus, the correct statement supported by the ecological pyramid is option D: The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

1 What does the codon sequence on the mRNA strand determine?
A The gene sequence of the DNA
B The amino acid sequence of the polypeptide
C The codon that is signaled
D The signaling sequence
2 What portion of the DNA is also known as a gene?
A The coding sections
B The non-coding sections
C The mRNA strand
D The polypeptide sequence
Answers
1. The correct answer is B.
2. The correct answer is A.
The codon sequence on the mRNA strand determines the amino acid sequence of the polypeptide.
The coding section is the portion of the DNA that is also known as a gene. Genes are the functional units of DNA that provide the instructions for making proteins. They are composed of coding cells, also known as exons, that contain the information needed to build the polypeptide, and non-coding sections, also known as introns, that do not.
The codon sequence on the mRNA strand is translated by the ribosome during protein synthesis. Each codon, which is a sequence of three nucleotides, corresponds to a specific amino acid. The ribosome reads the codon sequence on the mRNA strand and adds the corresponding amino acids to the growing polypeptide chain. This process is called translation.
In DNA, genetic information is encoded in the sequence of nucleotides, which are the building blocks of DNA. Genes are specific segments of DNA that contain the instructions for making a specific protein. These instructions are encoded in the sequence of nucleotides within the coding sections of the DNA, also known as exons. The non-coding sections, also known as introns, do not contain instructions for making proteins, but they play important roles in the regulation of gene expression.

Calculate the equilibrium genotype frequencies from a population with allele frequencies p=.25 and q=.75
Answers
There are 6.25% homozygous dominant people (AA), 37.5% heterozygous people (Aa), and 56.25% homozygous recessive people (aa).
How to determine equilibrium genotype frequencies?In a population with two alleles, p and q, the frequency of p and q must add up to 1, or 100%. In this case, p = 0.25 and q = 0.75.
Using the Hardy-Weinberg equation, we can calculate the expected frequencies of the three possible genotypes: AA, Aa, and aa. The equation is:
p² + 2pq + q² = 1
where p² represents the frequency of the AA genotype, 2pq represents the frequency of the Aa genotype, and q² represents the frequency of the aa genotype.
Substituting the given values of p and q:
(0.25)² + 2(0.25)(0.75) + (0.75)² = 1
0.0625 + 0.375 + 0.5625 = 1
Therefore, the expected frequencies of the three genotypes are:
AA = p² = (0.25)² = 0.0625
Aa = 2pq = 2(0.25)(0.75) = 0.375
aa = q² = (0.75)² = 0.5625
So in this population, we would expect to see 6.25% homozygous dominant individuals (AA), 37.5% heterozygous individuals (Aa), and 56.25% homozygous recessive individuals (aa).

Explanation:
A motor unit is made up of a motor neurone and all the muscle fibre it supplies nerve to.
Within a muscle, the muscle fibers are functionally organized as MOTOR UNITS within a muscle.
MOTOR RECRUITMENT causes an increase in muscle tension which occurs when there is an increased number of stimulated motor units.
During a muscle contraction, the weakest motor units are recruited to contract first,The more weight (resistance) you add to a muscle, the more motor units you will need to recruit in order to generate movement.Recruitment stops as soon as movement starts, result is a smooth, even muscle contraction.
