Read the scenario below and answer the questions that follow for 2 points each: Two Siamese and three Persian cats survive a shipwreck and are carried on driftwood to a previously uninhabited tropical island. All five cats have normal ears, but one carries the recessive allele f or folded ears, his genotype is Ff. The other four cats are not carriers, so their genotype is FF. Thus there are 10 total alleles within this population, 9 being F alleles and 1 being f. So, the frequencies are 9/10 or 0.90 for F the allele and 1/10 or 0.10 for the f allele. 1. Identify ONE of the five conditions required for Hardy-Weinberg equilibrium that this population of cats does not meet. 2. If you assume Hardy-Weinberg equilibrium for this population, what would be the frequencies of the two alleles after 10 generations? 3. Knowing that the frequency of the folded ears genotype ff is equal to to the frequency of the f allele squared (0.1 x 0.1), how many cats would have folded ears if after 10 generations there are 2,500 cats on the island?
Answer:
c
Explanation:
According to H-W, a population is in equilibrium if it meets five conditions, and have the same allelic and genotypic frequencies through many generations. 1) Infinite population size / 2) p=0.9 and q=0.1 / 3) 25 cats
-------------------------------------------------------
Let us review some theoretical framework about Hardy-Weinberg equilibrium, while we answer the questions.
⇒ Hardy-Weinberg assumption for a population in equilibrium:
Random matings No superposed generations No mutations No migration Infinite population size ⇒ No genetic drift No natural selectionQ1. Identify ONE of the five conditions required for Hardy-Weinberg equilibrium that this population of cats does not meet.
Since this population is composed of two Siamese and three Persian cats, the condition that this population does not meet is infinite population size.
This population is under the effect of genetic drift for being only 5 individuals colonizing an island.
*****************
⇒ According to Hardy-Weinberg, p and q represent the allelic frequencies in a locus, referring to the allelic dominant or recessive forms.
The genotypic frequencies after one generation are p² (H0m0zyg0us dominant), 2pq (Heter0zyg0us), q² (H0m0zyg0us recessive).
Populations in H-W equilibrium will get the same allelic frequencies generation after generation.
The sum of these allelic frequencies equals 1, this is p + q = 1. The genotypic frequencies sum also equals 1, this is p² + 2pq + q² = 1.
Being
p the dominant allelic frequency, q the recessive allelic frequency, p² the h0m0zyg0us dominant genotypic frequency q² the h0m0zyg0us recessive genotypic frequency 2pq the heter0zyg0us genotypic frequencyQ2. If you assume Hardy-Weinberg equilibrium for this population, what would be the frequencies of the two alleles after 10 generations?
Allelic frequencies, f(x), are
f(F) = p = 0.9f(f) = q = 0.1If this population is in H-W equilibrium, the allelic frequency will be the same through many generations.
So, after 10 generations, the allelic frequencies will still be p = 0.9 and q = 0.1.
Q3. Knowing that the frequency of the folded ears genotype ff is equal to to the frequency of the f allele squared (0.1 x 0.1), how many cats would have folded ears if after 10 generations there are 2,500 cats on the island?
We know that,
f(F) = p = 0.9f(f) = q = 0.1N = 2500 catsTo get the number of individuals with folded phenotype, we should get the phenotypic frequency, which equals the genotypic frequency because it is the recessive phenotype.
Genotypic and Phenotypic Frequency
F(ff) = q² = 0.1 = 0.01Now that we have the phenotypic frequency, we just need to multiply it by the total number of individuals in the population, N.
N = 2500 individuals
Individuals with folded ears = 0.01 x 2500 = 25So, after 10 generations and a population size of 2500 cats, there will be 25 folded-eared individuals.

What unique characteristic does the bonding of carbon to other atoms have and why is this important for organic molecules?
Explanation:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules. Individual carbon atoms have an incomplete outermost electron shell.The ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
The Carbon can form four bond with different atom anf form a long chain of different size. These can also be branched. The long chains are very durable.
Silicon and some other elements can do so but the chains are relatively short and non-durable.

Lucy is traveling to the top of Pike's Peak. The elevation is 14,000 feet. At the base, her respiration rate is 12 breaths per minute. At the top of Pike's Peak, her respiration rate increases to 20 breaths per minute. Why does Lucy's respiration rate most likely increase at the higher elevation
Answer:
Lucy's respiration rate increases because of the decrease in the atmospheric pressure and the partial pressure of O₂.
Explanation:
As Lucy ascends, the atmospheric pressure decreases. The decrease in this pressure decreases the partial pressure of inspired O₂, which causes less oxygen saturation in the blood. As oxygen is essential for the vital functions of the body, the respiratory rate increases to valance the loss of oxygen. In other words, the oxygen that the body had in one inspiration, now it has to obtain with multiple breaths. The same happens with the CO₂ that Lucy expels from her body.

After cytokinesis, how many cells have been formed from the parent cell?
Answer:
The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
Explanation:
The phragmoplast, a structure made up of membranes, actin filaments, and microtubules, controls the deposition of the new wall.
What is the role of cytokinesis in plant cell?Higher plant cells have a unique process for cytokinesis, in which the division of a new cell wall partitions the cytoplasm.
Inside the cell is the cell plate. The location of a preprophase band of microtubules and actin filaments determines where the cell plate is located.
After mitosis, a new cell wall must be created and inserted in plant cells during a process known as cytokinesis.
The cytoplasm of the parent cell is now divided into two daughter cells by a process known as cytokinesis in the cell.

dev, s blood report suggest that the X components in his blood has significant increase because he is suffering from an infection disease. Identify X.
Answer:
The X components of Dev's blood, which increase significantly with infectious disease, are leukocytes.
Explanation:
Leukocytes, also called white blood cells, are the cellular components of the blood that are responsible for the body's defenses and protection.
When a pathogen —usually a bacterium— enters the body, an infectious disease occurs. In response to an infection, white blood cells increase in number in order to fight the infection.
This is why the X component of Dev's blood, leukocytes, increases significantly when Dev has an infectious disease.

Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.

A.
It produces body cells.
B.
It causes alleles to deform.
C.
It prevents genetic mutation.
D.
It produces reproductive cells.
Answer: The correct answer is D. It produces reproductive cells.
Explanation: Confirmed correct.
The statement that best describes the result of meiosis is it produces reproductive cells. The correct option is D.
What is meiosis?Meiosis is a reduction division, thus the sex cells that create the gametes will do so while going through meiosis. The number of chromosomes in the gametes will be halved from that of an adult human.
A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.
Four haploid daughter cells with chromosomal variations from the original parent cell and half as many chromosomes as the original parent cell are the result of meiosis (diploid).
Therefore, the correct option is D. It produces reproductive cells.

Which statement best describes how the environment influences the traits of an individual?
The environment influences the gene expression which can change the genotype.
The environment influences the gene expression which can change the phenotype.
The environment influences only external factors.
The environment influences only internal factors.
Answer: The environment influences the gene expression which can change the phenotype.
Explanation: TRUST
The environment influences the gene expression which can change the genotype. The correct option is A.
What is gene expression?The methodology by which a gene in a cell is activated to produce RNA and proteins.
Gene expression can be assessed by examining the RNA, the protein produced from the RNA, or whatever the protein does in the cell.
The environment can impact gene expression in a life form, along with the outer environment in which the species is positioned or evolves, as well as the organism's internal world, which encompasses factors such as hormones and metabolism.
Several factors influence gene expression, which would include molecules within the cell, mutations that cause dominant damaging consequences and haploinsufficiency, signaling molecules from neighboring cells and the environment, and epistasis.
The environment influences an individual's genotype but not his or her phenotype.
Thus, the correct option is A.
