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?

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.

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Answers
Answer:
tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres
Explanation:
En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.

If an organism had 20 chromosomes, how many chromosomes would the daughter cell have after mitosis? After meiosis?
Answers
Answer:
After mitosis, the daughter cell has 20 chromosomes and after meiosis, the daughter cell has 10 chromosomes.
So the answer is 20 and 10
Answer:
[tex]\boxed {\boxed {\sf Mitosis: 20 \ chromosomes}}[/tex]
[tex]\boxed {\boxed {\sf Meiosis: 10 \ chromosomes}}[/tex]
Explanation:
Mitosis and meiosis are both types of cell divisions, but they are different.
Mitosis
1 cell division that results in 2 daughter cells used for growth, repair, and developmentThe cells are genetically identical with the same number of chromosomes as the parent cell.Meiosis
2 cell divisions resulting in 4 daughter cells for sexual reproduction The cells are genetically different and have half the number of chromosomes as the parent.The organism has 20 chromosomes.
Mitosis: same number of chromosomes=20 Meiosis: half the chromosomes= 20/2= 10After mitosis, the daughter cell has 20 chromosomes. After meiosis, the cell has 10.
After cytokinesis, how many cells have been formed from the parent cell?
Answers
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.
Therefore, each daughter cell is haploid and has just one set of chromosomes, or half as many as the original cell.

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)
Answers
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.

What unique characteristic does the bonding of carbon to other atoms have and why is this important for organic molecules?
Answers
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.
Therefore, the ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
