Limiting factors are the biotic and abiotic environmental elements that model a species  population size affecting their carrying capacity. 1) alligators and mosquitoes 2) pollution 3) alligators 4) pollution 5) frogs are control species 6) + alligators, - frogs // + mosquitoes, + frogs.

Limiting factors are all the environmental elements, biotic and abiotic, that act directly on populations and individuals, limiting their distribution and growth.

These factors affect the carrying capacity, influencing on natality and mortality rate, migration, etcetera.

In the exposed example, limiting factors are

These three elements model the Frog population size according to their magnitude and population sizes.

Two simulations per factor were performed in order to see how much each factor affected the frog's populations.

The data chart shows the following tendency,

Alligators

- Low number of alligators →  there was an increase in frogs number from  

                                                10 to 18.

- High number of alligators →  there was a decrease in frogs number from  

                                                 10 to 3.

Pollution

- Low pollution level →  there was no change in frogs number

- High pollution level →  there was a decrease in frogs number from  

                                        10 to 7.

Mosquitoes

- Low number of mosquitoes →  there was a decrease in frogs number

                                                     from 10 to 5.

- High number of mosquitoes → there was an increase in frogs number  

                                                      from 10 to 17.

Information from the graph expresses thesame tendency,

Alligators

- Low number of alligators →  there was an increase from 50k to 90k.

- High number of alligators →  there was a decrease from 50k to 10k.

Pollution

- Low pollution level →  there was no change

- High pollution level →  there was a decrease from 50k to 35k.

Mosquitoes

- Low number of mosquitoes →  there was a decrease from 50k to 25k.

- High number of mosquitoes → there was an increase from 50k to 85k.

1. Which limiting factor(s) in this lab simulation are biotic?

Pollution

3. Which limiting factor impacted the cricket frog population the most? Use evidence to support your answer.

According to the chart and to the graph, the presence/absence of predators impacted the most on the frogs population.

4. Which limiting factor impacted the cricket frog population the least? Use evidence to support your answer.

Pollution is the factor that least affected the frogs population size.

5. Mosquitoes can carry and transmit disease to animals and humans. Explain how the cricket frog plays an important role in limiting the spread of mosquito-borne illnesses like West Nile virus and malaria.

Since frogs feed on mosquitoes, they become a natural control species for the mosquitoes, limiting their spread and effects on humans and animals.

Frogs are a biotic limiting factor for moesquitoes population.

Small amounts of ghrelin are also released by the small intestine, pancreas, and brain. Ghrelin is primarily produced and released by the stomach.

Ghrelin serves a variety of purposes. Because it stimulates appetite, increases food intake, and encourages fat storage, it is known as the "hunger hormone." The peptide known as ghrelin, or the "hunger hormone," is produced by ghrelin cells in the gastrointestinal tract and acts as a neuropeptide in the central nervous system. Ghrelin controls both the distribution and rate of use of energy in addition to controlling hunger. Ghrelin is secreted when the stomach is empty. Your stomach produces the hormone ghrelin. When your stomach is empty, ghrelin is released to tell your brain that it is time to eat.

Jackrabbits' large ears are an adaptation for dissipating heat.

Jackrabbits inhabit desert environments where the days are quite warm. Their ears are a coping mechanism for the heat in the desert. Depending on the temperature, a network of blood arteries in the big, thin ears regulates blood flow. They have quite large ears. A jackrabbit's ears are undoubtedly good listeners, but they also serve as radiators.

They enhance blood flow via the ears to remove heat after a race and on warm days. They reduce blood flow through the ears at night to keep you warm and also increase blood flow via the ears to eliminate heat after a race.

Meiosis is a specialized type of cell division that produces cells that are genetically different from each other.

Cell division is the process through which all cells are created from other cells. Meiosis is a specific type of cell division that generates reproductive cells like sperm and egg cells as well as plant and fungus spores. A "parent" cell generally divides into two or more "daughter" cells during this process. The parent cell can transmit its genetic material in this manner from generation to generation.

Meiosis is a specific type of cell division that takes place in sexually reproducing organisms. It generates reproductive cells like sperm, egg, and spores in plants and fungi, as was previously indicated. In humans, germ cells go through a process called meiosis to develop into sperm or eggs.

The percentage of the homozygous dominant genotype is 0.04 or 4%

An important fundamental principle of population genetics is the Hardy-Weinberg Equilibrium (HWE), which states that "genotype frequencies in a population remain constant between generations in the absence of disturbance by external factors."

if, [tex]p^{2}[/tex]   = 64% = 0.64

Therefore, the percentage of the recessive allele in the population,

q = 0.8

Since, p + q = 1, the percentage of the dominant allele in the population, p = 0.2

Now, the percentage of homozygous dominant genotype in the population,[tex]p^{2}[/tex] = [tex](0.2)^{2}[/tex] = 0.04 or 4%

the percentage of heterozygous genotype, 2pq = 2(0.8)(0.2) = 0.32 or 32%

(complete question)

The percentage of homozygous recessive individuals (for one particular trait) in a population is found to be 64%. Assuming the population is at Hardy Weinberg equilibrium, what is the proportion of the heterozygous genotype? (give your answer as a decimal between 0-1)

p+q=1(p= freq. of dominant allele, q= freq. of recessive allele)

In muscles, the source of ATP depends on the duration of exercise.

The duration of exercise is an important factor in determining the source from which ATP is derived in the muscles.

Initially, when there is enough supply of oxygen, the body will use the method of aerobic respiration for the production of ATP. By the aerobic method, carbohydrates, fats and proteins derived from the food can be used as an energy source.

When the time duration increases, the muscles will switch to anaerobic respiration as there will not be a shortage of oxygen. In this case, energy will be derived from glucose that we get from the breakdown of glycogen. Glycogen is the form in which energy is stored in the body.
