How might you model the relationship between a tomato plant and the hornworm caterpillar? Identify the components of the model including inputs and outputs
Answer:
Parasitism.
Explanation:
The relationship between a tomato plant and the hornworm caterpillar is parasitism because parasitism is a type of symbiotic relationship in which one organism get benefits and the other get harmed. We know that hornworm caterpillar feed on leaves and destroy the tomato crop. So it gets nutrients from tomato plant and the tomato plant is negatively affected. The input of this system is the vegetative part of tomato plant while the output is the conversion of hornworm caterpillar into a moth.

Answer:
Competition
Explanation:
Took the quiz
If two trees are growing close to each other with both using light, water, and the same nutrients in the soil, the relationship is best defined as competition. the correct option would be B.
In other words, biological competition describes a form of relationship between two organisms in which both fight for the same resources that are available in limited supply.
in competition, both organisms either learn to coexist through resource partitioning or fight it to finish. Without resource partitioning, one of the organisms will have to die as a result of being outcompeted.

Identify how scientists used the scientific method to test this phenomenon.
Answer:
Scientists used the scientific method of investigation to test this phenomenon. The scientific method consists of these steps:
Make observations: Scientists observed that nerve damage causes severe pain. Scientists knew bone marrow cells seemed to decrease nerve pain, but the reason was unknown.
Ask questions and construct the hypothesis: Would injecting bone marrow cells into the spinal cord decrease pain?
Test the hypothesis: Injected bone marrow cells into the spinal cord of mice that had nerve damage. Observed changes in the cells, and monitored the pain levels in the mice.
Analyze the results and make a conclusion: Determined that the pain decreased because the bone marrow cells released a pain-relieving protein that helps damaged cells.
Test and modify: Make a plan to repeat the test in humans.

Master genes that affect development tend to be highly ____; therefore, similarities in patterns of embryonic development reflect shared ancestry that can be evolutionarily ancient.
Answer:
Master genes tend to be conserved.
Explanation:
Master genes, which are the genes in the DNA that control major development processes such as the development of the skeleton, the organs etc and the production of the necessary proteins.
Since they take on such an important role, they don't really change much. Master genes that affect development tend to be highly conserved so embryonic development can show similar patterns.

Which of the following processes is likely to occur in the leaves of a plant exposed to an atmospheric oxygen level of only 1% or 2%? a. hypoxia b. transpiration c. aerobic respiration d. anaerobic respiration
Answer:
A). Hypoxia.
Explanation:
Hypoxia is characterized as the condition in which tissues are deprived of an adequate supply of oxygen. As per this definition, hypoxia would be the process that is most likely to occur in the plant's leaves when it is revealed to a minimum level of 1 or 2% of oxygen. The lack of oxygen in such states reaches the tissues. One of the advanced stages of this process is 'anoxia; where there is a complete absence of 'oxygen' that enhances the ecological stress. Thus, option A is the correct answer.
Answer: aerobic respiration
Explanation: edg 2021
A form of exercise that involves short, intense bursts of energy; anaerobic exercise can only be maintained for 1–2 minutes, slightly longer through specific anaerobic training. Anaerobic exercises are generally used to build muscle mass, increase muscular strength, speed and power, for example sprinting (running, cycling, swimming, etc), and bodybuilding.
A. Anaerobic Exercise
B. Aerobic Exercise
Answer:
A). Anaerobic Exercise.
Explanation:
Anaerobic Exercise is characterized as the exercise that aims to break down glucose without making use of oxygen. Such exercise involves short, quick, and intense bursts of energy with maximum efforts. This leads to the body needing immediate energy(except oxygen) to fuel itself that eventually leads to the break down of glucose. This exercise primarily aims to 'build the mass of the muscles or enhance the muscular strength, through short and intense workouts involving jumping, sprinting, running, cycling, etc. Therefore, option A is the correct answer.

A recessive mutation causes short sightedness (ss) in cats. The frequency of homzygous wild type (+/+), heterozygous (+/s) and homzygous recessive (ss/ss) individuals was assessed in two populations of cats. The data is shown in the chart below. a. Are the two populations in Hardy-Weinberg equilibrium? Explain. b. If one population is not, what might cause this deviation?
Answer:
a. Only one of the two populations is in Hardy-Weinberg equilibrium
b. The Population of City cats is not in Hardy-Weinberg equilibrium because the proportion of dominant and recessive genes have been forced to change by outside force of migration, selection and mutation
Explanation:
By the Hardy-Weinberg Law, we have;
p² + 2·p·q + q² = 1
p + q = 1
p = Dominant allele frequency within the population
q = Recessive allele frequency within the population
p² = Percentage of individuals that are h o m o zygous dominant
q² = Percentage of individuals that are h o m o zygous recessive
2· p · q = Heterozygous individuals percentage
Therefore, for the country cats, we have;
p² = 0.49
p = √0.49 = 0.7
q² = 0.09
q = √0.09 = 0.3
2×p×q = 2×0.7×0.3 = 0.42 = The value given in the table
Which shows that the country cats are in Hardy-Weinberg equilibrium
For the city cats, we have;
p² = 0.52
p = √0.52 = √(13)/5
q² = 0.03
q = √0.03 = √3/10
2×p×q = 2×√(13)/5×√3/10 = √(39)/25 ≠ 0.45 which is the value given in the table
Which shows that the City cats is not in Hardy-Weinberg equilibrium
Therefore, only one of the two populations is in Hardy-Weinberg equilibrium
b. The Population of City cats is not in Hardy-Weinberg equilibrium because the proportion of dominant and recessive genes have been forced to change by outside force of migration, selection and mutation.
Following the Hardy-Weinberg theory, we can say that the country cats population is in equilibrium, while the City cats population is not. This is probably due to the action of evolutive forces.
Hardy-Weinberg equilibriumThe Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
p is the frequency of the dominant allele, q is the frequency of the recessive allele.The genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency), 2pq (Heter0zyg0us genotypic frequency), q² (H0m0zyg0us recessive genotypic frequency).If a population is in H-W equilibrium, it gets the same allelic and genotypic frequencies generation after generation.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
Solving the problemWe are given the genotypic frequencies of each population.
Now, we need to say if these populations are in H-W equilibrium, and if not, why?
So let us analyze each population separately.
Country CatsWe have the following genotypic frequencies, F(xx).
F(+/+) = p² = 0.49F(+/ss) = 2pq = 0.42F (ss/ss) = q² = 0.09Now, we need to get the allelic frequencies, p and q.
To do it, we will add half the heter0zyg0us frequency to each of the h0m0zyg0us frequencies.
p = 0.49 + (0.42/2) = 0.49 + 0.21 = 0.7p = 0.7 ⇒ Frequency of the dominant allele
q = 0.09 + (0.42/2) = 0.09 + 0.21 = 0.3q = 0.3 ⇒ Frequency of the recessive allele
Now, if this population is in H-W equilibrium, it will get the same allelic and genotypic frequencies generations after generation.
So now, we will get the genotypic frequencies (p², 2pq, and q²) of the following generation.
If p = 0.7 ⇒ p² = 0.7² = 0.49If q = 0.3 ⇒ q² = 0.3² = 0.092pq = 2 x 0.7 x 0.3 = 0.42The given genotypic frequencies in one generation are equal to the calculated genotypic frequencies in the next generation.
We can conclude this country's cats population is in Hardy-Weinberg equilibrium. No evolutive events are going on.
City Cats
We have the following genotypic frequencies, F(xx).
F(+/+) = p² = 0.52F(+/ss) = 2pq = 0.45F (ss/ss) = q² = 0.03Now, we need to get the allelic frequencies by adding half the heter0zyg0us frequency to each of the h0m0zyg0us frequencies.
p = 0.52 + (0.45/2) = 0.52 + 0.225 = 0.745p = 0.745 ⇒ Frequency of the dominant allele
q = 0.03 + (0.45/2) = 0.03 + 0.225 = 0.255q = 0.255 ⇒ Frequency of the recessive allele
Now, if this population is in H-W equilibrium, it will get the same allelic and genotypic frequencies generations after generation.
So now, we will get the genotypic frequencies (p², 2pq, and q²) of the following generation.
If p = 0.745 ⇒ p² = 0.745² = 0.555If q = 0.255 ⇒ q² = 0.255² = 0.0652pq = 2 x 0.745 x 0.255 = 0.379The given genotypic frequencies in one generation differ from the calculated genotypic frequencies in the next generation.
Generation 1 Generation 2
p² 0.52 0.555
2pq 0.45 0.379
q² 0.03 0.065
We can conclude that this city's cats population is not in Hardy-Weinberg equilibrium.
Probably some evolutive events are going on.
The evolutive forces affecting the H-W equilibrium are natural selection, genetic drift, and genetic flow. The mating system might also affect the equilibrium in this population.
