Where should the biosphere label appear in this systems
model?
Answer:hydresphyr
Explanation:
How might you model the relationship between a tomato plant and the hornworm caterpillar?
Answer:
This model can be called a parasitic relationship
Explanation:
A parasitic relationship is a form of relationship/interaction between two organisms in which one organism (called parasite) lives at the expense of the other organism (called host); causing harm or death to the host.
A hornworm caterpillar feeds on the upper part of tomato plant leaves, causing harm to the plant in the process. Hence, the tomato plant is the host while the hornworm caterpillar is the parasite.
You want to determine if a new diet medication will help rats to lose weight. What is the dependent variable? * the rats weight loss diet medication the food
Answer:
the rats weight loss
Explanation:
The dependent variable would the weight of the rats.
The dependent variable is the variable whose value is dependent on another variable during an experiment. It is the actual variable set out to be measured or tested by researchers. The effect of the manipulation of the independent variable is measured on the dependent variable.
Hence, in an experiment aimed at determining whether a new diet medication will help rats to lose weight, the weight loss by the rats would be the dependent variable.

A scientist is testing how caffeine affects people’s sleep. She asks one group of people to drink one can of Coke before bed. She asks a second group of people to drink one cup of water before bed. Over a period of one month, she determines that the Coca Cola drinkers slept 45 minutes less per night than the water drinkers. What is the INDEPENDENT VARIABLE?
Answer:
The type of drink with different caffeine contents.
Explanation:
When conducting an experiment, two variables are looked out for, they are: independent variable and dependent variable. Independent variable refers to the variable being controlled or altered in the experiment in order to induce an effect in the dependent variable, which is the variable being measured. The outcome of the dependent variable is dependent on the input or independent variable.
In this question, the scientist is testing how caffeine affects people's sleep. She uses different drinks i.e. Coca-Cola and water with different caffeine contents to test out it's effect on the time of sleep people in the different groups will have. Therefore, the type of drink is the INDEPENDENT variable because it is being changed to test an effect on the dependent variable. The amount of time of sleep is what is being measured, hence it is the dependent variable.
Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that shows the amino acid sequence differences between different organisms for a protein keratin. Changes in amino acid sequences are known to cause changes in structure of proteins. Species A Species B Species C Species D Species E Species A 4 11 19 1 Species B 12 18 5 Species C 8 10 Species D 20 Species E Part A. Consider species A, D, and E. Using the data provided, describe how the structures of their keratin proteins would compare. Part B. Keratin is made up of about 450 amino acids. Determine the similarity in percentages between species A and B, A and C, and B and C. Explain how amino acid sequences can be used in determining how closely related two species are. Part C. Based on this data, predict which two species would be more closely related to one another. Part D. Justify your predictions to part C.
Answer:
A) Species A and E are more closely related than either species are related to species D.
B) Between A and B = 99.1%
Between species A and C =97.5%
Between species B and C = 97.3%
Similarity in amino acids sequence reflects similarity in DNA sequence
C) Species A and E are most closely related
D) Species A and E have the most similarity in amino acid sequence, and hence DNA sequence.
Explanation:
A) The amino acid sequences of the protein, keratin, in species A and D has a difference of about 19 whereas species A and E have a difference of only 1. Therefore, it means that keratin in species A and D will have differences in structure whereas between species A and E, they would have almost the same structure.
Also, species D and E have a difference of 20 in their amino acids sequence, therefore, the structure of keratin in both species will have differences in structure.
B) Similarity between A and B:
450 - 4 = 446
In percentage: 446/450 × 100% = 99.1%
Similarity between A and C:
450 - 11 = 439
In percentage: 439/450 × 100% = 97.5%
Similarity between B and C:
450 -12 = 438
In percentage: 438/450 × 100% = 97.3%
The sequence of DNA of species determines their amino acid sequences because information in DNA is transcribed to RNA which are then used to make proteins. Therefore, if a species are very closely related, they are expected to have very similar genetic sequences and thus proteins too. This is reflected in similarity between amino acid sequences in their proteins.
C). Species A and E are most closely related.
D) Species A and E have only a single difference in their amino acids sequence for Keratin. This translates to about 99.7% similarity which is the highest among all the species compared. Therefore, species A and E are most closely related.

Which applied force will cause a glass of water sitting on a countertop to move?
A. a balanced force
B. a frictional force
C. a gravitational force
D. An unbalanced force
Answer:
The correct answer is D. an unbalanced force.
Explanation:
If an unbalanced force were applied to the glass of water (for example, someone pushing the glass, lifting it up, etc.), this would cause it to move. However, a balanced force (if two people were to simultaneously pull the glass in opposite directions with the same amount of force) would not cause the glass to move. Gravitational force acts on all objects; the force due to gravity is already acting on the cup at rest and will not cause it to undergo motion. Friction is also already acting on the cup in the form of static friction, making it harder for someone to move the cup, so frictional force will not cause the cup to move either. Therefore, the correct answer is D. an unbalanced force.

Answer:
The SI unit for measuring weight is newtons
Explanation: The unit of measurement for weight is that of force, which in the International System of Units (SI) is the Newton. For example, an object witha mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
What are the differences among the five biogeochemical cycle,particularly on the roles organisms play in them?
Answer:The most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, phosphorus cycle, and the water cycle. The biogeochemical cycles always have a state of equilibrium
Explanation:
Contrary to energy flow, matter, the building block of which organisms are made, flows through an ecosystem in several cycles, from one organism to the next and from living things to the abiotic environment and back.
What are biogeochemical cycles?
The flow of nutrients and other elements between biotic and abiotic forces is referred to as "biogeochemical cycles." The words "bio" and "geo," which refer to the biosphere, "geo" and "chemical," which refer to the elements that flow through a cycle, are the roots of the phrase "biogeochemical."
Atoms make up the preserved stuff that exists on Earth. Since matter cannot be generated or destroyed, it is recycled in a variety of ways throughout the earth's system. The remainder of the elements are present in a closed system, and the earth receives energy from the sun that is reflected back as heat. Major components include:
CarbonHydrogenNitrogenOxygenPhosphorusSulfurThe biotic and abiotic parts of the ecosystem recycle these substances. The abiotic elements of the ecosystem are the lithosphere, hydrosphere, and atmosphere.
Therefore, contrary to energy flow, matter—the building block of all living things—moves through an ecosystem in a variety of cycles, from one creature to the next and from the abiotic environment to the living ones and back again.

In an effort to control vegetation overgrowth, 108 rabbits are released in an isolated area free of predators. After 2 years, it is estimated that the rabbit population has increased to 972. Assuming exponential population growth, what will the population be after another 9 months
Answer:
246
Explanation:
Increased amount / current population = 972
Amount released = 108
time(t) = 2years
Using the exponential growth function :
f(t) = A*g^t
Where g = growth rate
To obtain the growth rate = g
972 = 108 * g^2
g^2 = 972 / 108
g^2 = 9
g = 3
To determine population after 9 months :
9 months to years = (9/12) = 0.75
t = 0.75
f(0.75) = 108*(3^0.75)
f(0.75) = 108 * 2.2795070
f(0.75) = 246.18676
= 246

state the difference between osmosis and active transport
Answer:
Osmosis is movement of water molecules from an area of their higher concentration to area of their lower concentration through a semipermeable membrane.
Active transport is movement of molecules from an area of their lower concentration to area of their higher concentration using energy in form of ATP by pump proteins.
Explanation:
transport system is consider as the opposite to osmosis. Because you are going against the gradient, active transport requires a pump or carrier protein in the cell membrane and therefore energy (made through respiration).
A biology student wanted to determine if there is a relationship between resting heart rate and time spent exercising per week.
Answer:
YES, there is a relationship between resting heart rate and physical activity.
The higher the physical activity, the better the physical performance, the better the cardiac contractile quality, therefore the lower the heart rate at rest.
Explanation:
The heart is a muscle that is trained like the rest, when practicing physical activity it contracts and expels blood more often and more intensely.
Thus generating that the contractile power is more effective, that is to say that in each bombardment it ejects more blood into the aorta, therefore there will be less effort at rest.
This is how training generates hypertrophy of myocytes, they contract better, generate blood ejection to the vascular system in a more efficient contraction compared to sedentary, therefore the oxygenated volume will not have to be replaced immediately, thus generating the heart have to beat or eject more slowly.
By contracting fewer times per minute, we are faced with the phenomenon of decreased heart rate, this is measurable by taking the pulse of an athlete at rest and comparing it with a sedentary person also at rest.
Answer:
69 bpm
Explanation:
1.) There is an inverse trend seen in the graph. Students who do less exercise tend to have a higher resting heart rate, while students who do more exercise tend to have a lower resting heart rate.
2.) Using the line created by the data points, we can determine that students who exercise around 3 hours per week seem to have resting heart rates between 68-72 bpm.
3.) The correct answer is: 69 bpm
