Predict the initial consequence to the lake due to a sudden influx of nutrients in the form of fertilizers due to run off from nearby farm fields
Answer: The initial consequence to the lake due to a sudden influx of nutrients in the form of fertilizers due to run off from nearby farm fields is the rapid growth of algae. The influx of nutrients lets algae thrive and can cause eutrophication, which will eventually lower dissolved oxygen levels.

4. Define free energy, and explain how its change is calculated.
We can calculate the change in free energy for a reaction under nonstandard conditions by using the ΔG = ΔH - TΔS equation.
How do we calculate chnage in free energy?Change in gibbs free energy of any reaction will be calculated by uisng the below equation as:
ΔG = ΔH - TΔS, where
ΔH = change in enthalpy
T = temperature of reaction
ΔS = chnage in entropy
By putting all given values we can calculate the gibbs free energy of the reaction, and negative sign of energy shows the spontaneity of the reaction.
Hence by using the enthalpy, entropy and temperature we can calculate the free energy change.

Free energy refers to the energy in a system that is free to do work i.e. the internal energy minus any energy that is unavailable to perform work.
Why is use of free energy?Free energy is used to determine how systems change and how much work they can produce. It is expressed in two forms: the Helmholtz free energy F, sometimes called the work function, and the Gibbs free energy G.
The free energy change of a reaction can be calculated using the following expression: ΔG∘=ΔH∘−TΔS∘. where ΔG=free energy change.

how does the material and color of the jacket affect heat absorption?
If a plant looks purple, which light color is causing the plant to photosynthesize?
Green
O Purple
O Blue
Red
Answer:
Purple
Explanation:
To perform photosynthesis, violet light is the most important color, and it's from these wavelengths that plants get most of their energy. The reason for this is because out of the visible spectrum, red light is the longest wavelength light that the photosynthesis process can use, but it has the least energy
6. Photosynthesis can combat global warming. Explain with reasons.
Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet.
Explanation:
Plants, through photosynthesis, and soils sequester roughly a third of carbon dioxide emissions released into the atmosphere each decade from the burning of fossil fuels. During photosynthesis, plants open tiny pores on their leaf surfaces to suck carbon dioxide from the air and produce their own food.
Consider the following food chain: Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes. What will happen to the other members of the food chain if the grasshoppers are removed
Answer:
If the grasshopper is removed, the snakes will die, because the snakes have nothing to eat, and whatever eats snakes will die, and so on.

Im studying human scalp does anyone know what this is?
The picture represents the atypical mole or also known as dysplastic nevi. Such types of moles are looking unusual and have irregular features under the microscope.
What is a Human scalp?A human scalp may be defined as the fraction of the envelope of the human head usually covered with hair in both sexes. It is the region that is composed of soft tissue layers that cover the cranium.
The dysplastic nevi are although benign in nature but significantly have a potent threat to melanoma which is a dangerous form of skin cancer.
Such types of moles are painful, itching, crusting, and swelling with the duration of time. They are required to be checked immediately by a trusted dermatologist.
Therefore, the picture represents the atypical mole or also known as dysplastic nevi.

What is the independent variable in an experiment testing if caffeine affects the way common house spiders build webs?
a.the number of house spiders you give caffeine to
b. the amount of food you feed the house spiders
c. the body mass of each house spider
d. the amount of caffeine the house spiders receive
Answer:
d.
Explanation:
The independent variable in an experiment is the variable that is manipulated to test a hypothesis. In this case, that is caffeine. In order to study the effects, they have to give different amounts to spiders
The independent variable in an experiment testing if caffeine affects the way common house spiders build webs is the amount of caffeine the house spiders receive. The correct option is b.
What is variable?In science and research, a variable is any factor or condition that can be measured, controlled, or manipulated.
The independent variable is the variable that the researcher manipulates or changes in order to observe its effect on the dependent variable.
In this case, the researcher is interested in the effect of caffeine on the way house spiders build webs, so the amount of caffeine that the spiders receive is the independent variable.
The other options, such as the number of house spiders, the amount of food, or the body mass of the spiders, are not being intentionally manipulated in this experiment and therefore are not the independent variable.
Thus, the correct option is b.

How can a medical transcriptionist make sure that the information he or she found on the Internet is valid and accurate? Explain.
Answer:
What is Medical Transcription?
Medical transcription is when a medical report is typed from a dictated audio file recorded by a physician, a nurse, or some other healthcare provider.
Doctors, nurse practitioners, surgeons, and other healthcare providers have important, stressful jobs. They’re on their feet all day, doing everything they can to help the patients in their care. There’s a lot that can get in their way, however, and many frequently express frustration in getting so bogged down with paperwork that it limits their time with their patients.
The number one task that can suck up too much time from healthcare providers is transcribing their own notes. These notes can include everything from clinical summaries to surgery notes. Taking an audio recording and turning it into a written document that’s needed for their own records, insurance claims, and patient’s medical charts can take some providers a few hours per day.
