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.
Anyone know a research question.

b. Write a simple word equation to show how NPP is derived from GPP :
The net primary productivity (NPP) and the gross primary productivity (GPP) are related such that: NPP = GPP - Respiration
What is NPP?NPP refers to the net primary productivity of ecosystems. It is the amount of sugar made from photosynthesis when the amount of sugar burned during respiration has been deducted.
The total amount of sugar made during photosynthesis is the Gross Primary Productivity (GPP). This amount does not include the amount of sugar burned by respiration.
Thus, the equation relating the 3 variables would be:
NPP = GPP - Respiration

Mitochondria are membrane bound organelles that is found in the cytoplasm of cells of Eukaryotic organisms. They are responsible for generating energy in the cells , hence they are called the power house. They produce chemical energy in the cells in form of adenosine triphosphate (ATP) needed for cells activities and processes.

Explanation:
Why must cytosine bind to guanine, while thymine bonds to adenine?
a
These are Chargaff's rules.
b
Like bonds with like.
c
Two-ring molecules (adenine and guanine) must bind with one-ring molecules (thymine and guanine) to keep the distance between DNA chains consistent.
d
This will not happen, as it violates Chargaff's rules.
These are Chargaff's rules that is why cytosine bind to guanine, while thymine bonds to adenine. Thus, the correct option is A.
What is Chargaff's rule?According to the rule, in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine).
According to Chargaff's rule, Concentration of adenine = concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.

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.

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.

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.

2. What are three characteristics of carbon that contribute to the diversity of organic compounds?
Catenation:
The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.
Formation of multiple bonds:
Carbon atoms are capable of forming multiple bonds with other carbon atoms.
Hydrocarbons:
All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.
isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.
