A scientist has a hunch that students learn best when they write down information with a pencil or pen. He organizes his students into two groups. Half of his students use pencil use pencil or pen to take notes in class every day and the other half type their notes on their laptops. At the end of the unit, all the students take the test and he looks at their scores to determine the outcome of the experiment. What is the dependent and independent variable? 100 points!!!!
Answer:
The correct answer would be :
independent variable : use of pen or pencil
Dependent variable : test scores (test of learning ability)
Explanation:
Independent variable of any scientific investigation or experiment is a variable that is manipulated or changed to see the change in dependent variable. In this case the variable that is changed or manipulated is use of pen or pencil to see that effect on learning ability.
Dependent variable is something that is measured or calculated to find the effect of the independent variable. In this case the dependent variable is test score that will provide idea that if hunch of scientist is true or not.
Thus, the correct answer would be :
independent variable : use of pen or pencil
Dependent variable : test scores (test of learning ability)

Explanation:
Which scenario would be most appropriate to study using a natural experiment? * the effects of an herbicide on human health the influence of sleep on exam performance the effects of an earthquake on blood pressure
Answer:
C. the effects of an earthquake on blood pressure
Explanation:
Natural experiments are observational studies in which participants are randomly assigned to groups that allow the researcher to draw causal relationships between an event and a factor. These experiments are used in studies where it would be unethical and unacceptable to subject human participants to such conditions. It is most times applied in epidemiological studies.
Since the researcher cannot control an earthquake which is a natural occurrence, this can be rightly described as a natural experiment. Controls are not used in this type of experiment.

Complete question: The chart shows the movement of a ball after several seconds.
Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?
a. Column A should be “Time,” and Column B should be “Position.”
b. Column A should be “Position,” and Column B should be “Time.”
c. Column A should be “Velocity,” and Column B should be “Speed.”
d. Column A should be “Speed,” and Column B should be “Velocity.”
Answer:
Column A should be "Time," and Column B should be "Position"
Explanation:
In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.
Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".
Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.
Option C) and D) are not possible, as both of them are variables that depend on time.

How do bacterial species build antibiotic resistance? Do viruses do the same thing?
Answer:
When bacteria develop fortifications against the antibiotics that are developed to eradicate them it is termed as antibiotic resistance. Antimicrobial resistance is not only applicable to bacteria, but it is also applicable to other germs like fungi or viruses. There are various ways by which bacteria develop confrontation against antibiotics.
Some bacteria are naturally resilient due to the nonexistence of the target that the antibiotic attacks or due to a remarkably impervious cell membrane. Some of the bacteria possess the tendency to generate enzymes, which can incapacitate antibiotics at the time of acquaintance. In some of the situations, bacteria can change the target of the antibiotics, making the antibiotic inefficient. The generation of efflux pumps in some of the bacteria makes antibiotics to get transport out of the bacterial cell.
The antibiotics are not efficient against viral infections like influenza, colds, bronchitis, the majority of sore throats, and many ear infections and sinuses. The widespread application of antibiotics for these illnesses can generate the spread of antibiotic resistance.

A cell is round and cannot produce its own food. Which organelle does this cell have?
A. cell wall
B. central vacuole
C. chloroplast
D. plasma membrane
I decided that B and C were incorrect since they contribute to helping with making food. My final answer was plasma. Would that be correct?
Answer:as I think a plant cell can produce there own food so we should separate organelles which are found in the plant with that of the animal so cell wall , chloroplast and plasma membrane are characterstics of plant finaly the answer should be centeral vacoule which is the animal organelle
The cell, which is round and cannot produce its own food, has a plasma membrane.
TYPES OF CELL:
There are two major types of cell in biology namely: plant cell and animal cell. These two cells have characteristics they share in common and also that they have differently. According to this question, a cell that is round and cannot produce its own food is an ANIMAL CELL because animals are heterotrophic i.e. cannot synthesize their own food.An animal cell lacks the following organelles:

Manifestations of osteoarthritis include ( Select all that apply.) nodules on joints of the hands. crepitus with joint movement. pain that is worse upon arising in the morning. stiffness that worsens with joint use. narrowing of joint spaces
Answer:
All options are correct, that is, they would all be correct for osteoarthritis.
This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.
Explanation:
Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.
The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).
This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".

In the early days of germ theory, contagious diseases were thought to be caused only by fungi or bacteria. In the 1890s, Dmitri Ivanovski filtered extracts from diseased tobacco plants and discovered that the disease could be transmitted to new plants through the filtrate. He hypothesized that something smaller than bacteria or fungi was responsible for the transmission of the disease. Which best explains how Ivanovski's work led to a change in the germ theory? He tried to promote his hypothesis as a law. He used a new experimental method to test his hypothesis. He used a more powerful bacterial strain than other scientists had. He obtained results that confirmed what other scientists were thinking.
Answer:
He used a new experimental method to test his hypothesis.
Explanation:
Dmitri Ivanovski, a Russian microbiologist who was born in the year 1864 and died in 1920. He was the scientist who initiated the discovery of viruses as a pathogenic microorganism. He worked to discover the cause of mosaic disease in tobacco plant and he hypothesized that that something smaller than bacteria or fungi, as early believed, was responsible for the transmission of the disease.
In order to test his hypothesis, he passed a solution containing the causative agent of the disease, which he prepared from the infected plant leaves, through a filter known as Chamberland filter. He was able to discover that the filtrate still contained microbial pathogens that can infect more tobacco plants, confirming his hypothesis that something smaller than fungi or bacteria is responsible for the tobacco mosaic infection.
Hence, to test out his hypothesis, Ivanovski in the 1890's used a new experimental method i.e. CHAMBERLAND FILTER method.

. "Horses can swim
faster than dogs" What is the independent variable?
Answer:
See the answer below
Explanation:
The independent variable would be the type of animal (horse or dog).
In the course of an experiment, the independent variable is the variable whose value does not dependent on the value of any other variable in the experiment. It is the variable that the researcher can control during the course of an experiment and whose manipulation changes or influences the actual variable the researcher is set out to measure.
I this case, if an experiment is set up to test the hypothesis that horses can swim faster than dogs, the actual variable that the experimenter would set out to measure would be the speed at which the two animals can swim. As the animals are interchanged for each other, the speed of swimming would vary.
Hence, the type of animal is the independent variable while the speed at which swimming takes place would be the dependent variable.
