A doctor counts the number of asthma attacks a person has after switching medications. Which type of data is she collecting? Quantitative data qualitative data experimental data observational data
Answer:
Quantitative data
Explanation:
The collection of data is very key to any experiment as it is the way in which the results of what is being tested is analysed. There are however, two ways to scientists collect data in their investigation. These ways are quantitatively and qualitatively.
Quantitative data collection involves the type that has to do with numbers or counts while qualitative data does not deal with numbers. In this question, a doctor counts the number of asthma attacks a person has after switching medications. The COUNTING represents that the type of data collected by the doctor is QUANTITATIVE.
Answer: Quantitative Data

Answer:
Constructing a safe passage for fish seems like a way to avoid the problem, and in theory, it could reduce the risk of injury or death to fish. But my research shows that building fish passages can be difficult, and their effectiveness is mixed. Also, different passages may need to be built for different species, which is time-consuming and costly.
Working with engineers to design a dam with these risks in mind seems to be the ideal solution, because we can design the dam with the native species in mind. But the biodiversity issues related to hydroelectric dams is a fairly new concern, so we may not have a lot of past evidence to reference. We may have to use the trial and error method, which seems risky.

Describe the role of steam in a nuclear power plant
The role of steam in a nuclear power plant is to generate electricity.
In nuclear power plant, the heat energy that is produced from nuclear fission is used to boil water that is present in huge boilers. Due to high amount of heat energy, the water turns from liquid to steam or gaseous state. This steam is collected in a chamber and release it with a huge pressure on the blades of the turbine which start moving due to this steam and as a result electricity is produced so we can conclude that steam is used to produced electricity in the nuclear power plant.

is water more acidic than air
Answer:
Yes, water is more acidic than air
Explanation:
carbon dioxide in the air can dissolve into bodies of water. The extra carbon dioxide in soda water imparts more acidity to the liquid than would be in gases.

Louis Pasteur likely worked with a hypothesis similar to this one:
"If liquids are heated to a certain temperature and germs die, then the liquids will be less likely to cause sickness when consumed, because reducing germs is a way to prevent disease.”
How was this new hypothesis most likely inspired by the work of Joseph Lister?
Lister had taught that boiling water makes it safer to drink.
Lister’s experiments showed that reducing germs during surgery prevented infection.
Lister’s experiments showed that germs can cause infection no matter how they enter the body.
Lister had established the fact that germs grow and spread through air and foods.

A student pushes a television cart to the left with a constant force of 100 N. The force of friction between the cart and the floor pushes back to the right with a force of 75 N. If the cart was initially at rest, how will it move as the constant force is applied?
Answer:
Explanation:
As you can see in the badly drawn picture below, the force pushing to the left is 100N while the opposing force pushing the right is 75N. These forces are subtracted from one another, which would leave us with a total force of 25N (100N - 75N = 25N) pushing to the left. Since the cart is initially at rest, this means that there is no additional force being applied left or right of the cart. Therefore, with the 25N of force, the cart would move at a constant speed to the left.
If the cart is at rest, it will move to the left at a constant speed.
We can arrive at this answer because:
The cart is at rest when no force is applied to it.When the student pushes the cart to the left with a force of 100N, the cart will be forced out of rest if this force is greater than the drag force, which pushes the cart in the opposite direction.As we can see, the force that pushes the cart in the opposite direction is equal to 75N, and therefore, we can say that the cart will move to the left.However, the movement of the cart will not be done with a force of 100N, as 75N of this force will be canceled out, due to the force that pushes the cart in the opposite direction. In this case, the cart will move with a force of 25N.

Answer:
B
Explanation:
Movement is not a function of hair, as having less of it actually technically makes it easier to move.
A- true, eyelashes and other hair protect from harmful sun and irritants
C- hair is generally considered to be a sensory organ
D- hair is most commonly considered a way for animals to stay warm
The function that is not of the hair is movement. The correct option is b.
What is hair made of?Keratin, a tough protein, is used to make hair. Each hair is anchored into the skin by a hair follicle.
The hair bulb is basically the foundation of the hair follicle. Living cells divide and grow in the hair bulb to form the hair shaft.
Keratin is produced by keratinocytes and is insoluble in water, ensuring the hair's impermeability and protection.
Hair DNA is genetic material that is used to build our hair. Person's hair follicle encompass nucleic acid DNA, while our hair shaft contains mitochondrial DNA."
Hair functions include protection, temperature regulation, and perspiration evaporation; hairs also function as sense organs.

A. organelles
B. genes
C. organs
D. cells
Tissues are not present in the Phylum Porifera, then there is are no organs. So, the correct option is C.
What is Phylum Porifera?The members of the phylum Porifera are called sponges which are generally marine and mostly asymmetric animals. These are primitive multicellular animals and have a cellular level organization that lacks tissues.
These organisms belong to the phylum Porifera, which lack most of the structures present in multicellular organisms such as the digestive system, respiratory system, brain, etc.
The body of sponges which is made up of spicules or spongin fibers and these organisms have a water canal system which helps them in digestion, reproduction and capture of their food in marine habitat.
Thus, tissues are not present in the Phylum Porifera, then there is are no organs. So, the correct option is C.

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
a scientific theory? Do you think it should be a scientific law? Explain your response.
Yes, Because that theory can easily be backed up with facts and evidence making it a scientific law
Answer:
Cell theory meets the definition of a theory because it has been tested over a long period of time, and scientists have plenty of evidence to support this theory. However, it doesn’t seem to meet the criterion of a scientific law. Scientists only know about life on this planet, so the theory may not be universal if life is found on other planets. In addition, scientists don’t have much data on the earliest forms of life on Earth.
