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

Explanation:

Answer:

Oxygen

Explanation:

Oxygen is a gaseous non-metal element that is taken up by animals (heterotrophs) during the process of respiration. Animals need oxygen to be able to survive.

Oxygen is produced by plants (autotrophs) into the atmosphere through a process called photosynthesis. The process of photosynthesis is when plants take up carbondioxide and water in the presence of energy captured from sunlight and further produces glucose (carbohydrate) and release oxygen into the atmosphere as a byproduct.

Answer:

The correct answer is True.

Explanation:

An ion is formed when an atom looses or gain electron. If an atom gains electrons, it will have more number of electrons than protons. Thus, it will carry negative charge and will lead to the formation of anion. If an atom looses electrons, it will have less number of electrons than protons.

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.

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.

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.

Answer:

The girl hears the ambulance sound different. The first part of the picture shows the girl and the sound waves, and they are right in front of her, so she cannot hear them as well. But the second image shows the girl in the middle of the sound waves. This is the strongest and loudest part of the sound waves, so it sounds different to the girl in the image.

Also, in the first image, the sound waves would most likely sound higher than in the second image. The sound would continue to get lower in frequency the father it drove away. This is because of the Doppler Effect. The Doppler Effect refers to the change in wave frequency during the relative motion between a wave source and its observer.

Keystone species, in ecology, a species that has a disproportionately large effect on the communities in which it occurs. Such species help to maintain local biodiversity within a community either by controlling populations of other species that would otherwise dominate the community or by providing critical resources for a wide range of species. The name keystone species, coined by American zoologist Robert T. Paine in 1969, was derived from the practice of using a wedge-shaped stone to support the top of an arch in a bridge or other construction. Just as other stones in the construction depend on the keystone for support, other species in a biological community depend on the presence of a keystone species to maintain the community’s structure.

The starfish Piaster ochraceus is a keystone species in the rocky marine inter tidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mustily Californians and is responsible for maintaining much of the local diversity of species within certain communities. When the starfish have been removed experimentally, the mussel populations have expanded rapidly and covered the rocky inter-tidal shores so exclusively that other species cannot establish themselves. Consequently, the interaction between Piasters and Mustily supports the structure and species diversity of these communities. In other communities in which Piasters occurs, however, the starfish has little overall effect on the structure of the community. Therefore, a species can be a keystone species in some communities but not in others.

b. garbage releases toxins that can cause land and air pollution

Explanation:

Non biodegradable materials are those materials like plastic, nylon, runner etc. that cannot be broken down by microbial action, hence, cannot be decomposed. These materials constitutes waste materials in our environment and cause pollution, which is the release of toxic or harmful substances into our immediate environment.

Recycling or reusing of these non-biodegradable waste is one of the ways to lessen the garbage in the environment. Once the garbage are lessened, the level of pollution is automatically being minimized. This is because garbage releases toxins that can cause land and air pollution.

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:

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.

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.

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.
