Answer:

D.

Explanation:

The scientific method is a way of doing science that helps answer questions. It also helps to obtain new knowledge.

A way to answer scientific questions is the best description of the scientific process. Hence, option D is correct.

Through testing and experimentation, the scientific method establishes facts in an unbiased manner. Making an observation, formulating a hypothesis, making a prediction, carrying out an experiment, and then evaluating the findings are the fundamental steps.

The dissemination of the findings is the last phase in the scientific approach. After collecting and examining your data, you come to a conclusion regarding your hypothesis. A conclusion summarises the key takeaways from an experiment.

The best description of the scientific process is a way to answer scientific questions. Therefore, the correct option is D.

Explanation:

S. I. system is stands for the international system of unit of measurement, it is standardized internationally which is used in most of the nations around the globe so use of SI system be same between different scientists and stream of science.

It is helpful in communicating scientific data accurately so scientists and researchers can refer same quantity no matter region or location and language.

Thus, the correct answer is - option C.

Answer:

First of all is ventral: cavity that makes up the thoracic and abdominopelvic cavity ventral: cavity that makes up the thoracic and abdominopelvic cavity

Secondly it is thoracic: chest cavity

And thirdly it is pleural cavities: which consist of ths lung cavity

That is it will encounter tbe parietal layer of the serous membrane first :lines cavity

Explanation:

The organs in the body are safely guarded by the membrane, cavities and sheaths(which has different compartment). They act to protect the organs in the body like lungs.

A person who was shot with a gun, the bullet must pass the body cavities when moving to the lungs. It must first pass through the 3 cavities before it arrives at the lungs that is the ventral cavity, thoracic cavity and the pleural cavity. The serous membrane is usually found within the walls of the thoracic cavity.

Answer:

this represents response to the environment

Answer:

I determine if the object is a living thing by checking to see if it responds to the environment

Could determine if it is a living being by checking if it responds to stimuli

Living beings or organisms are all complex structures that are characterized by carrying out activities such as:

Some of the most common classifications of living organisms are:

According to the above, to know if that object is a living organism the best option would be to activate stimuli in it such as vision, touch, smell, hearing, or taste to see if it has any reaction to these stimuli.

For example, you can touch the object and if it moves it shows a response and therefore it is alive.

According to the above, the correct answer is checking if it responds to stimuli

Answer: The options are not given.

Here are the options.

collector should:

A) immediately withdraw the needle.

B) immediately remove the tourniquet.

C) lower the patient's head.

D) apply pressure for 5 minutes after withdrawing the needle

The correct answer is Option D.

The blood collector should apply pressure for 5 minutes after withdrawing the needle

Explanation:

Venipuncture is a process in medicine where needle is use to draw blood from veins for laboratory tests.

While performing a venipuncture, the blood collector notices bright red blood spurting into the tube, The blood collector should apply pressure for 5 minutes after withdrawing the needle so as to avoid complications in the patients , to ease pains and discomforts and it is done so that the veins will be positioned properly in its own position.

Answer:

convergent evolution

Explanation:

This is an example of the term known as convergent evolution. This term refers to the process in which organisms that are not related to one another are still able to independently evolve similar traits. This is all due to both of the species having to adapt to very similar environments thus needing to develop these certain traits in order to survive and pass them on to the next generation in that species line.

A round ball is an example of physical change. Thus option a is correct.

Physical changes are changes which affecting the form of chemical substances but not it's chemical composition. Physical change are the processes in which we can separate mixture from compound, but can't usually be used to separate compound into chemical elements or simplest compound.

Physical change takes place when mixture are can't separate by chemical changes then we separate by the help of physical change. In general a physical change is reversible using Physical means.

A physical change involves a change in physical properties. Example- physical properties including melting, freezing, sublimation etc.

Therefore, a round ball is an example of physical change. Thus, option a is correct.

Answer:

They cannot reproduce. People study biology only if they are planning to become biologists.

Explanation:

Explanation:

When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density

Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume.

Density is an important concept because it allows us to determine what substances will float and what substances will sink when placed in a liquid. Generally, substances float so long as their density is less than the density of the liquid they are placed in.

Density is a measure of how much mass there is in a given volume or amount of space. The density of any substance is calculated by dividing the mass of the matter by the volume of the matter.

Answer:Environmental servers build dams to keep water out of areas were animals safe.

Explanation:i just did this one and got it right!

Environmental science helped the trust decide that some dams should be removed dams reduces the complete ecological benefits that can be derived from the free-flowing rivers.

Dams may be defined as a type of barrier that is significantly constructed in order to hold back water and enhance its level that forms a reservoir that is utilized to generate electricity or as a water supply.

Environmental science believed that dams tend to synthesize numerous environmental impacts like alteration in wildlife patterns, destruction of wildlife habituation, interference with the natural flow of water, etc. Dams are also associated with the mechanism of ecological restoration and remarkably interfere with the natural characteristics of water and deteriorate it.

Therefore, environmental science fundamentally supports the trust decide that some dams should be removed.
