(06.05 MC)

Two students are comparing scientific experiments to investigations. They came up with the following ideas.

Student A: Testing plant growth in different types of soils
Student B: Comparing the water level in a lake during different times of the year

Which student gave an example of a scientific experiment? (5 points)
Student A because it requires experimental and control groups
Student B because it requires a hypothesis
Student A because it is preferably done in natural settings
Student B because it is preferably done across a long period of time

Brainliest for correct answer :)

Use the diagram below to help you answer the following questions.

*Note that in the images below changes in eccentricity are exaggerated so the effect can be seen in the images. Earth's orbit shape varies between 0.0034 (almost a perfect circle) to 0.058 (slightly elliptical).*

a. A change in the eccentricity of Earth's orbit towards its maximum will increase or decrease the solar input that the Earth receives?

b. Explain how an increase in the eccentricity of the Earth’s orbit will alter the climate.

SC.8.P.8.2 7-As an astronaut travels from the surface of Earth to a position that is tentimes as far away from the center of Earth. Based on the Law of Gravity ,which of the following statement is true?
A. Mass decreases and the gravitational pull from Earth increases. B. Weight increases and the gravitational pull from Earth stays the same. C. Mass remains the same and the gravitational pull from Earth decreases. D.Weight remains the same and the gravitational pull from Earth increases.

A group of scientists wants to observe the adaptation of a foreign fish species in a river ecosystem. To do this, they want to enclose the top and sides of a section of a river to block light and matter from entering the area. Evaluate whether this experimental system is an isolated system. Justify your answer based on the definition of an isolated system.

A) Are always higher
B) Have wide ranges
C) Have narrow ranges

2. Ocean water, in equatorial regions, stores large amounts of solar energy because of the direct sunlight it receives. Solar energy can be distributed to higher latitudes by __________

A) Deep ocean currents
B) Surface currents
C) Ocean waves

3. The distribution of solar energy by warm ocean currents causes regions at higher latitudes, such as the United Kingdom, to have a __________ climate, compared to other locations at the same latitude.

A) More moderate
B) More extreme
C) Colder

Two great snowbirds are migrating. Both birds have a mass of 100 g under flag it 90 km/h. Birds are is flying 2.0 KM above the ground, and very cute is fine 2.5 KM above the ground. Based on the information above, which statement best describes the energy of the two birds?

How are skills learned in older generations passes down to younger generations?

Below is a drawing of a fossil that is millions of years old. This fossil was just taken out of the ground, and no one knows what kind of organism it is. One way scientists identify a fossil of an animal with bones is to compare the bones of the fossil to the bones of other animals.


Do any of these fossil’s bones look like bones of other animals? Describe your thinking.

Polly is explaining the Law of Conservation of Energy to her friend. She is using a light bulb as an example. Which of the following statements best explains this law?
A.
"Electrical energy is destroyed to create light and thermal energy."

B.
"Potential energy is used to create electrical energy and release light and thermal energy."

C.
"Electrical energy is transformed into light and thermal energy and released to the surroundings."

D.
"Electrical energy created by the light bulb is converted into light and thermal energy and used up by the surroundings."

What is species extinction and what are the primary causes?

The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. ... The best way is to use a hand crank such as a hand cranked flashlight or radio because it is easy to power enough energy for a short amount of time.
