A sound has a higher pitch than a bell. Which quantity must also be higher in this sound than in the bell?(1 point)
Responses
amplitude
speed
wavelength
The quantity that must also be higher in a sound that has a higher pitch than a bell is the frequency.
Which statement about the effect of temperature on the speed of sound is correct?(1 point)
Responses
As temperature increases, the speed of sound increases because the medium becomes denser.
As temperature increases, the speed of sound increases because the medium becomes denser.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
Changes in temperature have no effect on the speed of sound.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.

A student is using a weak computer to design a logo. If the weak computer is the only constraint, should the student use the online version or downloaded version of a graphic design software?(1 point)
Responses
The online version, because the downloaded version usually requires better equipment than the online version.
The online version, because the downloaded version usually requires better equipment than the online version.
The online version, because the downloaded version may have limited bandwidth that limits how quickly the designer can work.

What is the energy released during cellular respiration used for?(1 point)
Responses
photosynthesis
photosynthesis
to create more glucose
to create more glucose
cellular functions
cellular functions
it is released to the environment
The energy released during cellular respiration is used for cellular functions, such as synthesizing ATP and powering cellular processes.
so which is the correct option
The correct option is "cellular functions".
In this ecosystem, oak trees have a biomass of 124,778 gm2
and create 78,871 kcalm2yr
of energy.
How much energy will the secondary consumer have?

12,477.8 gm2
78.871 kcalm2yr
78.871 kcalm2yr
It's not possible to determine the amount of energy the secondary consumer will have with only this information about the oak trees. The question would need to provide more details about the trophic levels and energy transfer within the ecosystem.
which number would make more sence it has to be one of the following
Unfortunately, since the information provided is not sufficient to calculate the energy of the secondary consumer, none of the given options make sense.
Imagine a large tree in a rainforest. Which of the following is true about it?(1 point)
Responses
If the species of this tree becomes overpopulated, primary consumers will suffer.
If the species of this tree becomes overpopulated, primary consumers will suffer.
Primary consumers of this tree will need to consume many trees over their life times.
Primary consumers of this tree will need to consume many trees over their life times.
Many primary consumers can just consume that one tree for their entire lifetimes.
Many primary consumers can just consume that one tree for their entire lifetimes.
Primary consumers of this tree will need to consume many trees over their life times unless they have short lifespans
Many primary consumers can just consume that one tree for their entire lifetimes.
What is true about adaptation and speciation?(1 point)
Responses
Speciation consistently leads to adaptations.
Speciation consistently leads to adaptations.
Adaptations consistently lead to speciation.
Adaptations consistently lead to speciation.
Adaptation occurs frequently, while speciation occurs unusually.
Adaptation occurs frequently, while speciation occurs unusually.
Adaptations and speciation are both rarely observed.
Adaptations can lead to speciation, but speciation does not consistently lead to adaptations.
so which is da answer
The answer is "Adaptations can lead to speciation, but speciation does not consistently lead to adaptations."
Simultaneous coevolution on Earth is a result of changes in one system affecting another. Identify one cause and a feedback response.(1 point)
Responses
Increased ozone protection from UV radiation allowed animal evolution.
Increased ozone protection from UV radiation allowed animal evolution.
Soils developed and allowed bacteria and microbes to grow.
Soils developed and allowed bacteria and microbes to grow.
Water condensed on the ground and cooled the Earth.
Water condensed on the ground and cooled the Earth.
Red iron oxide lines in rocks caused greater oxygen production.
Increased ozone protection from UV radiation allowed animal evolution is the cause, while the feedback response is the evolution of animals to further adapt to and utilize this increased protection from UV radiation.
ver millions of years, at a convergent boundary, rocks are pushed up against each other, creating a small set of hills. The hills are right on the ocean’s shoreline. The ocean water constantly beats on the rocks, taking small pieces of the rock back with it each time. The strong ocean winds also take away pieces of the rock constantly, carrying them into the ocean or other nearby areas. This causes the rock structure to have a unique, jagged, and beautiful shape.
