H2O is acquired by osmosis in the plants cells, and or through the stomata. CO2 is obtained in the way of the Stomata.

CO2 is carbondioxide that comes from what humans exhale, and H2O is water that comes from the water cycle either through precipitation or under ground.

A biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. What type of data will

iragen [17]

Answer:

$\boxed {\boxed {\sf They \ will \ gather \ quantitative \ data \ using \ a \ thermometer \ and \ a \ balance}}$

Explanation:

First, let's identify the tools needed.

Since the biology class is studying the temperature, they will likely need a thermometer. Also, they are gathering information about the growth of the plants. This could use a balance of a meterstick.

Next, recall the difference between quantitative and qualitative data.

Quantitative: Measurable and numerical results found using scientific instruments/devices
Qualitative: Data found using the senses, such as descriptions and diagrams.

Since the class is measuring temperature and growth using tools, it must be quantitative data.

We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.

For biological evolution to occur by way of natural selection, the trait being selected for need NOT:

grandymaker [24]

The answer is c. Natural selection is when inheritable traits that they need to survive is passed down to the next generation. Biological revolution changes the environment so the organism's offspring has to change with it through genetic variations. If you increase it's life span than you may not have genetic variation over a period of time.
