Answer:

I think C. Petri dishes

Explanation:

"The most common growth media nutrient broths (liquid nutrient medium) or LB medium (Lysogeny Broth) are liquid. These are often mixed with agar and poured into Petri dishes to solidify. These agar plates provide a solid medium on which microbes may be cultured."-https://courses.lumenlearning.com/boundless-microbiology/chapter/culturing-bacteria/

I hope this helps!

Answer and Explanation:

The people within this age range most likely want a baby for themselves/want more babies, or they don't feel like they should have to be limited to the amount of babies they want.

Which abiotic factor most likely controls where the plants live in this environment
Setler [38]

Which abiotic factor most likely controls where the plants live in this environment ?

Oxygen levels for aquatic animals

Oxygen from the air and oxygen produced by aquatic plants dissolves in water. Without this, aquatic animals would suffocate and die. Healthy lakes and rivers have high levels of oxygen, and polluted waters often have low levels of oxygen. This pollution means that only certain species can survive there such as sludgeworms. These are bioindicator species because their presence or absence informs us about the condition of the habitat.

Carbon dioxide levels for plants

Carbon dioxide is a reactant in photosynthesis which means plants need it to survive. Areas with higher levels of carbon dioxide are more likely to have healthy plants growing. Farmers often release carbon dioxide within their greenhouses to maximise their crop yield. Woodlands often have higher carbon dioxide levels than open grassland, so many plants living in open areas have evolved mechanisms to overcome a shortage of carbon dioxide.

Solubility
UNO [17]
I think the molecules that will easily <span>dissolve in water based on polarity not on size would be as follows:

</span><span>CH and small 3 with H OH
</span><span>CH and small 2 with H OH

These molecules would indicate they are alcohols which are definitely soluble in water. Hope this helps. Have a nice day.</span>
