Nitrogen in the atmosphere must be “fixed” before it can be used by plants. atmospheric nitrogen is “fixed” by

Explanation:

According to USA Testprep (Where the question came from), "Nitrogen is fixed or chemically combined with other elements to form a usable chemical compound. Plants are then able to use nitrogen in this form; they are not able to use it in its atmospheric form." I hope this helps those that try to find the answer.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati
