Answer:

Collecting data  

Step-by-step explanation:

During the observation phase of the scientific method, scientists are collecting data.

They can't create graphs or perform calculations, because they are still collecting data, nor can they report results to a colleague, because they have none to report.

Answer:

collecting data

Explanation:

Collecting data is a systematic endeavor. There is dependent variable and we are gathering information about that variable. This step helps us to understand how the dependent variable behaves under controlled experimental conditions. Collecting data eventually helps us to test hypothesis, understand research questions and evaluate outcomes.

Crank

Molar mass:-

\\ \tt\longmapsto 14+3(1)=17g/mol

Now

\\ \tt\longmapsto Given\:mass=No\;of\:moles\times Molar\;mass

\\ \tt\longmapsto Given\:mass=17(2.5)

\\ \tt\longmapsto Given\:mass=42.5g

What characteristic of an element’s atoms always determines the element’s identity?
dmitriy555 [2]

!! ANSWER QUICK !!
kari74 [83]

Answer:

I can use a dichotomous key. It helps me classify objects by sorting it out with "yes" and "no" questions.

or

I can use a Punnett Square. It helps me classify what genes the offspring will receive simply by figuring out the recessive and dominant genes as well as the hetzygous and homzygous.

Now give an example of which ever chart you choose by drawing it if that is required. For the Punnett Square label each of the squares Top right Hetzygous, top left dominant, bottom left recessive, bot-tom right homzygous. And for the dichotomous key put a 5-7 length branch showing the animals that have fur, can breathe under water, what cannot or doesn't have those traits. or something similar

Hopefully this helps :)
