The answers A(: just took the quiz
Answer:
Hey there.
<em><u>There are three types of scientific investigations: descriptive, comparative, and experimental scenitific investigations.
</u></em>
<em><u></u></em>
fist we have <em><u>Descriptive</u></em> scientific investigations.
Descriptive investigations use careful observations and measurements to develop findings.
Then we have <em><u>
comparative </u></em>Investigation.
comparative investigations Involve collecting data on different populations/organisms, under different conditions (Times of year, locations), to make a comparison. for Example, Using a hand lens to examine the color and texture of four different rocks.
Lastly we have <em><u>experimental</u></em> scientific investigations.
Experimental investigations involve a process in which a "fair test" is designed and variables are actively manipulated, controlled,
I hope it helped!!!

Answer:
C) Selective and differential medium.
Explanation:
Selective Medium:
A media contains specific ingredients which are required to promote the growth of microorganism and inhibit the other microorganisms to grow is called selective medium.
Differential Medium:
A media contains specific ingredients which differentiate the same group organisms or closely related organisms is called differential medium.
NaCl is used in media to promote the growth of Staphylococcus aureus and inhibit the growth of other gram positive and negative bacteria.
A yellow halo color shows the bacterial fermentation of sugar which will distinguish Staphylococcus aureus with other strains.
So, it will be selective and differential medium which will allow to grow Staphylococcus aureus and differentiate with other bacteria.
Answer:
C. local endemios
Explanation:
The most easily measurable distribution pattern in species can be considered the one at the local endemios. The reason why the local endemios are the easiest for measuring the distribution is because they live in small area, and only in that particular area, nowhere else in the world. This makes it very easy for measuring their distribution, as the area in which they live is very limited, has clearly defined natural borders, and all of the population is located in there.
