allsm [11]

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!!!

Can someone answer this pls??
Lunna [17]

Answer:

75% brown, 25% white

Explanation:

This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).

According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.

Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:

¾ or 75% brown and ¼ or 25% white
