I'm 100% that the answer is D, thermal conductivity.
It was either C or D but D makes more sense than C does

Answer:
C. Only bacteria can reproduce outside a host.
Adenine always pairs with Thymine, and Cytosine always pairs up with Guanine in DNA. When dealing with RNA, however, Uracil replaces Thymine. So in RNA, A pairs with U and C pairs with G. (just a fun fact) :)
Answer: 200 seeds will be yellow.
Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.
In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., <u>200 seeds will be yellow</u>.
Answer:
1. Obtain two identical containers and dry sand.
2. Shape equal amounts of sand into a "slope on the side of" each container.
3. Spray water on the sand in one container. The sprayed water represents "rainfall"
.
4. In the other container, "place ice cubes to melt on the sand. This represents snow or glaciers."
.
5. Observe and record the changes in the sand.
6. Analyze differences between the two containers.
Explanation:
Mine hasn't been graded yet but I'm pretty sure this is the right answer. I'll come back once it's graded and say.
