Answer: a . lunar regolith
Explanation: i just took the test
With the graph attached below you can determine when was the moment that
<span>Sally tripped and fell.
You can also see that they run for 4 minutes before starting to rest. Then, after resting 10 minutes (starting at the 9 min mark and ending at 14) they started running a bit, that's why the line is not at zero anymore. After moving a bit, between 15 and 16 min mark, they stop distancing for one minute. So the answer is: Sally fell at the 15 min mark.

Answer:
Law of Independent assortment
Explanation:
Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.
However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.
He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.
