1. two students measure the same sample (mass= 6.78 g) one student gets these measurements: 6.7, 6.66, 6.9, and 6.8 g. the other student gets 6.88, 6.88, 6.86 and 6.87 g. explain why the first student is more accurate, and the second is more precise.

2. using significant figures to reflect the uncertainty in each measurement, find the sum of the following measurements: 25.34 ml, 152 ml, and 4.009 ml.

The embryos of a bird, a reptile, and a mammal are similar in appearance. how does comparing the physical appearance of embryos of different species support the theory of evolution? a. it shows that these organisms share a common ancestor. b. it provides evidence that these organisms eat the same foods.c. it shows that these organisms share the same habitat.d. it provides evidence that these organisms suffered a genetic mutation.

Which is the most likely reason the writer of the play pygmalion chose to change the character of galatea from a statue to working-class woman?

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
