Some fish have a density slightly less than that of water and must exert a force (swim) to stay submerged. what force (in n) must a 53.0 kg grouper exert to stay submerged in salt water if its body density is 1013 kg/m3?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?
