Albert needs to determine the force of gravity on a 250 g ball. the force of gravity on a 1000 g ball is about 10 newtons.
albert measures the force of gravity on the 250 g ball, and finds it to be 4 n. he does not think that this measurement is correct. what should be the force of gravity on the ball?

a.
the force of gravity on the ball should be 0 n.
b.
albert's measurements are correct.
c.
the force of gravity on the ball should be about 10 n.
d.
the force of gravity on the ball should be about 2.5 n.

Indicate whether the following statements about the biases in the fossil record are true or false. a) inland species are more likely to be preserved than marine species b) organisms with hard body parts are more likely to be preserved than are those composed soft tissues. c) species that existed over a larger area are more likely to be preserved than species existing over a smaller area. d) organisms that lived very long ago are more likely to be found as fossils than organisms that lived relatively recently e) the fossils of larger organisms are more likely to be found than the fossils of smaller organisms
