The study of fossil mammals is: micropaleontology
invertebrate paleontology
vertebrate paleontology
paleobotany
these are the chocies

The study of fossil mammals comes under vertebrate paleontology.

Explanation:

Paleontology is the study of fossils which tries to explain the evolution of organisms, their environment and interactions with each other. The various sub divisions of paleontology are vertebrate paleontology, invertebrate paleontology , micropaleontology, paleobotany, palynology etc.

The study of vertebrate fossils, from primitive fishes to the immediate ancestors of modern mammals is known as vertebrate paleontology. Invertebrate paleontology deals with the study of invertebrate animal fossils, such as molluscs, echinoderms, arthropods and annelid worms. Paleobotany studies fossil plants which includes the study of fossil algae and fungi in addition to land plants.  Micropaleontology is the study of microscopic fossil organisms, regardless of the group to which they belong.

Brainliest? I just want to move up a level in , so please. Lol not trying to sound so desperate.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7

cu2o

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
