Answer:
Hmm. There are more than 3 types of fossils. The 3 most common types of fossils are Mold (where an organism is buried in sediment and then decays, leaving an empty space. Cast (when minerals in rocks fill a space by a decayed oransim. and then trace were a dinosaur leaves a foot print.

Can i be marked brainliest? if not thats okay. :)
Answer:
Here are the answers:
a. 4 Cell determination as an issue in the *rest is missing*
b. 4 They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.
c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
Answer:
Humans
Explanation:
A new research now suggests that possibly the entire animal kingdom, including humans, shares important genetic mechanisms with sea sponges. Now published in the journal Science, the discovery has been made by a team of scientists led by Dr. Emily Wong from the Victor Chang Cardiac Research Institute and UNSW Sydney.
2)
it’s charge would increase by -1
Explanation:
The type of atoms is usually determined by the number of protons. Different isotopes of an atom differ in the number of neutrons only. The number of electrons, however, in neutral atoms is the same as that of the protons. Its charge is zero because the positive charge of the protons cancels out with the negative of the electrons. Adding an electron to a neutral atom, therefore, increases the negative charge of the atom by 1
