What is a limitation of Jillian's cell model?
Jillian made a model of an animal cell. She used a round
balloon to represent the cell membrane. She pushed
objects like marbles and rocks into the balloon to show
cell parts, then filled it with water to show fluid inside the
cell.
It does not make up the tissues of a living thing.
It does not show the functions of the cell parts.
It is larger than a real animal cell.
It is more complex than a real animal cell.

Which of the following statements is true? 1. the mantle of the earth is made of solid nickel and iron. 2. the crust of the earth is made of solid nickel and iron. 3. the inner core is made of solid nickel and iron.

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically

Hurry which of these is true about index fossils? a) are very scarcely found b) used as guides in relative dating c) found in the youngest layer of the rock d) used as reference points in absolute dating
