Here are the answers to the three questions on the right side of the page, as for the left, those are your own opinions, remember?
- plate tectonics: a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
- three different types of late boundaries:Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
- crustal features formed at plate boundaries: Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.
hope this helps ^^
<span>The process of allowing substances into and out of the cell is controlled by the B. cell membrane.
Cell membrane is the semipermeable membrane surrounding a cell, meaning that it may let some substances into the cell, and remove the others from the cell.

Answer:
It is consider less sequentisl because
- It is accidental death of cells whereas Apoptosis is a programmed death.
- It is caused due to injuries or damage but Apoptisis is caused due to the breakdown of cytoskeleton by enzymes.
- It damages other cells when died due to harmful chemicals whereas when cell dies by Apoptosis the other cells it it up..
Answer:
cell membrane
mitochondria
lysosomes
ribosomes
Explanation:
Cell membrane is the boundary of animal cell which is responsible for the intake of nutrients from outside environment of the cell. Cell membrane is a semipermeable membrane which take nutrient through a process of diffusion and active transport. Mitochondria is also called power house of the cell in which glucose molecule is broken down and energy is released. Lysosomes is an important organelle of the cell which is responsible for the collecting and removal of waste material from the cell through cell membrane. Ribosomes helps in the production of proteins and enzymes needed by the cell for different activities.
