Yes i think so . ;( i really domt have notiing else to type
<span>The cells of plants
and animals are similar expect for a few different structures like the shape of
the cells and cell wall. They differ in cell shape since animal cells are rounded
and it has irregular shape while plant cells have fixed shape which is
rectangular. Another structure is a cell wall. Animal cells don’t have cell wall
while plant cells have. Plant cell wall is a structure surrounding the cell
that provides a number of functions such as strength to support the plant, Flexibility,
Water-proofing, Barrier to pests, Protection against environmental stress, signaling
and sensing. </span>
First eliminate choices C and D since they both mention that fact 1 is crossing over ( which is also referred to as genetic recombination) . So you're left with A and B and the correct answer is B .
Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness, strength, and water-resistant properties. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from the deeper layers
Hope this helped!
Good luck :p
