I am so sorry but I don’t know the answer, I just needed the points to ask a question myself
Phospholipids will form a bilayer in water because they contain hydrophobic (Water fearing.. in this cause water "hating") tails and hydrophilic heads (water loving). So they form a bilayer to remove the tails from water likewise, this satisfies the hydrophilic heads because they are still exposed to water.
A Gamete is a sex cell, this is a cell whose genes can be pass to future generations, and is hapliod is defferent to every other cell in your body because every cell in your body has 46 chromosomes 23 from your dad and 23 from your mom, but this cell has only 23, to be able to pass it to your childrens. This are your sperm for males and eggs for females.
Answer:
A boy brought a pair home as pets.
Explanation:
As small organisms will not have any major adaptations for moving quickly or flying to whole another country, hence it is not possible for the snail to travel from Africa to Florida with small animals. Getting stuck on the airplane wing is also not correct as they would have been wiped out by the wind pressure or might have not be able to survive. Hence, the most logical explanation for the snail to get transported to Florida is by a boy who might have brought them as a pet.
