Answer:
You can use either your answer or the sample answer you gave. You are so nice by the way!
Explanation:
THE FOLLOWING ARE TWO ANSWERS YOU CAN CHOOSE FROM
ANSWER 1:
The red crystals are compounds. This is because when the sample is heated, a GAS (element) is released and BLUE POWDER (element) is left. Two elements make up these red crystals. A compound can also be shown through color change - the RED crystals, when heated, turn into BLUE powder. Elements cannot be broken down into substances using physical force, like heating. So yes, this is a compound.

EITHER ONE YOU CHOOSE WILL BE CORRECT, JUST SAYING!
I'm sorry, but I would need to see the options.
Answer:
the <u><em>cell membrane</em></u> is an extremely pliable structure composed primarily of back -to- back phospholipids (a "bilayer")
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
