Organisms can reproduce asexually or sexually. asexual reproduction in most organisms follows definite steps. { 1. fertilization 2. zygote forms 3. gamete production 4. sperm transported near egg} read the four steps above and put them in correct order. a) 1,2,3,4 b) 3,4,1,2 c) 1,3,2,4 d) 3,2,4,1

Why is it important to reduce the number of chromosomes in half when forming gametes for sexual reproduction?

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis

What molecules will be best used to compare different species with the exact same sequence of amino acids? why would two species have the same protein even if the molecules in question is different? (hint: transcription to translation to protein).
