Explanation:
Keep in mind active transport is always against the concentration gradient.
For active transport pumps or chaanel protiens needed so if these are pasaing through phospholipids than most probably it is passive transport.
Listen dear it is it is more important that movement is along or against the concentration gradient than what is moving if it is along concentration gradient than it is passive and if against gardient it is active
Simple to remember is energy ATP is used active other wise passive .

Answer:
3. haploid; diploid
Explanation:
Sperm is male gamete or often called male reproductive cell. During the process of spermatogenesis, reductional division (meiosis) occurs in the spermatocytes and spermatids are formed which further mature to sperms. Thus as a result of meiosis, their chromosome number is reduced to half and thus they become haploid cells. During oogensis, eggs are also formed as a result of meiosis which reduces the chromosome number and so eggs are also haploid.
When during fertilization, these two haploid nucleus of these cells fuse together, they form a diploid zygote.
