Garbage buried in an engineered and sealed landfill can still contain all of the following except - leahate
- heavy metals
- groundwater
- methane gas

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

idk im sorry.
