Would a hypothesis for example be “it is cloudy” and the prediction would be “it will rain” ? can predictions be wrong even if the hypothesis is correct ?

1st one is no, i think the second is no

Explanation:

hypothesis is an if-then statement and predictions are made based off the hypothesis

hypothesis ex: "if you get at least 6 hours of sleep, [then] you will get better grades on tests than if you get less sleep."

prediction: "i will get a lower grade if I get 2 hours of sleep than I will if I get 6 hours of sleep"

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.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
