Answer from: josegalvan123jg69

D) the diploid sexual life cycle

Explanation:

This life cycle occurs in most algae and its main characteristic is the alternation of generations, alternating a gamete-producing haploid phase and a spore-producing diploid phase. This life cycle is characterized by the phases: Diploid zygote -> Mitosis -> Diploid adult -> Meiosis -> Sperm and haploid eggs -> Fertilization -> Diploid zygote.

We call the diploid phase sporophyte and its duration varies according to the species considered. In bryophytes the gametophytic phase is longer lasting than the sporophytic, while in angiosperms the sporophytic phase is the most lasting.

The sporophyte (2n) has spore producing cells. Spores are haploid, so there is meiosis in their production. The spores are released into the environment and when they find a suitable location will give rise to gamete-producing haploid organisms.

These gamete producers are gametophytes, and represent the gametophytic generation. The gametes merge into a diploid organism, the zygote, which grows and develops, giving rise to the sporophytic phase.

Afew buddies come over to your house to hang out. they notice you're struggling in school, perhaps you have to rely on to pass your class, but you can't absorb the knowledge. they could positively reinforce getting a tutor and working with you, dedicating more time to the areas of struggle and less on hanging out to better yourself.secondly, say you're the victim of bullying. you're afraid to tell an adult because of possible repercussions from the bully himself. your friends encouraging you and pushing you towards telling an adult for your safety is another example.
