what occurs in the life cycle of a moss but not in the life cycle of a gymnosperm?
in moss, sperm and egg cells are produced after haploid spores are separated from the sporophyte plant.
in moss, sperm and egg cells grow in cones that are attached to the sporophyte plant.
in moss, sporophyte and gametophyte generations alternate.
in moss, when two haploid cells fuse, they form a diploid zygote that begins the sporophyte generation.

The correct answer is:

In moss, sperm and egg cells are produced after haploid spores are separated from the sporophyte plant.

Explanation:

The life cycle of most mosses starts with the discharge of spores from a capsule, which begins when a small, lidlike structure, called the operculum, degenerates. A single spore develops to form a branched, filamentous protonema, from which a leafy gametophyte forms.

hormones in blood stream

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
