In the embryos of a typical dicot and a grass, true homologous structures are:Immersive Reader (1 Point) (a) Coleorhiza and coleoptile (b) Coleoptile and scutellum (c) Cotyledons and scutellum (d) Hypocotyl and radicle.

(C) Cotyledons and scutellum

Explanation:

Among the given choice, then embryos of typically dicot and grass, true homologous structure which are called as cotyledons and also scuttellum

The scutellum is cotyledon of monocot seeds and the cotyledon found in the part of the monocot seeds and it obtain more portions of embryo in a fine manner

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
