markers are types of non-lateral markers such as white and orange markings that
are used as navigation aids that give directions, warn of dangers and marks
controlled locations. Orange diamond shapes warns of dangers such as rocks,
stumps or construction.
Answer:
population that is unchanging
Explanation:
The right answer is D.
Spermaphytes, or seedlings, are the last to appear on earth. This group is divided into two sub-branches:
*The gymnosperms (Conifers) which are currently represented by about 600 living species. They are plants whose free eggs (not enclosed in an ovary unlike angiosperms) are fertilized directly by pollen. They are divided into: Cycads (Cycas, Zamia) and Ginkgoales (Ginkgo biloba).
*The angiosperms (vascular plants), plants most recently appeared on earth, know today their apogee. This group has more than 250,000 living species, herbaceous or arboreal and adapted to almost all the biotopes of our planet. These are typically the ones we call flowering plants. Among angiosperms, there is a distinction between monocotyledons and dicotyledons. The cotyledon is the first leaf (primordial or germinal leaf), constitutive of the seed, and which presents itself to germination. The seeds of monocotyledonous plants, therefore, comprise a single cotyledon; those of dicotyledons have two. (For information: conifers (or gymnosperms) have more, often ten to twelve).
B. 'peripheral proteins' are present, not 'peripheral steroids'.
