Answer: mode of reproduction
Explanation: Phylum pteridophyte are vascular plants this means they are plants that possess xylem and phloem tissues. Phylum pteridophyte reproduce and disperse by spores. The dominant phase in pteridophyte is sporophyte.
Phylum bryophyte lack true roots and they are non-vascular plants (no xylem and phloem tissues). They reproduce via gamates, the dominant reproductive phase in bryophyte is gametophyte.
<span>The type of isolation that describes the
statement above where in the species are being spread out and far over the area
is broad geographic range, for the broad geographic range is having species in
a state that they are being isolated in a way of having them spread out in a
particular area but too far from each other, where it describes and are related
to the statement being said above.</span>
The answer could be the fact that all species posses 23 universal proteins. These proteins vary slightly in some DNA sequences but are pretty much the same. These proteins are responsible for tasks such as DNA replication and translation from DNA to proteins. These activities are crucial to all forms of life. The presence of these universal proteins suggest that modern life evolved from a single common ancestor.
Answer:
Which of the following are involved in the cycling of nutrients in nature?
I.Bacteria
II.Plants
III.Earthworms
IV.Humans
Bacteria, Plants and Earthworms
Explanation:
Bacteria, Plants and Earthworms plays vital role im nutrients recycling in nature, earthworm does this during soil burrowing which enables the soil to mix together easily and allow nutrients to circulate. Plants also helps through the practice of mixed cropping and shifting cultivation whereby different plant is planted every year as the case maybe.
