Answer;
Seedless plant.
The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.
Explanation;
-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.
-These plants reproduce using haploid , unicellular spores instead of seeds.
-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.
Geologic time is divided into units based upon types fossils found in each area .
I hope that's help !
False: the dead sea is 8.6 times saltier than the ocean
It is more precise to illustrate biosphere as the global ecosystem rather than the global community as it just comprises all the living things in a specific region regarding their distinct species. However, when one talks about the ecosystem, one automatically incorporates both the nonliving and living things like water, soil, etc. So, it is more precise in saying the global ecosystem, when one is talking about the Earth biosphere.
As marine ecosystems constitute over 70 percent of the surface of the Earth, the influence of these ecosystems on the global food web is impressive. The oceans are an essential source of oxygen for the planet and are efficient in the recovery and room for carbon dioxide. The marine classes offer essential ecosystem services like the preparation of drugs, food, and livelihoods. They also support recreational projects and tourism all around the globe.
Messenger RNA, or mRNA, molecules are produced by the process of transcription from DNA molecules. During this process, complementary base pairing takes place. The bases present in the DNA molecule are:
Adenine, Thymine, Guanine and Cytosine. The complementary bases on mRNA molecules are:
Adenine (A) in DNA binds to Uracil (U) in mRNA
Thymine (T) in DNA binds to Adenine (A) in mRNA
Cytosine (C) in DNA binds to Guanine (G) in mRNA
Guanine in (G) DNA binds to Cytosine (C) in mRNA
