Answer:
Sporophytes were branched before the evolution of vascular tissues
In early land plants the gametophytes were branched and complex like the sporophytes
Explanation:
The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).
The answer is <span>A. presence of cell membranes.
A classification of living things can be based on many different characteristics but a presence of cell membranes is not one of them. <u>ALL living things have cell membranes.</u> So, <u>there could be no classification</u> of organisms with cell membranes and organisms without cell membranes.
On the other hands, based on mode of nutrition, organisms can be classified of autotrophs and heterotrophs. Based on presence of nucleus, organisms can be prokaryotes (without a nucleus) and eukaryotes (with the nucleus). Number of cells is base for classification of living things on unicellular and multicellular.</span>
Solution:
The ecosystem boundary of a drainage basin can be defined by the mountains, hills and valleys that determine where the water flows.
Since the Ecosystem is define as all the organisms and their physical and chemical environment within a specific area where energy and matter influence the distribution and abundance of organisms present.
Thus the right answer is mountains, hills and valleys that determine where the water flows.
A. concentration camps
B. other countries
<span>C. small German villages
</span>D. ghettos
The Germans never took the Jews to churches during the Holocaust.
