Answer:
for number 2 its mosses or lichens
Answer:
Explanation:
The surface of smooth endoplasmic reticulum that faces the cytoplasm lacks ribbon hence the name smooth endoplasmic reticulum.
The surface of the rough endoplasmic reticulum facing the cytoplasm is studded with ribosomes hence the name rough endoplasmic reticulum.
Both are part of the endomembrane system
The smooth ER functions in the detoxification of drugs.
The rough ER due to the fact that it is students with ribosomes also functions in protein synthesis
The smooth ER coupled with the detoxification of drugs or excess alcohol also help in the synthesis of lipids.
Plant and animal cells are eukaryotic cells which have:
a cell membrane
cytoplasm
genetic material ( in the nucleus)
Bacterial cells are prokaryotic cells which have:
smaller structure (than eukaryotic cells)
cytoplasm
a cell wall
dna loop or small rings (plasmids)
hope this helps
Answer:
The frozen ground does not allow roots for large trees to grow
Explanation: characteristic of *severe cold climate regions* *especially treeless artic regions* and high mountain tops. Plant life must adapt itself to a *short growing season(e.g,shrubs and low lying plants adapt themselves to short growing season)* of about 60 days and to a soil that remain frozen for most of the year. Most tundra regions are covered with bogs, marshes, ponds and a spongy mat of decayed vegetation, although high tundras may be covered with only lichens and grasses. Vegetation of dwarf woody plants, grasses, sedges and lichens may be quite profuse in tundra despite the thin soil and short growing season.
Therefore, large trees cannot allow roots for large trees to grow in frozen ground but short shrubs and low lying plants can,to an extent .
