The similarities are...
- they both have DNA chromosomes (although prokaryotes have DNA chromosomes in the form of a single stranded loop and eukaryotes have DNA chromosomes that are linear and thread like)
- they both have ribosomes (although ribosomes in prokaryotes are scattered in the cytoplasm and ribosomes in eukaryotes are either attached to the rough ER or free in the cytoplasm)
- they both have cell membranes
- some prokaryotes (bacteria) and some eukaryotes (fungi, plants and some protists) have cell walls
Desertification extends beyond the expansion of existing deserts to include land degradation due to human activity in drylands. Land degradation destroys or reduces the productivity of the soil, and is caused by excessive and unsustainable activities such as deforestation, overgrazing, poor land management, soil salinization, and soil erosion.
Sure hope this helps you :D
One of them i think is biolorgy with 5th and 6th
Answer:
the correct option is E.
Explanation:
in this case the shrew occupies the level of both secondary and tertiary consumers.
as the shrew eats spider( a secondary consumer) so it is a tertiary consumer but it also eats snails( a primary consumer) so it is therefore a secondary consumer also.
so the shrew occupies both secondary and tertiary consumer trophic level.
