Answer:
D. How deep the lake is
Explanation:
The benthic zone is the zone that is at the bottom of the lakes. This means that the characteristics of this zone and weather photosynthesis will be a possibility depend on the depth of the lake. If the lake is deep, then the photosynthesis will not be possible in this zone as the sunlight will not be able to reach it, thus this zone will be very poor in organisms. On the other hand, if the lake is shallow and the water is clear, then the sunlight will be able to reach the benthic zone, thus providing the conditions for the process of photosynthesis, and it will be very rich in organisms.
Semi permeable membrane will allow something to pass through them and something not and it will allow on the basis of size particles
while differentialy permeable will include other factors also other than size and will depend on the need of the cell
this is the main difference between them

Answer:
A. Pseudopods
Explanation:
Amoebae use pseudopodia to move
Answer:
Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.
