+ not having enough food for everyone
+ how many people migrate
+ birth/death rates
+ how much water there is
+ how much nutrients/minerals are available
+ how much trees/oxygen is available
It would be a heterotroph and a omnivore because it eats grains and meats and a heterotroph because it has to get food.
Answer:
D. archaeal membranes contain L-glycerol.
Explanation:
Archaea and eubacteria differ from each other with respect to the nature of membrane lipids. Lipids present in the membranes of the archaeans have the hydrocarbons derived from isoprene units. These hydrocarbons are branched and are attached to the glycerol with help of ether linkage. Ester linkages are present in eubacteria. The glycerol present in the archaeans is L- glycerol. Bacterial membranes have D-glycerol present in their lipids.
Answer:
Biocatalyst or enzyme
Explanation:
The Lactose is a disaccharide sugar or carbohydrate found in the milk and the milk products.
The breakdown of the lactase is very difficult but the presence of a protein molecule called lactase-phlorizin hydrolase or lactase makes the breakdown of the lactose int galactose and glucose easy.
Such protein molecules which increase the rate of reaction are called enzymes and since the breakdown of lactose is a biological process, therefore, the enzymes are also known as the enzymes or the biocatalyst they increase the speed of the reaction.
Thus, Biocatalyst or enzyme is the correct answer.
