Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.
Answer:
Bacteria and other microbes play an important role in the environment that is of decomposers which act in the last stage of the food chain. These microorganisms like bacteria cause the breakdown of energy-rich organic compounds. These compounds come from decaying matter of plants such as leaves or animals waste products and dead bodies.
I think it’s the second one.
The correct option is E.
NADPH provides the reducing power for the Calvin cycle reactions.
Calving cycle is a series of chemical reactions which take place in the chloroplast during the photosynthesis reaction. The reactions occur in the dark and it involves using NADPH as a reducing agent which add high energy electrons to carbon dioxide to form sugar.
Elephant tusks are considered to be enlarged and elongated incisors. One third of the tusk is usually located deep inside the elephant's head while the remaining two third of the tusk can be seen outside. The part of the tusk located in the elephant's head is made up of tissues, nerves and blood and it is called pulp cavity. The outside part of the tusk is made up of dentine with an outer cover of enamel. Elephants use their tusks as weapons of fighting and it is also used for foraging and digging.
