Answer:
through glacial deposits and ice cores
Explanation:
Answer:
GTP-bound form
Explanation:
Such a receptor may be associated with the GDP-regulated G-stimulant protein system. When the neurotransmitter binds to the receptor, the protein G-GDP complex is activated by separating its β subunit. When the ligand "sticks" to it, it releases GDP and allows GTP to bind. This form of the G protein that binds GTP, is the activated ("on") form of it. When it is "on" it releases signals into the cell. After a short period (seconds or less) the G protein hydrolyzes the GTP to GDP and itself "turns off".
Sponges are a type of aquatic animal whose body is covered in tiny pores called ostia. The ostia allow water, oxygen, and other nutrients to flow into the sponge's body, and for waste products like ammonia and carbon dioxide to exit their body. The respiratory system of a sponge is based on the process of diffusion.
The appropriate response is biochemistry. Eduard Buchner showed that aging can be achieved utilizing dead chemicals as opposed to living yeast. He built up that biochemical responses are conceivable outside living cells. He was awarded a Nobel Prize in the year 1907 for his discovery on fermentation.
A meteorologist studies the climate.
