The early suggestion that oxygen liberated from plants during photosynthesis comes from water was?
The early suggestion that the oxygen (O2) liberated from plants during photosynthesis comes from water was first published by Melvin Calvin, who also discovered the Calvin cycle. It was confirmed by experiments using oxygen-18 (18O).
What came first in evolution cellular respiration or photosynthesis?
Cellular respiration likely evolved before photosynthesis. Early prokaryotic organisms likely developed cellular respiration to generate energy from organic molecules. Photosynthesis evolved later in some prokaryotic organisms as a way to use sunlight to make energy.
Where does a plant get its energy for photosynthesis and what is the energy transformed into after photosynthesis is complete?
They produce glucose which is then used for cellular respiration. (Glucose is chemical energy, it has high energy bonds, which when broken in cellular respiration produce a net of 38 ATP (adenosine triphophate))
How do animals find water in the desert?
Desert animals are specially adapted to the dry conditions. Most of them do not need to drink water, but obtain sufficient moisture from the foods they eat. Some desert animals burrow down deep to find water. Others are specifically "shaped" to collect water. For example, the body of the thorny devil in Australia is completely covered in sharp spikes which actually collect the moisture that condenses in the early morning (or the occasional rains) and channel it directly down towards its mouth.
What prevented early plants from moving far from water A They were angiosperms B They reproduced asexually C They were sporophytes D They dried out easily?
What prevented early plants from moving far from water is that they dried out easily.
What is a camels main food source?
Camels Feed On Desert Food Like: .Cactus .Grass .Desert Plants
Do desert animals hunt in early morning?
Some desert animals hunt in the early morning, some early evening while others hunt at night. Those that hunt in the morning and/or evening are called crepuscular. Those that hunt at night are nocturnal.
What is the desert climate in the morning?
The hot desert is quite cool and comfortable in the early morning hours but as the sun rises higher it gets very hot quite quickly.
Will dawn harm flowers?
Dawn itself does not harm flowers; in fact, the early morning light can be beneficial for plants, providing them with essential sunlight for photosynthesis. However, if there are extreme temperature drops or frost during dawn, it could potentially harm sensitive flowers. Generally, regular morning conditions are favorable for flowering plants.
Why does a town in the desert rarely experience early morning fog as compared to a town along the coast?
no .
Why is watering plants grass in the early morning a way to conserve water?
Smaller amounts of water evaporate in the cool morning.
What time of the day would a person see many animals in the desert?
Many animals in the desert will be most active in the early morning, late evening and at night.
What time does the desert wake up?
The desert never sleeps. Some animals are active at night, some in the early hours of the morning and others are active during the day.
Where is 95 percent of the desert tortioses life spent?
The desert tortoise spends as much as 95% of its life in a burrow to escape the harsh desert climate. It only emerges in the early morning hours to feed.
Why it is good practice to water plants in the evening during summer and early in the morning during winter?
watering in the evening usually prevents the water evaporating, and early morning is to prevent it from frosting/freezing up...
What time of day are dissolved oxygen levels the lowest?
Dissolved oxygen levels are typically lowest in the early morning hours just before sunrise. This is because during the night, plants and algae consume oxygen through respiration but do not produce oxygen through photosynthesis.
The early suggestion that oxygen liberated from plants during photosynthesis comes from water was?
The early suggestion that the oxygen (O2) liberated from plants during photosynthesis comes from water was first published by Melvin Calvin, who also discovered the Calvin cycle. It was confirmed by experiments using oxygen-18 (18O).
