Sleepwalking will most likely occur during which part of the night?

2 answers:

6 0

Sleep walking most often occurs during deep non-REM sleep.
Sleep walking is a sleep disorder characterized by walking or other activity while asleep. The normal sleep cycle involves distinct stages from light drowsiness to deep sleep. In Rapid eye movement (REM) sleep, the eyes move rapidly and vivid dreaming is most common. During the night, there will be several cycles from non-REM and REM sleep.

Sleepwalking will mostly occur in the non_REM stage of sleep. These are stages 3 and 4 of the sleep cycle. Most often sleepwalking occurs early in the night. Occasionally, sleepwalking happens in REM sleep close to early morning. Sleepwalking is most common in children 6 to 12 years old.

Which observation would provide indirect evidence that supports a hypothesis that the bubbles are o2 ?

zhuklara [117]

Explanation:

D. An increase in bubbles on the plant when it is moved under a brighter light.

The rate of photosynthesis increases with light intensity.

The process of photosynthesis is energy-storing, it converts light energy into chemical energy, which is stored in the bonds of glucose. Thus an increase in light intensity would increase the rate of photosynthesis, and more O2 bubbles would be produced as waste.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

Occurring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage molecule ATP through an electron transport chain.

This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

Negative impact humans have on the world's rainforest

Dovator [93]

Answer:

The human impact on the Amazon rainforest has been grossly underestimated according to an international team of researchers. They found that selective logging and surface wildfires can result in an annual loss of 54 billion tons of carbon from the Brazilian Amazon, increasing greenhouse gas emissions.

FILL IN THE BLANK!

ANTONII [103]

Answer: receives the thermal energy

Explanation:

The cryosphere can be defined as the land which is covered with the surface of ice in the solid form in the form of sea ice, river ice, snow, ice glaciers, ice sheets, frozen water, and others. When the ice on the land receives the thermal energy from the sun or any other source like radiation then it melts into water and it becomes the part of the water body in the form of the hydrosphere.

Why is the sun considered the ultimate source of energy for life on earth?

Svetach [21]

<span>b. photosynthetic organisms provide energy for other organisms on earth.

B is the most suitable answer as photosynthetic organisms get their energy from the sun, and other organisms get their energy from photosynthetic organisms, so the sun is the source of energy for all life.</span>
