Neko [114]

Answer:

in my oppinion its call a  

source of pergisol

Explanation:

What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.

Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.

What are the three primary factors that affect the rate of photosynthesis
kykrilka [37]

Answer:

Light; Carbon dioxide; Temperature

Explanation:

Light; There would be no photosynthesis if light is not present. The rate of photosynthesis increases with light intensity up to the certain limit that plant needs for photosynthesis.

Carbon dioxide; Without carbon dioxide photosynthesis is not possible. The rate of photosynthesis increases with carbon dioxide level up to the certain limit that plant needs for photosynthesis.

Temperature; Too high temperature will denature the plant photosynthetic enzymes and photosynthesis will be too slow at low temperature

lisov135 [29]

The heart rate would increase the brain would be aware that there may be more sudden noises or events your adrenaline would be pumping and your quick twitch muscle fibers would probably be tense or contracted ready to make quick sudden movements if necessary and your hairs would stick up i guess as extra senses for if something would touch you.  

Explanation:

not to mention but by the time you are startled your senses would probably be heightened due to you being  aware of your surroundings such as you would be constantly looking around you would hear better and probably move quicker for a short period of time due to pumping adrenaline.
