Answer:

Explanation:

because the nerval system is for sending and capturing signals from the brain to monitor if you had a broken bone so your brain and nerves say you are feeling pain. on rare occasions the nerves will totally skip the pain part and send different information to your brain, like if you broke your finger, it would skip the pain and all you would see is a weird finger.

Pollination cycles do not really have any direct effect with the soil. Releasing moisture from leaves does replenish some water needed in the soil that is cycled back through the transport systems of plants but does not hold back soil. Photosynthetic activities only draw up nutrients, minerals, and water from the soil through roots.

Therefore, the often elaborate ROOT SYSTEMS are the answer. This is because the roots hold the plants in the ground (soil) and by this, the plants prevent natural disasters, artificial actions, and/or excess water to wash away soil. The roots help to reinforce the soil and hold it together.

Answer: Oxygen

Explanation:I hope it helps . i have breifly explained it .

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.

Planet X has a moon similar to Earth's moon.

Komok [63]

Answer:

Planet X has a moon similar to Earth's moon.

Which path would this moon's orbit take? 3

If for some reason, the planet is destroyed and no

longer exists, which path would the moon take? 2

Explanation:

There are none of these planets in our solar system. But they might exist in other star systems. There, some moons might escape their parent planets’ gravity and start orbiting their parent stars instead. That’s according to new computer simulations. Scientists have dubbed the liberated worlds “ploonets.” And, the scientists say, current telescopes may be able to find the wayward objects.
