Answer:
The electrons being removed from glass.
Explanation:
Given the glass object became positively charged by rubbing with a silk cloth.
The protons are present in the nucleus and are not free to move. While the electrons are free to move and roam between objects. So, when a glass is rubbed with a silk cloth, the electron leaves the glass object that will make a positive charge on the object.
Mold fossils ( foddilized impression made in the sunstrate).
Cast fossils, formed when mold is filled in.
Trace fossils = ichnofossils (fossilized nest, gastroliths,
Footprint, burrow, etc..
Answer:
+1
Explanation:
For the equation to be balanced, the total mass number and the total atomic number on both side of the equation but be equal.
This is illustrated:
For the mass number:
Left side: 22
Right side: 22 + 0 = 22
For the atomic number:
Left side: 11
Right side: 10 + x
11 = 10 + x
Collect like terms
x = 11 - 10
x = 1
See attachment for further explanation.
quantity of light
Explanation:
The likeliest limiting factor that restricts phytoplankton to approximately the top ten feet of the ocean rather than deeper is the quantity of light available.
- Phytoplankton are plants and they are the major producers in bodies of water.
- The require the process of photosynthesis to manufacture their food.
- During photosynthesis, phytoplankton takes in carbon dioxide and water and uses light to produce food in the process.
- This life activity greatly relies on light.
- The upper part of the ocean usually from 0-200m depth is the photic zone.
- Deeper water is aphotic and receives little to no sunlight.
- The photic zone is the zone where light reaches in water.
- There is abundance of light in the photic zone.
