Answer:
F,T,T,F
Explanation:
1)false-(its a covalent bond)
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
2)True-(water is a polar molecule)
Water is a polar molecule because the positive end attracts particles of negative charge.
3)True
water dissociates to form hydrogen ions (H3O+) and hydroxide (OH-) ions
4)false
Lower pH number means stronger acid, higher pH number means stronger base.
1) occluding junctions
2) anchoring junctions
3) communicating junctions
Occluding junctions do not totally seal the space between cells and the resulting permeability varies greatly. I would say anchoring junctions are most likely with one of the other 2 junctions being least permeable.
First, weather is the atmospheric condition occurring over a short period of time in a relatively small location. Climate, on the other hand, is the overall environmental condition over extended periods of time. Next, the water cycle is when water from the surface evaporates as water vapor under high temperatures and condenses in the atmosphere under lower temperatures and precipitates back to the surface. In the event that water evaporates more than it condenses then the weather will be warm to hot, the ground will be relatively dry, and drought over extender periods of time may ensue. On the other hand, if water condenses and precipitates more than it evaporates, then there will be a rainy season, and may extremely lead to landslides and floods.
Answer: Whether the culprit were too much sunlight or not enough, if photosynthesis stopped, plants would stop converting carbon dioxide -- an air pollutant -- to organic material.
