Answer: hypothesized that the higher pH levels would increase the rate
of movement of the Artemia. The students placed the Artemia in petri dishes with 2 mm x 2
mm grids marked off on the bottom of the dishes. The students calculated how fast the Artemia
traveled in each pH (4-9) solution by counting the number of squares on the grid that the
Artemia crossed per second of timing.
The data collected from their experiment is presented below:

1. Using the grid below, create a graph based on the above data.
Explanation: yes
The periodic table only accounts for elements. It does not account for compounds, such as water.
Photosynthesis and chemosynthesis
Answer:
Three factors are used.
The availability of sunlight.
The distance from shore and
The water depth.
Explanation:
<u>Availability of Sunlight
</u>
The photic zone is the upper part of the ocean into which sunlight penetrates.
<u>Distance from Shore
</u>
The intertidal zone is the strip of land where the land and ocean meet and overlap, or the zone between high and low tides.
The neritic zone is the marine-life zone that extends from the low-tide line out to the shelf break.
The oceanic zone is the marine-life zone beyond the continental shelf.
<u>Water Depth</u>
The pelagic zone is open zone of any depth. Animals in this zone swim or float freely.
The benthic zone is the marine-life zone that includes any sea-bottom surface regardless of its distance from shore.
The abyssal zone is a subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight
Coalition might be more effective at the local level than the national level because the people at the local level usually share same culture and have a common goal.
- Coalition is a group that is formed by people or factions who partner and work towards a common goal. The main aim of coalition is to bring about a particular change.
- Coalition might be more effective at the local level than at the national level because the people at the local level usually share common goal. Also, the people at the local level usually share a common culture unlike the national level when different cultures are being considered.
In conclusion, people at the local level also understands themselves better which helps in an effective coalition.
