Astronomy Ranking Task: The Seasons
Exercise #4
Description: In the figure below six different locations (A - F) on Earth are shown during a particular time on
with the Earth being at its greatest amount of tilt toward or away from the sun for each i. e. a solstice). Note
that each location is also at the same latitude (north or south) of the equator.
•
First for each letter label (a) the hemisphere it is in AND (b) the solstice it would be experiencing.
A. Ranking Instructions: Rank the time it takes (from longest to shortest) for each location (A-F) to complete one full rotation.
Ranking Order: Longest time 1/
2_
3_
_4_
_5__6_
_Shortest time
Or, the time it takes each location to make one full rotation is the same.
(indicate with check mark).
Carefully explain your reasoning for ranking this way:
B. Ranking Instructions: Rank the maximum height (from lowest to highest) the sun would reach during the course of one full
rotation.
Ranking Order: lowest 1_
2_
3_
5_
6_
highest.
Or, maximum height reached at each location is the same.
(indicate with check mark).
Carefully explain your reasoning for ranking this way:

b

explanation:

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

looks like the answer is     c     to me!

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
