Answer:

The answer is B

Explanation:

Tree rings form because during each growth season new water and food conducting cells (tracheids) are added around the perimeter of the tree trunk. Cells in the spring growth tend to be larger with thinner walls than the previous set of cells produced at the end of the previous summer. Over the course of the growing season, successive rings of cells become smaller with increasingly thick walls. In winter, growth ceases and no new cells are laid down. Then when the new growing season begins, thin-walled large cells form again producing a clear line between the old wood and the new wood because of the difference in texture.

Tree rings provide a record of past climate because their width is determined by tree growth rate, which in turn is determined by environmental conditions. Since one ring is produced every year (usually) the ages of the climatic events can be worked out very precisely by counting back. Records from young trees, old trees, house and ship timbers and fossil trees can be tied together by identifying sections with the same sequence of climatic event, the records overlap in time where the climatic patterns they record match up.

Arisa [49]

The correct answer is C. Glacier

Explanation

In the image, you can see the water cycle, and there are four letters, A, in the part of the sea; B on the earth's surface; the C below the Earth's surface, and the D in the mountains. In the area where the D is, there are glaciers on the mountain peaks caused by the low temperatures in the area. In addition, a glacier is a mass of ice formed on the earth's surface by the accumulation of snow on mountain peaks, in Antarctica, the Arctic, and Greenland. Therefore, the correct answer is C.

What are the top 3 (SKY) universities in S.Korea?<br> Why are they so hard to get into?
Elden [556K]

Answer:

top 3 universities could be

1) Korea university

2) KAIST university

3) Seoul national university

Explanation:I think undergraduate studies may be much more competitive than graduate not only because the seats are limited but also because their standards of students with high school diplomas are really high with thousands of students applying each year and only few getting into those schools.

For explanation, average foreign students or korean students who studied abroad applying to SKY universities mostly have following documents:

-SAT1450 above or near to that score

-3 or more AP with all scores of 5

-2 or more SAT2 with all scores above 750 (800 for math)

-MUN or other debate competitions

-GPAs close to 4.0 out of 4.0

-IB with scores above 43 (not sure)

-plenty of school activities

-international or national competitions esp. math

-essay (formal)

-sports or other extra curricular activities

This is not applicable to all students, and universities do not specify those information but they are implied grades and qualifications of many students.

uh i don't know much tho, i hope it helps..
