<u>Abstract of this paper is </u>
The Okanagan Centre phase is the stratotype for marine oxygen isotope stage (MIS) four sediments (Okanagan Centre go with the flow) within the southern indoors of British Columbia, Canada. preceding work advised that those sediments report glacial and two interglacial cycles. This observe reports on particular sedimentological and geochronological investigations of lithostratigraphic units comprising the Okanagan Centre sequence, revealing successive deposition of subaqueous and subaerial outwash, a subglacial till and glaciolacustrine sediments at some point of MIS four. A limiting optical age of 113 ± 8 ka defines the base of this sequence. Sedimentological, paleopedological, optical courting and tephrochronological statistics from sediments near the middle of the series screen soil development (MIS three) in eolian sediments deposited on a river terrace overlying a deglaciated floor. within these sediments.

Answer:
A quarter of the sample.
Explanation:
Let the quantity at the beginning be T. If the element has a half-life of 1,000 years, it means that after 1000 years, T/2 (which represents half the initial quantity available) would have decayed, remaining T/2.
After another 1000 years (making 2000 years), T/4 (which represents have of the quantity left after the first 1000 years) would have decayed, remaining T/4.
This means that only a quarter of T would be left after 2000 years.
Answer:
Natural selection and selective breeding can both cause changes in animals and plants.the difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. for this reason selective breeding is sometimes called artificial selection.

Answer:
Cell Division. Read explanation
Explanation:
It wouldn't be any of the sex cells so that would take out gene activity and offpsring. The only thing that changes the somatic (body) cells would be the slowing of cell division which I would assume is the correct answer.
