Multiple choices :
A. test for chemicals that might poison fish and cause algae to grow
B measure the dissolved oxygen content in pond-water samples
C look for sources of pollution that may be affecting the pond
D measure the amount of light at various levels in the pond
Answer;
D. measure the amount of light at various levels in the pond
Fish in the pond feeds on the algae that grows in the pod.
Therefore; death of fish in the pond caused a large increase in algae populations.
Measuring the amount of light in the pond would not tell the student what caused the death of the fish in the pond.
The four components of biodiversity increase the stability of ecosystems and increase the resistance of ecosystems to harmful invasive species. Stability of ecosystem refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.
This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I. Homologous chromosomes – 1 inherited from each parent – pair along their lengths, gene by gene. ... The chromosomes now have genes in a unique combination
Answer:
No
Explanation:
If the earth was tilted, there would be small changes in temperature, but there will be no seasons. The Earth's axis is now inclined at around 24 degrees. This is the main reason for the changing of the seasons. The Northern Hemisphere is in the warm season when the Earth is slanted toward the sun, and the Northern Hemisphere is in the cold season when the Earth is slanted away from the sun. The cycle repeats itself every year because the Earth rotates around the sun at a known and generally constant rate. The sun is higher in the sky during the warm season, making it warmer, and lower in the sky during the cool season, making it colder.
Hope this helps :)
