The correct answer for this question is D. Due to changes over time, the
most accurate weather forecasts are short-term forecasts. Although
modern technology allows us to predict the weather with increasing
accuracy, the seven-day forecast and long-term forecasts provide nothing
more than a guideline and cannot be relied upon.
The answer is C. Soil is considered a non-renewable resource because it takes millions of years for soil to renew itself due to the long process of soil formation hence soil is easily degraded by human activity within a human lifespan. In the picture shown, the deforestation will cause the soil to be easily eroded by elements of erosion. This will lead to desertification of the region which will result in a domino effect on the rest of the forest.
Answer:
the process whereby nonsister chromatids exchange genetic material
Explanation:
Crossing-over is a unique phenomenon which occurs only in the prophase I stage of meiotic division i.e. meiosis I. It is the process whereby nonsister chromatids of homologous chromosomes (similar but non-identical chromosomes from male and female parents) exchange their genetic material.
This exchange between nonsister chromatids aids in genetic variation among species that reproduce sexually via meiosis. Hence, meiosis, which is peculiar to sexually-reproducing organisms is the only way that promotes genetic variation in species.
