Cynthia observed a cell with a pair of sister chromatids moving towards a given pose as a single unit and another cell with sister chromatids moving to opposite poles. What’s did she infer from her observation
Answer:
Anaphase I and Anaphase II
Explanation:
In anaphase I, homologous chromosomes go to opposite poles (thus the first cell was under anaphase I), whereas, anaphase II moves individual chromatids to opposite poles (thus second cell was undergoing anaphase II)
How many sets of chromosomes do you start out with and end with in mitosis?????
Answer:
In mitosis you start with the full amount of chromosomes 46 (also known as 2n or diploid). Then the resulting daughter cells also have the full amount of chromosomes present, 46.

Tillage can release pollutants in the soil and
increase erosion.
decrease erosion.
promote soil compaction.
promote fertilizer retention.
Tillage can release pollutants in the soil and increase erosion by the acceleration of the soil and wind speed.
How doesTillage can increase erosion ?
Tillage can split soil structure, pace the decomposition and lack of natural matter, boom the hazard of erosion, break the habitat of useful organisms and reason compaction.
Each of those capability effects negatively effect soil fine. A soil's overall performance is immediately associated with a soil's fine or health. Since tillage breaks the soil, it disrupts soil structure, accelerating floor runoff and soil erosion. Tillage additionally reduces crop residue, which assist cushion the pressure of pounding raindrops.

In Madagascar scientists have discovered a moth, xanthopan morganil praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin's orchid, angraecum sesquipedale. The orchid has a nectar - producing tube that is 27.9 cm long. How is the moth's proboscis size an adaptation for its environment?
The size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.
What do you mean by Adaptation?Adaptation may be defined as the process of modifying one's characteristics to better suit a situation and survive more efficiently.
The size of the tube that produces nectar is just 27.9cm long, while the length of the proboscis of a moth is 30.5cm. It easily consumes the nectar and gets energy for survival as well as reproduction.
Therefore, the size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.

In north carolina, demand for fresh water has increased dramatically. one of the main reasons for this is increased water use for agriculture. respond to the following in 3–5 sentences:
relate one effect of agricultural water use on north carolina's river basins.
relate one conservation strategy that would reduce the effect of agricultural practices on water quality.
Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
What are the effects of irrigation agriculture on river basins?Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.
