The table shows the crossing-over frequencies for three genes in the fruit fly Drosophila. The greater the frequency, the more likely that crossing over separates the genes. The gene for eye color (A), wing shape (B), and body color (C) are found on the same chromosome.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.

producers within ecosystems are essential as they are at the base of the food chain. plants are examples of producers. they use the process of photosynthesis to capture light energy and use it to convert simple inorganic substances (carbon dioxide and water) into organic substances (glucose).
