We will investigate several different pollutants during Lab 4. Identify which part of sea urchin external fertilization you think is MOST likely to be affected by this pollutant, and why. Pollutant: Spermicide Group of answer choices Affects: viable eggs surviving in the ocean because spermicide will damage and break the eggs. Affects: the egg dividing into a larvae, because spermicide hinders the ability of a cell to divide. Affects: viable sperm swimming to egg, because sp

answer; both surfaces of the membrane are nonpermeable

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

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.

the correct answer was location c, because earth is tilted away from the sun at this time
