During a pulse-chase experiment, photographic emulsions were prepared at different times during the chase, and radioactive spots were detected at the following times and locations: 5 minutes: rough er; 10 minutes: golgi apparatus; 40 minutes: endosomes; 70 minutes: lysosomes; 140 minutes: lysosomes. which of the following conclusions can be drawn from these results

Pulse chase experiment was performed to find the secretory pathway of proteins inside the cell. The protein sorting and pathway of protein can easily be studied by the pulse chase experiment.

The molecule is labelled with radioactive component and its pathway is observed during the pulse chase experiment. The molecule reside  5 minutes in rough ER. After this 40 minutes in glogi apparatus. From the golgi apparatus the molecules moves towards the endosomes and resides for 70 minutes. The molecules then transferred to lysosomes in 140 minutes. This chasing explains the pathway of the molecule.

The pathway can be drawn is ER→golgi→endosome→lysosome.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.

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.
