E-learning - Assignment Example Education is available all the time provided there is internet access and all the student need to do is to access the internet and start learning. Convenience is also achieved when using internet learning in that students do not have to be in a classroom to learn. E- Learning offers consistency in learning because students do not depend on different instructors. Relying on different instructors has the potential giving students different education depending on the financial capabilities or gender just to name a few factors, which may discriminate against poor students (SyberWorks, 2010). Educational material on internet learning is consistent irrespective of social class, and this minimizes inequality. Internet education offers a flexible way to learn depending on the requirements of students. This implies that that education is self-paced and the students can take time to understand the topics that are hard for them (Berman, 2006). Since the technology requires some skill, students as well as teachers have problems when uploading assignments and taking tests. Problems with internet and computer processing speeds are also obstacles that hinder use of internet learning. Proper education requires people to interact so that they can share feelings and information freely. Internet education lacks this personal touch to education and it can be a limiting factor to good education. Internet learning does not control the-learning environment hence chance of academic dishonesty is high. Class attendance is not necessary and absenteeism is prominent since irresponsible students have high probabilities of skipping classes. It is also not possible to tell who took a test and cheating is likely to occur, which is detrimental to education success. Some skills cannot be taught using internet learning since at times instructors are necessary so that they can influence necessary

CELL BIOLOGY - Essay Example In the first set, all hybrids with thiolase residue 100 intact have been imported into the peroxisome, and those lacking residue 100 or more remain in the cytosol. In the second set, all hybrids with residue 125 or greater have been imported into the peroxisome, and those lacking residue 125 or lesser remain in the cytosol. 3. In the absence of hormones, protein B binds to protein A in the cytosol (immediately after translation of protein A in the cytosol). This binding prevents access to the nuclear transport machinery. This can happen in many ways, two of which are described here: protein B may mask the nuclear localisation signal (as in the case of the hsp90 - steroid hormone system), or protein B may anchor protein A in the cytosol. In each case, the binding of the hormone to either protein causes dissociation of the two proteins, and protein A has access to the nuclear transport machinery. Thus, in normal cells, protein B is always found in the cytosolic extract, whereas the presence of hormone causes protein A to be found in the nucleus, rather than the cytosolic extract, where it is seen in the absence of hormone. 4. A. The protein enters the ER and goes through the default pathway (ER->Golgi->Cell Surface). This is because ER import is co-translational, whereas nuclear import is post-translational. Thus, before the nuclear import signal can be recognized, the protein is already within the ER lumen. B. The protein is imported into the mitochondria. This is because the nuclear export signal is different from the nuclear import signal, therefore the protein never enters the nucleus, and the mitchondrial import signal is recognized in the cytosol ii) The chances of fusion are increased, whenever the same protein (either Y or Z) is present on both donor and target membranes. Thus, when none of the two are present on both, the chances of fusion is 50% of the maximal, when either Y or Z is present on both membranes, chances of fusion increases
