Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake.

Web Search Strategies The Web may seem like a vast ocean when it comes to finding something you need. Thankfully, search engines can help turn oceans of information into small pools that make finding information easier. Before we dive in, let’s talk a bit about how search works on the Web. Search engines go out and try to account for every word on every webpage. All this information is then organized for easy reference. When you search for a word, the search engine finds all the pages where the word appears, and displays them in the search results. The problem is that there are often too many results.
