Date: 12 Oct 2013 Subject: Assignment 3 Chapter 7 page 251 Exercises 1‚3‚4‚8 1. What does the shell ordinarily do while a command is executing? What should you do if you do not want for a command to finish before running another command? While the command is executing‚ the shell waits for the process to finish. Or sleeps 3. What is a PID number? Why are these numbers useful when you run processes in the background? Which utility displays the PID numbers of the commands you are running?

population has declined over the years‚ but one specific turtle‚ the Hawksbill Sea Turtle is on the critically endangered list. Hawksbill Turtles get their name because of their beak shaped jaw. Hawksbill Turtles have very pretty shells and unique patterns along their shells. “They have overlapping scales with 5 central scutes‚ 4 pairs of lateral scutes‚ and 4 prefrontal scutes”. (MarineBio.org). These turtles like to live near the surface so they are closer to the shoreline for breeding and closer

decorations and accessories. They made seashells into accessories for them to sell it. But don’t you know that aside from those things seashells can also be made into a much useful things. In addition‚ seashells are also used in making jewelry. These shells are made into smooth perfect spheres which‚ by themselves‚ could be mistaken to pearls. We are aware that the education is the most powerful key to succeed. And to support this‚ we need some facilities and materials for us to make it easier and clearer

causes reductions in ecological niches and brings about evolutionary processes with harmful outcomes. Shells in the ocean have calcification impeded by the increasing carbonic acid and carbonate ion concentration. The added carbon dioxide and the water from the ocean reacts with the calcium carbonate of the shells and turns the shell into bicarbonate which is not a part of the shell‚ thus breaking the shell down (PMEL 2017). Some shellfish are experiencing reproductive failure from the increase in acid

Humans VS Pagurus Berhardus What is a vacancy chain and how does it relate to people and animals? Hermit Crabs‚ several species of octopuses and cichlid fish live in and defend empty shells. Limpets hunker down in rocks‚ Maine and southern Lobsters occupy small caves in coral and rocks. The red-cocked woodpecker carves nest hollows out of the trunks of pine trees. As many of these animals grow larger and older they seek better suited shelters‚ creating vacancies for other animals. People do exactly

The Bohr Model An atom* is the smallest particle of an element that retains the characteristics of that element. Each of the known 118 elements has atoms that are different from the atoms of all other elements. This gives each element a unique atomic structure. According to the classical Bohr model‚ atoms have a planetary type of structure that consists of a central nucleus surrounded by orbiting electrons‚ as illustrated in Figure 1–1. The nucleusconsists of positively charged particles called

electrons in the Lewis Structure: One of the easiest ways to start drawing a Lewis Structure is to make a list of each atom in the structure and next to each atom record how many valence electrons it has and how many it needs to fill its valence shell. In covalent bonding the valence electrons in the molecule come from the valence electrons in the atoms that formed the bond. a. The number of valence electrons in any main group atom is equal to its group # (I‚II‚II‚IV‚V‚VI‚VII‚ VIII

Hardening of the shell in presence of Asian shore crab Describe the adaptation In the 1980’s the Asian shore crab arrived in the waters around New England‚ and it quickly became one of the most dominant crab species in New England (Science Daily‚ 2006). However‚ the blue mussel that is native to the are has evolved to defend itself against the dominant crab which eat the mussels by crushing their shells. The favorable adaptation of the crab is its ability to thicken its shell in when an Asian shore
