Over forty interstellar molecules have been found, ranging from simple OH radicals to molecules with over a dozen different atoms, including a few polycyclic. Their significance lies in that planets are formed from such nebulas( area of the cloud), so this tells us what may be found.

One of the four prominent symptoms of typhoid is coated tongue. Even before the onset of fever, the tongue appears furred, with centrally coated and a red margin around. There are other illness also which shows coated tongue, but with different appearance. In malaria, the tongue is uniformly coated whereas in candidia thrush, a thick white layer of which patch is formed. In typhoid, the patch is centrally located on the tongue surrounded by a red margin. During the first week of typhoid, the dorsum of tongue is covered with a thin dirty white fur, which occurs due to the toxins released by the pathogen. The coat gradually clears from the tip and edges and completely disappears by the thid week of infection, leaving a glazed, dry or smooth red tongue. By observing the coat pattern, the Doctor would have diagnosed the fever well in advance. Solution One of the four prominent symptoms of typhoid is coated tongue.

Meselson and Stahl in 1957 gave experimental evidence that each DNA strand served as a template for new DNA synthesis, a process called semi-conservative replication. At that time, there were three proposed models for DNA replication put forward by the scientific community after DNA structure had been discovered- Semi-conservative, conservative and dispersive replication. Semi-conservative replication: In this model, the two strands of DNA unwind from each other, and each acts as a template for synthesis of a new, complementary strand. This results in two DNA molecules with one original strand and one new strand. Conservative replication. In this model, DNA replication results in one molecule that consists of both original DNA strands and another molecule that consists of two new strands with exactly the same sequences as the original molecule. Meselson and Stahl used the density gradient sedimentation experiment (done with the E.Coli bacteria) to establish that DNA replicates using the semi-conservative model of replication as follows: Results of analysis: Solution Meselson and Stahl in 1957 gave experimental evidence that each DNA strand served as a template for new DNA synthesis, a process called semi-conservative replication.

Introduction One of the key goals for the Windows Subsystem for Linux is to allow users to work with their files as they would on Linux, while giving full interoperability with files the user already has on their Windows machine. Unlike a virtual machine, where you have to use network shares or other solutions to share files between the host and guest OS, WSL has direct access to all your Windows drives to allow for easy interop. Windows file systems differ substantially from Linux file systems, and this post looks into how WSL bridges those two worlds. File systems on Linux Linux abstracts file systems operations through the Virtual File System (VFS), which provides both an interface for user mode programs to interact with the file system (through system calls such as open, read, chmod, stat, etc.) and an interface that file systems have to implement. This allows multiple file systems to coexist, providing the same operations and semantics, with VFS giving a single namespace view of all these file systems to the user. File systems are mounted on different directories in this namespace. For example, on a typical Linux system your hard drive may be mounted at the root, /, with directories such as /dev, /proc, /sys, and /mnt/cdrom all mounting different file systems which may be on different devices. Examples of file systems used on Linux include ext4, rfs, FAT, and others. VFS implements the various system calls for file system operations by using a number of data structures such as inodes, directory entries and files, and related callbacks that file systems must implement. Inodes The inode is the central data structure used in VFS. It represents a file system object such as a regular file, directory, symbolic link, etc. An inode contains information about the file type, size, permissions, last modified time, and other attributes. For many common Linux disk file systems such as ext4, the on-disk data structures used to represent file metadata directly correspond to the inode structure used by the Linux kernel. While an inode represents a file, it does not represent a file name. A single file may have multiple names, or hard links, but only one inode. File systems provide a lookup callback to VFS which is used to retrieve an inode for a particular file, based on the parent inode and the child name. File systems must implement a number of other inode operations such as chmod, stat, open, etc. Directory entries VFS uses a directory entry cache to represent your file system namespace. Directory entries only exist in memory, and contain a pointer to the inode for the file. For example, if you have a path like /home/user/foo, there is a directory entry for home, user, and foo, each with a pointer to an inode. Directory entries are cached for fast lookup, but if an entry is not yet in the cache, the inode lookup operation is used to retrieve the inode from the file system so a new directory entry can be created. File objects When an inode is opened, .

Higher lattice energies imply stronger bonding between the ions. This means that they will hold on to each other more strongly so that the polar water molecules will have a harder time separating them and thus dissolving them I would expect that a cation with a high charge density (smaller size for the same charge) would attract more polar water molecules and be more strongly hydrated.

Connection may be defined as connectivity between many devices which can create a network, where we can send or receive data or any other informative signals that can used for some matter. There are many devcices used for creating connections in a network such as router, switches, hubs, bridges and etc etc. Here available port are being connected then that port remains in forwarding state mainly when we talk about switches. These ports become main port of that particular switch and they are kept in forwarding state and these ports send and receive signals from other ports. basically switches sends frames thats layer-2 data. Talking about available ports we have TCP and UPD ports as well, where UDP stands user datagram protocol and TCP stands for transmission control protocol, both these protocols are in Transport Layer on OSI model. where TCP is connection oriented protocol and UDP is connection less prototocol. if u have made connectivity where TCP is enabled then that connectivity mkes it sure that data should arrive anyhow by receiving acknowledgement from end devices where as in UDP it is not necessary that ack should be recieved or not then accordingly connections are made.

Allopatric speciation occurs by seperation of organisms by geographic isolation. Allopatric speciation may occur by migration. Since, the gene flow between organisms is inhibited, the geographically isolated organisms form into two separate species due to adaptations to new geographical environment. Allopatric speciation is most common type of speciation observed in various organisms. Speciation may occur in population inhabited in same geographical area but exhibit reproductive barriers. Such speciation is known sympatric speciation and it is rare and it may result in polyploidy. Solution Allopatric speciation occurs by seperation of organisms by geographic isolation.
