ionic compounds when in the form of ions(in solution or molten state) would be attracted to positive or negative plates depending on the charge on the ion.Positive ion would be attracted to negative plate and negative ion would be attracted to positive plate. Whereas covalent compounds are neutral so they would be attracted to positive/negative plates. CH4,CH2Cl2,C2H2Cl2,CO2,O3 being covalent compounds do not produce ions so they would not be attracted to positive or negative plates. (CO3)2- (carbonate ion) being a negatively charged ion would be attracted to the (oppositely) positively charged plate. H2O although covalent compound is slightly polar having very small concentration of H+ (in the form of hydronium ions H3O+)and OH- ions thus these ions will be attracted to both the plates depending on their nature of charge.

Mandible Known as the lower jaw bone. Also forms the chin and sides of the face. (Largest, strongest facial bone.) Bone into which the lower teeth are attached. The only moveable facial bone; motion of this bone is necessary for chewing food (the first stage of the digestion process). Each side of the mandible has a condyle and a coronoid process. The condyle articulates with the temporal bone to form the temporomandibular joint Solution Mandible Known as the lower jaw bone. Also forms the chin and sides of the face.

Unculturable organisms are those that cannot be grown on current lab conditions. The presence of them on environmental samples can be identified by isolating them on medium in which they grow. For example, few bacteria can be isolated when grown on plain seawater rather than seawater added to nutrients. Likewise rare samples can be identified and isolated. 16s rRNA gene sequencing technique idemtifies them better. Through simulted environments and coculturing techniques these uncultured organisms can be isolated Limitations of PCR amplification of 16s rRNA is lethal to the organisms.

Such damage never happens during first pregnancy as there is no transference of blood during the 1st pregnancy. During the delivery of the first fetus(Rh+), Rh antigens from the fetus can enter into the mother’s(Rh-) circulation. As a response to this, the mother’s body would produce antibodies. These antibodies would harm the second child if the child is Rh+.

Please follow the data and description : Doubly linked list : In the filed of computer science, a doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links, that are references to the previous and to the next node in the sequence of nodes. The example that has been provides is the : 3(head)-----> 7 ----->5-----> 9-----> 1(tail) Now that we have a node defining the head and the tail of the list. And because they are double referenced this means we can easily add or remove items from the head and the tail. As there are given some lines of code that has to been predicted we follow it as : a) current = head; : This clearly indicates that the current position of the element is the head element which is the element 3 in the present case. So the current node element after the execution of the line is 3. b) current = current.next; : Now that the current element is the 3 which is the head so that the pointer is in the head element and the command now says that current position of the element is the next element to the current element. So by moving to the next element as this is possible in the linked list, we get the element as 7. So the current node element after the execution of the line is 7. c) current = current.next; : Now that the current element is the 7 which is the element next to head so that the pointer is in the node element and the command now says that current position of the element is the next element to the current element. So by moving to the next element as this is possible in the linked list, we get the element as 9. So the current node element after the execution of the line is 9. d) current = current.previous; : Now that the current element is the 9 and the command now says that current position of the element is the previous element to the current element. So by moving to the previous element as this is possible in the doubly linked list to move forth and backwards, we get the element as 7. So the current node element after the execution of the line is 7. e) current = current.next; : Now that the current element is the 7 which is the element next to head so that the pointer is in the node element and the command now says that current position of the element is the next element to the current element. So by moving to the next element as this is possible in the linked list, we get the element as 9. So the current node element after the execution of the line is 9. f) current = current.next; : Now that the current element is the 9 and the command now says that current position of the element is the next element to the current element. So by moving to the next element as this is possible in the linked list, we get the element as 5. So the current node element after the execution of the line is 5. g) current = current.previous; : Now that the current element is the 5 and the command now says that current position of the element is the p.

Generally the formula for an acid is a hydrogen atom bonded with either another atom that is an anion, such as Cl- (chlorine anion) or another molecule that is an anion, such as SO42- (sulfate anion). What makes an acid an acid is that the hydrogen cation can fall off the molecule, known as protonation, leaving behind a relatively stable anion. This anion is known as the acid\'s conjugate base. A strong acid, such as HCl, has a weak conjugate base. A weak acid, such as HF, would have a strong conjugate base. A strong acid is dictated by how much it protonates in water, that is, how much the H+ cation dissociates from the anion in water. In HCl\'s case, the acid protonates almost completely, making it a strong acid. The acidity of an acid is measured by the well known pH scale. As you go upwards in difficulty of chemistry, molecules with multiple hydrogens can have different acidities because when different hydrogens leave, they can form a more or less stable anion behind. I hope this helps!

Directives are JavaScript functions that manipulate and add behaviours to HTML DOM elements. Directives can be very simplistic or extremely complicated. Therefore, getting a solid grasp on their many options and functions that manipulate them is critical. There are many options that can be configured and how those options are related to each other is important. Each directive undergoes something similar to a life cycle as AngularJS compiles and links the DOM. The directive lifecycle begins and ends within the AngularJS bootstrapping process, before the page is rendered. In a directive’s life cycle, there are four distinct functions that can execute if they are defined. Each enables the developer to control and customize the directive at different points of the life cycle. The four functions are: compile, controller, pre-link and post-Link. The compile function allows the directive to manipulate the DOM before it is compiled and linked thereby allowing it to add/remove/change directives, as well as, add/remove/change other DOM elements. The controller function facilitates directive communication. Sibling and child directives can request the controller of their siblings and parents to communicate information. The pre-link function allows for private $scope manipulation before the post-link process begins. The post-link method is the primary workhorse method of the directive. In the directive, post-compilation DOM manipulation takes place, event handlers are configured, and so are watches and other things. In the declaration of the directive, the four functions are defined like this. .directive(\"directiveName\",function() { return{ controller:function() { // controller code here... }, link:function() { // post-link code here... } } }) Social policies are policies which are designed to address social issues, ranging from poverty to racism. Many governments have agencies which formulate and administrate social policies, and governments approach social issues in a variety of ways. Some countries often regarded as a very progressive model when it comes to social policy, with a number of far-reaching programs which are designed to promote equality in the European Union. Social policy reform can also take place outside the government, as seen when community organizations work to support disadvantaged citizens. Social policies include: government pensions, welfare for the poor, food stamps, affordable housing initiatives, health care, unemployment benefits, equal opportunityemployment laws, antidiscrimination laws, and policy initiatives which are designed to benefit disadvantaged people in society. For instance, many nations encourage their colleges and universities to accept students regardless of need, with the goal of giving people at an economic disadvantage the chance to go to college, improving their opportunities.

Answer: Option E IFN-Gamma is th most likely candidate for cytokinin x Cellular immunity mediated by T-cells, macrophages, and activity of Type-1 cytokines (interleukin-12 [IL-12] and interferon [INF] gamma) is necessary for maintaining the quiescence of chronic T. gondii infection. The production of IL-12 and INF gamma is stimulated by CD154 (also known as CD40 ligand) in human models of T. gondii infection. CD154 acts by triggering dendritic cells and macrophages to secrete IL-12, which in turn enhances the production of INF gamma by T-cells.In HIV infection due to immunosuppression opportunistic infection occurs withT. gondiidue to depletion of CD4 T-cells, impaired production of IL-12 and INF gamma and impaired cytotoxic T-lymphocyte activity.
