The complete explanation of the immune response to a pathogen through the oral (oral-anus) and respiratory route is given below in explanation part .
Explanation:
In order to provide host protection against pathogens wherever they can enter or spread, the immune system can be seen as an organ distributed throughout the body. A collection of anatomically distinct compartments can be distinguished within the immune system, each of which is specifically adapted to produce a response to pathogens present in a specific set of body tissues. The basic concepts underlying the initiation in the compartment of the peripheral lymph nodes and spleen of an adaptive immune response. This is the compartment that responds to antigens that have dispersed through the blood or penetrated the tissues. The mucosal immune system (commonly represented by the MALT) is a second compartment of the adaptive immune system of equal size to this, and situated near the surfaces where most pathogens enter. Body cavities (peritoneum and pleura) and skin are two other distinct compartments. These compartments are characterized by two main characteristics. The first is that immune responses induced within one compartment are generally restricted to that specific compartment in terms of speech. The second is that by expressing homing receptors that are bound by ligands, known as addressins, which are specifically expressed within the tissues of the compartment, lymphocytes are limited to particular compartments. The body's mucosal surfaces are particularly susceptible to infection. Because of their physiological roles in gas exchange (the lungs), food absorption (the gut), sensory roles (eyes , nose , mouth, and throat), and reproduction (uterus and vagina), they are thin and permeable barriers to the interior of the body. Obvious susceptibility to infection is provided by the need for permeability of the surface lining of these sites and it is not surprising that the vast majority of infectious agents via these routes enter the human body.
When contemplating the immunobiology of mucosal surfaces, a second essential aspect to bear in mind is that the gut serves as a conduit of entry in the form of food to a large array of foreign antigens. The immune system has developed mechanisms to prevent, on the one hand, a robust immune response to food antigens and, on the other, to detect and destroy the entry of pathogenic organisms via the gut. The majority of the gut is heavily colonized by commensal microorganisms, which live in symbiosis with their host, to further complicate matters. In certain ways, these bacteria are beneficial to their hosts. They provide protection by occupying the ecological niches for bacteria in the gut against pathogenic bacteria. By synthesizing vitamin K and some of the components of the vitamin B complex, they also serve a nutritional role in their host.
Peyer's patches of the small intestine, the appendix, and solitary lymphoid follicles of the large intestine and rectum are the other major sites inside the gut mucosal immune system for the activation of immune responses. The patches of Peyer are an extremely important location in the small intestine for the activation of immune responses and have a distinctive shape, forming domelike structures that reach into the intestinal lumen. Specialized epithelial cells reside in the overlying layer of follicle-associated epithelium of the Peyer's patches. Instead of the microvilli present on the absorptive epithelial cells of the intestine, they have microfolds on their luminal surface and are known as microfold cells or M cells. By endocytosis or phagocytosis, M cells pick up molecules and particles from the gut lumen. This material is then transported to the basal cell membrane, where it is released into the extracellular space, via the interior of the cell in vesicles. This mechanism is referred to as transcytosis. The cell membrane of M cells is extensively folded at their basal surface around underlying lymphocytes and antigen-presenting cells that take up the transported material released from the M cells and process it for the presentation of antigen.

In saltwater, the water that surrounds a fish has a higher concentration of dissolved salts than is found in the fish's body cells. Which two methods allow the fish to maintain water balance? A. Pumping out salt through the gills B. Absorbing water into the body by osmosis C. Releasing only a little water in urine D. Taking in salts via food
Answers
The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.
In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:
1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.
2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.
By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.
These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.

We transformed E coli cells with a plasmid modified to contain a ‘virulence factor’ which would allow growth on media containing the antibiotic kanamycin (Kan). The plasmid confers constitutive resistance to ampicillin (Amp).
Assume you were given competent cells of known transformation efficiency (TE). Assume TE= 1x10[6] (note 10[6] means 10 to the power of 6). You want to have about 1000 colonies on the P-200 plate. How many nanograms of plasmid should you use in the transformation reaction? Select only one answer.
Answers
We need 1 nanogram of plasmid in the transformation reaction when the transformation efficiency is given for 1000 colonies on plate P - 200.
Given the value of transformation efficiency (TE) = \(1 * 10^6\)
Number of colonies on the plate P-200 = 1000
To calculate the amount of plasmid (in nanograms) required for transformation, we need to first calculate the number of cells required for transformation.
To get desired number of cells we multiply the transformation efficiency and number of colonies given such that:
number of cells = \(TE (1*10^6) * 1000 colonies = 1 * 10^9 cells\)
Since 1 nanogram of plasmid is equivalent to \(1 * 10^9\) cells, we can conclude that we need to use 1 nanogram of plasmid in the transformation reaction.

Very wet soil would be dangerous to plants because the plant roots can not respire.
Why would very wet soil be dangerous to plants?Plant roots need oxygen for the breathing. When soil is too wet or waterlogged condition, the oxygen concentration is reduced and small oxygen is absorbed by the plant roots. So when the plant's root can' breath or respire, they die and eventually the whole plant also die.

Answer:
About three-quarters of Earth's freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!
Explanation:
The first is the cryosphere which represents about 68.5% of all fresh water on Earth, primarily stored in ice sheets and glaciers.Cryospheric stores the maximum amount of freshwater. Therefore, option A is correct.
How cryospheric stores hold the largest amount of freshwater?The cryosphere is part of the Earth's surface where water is in its solid forms, such as snow, ice caps, and glaciers. Although the cryosphere makes up only a small portion of the Earth's water supply, it holds the largest amount of freshwater in the world.
One reason for this is that the ice sheets in Antarctica and Greenland contain a significant amount of freshwater.
