Question 1:
<u>Answer</u>:
The "first line of defence" in innate immunity is "Physical and chemical barriers".
<u>Explanation</u>
"Physical and chemical barriers" is first line of defence includes that are ready to defend the living organism's body from infection at any time . These barriers include your skin, cilia, tears, urine flow, mucus, stomach acid, friendly bacteria and white blood cells . Skin acts as a mechanical barrier as it does not allows all the organism to pass through it unless the skin is cut or open. Similarly mouth eyes, and nose are also the ways through with the disease causing organism can enter the body. The micro-organisms that entered through these pathways are trapped either in saliva or mucus and swallowed and later either killed in the stomach or flushed out via the urine. If this first line of defence is broken or damaged, the second line of defence inside our body will be activated.
Question 2:
<u>Answer:</u>
Histamine kinins, and interleukins are examples of inflammatory mediators.
<u>Explanation</u>:
Inflammatory mediators are identified in inflammatory bowel disease IBD.These mediators play an vital role in the clinical and pathologic characteristics of the disorders. Cytokines, that are released by macrophages in due to antigenic stimuli, are binded different receptors and produce endocrine, autocrine and paracrine effects. Interleukins are a subset of a large group of 'cellular messenger molecules' called cytokines that modulates the cellular behaviour. Interleukins are not stored within cells like cytokines but they are released immediately, in response to a stimulus. Once an interleukin has been secreted, it moves to the target cell and binds to it through a receptor molecule on the surface of the cell . This interaction triggers a sequence of signals in the target cell that ultimately leads to the alteration in the behaviour of the cell.

23. When the sperm cell then meets the egg, the 23 chromosomes that each sex cell have form the 46 total chromosomes that each human being has.

Answer: EDG
Explanation:
First, effortful processing is encoding that requires attention and conscious effort. This would be something like studying where you store facts in your mind for use later. Automatic processing on the other hand, is unconscious encoding of incidental information and of well-learned information. For example, I know what someone means immediately if they say it's noon. As for chunking, it is organizing items into familiar, manageable units. One perfect example would be my phone number. There are many different numbers, but its easier to manage when some are grouped together. Then there are mnemonics which are memory aids, especially those techniques that use vivid imagery and organizational devices. For example, I use the first letter technique (PEMDAS) to help me when solving math problems. Spaced or distributed practice is studying or processing with breaks to help understand concepts. For example, when I study, I take a five minute break every 20 minutes to help my brain cool down and be ready to learn more. Now, deep processing involves elaboration rehearsal which involves a more meaningful analysis. For example, giving meaning to different words or images and making them relatable.
