It’s answer C because of eutrophication
Answer;
Kingdom, Division, Class, Order, Family, Genus and Species
Explanation;
-The plant kingdom is divided into three divisions namely Bryophyta, Pteridophyta and Spermatphyta.
-Division Bryophyta includes mosses and liverworts. Division Pteridophyta includes the ferns and horsetails. They show a greater variety and a greater ability than bryophyte.
-Division Spermatophyta comprises all the seed bearing plants. They are familiar green plants which produce seeds through flowers or cones. The division spermatophyte consists of two main subdivisions: Gymnospermatophyta and Angiospermatophyta, which are the divided into classes and so forth,.
Answer: The answer is Simulation Games
Explanation:
Simulation games are games that are designed to imitate or closely simulate real-world life activities. The players are able to control characters in the game, they are provided with a simulated environment in which they can play. The characters in the game copy real life activities such as flying a plane, managing a city as listed in the question, cooking, interacting with others, attending school or going to work, etc.
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.
