1. shut down the factory
This is a suggestion that will not be implemented simply due to the fact that the factory is likely to be bringing profits and meeting the requirements of a specific product or products. Shutting the factory down will mean great losses, which makes this suggestion non-feasible.
2. Move the factory out of the city
First, "moving" a factory is not as easy as it sounds. For a factory to be set up, many factors are considered such as the availability of raw materials and transport cost. Moreover, the emissions will still not be lessened if the factory is simply moved.
3. Increase the height of the factory's chimney
If these emissions are harming the nearby environment, this suggestion will help to reduce those effects. However, the negative effects will inevitably occur if there is a high level of emission of sulfur dioxide occurring, such as acid rain. Therefore, this does not solve the problem, only changes its nature.
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.
This is false!
Carbon is found in many substances!
For example, we breathe out carbon (Carbon dioxide) and as a result, there is an amoung of carbon in the air.
Carbon is also found in many rock types, such as in coal.
Answer: Growing is capable to a certain living organism. Growth means getting larger in size, and for multi-cellular organisms this is done by making more cells. Plants have special tissues called meristems where growth occurs. Single celled organisms increase their numbers by dividing and making more cells like themselves.
Explanation:
Answer:
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
