Needing help writing 2 paragraphs for the introduction portion and the aim portion in my lab report. Must be in your own words. Samples of what my professor used is listed below:

Introduction: Sensory receptors in the skin respond to different stimuli (e.g., pain, touch, temperature, etc.). These receptors are not distributed in the skin equally, but are concentrated in different areas of the body. The following two experiments will allow you to determine the relative distribution of the receptors for touch in the skin (Error of localization and two- point touch discrimination).

The error of localization test demonstrates how receptors in different regions of the skin are represented in the cerebral cortex. For example, every region of the skin corresponds to a specific area of the somatosensory complex in the cerebral cortex. The two-point discrimination test will assess the ability to perceive the number of stimuli placed on the skin. Areas that have a higher density of touch receptors are better able to distinguish between multiple stimuli than those with fewer touch receptors.

Part 1a-Aim: ERROR OF LOCALIZATION..To investigate the error of tactile localization of receptors in the skin
Part 1b- Two-point discrimination
Aim: To investigate the relative density of touch receptors in different regions of the body.
Part 1c- Two-point discrimination (spatial acuity in males vs females)
Aim: To investigate the spatial acuity in the pointer finger of males vs. females. Peters et al.
(2009) found that women perceived finer surface detail than men; a result that related to finger size. We will do a much simpler analysis to see if we find a similar relationship.

Hello, I am respectfully requesting help responding to the below discussion. I need to respond by applying the following:

Participate individually with meaningful and original comments in the dialogue of the posted discussion questions.

Ensure your posted content is written in your own words. Repetitive (redundant) answers, copied articles or portions of articles from Web sites, books, magazines and so on will not count towards participation

Cite properly and consistently and include all sources used for your responses

I choose pollution. Pollution comes in many forms whether its air pollution, water pollution, and land/soil pollution. Air pollution is caused by gases and toxins that come from factories. Water pollution is caused by oil spills or trash that people throw into the water, and soil pollution is caused by industrial waste that affects soil from getting its essential nutrients. All kinds of pollution can be harmful to plants, animals, and humans. Air pollution is the main pollutant in everyday life. Things such as cars, planes, power plants, and other human activities produce air pollution. "Pollution disturbs our ecosystem and the balance in the environment. "Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these. Water-borne diseases like cholera, diarrhoea have also increased in all places." A solution for the pollution would be having a big fine for people that pollute, fix the cars, planes, and power plants to where they don't give off carbon dioxide, and find a way to prevent oil spills into the ocean. Some other solutions for each would be:

Air Pollution:

"Seek advice from environmental professionals when locating exhaust outlet"

"Use smokeless fuel, such as gas and electricity"

"No outdoor cooking, e.g. hotpot & BBQ"

Water Pollution:

"Remove the accumulated bottom sludge regularly"

"Engage registered grease trap waste collector for regular cleaning and overhauling of grease trap"

"Keep an updated drainage plan in management office"

"Check the drainage plan before carrying out of drainage works to ensure correct drainage route
