Need Help ASAP????<br><br> Farming:Good or bad for the environment? Persuasive Speech.
miskamm [114]

Answer:

<u>This is only my opinion</u> you may think differently

Explanation:

In my opinion, farming is good for the environment when it comes to organic farming since this farming practice fights global warning as well as erosion and it supports animals. Chemical farming can damage the earth since it used highly toxic pesticides and fertilizers and it alters plants to increase their numbers which I honestly prefer non modified food but in these days in time its everywhere sadly

How does lung volume control inspiration?
Nesterboy [21]
An increase in volume DECREASES the pressure in the chest (pressure and volume vary inversely when temperature is held constant -- Boyle's law). Gas can only flow from an area of higher pressure to an area of lower pressure. It can't go uphill -- ever. It can only go from high to low pressure. When the diaphragm and intercostals contract, the diaphragm flattens and the rib cage rises. That increases the volume of the chest. That increase in volume decreases the pressure inside the chest (temperature is held constant -- because the temperature of the chest cavity does not change appreciably. It remains at body temp.). Air then flows from the area of higher pressure (atmospheric) to lower pressure (intrathoracic). That continues until the pressures are equal.

When the diaphragm and intercostals relax, the chest cavity decreases in size, the pressure increases to above atmospheric, and gas flows again from the area of higher pressure (intrathoracic) to lower pressure (atmospheric) until they are again equal.

It has nothing to do with the concentration of oxygen. You can ventilate a lung with ANY gas. It has to do with the change in pressure and only the change in pressure -- which is a function of the volume of the chest cavity.

Discuss how heat stroke, acquired during extreme physical exercise, disrupts the feedback loop and the impact this disruption ha
Vera_Pavlovna [14]

Answer:

Heat stroke is acquired during extreme physical exercise when the environment is hot, strenuous activity, excess clothing and tight clothing, drinking alcohol and smoking during a hot season or environment,when you are dydrated and not drinking water. Some medication and age also add to having heat stroke.

It causes disrupts in the feedback loop because it doesn't form a circular chain. It can be both positive and negative chain. Feed back loop is known to be either negative or positive channel or pathway formed by an effects.

The impact and disruption it has on human physiology

1.it causes brain damage

2.it leads to death

3.it also causes vital organ damage

Explanation:when the environment is hot, it makes you heat up fast when exercising and increase your temperature because the atmospheric temperature is high,and when exercising in this condition without air conditioner to cool your surroundings it leads to heat stroke.

When wearing heaving clothing and tight clothing during physical exercise it makes you to not lose moisture and makes air not easily passed to you, this causes your body to heat up fast and thereby causing heat stroke.

When dydrated and not drinking water causes you to overwork you body and not cool it down, it leads to heat stroke.

Heat stroke causes brain damage, leads to death when not taken immediately or rush to the health center or hospital.
