1. Water has many unique properties that contribute to making Earth habitable. Describe all four of these unique properties of w
marysya [2.9K]

The properties are:-

1. Water is polar. Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons.

2. Water is an excellent solvent. Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it!

3. Water has high heat capacity. It takes a lot of energy to raise the temperature of a certain amount of water by a degree, so water helps with regulating temperature in the environment. For example, this property allows the temperature of water in a pond to stay relatively constant from day to night, regardless of the changing atmospheric temperature.

4. Water has high heat of vaporization. Humans (and other animals that sweat) use water’s high heat of vaporization to cool off. Water is converted from its liquid form to steam when the heat of vaporization is reached. Since sweat is made mostly of water, the evaporating water absorbs excess body heat, which is released into the atmosphere. This is known as evaporative cooling.

The polen grains in this plant causes asthama in man​
iragen [17]

Answer:

I hope this helps :)

Explanation:

Tree pollen is a common hay fever trigger. It’s the first pollen to be released during hay fever season, and levels are typically highest from late March to mid-May.

Around 95% of people’s hay fever is triggered by grass pollen, which tends to be highest between mid-May and July. In fact, there’s strong evidence that when grass pollen levels are high, people with asthma are more likely to need hospital treatment.

Hay fever can also be triggered by weed pollen, which is highest from the end of June until September.

Know your pollen triggers

You can be allergic to more than one kind of pollen across the year. Different pollens are released at different times, but our changeable weather makes it hard to predict exactly when. If you have hay fever symptoms all year round you might have non-allergic rhinitis.  

If you regularly get hay fever and take antihistamines, start taking them up to four weeks before you normally get symptoms. Starting them early means that when pollen starts being released, the medication has already built up in your bloodstream so you may be less likely to react.

If you usually use a steroid nasal spray, it can take up to two weeks to start working, so again, start using it before your personal pollen trigger is released.
