1.
Identify the type of precipitation that is not one of the main categories.
snow
sleet
<em>drizzle</em> ✓
hail
- It's a a mild fall of drops condensed hence , it's not a main category
- The four main categories are snow ,rain ,sleet & hail
2.
Which device is used to measure rainfall?
measuring stick
rain gauge ✓
rain meter
rain stick
- It calculates the precepated rain in a time period per unit area
3.
Which device is used to measure snow?
rain gauge
measuring stick ✓
measuring gauge
rain meter
- A simple measuring stick can measure the thickness of snow
Answer:
(A) rate=

st
Explanation:
The rate of chemical is a measure of the speed of a chemical reaction.
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.
During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.
Reaction rate = 
The regression equation is:
y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058
Inserting the values,
<span>
<span>
</span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748
y = 1.15 + 0.0629508 + 0.0060606 + 0.935748
y = 1.3125862
Answer:
x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
Answer: phosphates absorbed by plant roots
Explanation:
The inorganic phosphate ions are available in the rocks which are distributed into the soil by the withering process. The aquatic plants absorb the phosphate ions through their roots. The plants are consumed by the animals. The inorganic phosphate is converted by the plants and animals into organic form incorporated in the DNA.
So the DNA can be copied to make more of themselves.<span />
