Many kinds of animals eat blackberries. Which of the following will most likely happen to the seeds of a blackberry plant after
faltersainse [42]

Answer:

The seed of the blackberry will be released in the faeces of the organisms. The seed of the blackberries will be distributed to different locations. When the seed will be dropped to a favourable location, the seed will germinate and a plant will grow from it. In this way, seeds are able to be dispersed at more favourable locations via animal sources. Hence, they will have better chances of growing in different areas.

When the human body is exposed to extreme cold, hypothermia can result and the body’s temperature can drop to 28.68°C. Convert t
salantis [7]

Answer:

299.83°K

Explanation:

So, kelvin is a means of measuring temperature, as the question implies. To convert Celsius, one form of measuring temperature, to Kelvin, another form of measuring temperature, we must know the conversion median. Our median is that 0°C = 273.15°K. So, now, as we know that 0°C = 273.15°K, 26.68°C = 273.15°K + 26.68°. Because 273.15K might as well be zero degrees celsius (according to our median 0°C = 273.15°K), we simply add 26.68° to 273.15K and get 299.83°K

Calculate the molar solubility and the solubility in g / l of agi at 25°c. the ksp of agi is 8.3 × 10−17.
Bond [772]
Answer is: solubility of silver iodide is 9.11·10⁻⁹ M.<span>.
silver iodide in water: AgI(s)</span> → Ag⁺ + I⁻.<span>
Ksp = 8.3</span>·10⁻¹⁷.<span>
[Ag</span>⁺] = [I⁻] = x.<span>
Ksp = [Ag</span>⁺] · [I⁻].
8.3·10⁻¹⁷ = x².<span>
x= √</span>8.3·10⁻¹⁷.<span>
x = [Ag</span>⁺] = [I⁻] = 9.11·10⁻⁹ mol/L.<span>
