Answer:

The correct answer is - root hairs.

Explanation:

Root hairs or absorbent hair are the very small tubular outgrowth present in the epidermis of the roots of the plant that helps plants in absorbing the water from the soil pores into the plants. Water is an essential reactant in the photosynthesis process.

By their elongation increases the surface of exchange between plants and soil for better absorption. The major function of the root hairs to absorb the water and the nutrients from the soil to the plant.

Assuming equal concentrations and complete dissociation, rank these aqueous solutions by their freezing points. K2SO4 NH4I CoCl3
katrin [286]
The substance that releases the greatest amount of ions will have the greatest attractive forces within its solution, resulting in a reduced freezing point.
K₂SO₄ yields 3 ions
NH₄I yields 2 ions
CoCl₃ yields 4 ions

Freezing points:
CoCl₃ < K₂SO₄ < NH₄I

If 2.9g of water is heated from 23.9C to 98.9C, how much heat (in calories) was added to the water?
tensa zangetsu [6.8K]

Answer:

Explanation:

we know that

ΔH=m C ΔT

where ΔH is the change in enthalpy (j)

m is the mass of the given substance which is water in this case

ΔT IS the change in temperature and c is the specific heat constant  

we know that given mass=2.9 g

ΔT=T2-T1 =98.9 °C-23.9°C=75°C

specific heat constant for water is 4.18 j/g°C

therefore ΔH=2.9 g*4.18 j/g°C*75°C

ΔH=909.15 j
