the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Answer: The Heart stage.
Explanation:
Embryonic development or embroyogenesis refers to all the process that take place after the fertilization of ovule to give rise to develped plants embryo.This occur during single or double fertilization.
There are six stages of embryonic developments and they are; the two cells stage, eight cells stage, globular stage, Heart stage, torpedo stage and maturation stage.
The Heart stage is the transition stage where cotyledons that to develop and elongate, rapid cell division occur.
Answer:
The osmotic pressure is 7.63 atm
Explanation:
We apply the osmotic pressure formula to solve this problem:
π = M . R . T . i
CaCl₂ → Ca²⁺ + 2Cl⁻ (i = 3)
The i refers to the Van't Hoff factor which refers to the amount of ions dissolved.
T is the Absolute T°, for this case 310K
R is the universal constant gase → 0.082 L.atm/mol.K
M is the molarity → 0.1 mol/L
We replace the values → π = 0.1 mol/L . 0.082 L.atm/mol.K . 310K . 3
π = 7.63 atm
These are properties of water that occur due to the hydrogen bonding in water: cohesion, adhesion, surface tension, high polarity, high specific heat capacity and high heat of vapourization.
These properties makes water to be a unique universal solvent.
