The process of development of a seed into a new plant is also called the germination process.while the pollination is the process of seed dispersion.
Germination occur in favourable conditions including environmental condition like how deep seed is planted, water availability,sunlight and temperature
D. all of the above
as they are all, evergreen, short and contain flammable oils
Answer:
parathyroidoma
Explanation:
The condition where the parathyroid hormone is produces excessively is termed as Hyperparathyroidism. This condition arises when the balance between the calcium and phosphorus gets disturbed. The calcium and phosphorus balance is affected in following two cases –
a) When the parathyroid gland is not working properly due to its own problem usually termed as hyperparathyroidism or more specifically primary hyperparathyroidism
b) When the parathyroid gland is not working properly due to any other disease in the body affecting the functioning of parathyroid. It is termed as secondary hyperparathyroidism
Answer:
The correct option is B. Activation energy
Explanation:
The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.
For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.
The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
Answer:
Last electron level
Explanation:
Valance electrons are always in the outside level!
