A covenant bond is formed when electrons move from one element to another.
In plants, a new cell wall is fashioned between the new daughter cells
Animal cell membranes constricts to pinch the parent cell into the daughter cells
Answer:
60 dollars!
Explanation:
So, 12 oranges cost $36 dollars.
Now, we can solve this by finding the value for only <u>one</u> orange, then multiplying that by 20 to get our answer!
So, the value of one orange is $36 / 12 = $3. One orange is worth $3 dollars.
So, 20 oranges will be worth 20 * 3 = $60 dollars!
Answer: Option (a) is the correct answer.
Explanation:
Ionic salts are defined as the salts which tend to contain ionic bonds as there occurs transfer of electrons between its combining atoms.
So, when an ionic salt melts or it is dissolved in water then it will dissociate into its respective ions and as electricity is the flow of electrons or ions. Hence, this salt is then able to conduct electricity.
As covalent compounds are insoluble in water so, they do no dissociate into ions. Hence, they do not conduct electricity.
Similarly, metallic and network solids do not dissociate into ions either when melted or dissolved in water. Therefore, they also do not conduct electricity.
Thus, we can conclude that when a white crystalline salt conducts electricity when it is melted and when it dissolves in water then this bond is of ionic type.
Answer : The radioisotope which has longest half-life and can be best to be used in powering planet and space exploration vehicle and travel farther will be Plutonium - 239 as it has the half life of 24065 years. Which in comparison to other radioisotopes is longest.
Hence, Plutonium - 239 can be the best suitable radioisotope for powering the planet and space exploration vehicle to travel farther.
