Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.
-T.B.
Solar Energy is best option of Coal power plant. It is safe as well as very minimal impact on environment.
Explanation:
Solar energy is one of the best ways to build an energy. It uses captured sunlight and create photovoltaic power or “concentrated solar power” for solar heating. The use of solar power is increasing day by day.
Now subway, buses, college, institute all use solar energy for their electricity consumption. Recently solar powered aircraft whose name is impulse2 is made. Because of zero emission of carbon dioxide government move towards this option.
Disadvantage: It is very costly and takes more space for installation
Answer:
Explanation:
porque una persona con dos alelos normales presentará un fenotipo normal, mientras que si las dos copias del gen son el alelo mutado que producen una enfermedad, el fenotipo expresará los síntomas característicos de esa enfermedad.
The answer is D. This ensures that the mule cannot have offsprings hence can't
continue its generation. Sterility of the mule is due to mismatch of homologous
chromosomes between the horse and the
donkey leaving an extra lone horse chromosome on the mule (since a horse has 64
chromosomes and a donkey has 62).
Answer:
Since sexual reproduction needs two individual animals for it to occur and genes from both, the offspring won’t be exactly like one or the other parent, so, on a larger scale, we will all be unique and diverse.
For further understanding, let’s think of an example. Your dad and mom are different than you are because you are created from both of their genes combined, creating a unique you. This promotes diversity for that we are all unique.
I hope this helps! :)
