Answer:
The answer is solar.
Battery disposal is a disadvantage of SOLAR ENERGY.
Let me know if this helps!
An organisms metabolism doesn't quite invilve sleeping by the idea that metabolism is greatly enhance when one has a stimulus of generated cells (thanks to the assistance of hormonic means). Metabolism can be formulated better, however, metabolism does not really involve sleep.
The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.
The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.
When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.
Answer:
= 
Explanation:
Given that the woman’s maternal grandfather is color-blind, then it is possible that the woman is a carrier of color-blind allele.
Then probability that the woman is a carrier of color-blind allele is =
So if a carrier woman cross with a normal man
Let say the gene of the carrier woman is: 
and the normal man = 
so if we have a cross between
and
; we have:



we can see the offspring to be :
=normal unaffected female
= normal unaffected male
= carrier female for color-blind
= carrier male for color-bind
Then probability that of inheriting defective allele =
= 
Let's not forget that the probability that the woman is a carrier of color-blind allele is =
∴ the probability that the son is colorblind = 
= 
Depolarization is initiated when there is an influx of sodium inside the cell as opposed to repolarization, where potassium exits the cell (occurring after Na+ gates close). Remember that for every 3 Na+ in, there is 2 K+ out. This imbalance helps to stabilize the membrane.
