Alternating phosphate and sugar residues

The structure of DNA consists of three main molecules-

1. Nucleotides

2. Sugar

3. Phosphate

Now, nucleotides are present on the inner side of the DNA strand, the sides or the backbone of DNA is made of the other two molecules, i.e. sugar and phosphate. The structure looks like the image shared below. One carbon atom of the sugar molecule is connected to nucleotide, and two carbons are connected to phosphates at two sides. This way a chain or the backbone of DNA is formed.

An action potential involves the transfer SODIUM and POTASSIUM ions across an axon's membrane.
During depolarization, when the ion channels open, they allow the influx of sodium ions into the cell, thus changing the electro-chemical gradient of the cell, in order to counter balance this, potassium ions will be allowed to flow out of the cell.<span />

What causes a sea and land breeze?
viktelen [127]

☁️ Answers ☁️

☁️ During the day, the sun heats up both the ocean surface and the land. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. ☁️

❤️

☁️ Land: The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind ☁️

☁️ Sea: A sea breeze is created when a low pressure forms over the coast. The sea has a greater heat capacity than land, meaning it requires more heat to change its temperature. Therefore, during the day, as the sun’s warm rays shine down on the earth, because of the difference in heat capacity, the land heats up faster than the sea. ☁️

Hope it helps.

Have a nice day noona!~  ̄▽ ̄❤️
