<h3><u>Answer and explanation;</u></h3>
- DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
- <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
- <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
- Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
The greenhouse effect is the effect where carbon dioxide (usually from factory gas emissions, car exhaust gas, etc) gets sent into the Earth's atmosphere , however, instead of disappearing, it gets trapped under the atmosphere of the Earth and cause the temperature of the planet to rise. The temperatures rise since the radiation of the sun's rays gets trapped under the layer of carbon dioxide. This affects climate change since when the globe warms up, our earth begins to warm up too resulting in colder parts of the earth to rise in higher temperatures than usual.
This is true because electricity can be conducted throe metal not menials like plastic and rubber hope it helps
Answer:
High in the atmosphere, air pressure decreases. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
