Answer:
DNA double strands are run in opposite direction
Explanation:
The DNA is a macromolecule and is made of the polynucleotide. In a DNA, Polynucleotides are arranged in two strands or helices. The two strands are joined together by hydrogen bonds. Each stand has two ends. One end is called 5’ (5 prime) and the end is known as 3' (3 prime). The two stands in a DNA run in antiparallel or in an opposite direction. It means at one end, one strand is 3' and the other is 5' and at the other end one strand is 5' and another strand is 3'.
When fossil fuel is burned it emits carbon dioxide into the air. And the ocean traps CO2, but it needs a good amount of fish to in order to contain. And 20% of Americas carbon dioxide emission is due to excessive farming, although there are other ways to avoid affecting global warming so i think this is the best answer. Deforestation as we all know takes away the balance between oxygen in the air and carbon dioxide so that wouldn't be you answer. I think your best bet is D since the articles i read are dated and there are more ways than one to farm.
Answer:
The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.
Explanation:
Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.
Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.
Matching coastlines and land formation created by glaciers are the two evidence that suggests that Africa, Antarctica, South America, India, and Australia formed Gondwana land 200 million years ago
Further Explanation:
Earth is being marked by almost five ice ages namely Huronian, late Paleozoic, Andean- Saharan, Cryogenian, and the latest one Quaternary Ice age. Well established earliest ice age rocks are called Huronian that is expected to be formed around 2 billion years ago during Proterozoic eon. Cryogenian has existed around 700 million years ago while the late Paleozoic age existed around 300 million years ago. Though the glacial period ended 8,000 years ago its effect is felt still today as its weight was so great that it led to the deformation of earth’s crust and mantle. During deglaciation sea level also rose and that resulted in the sudden shifting of the hydration system and coastline.
