Answer:
about 5 billion years ago
Explanation:
Our solar system formed about 5 billion years a go from a dense cloud of interstellar gas and dust.
Answer:
What we eat matters. The food choices we make every day have a big effect on the environment. The good news is that even small changes in what we buy and eat can add up to real environmental benefits, including fewer toxic chemicals, reduced global warming emissions, and preservation of our ocean resources.
Explanation:
Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
Na+/K+ ATPase exists in two forms: Its phosphorylated form has a high affinity for K+ and low affinity for Na+. ATP hydrolysis and phosphorylation of the Na+/K+ pump favor the release of Na+ outside the cell and binding of K+ ions from the outside of the cell. Dephosphorylation of the pump increases its affinity for Na+ and reduces that for K+ ions resulting in the release of K+ ions inside the cells and binding to the Na+ from the cells.
The presence of ATP analog would not allow the pump to obtain its phosphorylated form. Therefore, Na+ ions would not be released outside the cells. This would increase the Na+ concentration inside the cell above the normal. Similarly, the pump would not be able to pick the K+ from the outside of the cell resulting in reduced cellular K+ concentration below the normal range.
Although the application of biotechnology has many potential advantages, it also has potential risks. These risks include increased resistance of insects and microorganisms, overproduction of new plants, and competition with natural organisms. Some individuals may not believe that the benefits of biotechnology outweigh the risks.
