4. what example does kraves give for how personal dna machines can save lives? explain.
5. do you think that personal dna machines would or hinder our criminal justice system and the work of forensic scientists? why? explain

If you still need it here you go!

Explanation:

3. Scientists use it to detect and address diseases, create medicines, modify foods, to assess whether or not our food is safe to eat, it can also be used to determine if someone is innocent of guilty based on DNA evidence.

4. You can get results to see if theres a disease faster, so you have more time to find out how to treat the person. For example, a Profesor traveled to Africa during the ebola breakout, he realized the doctors there didn’t have the tools to detect and fight diseases, results had to take weeks to come back, and that wasn’t enough time for the patients and families who are suffering.

5. This is more of a "in your opinion" question. But, I thought they can help scientists get the results much quicker.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
