If they keep killing sharks, then the shark population will become extinct, I'm not sure if anyone wants to put a stop to it at all. About 100 million sharks are killed by humans every year.

Why is it is more important for DNA replication to be exact than for transcription or translation to be exact? (1 point)
algol [13]

Answer:

an error in dna replication would affect many generations of cells

Explanation:

because DNA replication contains essentially all the genetic materials that will be needed in transcription and translation processes. And DNA replication is first step to ensure correct protein synthesis and others as well. But translation and transcription are both important to be exact, actually as incorrect transcription or translation could lead to useless proteins or etc.

Esperanza is having a prenatal test to remove a small sample of the placenta for genetic testing. Identify the test that her doc
lara31 [8.8K]

The correct answer is chorionic villus sampling.  

Chorionic villus sampling is a kind of prenatal diagnosis to find the genetic or chromosomal disorders in the fetus. The transcervical method is done by administering a thin plastic tube via the cervix and vagina to reach the placenta. A small sample of chorionic villus tissue is then withdrawn.  

The chorionic villi are the projections of placental tissue, which share the genetic makeup of the baby. The chorionic villus sampling is generally done between the weeks 10 and 13 of pregnancy.

10 things we need clean water for? ​
laila [671]

Answer:

Take shorter showers.  A four-minute shower uses approximately 20 to 40 gallons of water.

2. Turn off the tap.  When washing your hands, turn off the water while lathering up. Turning off the water while you brush your teeth helps to save over 150 gallons of water a month. Turn off the shower while you wash your hair and you’ll save another 150 gallons a month!

3. Fill ‘er up. Always run a full load of laundry, but if you can’t, make sure you adjust the settings to the proper load size. If you’re in the market for a new washing machine, look into a front-loading model– most are energy and water-efficient, using just over 20 gallons a load. Most top-loading machines, unless they are energy-efficient, use 40 gallons per load.

4. Fix it but don’t forget it.  Leaks can add up to 5 gallons a day! Check for leaks on all your hoses, faucets and connectors– fix ‘em but make sure to keep checking for leaks throughout your house.

5. There’s no such thing as “waste water”.  When you give your pet fresh water, don’t throw the water down the drain, water your plants with it instead. While you’re waiting for your water to heat up in the shower or washing your fruit and veggies, collect the water and use it again elsewhere!

Outside

6. Re-route rainwater.  A rain barrel watering system is awesome, but you can also install gutters and downspouts, directing the rainwater to your trees and shrubs. This saves water and reduces runoff.

7. Use a broom to sweep your driveway and sidewalks.  Hosing down your driveway and sidewalks is wasteful and contributes to poor ocean water quality. Use a broom and dustpan instead.

8. Follow best lawn practices.  Drought-resistant landscaping is best but if you do have a lawn, let it go dormant in winter. You only have to water every three to four weeks, less if it rains (or snows). When mowing, raise your lawn mower to 1.5 to 2.0 inches. Tall grass shades roots and holds in more moisture than short grass.

9. Water wisely.  Water plants and grass at night or in the early morning to minimize evaporation. Water deeply and less frequently to encourage deep root growth and drought tolerance. Use a kitchen timer or your smart phone timer so you don’t overwater.

10. Plant an Ocean Friendly Garden.  In many homes, more than half of the water goes to maintain thirsty plants and grass. Plants adapted to your region’s climate and soil require a lot less water and maintenance, and could save you up to half of your household water use!
