Please Help!!! Will mark brainlyest!!!
Lina20 [59]

Answer:

Explanation:

Both organelles, the mitochondria and chloroplasts (in photosynthetic organisms), are compartments that are believed to be of endosymbiotic origin.A compartment is a separate space within a larger whole. In relationship to the endomembrane system and the nucleus.organelles that aren’t part of the endomembrane system, such as mitochondria and chloroplasts.Cellular compartmentalization allows cells to optimize the efficiency of the processes that occur within organelles. But despite the advantages of compartmentalization, it’s not a universal feature of life. In fact, compartmentalization of cellular functions into membrane-bound organelles is limited to only one of life’s three major groups, or domains. That domain is the one that we belong to, the Eukarya. In addition to animals, eukarya includes plants, fungi, and other organisms with eukaryotic cells: cells that are relatively large, complex, and compartmentalized. And to see why that is, we need to look at how life has diverged over time.

(ii) Explain why the people were not protected from cholera immediately after receiving the
lara [203]

Answer:

It is safe to drink and use bottled water with unbroken seals, and canned or bottled carbonated beverages.

If bottled water is not available, use water that has been properly boiled, chlorinated, or filtered:

Boiling is the most effective way to make water safe. If boiling, bring your water to a complete boil for at least 1 minute.

If boiling is not possible, you can use a chlorine product (i.e., granules or product tablets) to make your water safe. To treat your water with chlorine granules or tablets, use one of the locally available treatment products and follow the instructions.

If a chlorine treatment product is not available, you can treat your water with household bleach. Visit CDC’s Making Water Safe in an Emergency page for specific instructions on how to treat your water with household bleach.

Always store your treated water in a clean, covered container.

Clean food preparation areas and kitchenware with soap and safe water and let them dry completely before reuse.

Piped water sources, drinks sold in cups or bags, and ice may not be safe. If you suspect your water may not be safe, boil or treat it with a chlorine product.

2. Wash your hands often with soap and safe water*

Before, during, and after preparing food for yourself or your family

After using the latrine or toilet

After cleaning your child’s bottom

Before and after caring for someone with cholera

Follow the five steps to washing hands the right way:

Wet your hands with clean water.

Apply soap to your hands and rub them together. Be sure to lather the back of your hands, between your fingers, and under your nails.

Scrub your hands for at least 20 seconds.

Rinse your hands well under clean water.

Allow your hands to air dry or dry them with a clean towel.

* If proper handwashing resources are not available, wash your hands using water that is as clean as possible (e.g. that’s not visibly cloudy) from a safe source (e.g., an improved source like a borehole or protected spring).

Traveling to an area with cholera?

The FDA approvedexternal icon a single-dose live oral cholera vaccine called Vaxchora®. Vaxchora is recommended to prevent infection in adults who are 18 – 64 years old and are traveling to an area of active cholera transmission with toxigenic Vibrio cholerae O1 (the bacteria strain that most commonly causes cholera). For more information, please visit the cholera vaccines page.

3. Use latrines or bury your poop; do not poop in any body of water

Use latrines or other sanitation systems, like chemical toilets, to dispose of poop.

Wash hands with soap and safe water after pooping.

Clean latrines and surfaces contaminated with poop using a solution of 1 part household bleach to 9 parts water.

What if I don’t have a latrine or chemical toilet?

Poop at least 30 meters (approximately 100 feet) away from any body of water and then bury your poop.

Dispose of plastic bags that contain poop by putting them in latrines or at collection points, if available. You can also bury them in the ground. Do not put plastic bags in chemical toilets.

Dig new latrines or temporary pit toilets at least a half-meter (approximately 1 ½ feet) deep and at least 30 meters (approximately 100 feet) away from any body of water.

4. Cook food well (especially seafood), keep it covered, and eat it hot. Peel fruits and vegetables*

Be sure to cook shellfish (like crabs and crayfish) until they are very hot all the way through.

*Avoid raw foods other than fruits and vegetables that you have peeled yourself.

5. Clean up safely in the kitchen and in places where the family bathes and washes clothes

Wash yourself, your children, diapers, and clothes, 30 meters (approximately 100 feet) away from drinking water sources.
