Answer:
857mL de la solución al 7%
Explanation:
Una solución de agua oxigenada (H₂O₂) al 7% contiene 7mL de peróxido de hidrógeno por cada 100mL de solución = 7mL H₂O₂ / 100mL Sln
Para preparar un litro = 1000mL de disolución al 6% de peróxido de hidrógeno se requieren:
1000mL Sln * (6mL H₂O₂ / 100mL Sln) = 60mL H₂O₂
Para obtener 60mL de H₂O₂ a partir de la solución al 6% se requieren:
60mL H₂O₂ * (100mL Sln / 7mL H₂O₂) =
<h3>857mL de la solución al 7%</h3>
Since the measurement is not changing, the answer is 100 mL. Hope this helps.
Hypersaline
Explanation:
Mono Lake is a land locked body of water with a salinity of about 40 parts per thousand.
A lake is natural body of water surrounded by water.
Salinity is the amount of salt concentration in water body.
A salinity value of about 40 parts per thousand is said to be hypersaline.
This is salty water with a lot dissolved NaCl in it. it takes several years of dissolution of salt for a water body to have high salinity

Explanation:
- An analogy can be defined as a cognitive process which typically involves comparing things having similar characteristics or features for the purpose of explanation or clarification.
- An observation can be defined as a process which typically involves carefully monitoring something for the purpose of understanding and clarity.
- An inference can be defined as a cognitive process which involves reaching a conclusion or forming an opinion based on sets of evidence or reasoning.
1. Mary discovered that the cell membrane of a bacteria acts like a fence because it keeps some things in and other things out: this is an analogy because there's a comparison between the cell of a bacteria and a fence.
2. Mary walked into her room where her little son was playing, found a broken window, and thought immediately that her son had broken it: this is an inference because she immediately thought her son broke it.
3. Mary noticed that her counter top was warm to the touch: this is an observation which was based on an evidence of touch.
4. Mary noticed that the side walk was wet and thought that it may have been that the sprinklers had been on recently: this is an inference because it was based on her thoughts.
5. Mary counted and recorded 20 heart beats in 10 seconds: this is an observation because she actually counted her heart beats.
6. The lecturer compared the human eye to a camera lens: this is an analogy because it was a comparison between a human eye and a camera lens.
