Answer and Explanation:
An acid has a pH that is less than 7. A base has a pH that is greater than 7. Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.
Situation 1: Base
Situation 2: Acid
Situation 3: Acid
Situation 4: Base
Situation 5: Acid
Situation 6: Base
A. Water directly out of the tap has a pH of 7.2. When you add carbon dioxide (blow into the water), you get a pH of 5.1. This means that the addition of carbon dioxide makes water more acidic.
B. The most basic solution will have the highest pH. This means that it will be water with bleach added to it.
C. The most acidic solution will have the lowest pH. This means that it will be water with instant coffee.
Answer:Biological structures are able to adapt their growth to external mechanical stimuli and impacts. For example, when plants are under external loads, such as wind force and self-weight, the overloaded zones are reinforced by local growth acceleration and the unloaded zones stop growing or even shrink. Such phenomena are recorded in the annual rings of trees. Through his observation of the stems of spruce, K. Metzger, a German forester and author, realized that the final goal of the adaptive growth exhibited by biological structures over time is to achieve uniform stress distribution within them. He published his discovery in 1893.12 A team of scientists at Karlsruhe Research Centre adopted Metzger's observations and developed them to one single design rule: the axiom of uniform stress. The methods derived from this rule are simple and brutally successful like nature itself. An excellent account of the uniform-stress axiom and the optimization methods derived from it is given by Claus Mattheck in his book ‘Design in Nature’.13 The present study utilizes one of these methods, stress-induced material transformation (SMT), to optimize the cavity shape of dental restorations.

The answer is true and not false
Ok so if the circle is the female than her thing would be C. If the square is the female it would be D! I hope this helps!
Answer:
Human microbiome
Explanation:
The microbiota that aggregates in the human tissues including placenta, skin, lungs, saliva, and seminal fluid is the human microbiome. The microbiota can be virus, bacteria, fungi and protists.
The microbiome present in the human gut helps in digestion and also provides immunity. Microbiomes can be healthy or unhealthy and an imbalance of both can lead to weight gain, high cholesterol and blood sugar. These are the ecological communities that includes symbiotic, commensal and pathogenic microorganisms.
