Answer:
A.Bases have a pH lower than 7.
Explanation:
pH, is the degree of acidity or alkalinity of a substance. pH uses a range of numbers from 0 - 14 to indicate the level of how acidic or basic a substance is. Generally, acids are substances that release H+ (hydrogen ions) when dissociated in water while bases are substances that release the OH- (hydroxyl ion) when dissociated.
In the pH scale, below 7 indicates ACIDITY with the lower (<) the value, the higher the acidity while greater (>) than 7 indicates ALKALINITY or BASICITY. Hence, according to this question, it is not to TRUE that "Bases have a pH lower than 7".
Answer:
Rabbits would survive because there's 1 less predator preying on them, therefore they will reproduce more rabbits and rabbits will overpopulate. And the same thing will happen with the mice, therefore the owls will have less competition over food and their population will grow.
Answer:
D
Explanation:
<em>The correct option would be therapeutic cloning.</em>
First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.
Artificial clonings are of different types, namely:
- Reproductive cloning
- Gene cloning
- Therapeutic cloning
<u>Reproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.</u>
Correct option: D
Answer:
I = 2.1 A
Explanation:
This is physics, but I will answer here either way.
First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:
V = R * I (1)
This is the Ohm's law. From here we can solve for I and:
I = V/R (2)
Now, we just need to replace the data and solve for the current:
I = 12.6 / 6
<h2>
I = 2.1 A</h2>
Hope this helps
