Answer: a. True
Explanation:
Reliability can be define as the consistency in the results or measure. A test is said to be reliable if the results obtained are repeated the same. For example, if a test is designed to observe and measure the trait, then each time the test is administered to the subjects, the results obtain will be approximately the same.
<h2>Muscular strength</h2>
Explanation:
Muscles that are elongated while activated (i.e., eccentric muscle action) are stronger and require less energy (per unit of force) than muscles that are shortening (i.e., concentric contraction) or that remain at a constant length (i.e., isometric contraction)
stronger muscle contraction includes:
- Potassium accumulate in the sarcoplasm
- Increase in muscle belly circumference
- Increased stimulus frequency
- Increased requirement
- Lesser proportion of motor neurons to muscle fibers
weaker muscle contraction includes:
- Begin contraction with muscle already 50% contracted
- Circular arrangement of muscle fascicles
- Lower sarcoplasm pH
You can work out the concentration of H+ ions (denoted as [H+]) easily on a calculator if you know the pH, which you do. The easiest way to work out [H+] is to do
. In your case, the maths here would be
, which gets you an answer of 1.58x
, or 0.000158. For 6.2 it would be
, which gives you 6.31x
, or 0.00000063. As you can see, the concentration of H+ ions is greater in pH 3.8.
To put it simply, the [H+] decreases the higher up the pH scale you go, and increases as you go lower, but now you know the maths to work it out for yourself too.

Answer:
Power was centralized with a goal of creating a modern economy.
Explanation:
The most important feature of the Meiji Restoration in Japan is the modernization of the country. In this period, various institutions are modernized such as banking system, system of justice in the courts and infrastructure i. e. railway roads are built across the country which is a main transportation in many countries and contribute in the economy of the country. Due to this modernization, Japan became a powerful country.
