Answer:
Statement that correctly states the evolutionary progression of hominids is that hominids first developed tools, then language and the brain increased in size.
Explanation:
The evolution of hominids occurred over a long period of time and included several steps in order for evolution to reach the Homo sapiens which is now known.
- <em>The first step in the evolution of hominids was standing -walking in an upright position on the lower limbs- which led to the release of the upper limbs.
</em>
- <em>The release of the upper limbs resulted in the use of the hands, which in turn led to the development of the first tools.
</em>
- <em>The development of language initially emerged with rudimentary sound-based communication, until it became a structured language.
</em>
- <em>During this process, the size of the brain -as well as the cranial capacity- increased as the hominid acquired new skills.
</em>
For this reason, the statement which best describes the evolution of hominids is that hominids first developed tools, then language and the brain increased in size.
Answer:
Option B, Sleep cycles in which REM sleep alternates with slow-wave NREM sleep.
Explanation:
The pattern of sleep is cyclical consisting of rapid eye movement (REM) pattern phase repeating itself after every ninety minutes. Within the gap of two REM phase, intermittent non rapid eye movement (NREM) pattern occurs. This type of sleep pattern is very usual in all mammals be it human or animals. During the REM phase of sleep, the brain is stimulated for its development and also protein production increases.
While in NREM phase, some involuntary body movements such as eye twitching, body straightening etc occur.
Hence, option B is correct
The mineral substances that are normally found in the blood, such as sodium and potassium, are known as Electrolytes.
<h3>Who are electrolytes?</h3>
Electrolytes are minerals that carry an electrical charge when they are dissolved in a liquid such as blood. Blood electrolytes – sodium, potassium, chloride and bicarbonate – help regulate nerve and muscle function and maintain an acid-base balance.
Major Electrolytes are Sodium, potassium, calcium, phosphate and magnesium are the electrolytes involved in salt balance disorders. In addition, the concentration of chloride and bicarbonate is commonly measured.
