Answer:
The correct answer will be-<em> </em><em>Homo neanderthalensis</em>
Explanation:
The closest ancestor of modern humans which evolved in the Pleistocene age which was around 7 lakh to 3 lakh years is the <em>Homo neanderthalensis</em> or Neanderthals.
The Neanderthals became extinct around 12,000-10,000 years ago by competitive <em>Homo sapiens</em>.
The specimens of Neanderthals are collected from the central and Western Asia and parts of Europe and showed approximately the same cranial capacity which is around 1450-1500 cc.
Thus, <em>Homo neanderthalensis</em> is the correct answer.
Answer:
ionic bond
Explanation:
When two ions transfer electrons or bond together they make an ionic bond.
4 is correct. In a wide expanse of space, gravity drew dust and gas together to create the solar system. The sun formed first from the vast material.
The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.
<h3>What is muscle contraction?</h3>
It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.
<h3>Characteristics of muscle contraction</h3>
- In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.
- The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.
- To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.
Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.
