The halogen elements are the six elements in Group 17 of the periodic table. Group 17 is the second column from the right in the periodic table and contains six elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (As), and tennessine (Ts). Astatine and tennessine are radioactive elements with very short half-lives and thus do not occur naturally.
Answer:
What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way
Explanation:
Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.
When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.
Answer:
TRUE
Explanation:
There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.
The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.
Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.
Thus, the above-given statement is true.
Answer:
The advantage of this is that there is a larger surface area exposed, more time available and shorter difference for exchange of oxygen.
Explanation:
It allows the individual in a populations to survive and have offspring with the desire trait needed to live while those without will die out
