Answer:
A. Distinction of the various rings of saturn.
Explanation:
The important discoveries of Hubble space telescope were on discovering the age of the universe, finding the depths and expanse of the universe, along with researching on the black holes and finding visible wavelength images. Finding planets in the inner solar system like Pluto, and an outer solar system like Exoplanets.
There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems:
Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy.
The number of cell phone users has increased rapidly. As of December 2014, there were more than 327.5 million cell phone subscribers in the United States, according to the Cellular Telecommunications and Internet Association. This is a nearly threefold increase from the 110 million users in 2000. Globally, the number of subscriptions is estimated by the International Telecommunications Union to be 5 billion.
Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models.
Sahelanthropus, Orrorin, Ardipithecus, Australopithecus, and Paranthropus are just a few of the genera that exhibit postcranial transformation and canine reduction throughout the first four million years or so of hominid evolution. There is a concurrent change in the hominid fossil record as the Pliocene epoch came to an end and the world climate was changing about 2.5 million years ago. Something novel arose in this setting, both physically and behaviorally, as it became cooler. The genus Homo originated from this.
The commencement of the transition from primordial, large-brained, stone tool-making, meat-eating apes that spread out across the globe to the species Homo's beginnings in Africa is marked by this change. Three species, Homo habilis, Homo rudolfensis, and Homo erectus, are considered to be the earliest members of the human genus. It is well known that H. habilis was the first species to produce stone tools and that it still possesses basic characteristics that connect it to australopiths. Aside from the fact that H. rudolfensis shared both time and space with other early Homo and had a larger brain and set of teeth than H. habilis, little is known about this species. Thanks to its extensive fossil record, we now have a better grasp of the paleobiology and evolution of the more complex H. erectus. With a physique designed for contemporary striding locomotion, H. erectus was the first fully committed, obligate biped to emerge outside of Africa. It was also the first member of the human ancestry to leave Africa. The first Homo species are the ones who tipped our evolutionary history's scales away from the more ape-like direction and toward the more human one.
