Answer is that the cells exist inside the body
Explanation:
i went to science class 1 time in freshmen year
Answer:
Advanced forms of life existed on earth at least 3.55 billion years ago. In rocks of that age, fossilized imprints have been found of bacteria that look uncannily like cyanobacteria, the most highly evolved photosynthetic organisms present in the world today. Carbon deposits enriched in the lighter carbon-12 isotope over the heavier carbon-13 isotope-a sign of biological carbon assimilation-attest to an even older age. On the other hand, it is believed that our young planet, still in the throes of volcanic eruptions and battered by falling comets and asteroids, remained inhospitable to life for about half a billion years after its birth, together with the rest of the solar system, some 4.55 billion years ago. This leaves a window of perhaps 200-300 million years for the appearance of life on earth.
divine interventionThis duration was once considered too short for the emergence of something as complex as a living cell. Hence suggestions were made that germs of life may have come to earth from outer space with cometary dust or even, as proposed by Francis Crick of DNA double-helix fame, on a spaceship sent out by some distant civilization. No evidence in support of these proposals has yet been obtained. Meanwhile the reason for making them has largely disappeared. It is now generally agreed that if life arose spontaneously by natural processes-a necessary assumption if we wish to remain within the realm of science-it must have arisen fairly quickly, more in a matter of millennia or centuries, perhaps even less, than in millions of years. Even if life came from elsewhere, we would still have to account for its first development. Thus we might as well assume that life started on earth.
How this momentous event happened is still highly conjectural, though no longer purely speculative. The clues come from the earth, from outer space, from laboratory experiments, and, especially, from life itself. The history of life on earth is written in the cells and molecules of existing organisms. Thanks to the advances of cell biology, biochemistry and molecular biology, scientists are becoming increasingly adept at reading the text.
An important rule in this exercise is to reconstruct the earliest events in life's history without assuming they proceeded with the benefit of foresight. Every step must be accounted for in terms of antecedent and concomitant events. Each must stand on its own and cannot be viewed as a preparation for things to come. Any hint of teleology must be avoided.
I believe that ones sense of civic duty and apathy are attitudes that are usually acquired from ones parents. A sense of civic duty is influenced by deeply rooted personality traits. Parents play a vital role in determining the sense of civic duty and apathy, because they are responsible for the upbringing of a individual and teach the kids on how to relate with other people.
Unlike mitosis, meiosis of a single cell results in the formation of <span>four genetically unlike cells. The correct option among all the options that are given in the question is the fourth option or the last option or option "d". I hope that this is the answer that has actually come to your desired help.</span>
Both their own individual life experiences and the evolutionary history.
<h3>What about biological anthropologists?</h3>
- Since genes are the main cause of human diversity, they can look at genes.
- Since differences in health are the primary cause of most human diversity, they can research health.
- Understanding human adaptation to various settings, the causes of illness and early mortality, and how humans descended from other animals are all goals of biological anthropologists.
- They research people (alive and deceased), other primates including monkeys and apes, as well as human predecessors, to achieve this (fossils).
- The study of biological anthropology focuses on the variety and environmental adaptations of our closest living relatives, monkeys and humans, as well as their evolutionary history.
- The strong evolutionary perspective of biological anthropology is one of its key features.
