Answer:
The nucleus is found at the center of the cell.
Explanation:
Answer:
<em>A</em><em>.</em>
<em>The correct answer would be A. ratio of surface area to volume .The cells are mostly spherical in shape.The surface area of the sphere = 4πr²The volume of the sphere = (4πr³)/3Thus, the increase in size would increase the volume (r³) more as compared to the increase in surface area (r²).The ratio of surface area to volume would decrease due to which the diffusion rate would not be efficient enough to distribute the essential elements throughout the volume of the cell.</em>

The extinct ancient human Homo erectus is a species of firsts. It was the first of our relatives to have human-like body proportions, with shorter arms and longer legs relative to its torso.
<h3>What are Homo erectus?</h3>
Homo erectus, an extinct species of Pleistocene archaic human, first appeared about 2 million years ago. Several human species, including H. heidelbergensis and H. antecessor, seem to have diverged from H. erectus, with the former being largely accepted as the ancestor of Neanderthals, Denisovans, and modern humans. Among the first recognizable representatives of the genus Homo are its specimens. The first known ancestor of modern humans, H. erectus, had a continental range that stretched from the Iberian Peninsula to Java. H. floresiensis and possibly H. luzonensis may have its origins in Asian populations of Homo erectus. H. erectus soloensis, from Java, dates to a time period between 117,000 and 108,000 years ago.
