Transmission electron microscopes (TEM) is one of the two main types of electron microscopes, the other type is scanning electron microscope.
Transmission electron microscopes are best viewing thin specimens (tissue sections, molecules, etc) . TEM is mainly used for the following things: to image the interior of cells , to image the structure of protein molecules and the organization of molecules in viruses.
Answer: small brain, small teeth, at least some bipedal ability
members of the genus Australopithecus are indicative of small brain, small teeth, at least some bipedal ability.
The genus name Australopithecus <span>means “southern ape,” based on the first fossils found in South Africa which was characterized by a combination of humanlike and apelike traits. They were similar to modern humans in that they can walk on two legs (bipedal) but, they had small brains like apes. Their canine teeth were smaller and their cheek teeth were larger than those of modern humans.</span>
The are both eukaryotic cells
Answer:
<em>The correct options are :</em>
<em>A) The biodiversity will decrease because there are fewer species on the newly formed island.
</em>
<em>D) The species on the island will likely have lower genetic diversity than the species on the mainland.</em>
Explanation:
When a larger population is broken down and a smaller population is formed, the genetic diversity in the smaller population will be lower as it has fewer species. As a result, options for genetic variations will be lesser. Hence, the landmass which drifted away will have lower biodiversity than the mainland. There will be more number of species on the mainland hence the genetic diversity will be more there.
The process that Darwin described as "descent with modification" is the process of evolution.
"Descent with modification" is one of the fundamental ideas behind Darwin's theory of evolution. According to Darwin, the characteristics of an organism are inherited. Offspring with inherited characteristics which allows them to compete best with the limited resources in the environment will survive. Organisms will pass the traits providing an advantage to survive and reproduce to the next generations. Over time and generations, the traits providing reproductive advantage will become common among the polpulation. This will lead to change in populations over generations in a process called the "descent with modification".
