Plate tectonics, theory dealing with the dynamics of Earth’s outer shell—the lithosphere—that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans.


That is the theory of Plate Tectonics.

Sophie [7]

Answer:

a. eukaryotes

b. unicellular

c. autotrophs; heterotrophs

Explanation:

Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

kati45 [8]

Answer:

Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes.  No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?

genetic drift

Explanation:

Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above

Why is it important for geologists to use both relative and absolute ages to determine the age of rocks?
uysha [10]

Answer:

to help and determine the exact age of the rocks

Explanation:

The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.

Scientist could age the rock using two methods. They are :

Relative ages

Absolute ages

Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.

The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.

An energy-transferring compound in cells is a nucleotide known as
8090 [49]

Adenosine triphosphate (ATP) is a complex molecule which provides energy to the cells. This molecule is present in all the living organisms. The chemical energy which is obtained by the body by the breakdown of the food is captured by the ATP (Adenosine Triphosphate) molecules. This captured chemical energy is then transferred by it in order to fuel different body processes.

Hence, the answer is ATP (Adenosine Triphosphate).
