We know that animal populations exposed to higher concentrations of radioactive activity, often suffer deleterious genetic mutations. Thus, the answer would be <u>B.) a higher than average mutation rate.</u>
What are the 2 ways that cells know to stop dividing?<span>In cell division, the cell that is dividing is called the "parent" cell. The parent celldivides into two "daughter" cells. The process then repeats in what is called thecell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins.

Hello, i stated the basic information about Continental Drift below...hope this helps you .
So lets start off with Continental drift, <u>Continental Drift</u> describes one of the earliest ways geologists thought continents moved over time. Today, <u>the theory of continental drift has been replaced by the science of plate tectonics. The theory of continental drift is most associated with the scientist Alfred Wegener.</u> In the 20th century's, Wegener published a paper explaining in detail his theory that the <u>continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other</u>. He called this movement continental drift. <u>
Pangaea a landmass long ago when dinosaurs roamed the planet, was all of the countries today all placed in one whole landmass</u>, Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea. Therefore stating his theory of continental drift.
I have tried to explain simply the basic information to know about this topic , hope it helps you out. Let me know if you need any further information or detail of this topic. I also posted a picture to show you an example of the one, whole, huge landmass called Pangaea.
Answer:
True
Explanation:
An ecosystem includes all of the living things (plants, animals, and organisms) in a given area that interact with each other, as well as the non-living environments (weather, earth, sun, soil, climate, atmosphere) that surround the living things.
Answer;
-Species selection
-This trend toward species that have live birth in a particular environment is an example of species selection.
Explanation;
-Species selection is the process responsible for the proliferation of species that have lower extinction and higher speciation rates. Species selection is a reason why macroevolution and microevolution may be uncoupled.
-Suppose that larger-bodied species lineages tend to speciate more rapidly, and that the average rate of extinction is also less for larger species. Over time, this will result in a species trend, in which the clade becomes more speciose and each species on average larger.
