Crocodiles and alligators are both reptiles from the same order of animals, named Crocodylia. There are however a number of important differences which set these apex predators apart *Crocodiles have a longer, more V-shaped head then alligators.
*The fourth tooth of a crocodile sticks out when its mouth is closed.
*Crocodiles are better adapted to living in seawater.
*Crocodiles are more aggressive than alligators.
*Crocodiles tend to have a lighter appearance than alligators.
*Crocodiles in the wild are found all over the world while alligators are only found in the US and China.
<span>The trilobites seen in this image was once found widespread in the ocean. Something Changed To Limit and finally abolish their success. What do scientists use this example as proof of ? The answers are A. life changes over time and B. Vesitigial organisms once had a function in ancient times.The trilobites first appeared in the Cambrian period and though they entered a decline int the Devonian period, some of them survived until Permian time or for a period of 270 million years. They were divided into 3 segments and were early examples of arthropods. They tended to live on or near the bottom of the oceans and were scavengers in part and as well as living on the ocean floor some swam and fed on plankton. </span>
Adult stem cells
very important for replacing lost or damaged specialized cells.
The question is incomplete as it does not have the options which are:
A. bioremediation
B. mutualism
C. quorum sensing
D. quorum settling
E. mass-settling
Answer:
C. quorum sensing
Explanation:
Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria. The quorum sensing process depends on the number of bacterial cells or the density of the cells.
When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene. In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.
Answer:
B. monitoring the transverse diffusion of human proteins within a mouse cell membrane
Explanation:
fluid mosaic model of membrane is considered to be as that structure of membrane in which protein layer is embedded between the two layers of lipids.
monitoring the transverse diffusion of human proteins within a mouse cell membrane did not verify the fluid mosaic model of membranes.
