In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though.
Just a little while after you started out as a fertilized egg, your cells started performing specific tasks, even started to look different because of that. Differentiation means that one cell performs a different function than another cell, depending on where it is in your body.
Not sure if this will help.
After a vigorous workout without consuming significant amounts of water, the specific gravity will have a higher concentration. A vigorous workout increases the breakdown of glucose, without enough water to flush it out it remains in the urine;meaning specific gravity will be high because of the of the high glucose content.
A, the power lines are what actually conducts (Or moves) the power.
hope this helps don't forget to make me the brainiest
Answer:
Comparative genomics of the three groups
Explanation:
The comparative genomics of the three groups was used to determine their evolutionary distinctiveness. Comparative genomics is a powerful tool used to study evolutionary changes among organisms, it helps to identify gene similarities and differences among organisms.
Bacteria and archaea (formerly called archaebacteria) were considered much more closely related, but DNA sequence analysis showed numerous differences between the two groups, and further proved that archaea was closely related to eukarya than bacteria.
However, in 1970, Dr. Carl Woese and other scientists in a bid to determine the distinction between the three groups made use of the nucletide sequence of the ribosomal RNA as an evolutionary time clock.
It is widely known that the rRNA sequences; is present in all organisms, functions differently in various organisms, is involved in protein synthesis, can be align between two organisms and can change gradually over a long period, hence this made it a good tool to determine evolutionary distinctiveness.
The pictured cell is in Metaphase as the chromosomes are lined up at the equator of the cell.
