Leaf need water and minerals and root helps to take it from soil and passes it through stem.
stem also holds leaf in place.
hope this helps
When cells do not
respond to the signals that normally regulate cell division, cancer results. Cancer cells altered cell division in the
presence of signals that normally inhibit cell growth, with this; they no
longer require special signals to induce cell growth and division. The consequence
of the abnormalities of these cells could lead to mutations in protein-encoding
genes that regulate cell division.
<span>Moreover, they
also inhibit the growth of nearby cells that allow the cancer cells to spread
and invade other tissues. The uncontrollable division form masses of cells
called tumors that can impaired nearby tissues. If these cells stay in their
original site, they are considered benign, if they become invasive, they are
considered malignant which means that cancer cells metastasize, sending tumor
cells to distant locations in the body where new tumors may form.</span>
Answer:
Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak
Answer:
In which image will adenine (A) be the next nucleotide to be added to the primer?
T, CG, GC, CG, A
**In the example above, DNA pol III would add an adenine nucleotide to the 3' end of the primer, where the template strand has thymine as the next available base. You can tell which end is the 3' end by the presence of a hydroxyl (-OH) group.
The structure of DNA polymerase III is such that it can only add new nucleotides to the 3' end of a primer or growing DNA strand (as shown here). This is because the phosphate group at the 5' end of the new strand and the 3' -OH group on the nucleoside triphosphate will not both fit in the active site of the polymerase.
