Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.
Answer:
Descriptive investigations are not repeatable because they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.
Explanation:
Well there is not much to go off of, but I am very confident the answer would be studying fossil records,
Step 1: DNA replication begins at the origin of replication
Step 2: Helicase cuts hydrogen bonds and separates DNA in half
Step 3: Single strand binding proteins attach and keep the DNA molecules separated.
Step 4: The replication fork is formed with the leading and lagging strands
Step 5: In the leading strand RNA primase moves along nucleotides and coats with a RNA primer.
Step 6: DNA polymerase attaches post primase to DNA nucleotides and moves along towards the replication fork in 5 prime --- 3 prime direction. It adds nucleotides to the half DNA molecules
Step 7: Another type of polymerase replaces the primer with DNA nucleotides so all DNA is there
Step 8: Ligase stitches up the gaps.
Hope this helps!!!
If it does Rate, Thank, and MAKE ME BRAINLIEST. :ppp
