<span>An electric current is running through the gel in the electrophoresis with positive pole on the bottom. So, only negatively charged particles can migrate through the gel in the electrophoresis. </span>Since DNA is negatively charged, it migrates toward the positive pole of the gel. This characteristic enables DNA to move through the gel.
The organelle inside the cell that eliminates waste is the lysosome. It contains chemicals that help digest food and worn-out cell parts. <span>When nutrients enter the cell, lysosomes release digestive enzymes to break down the nutrients. If the cell isn't getting enough food, lysosomes will digest other organelles so that the cell does not starve. Lysosomes eliminate worn-out organelles from the cell via the process of autophagy.</span>

Answer:
Nitrogen and phosphorus are among the elements considered most limiting to plant growth and productivity because they are often present in small quantities locally or are present in a form that cannot be used by the plant.
Explanation:
Declining krill populations will have catastrophic consequences for ecosystem homeostasis and it will increase the levels of phytoplankton.
<h3>What is ecosystem homeostasis?</h3>
The term ecosystem homeostasis makes reference to the state of equilibrium between different species in an ecosystem.
Krill are fundamental primary consumers in aquatic environments and they eat autotrophic phytoplankton.
In conclusion, declining krill populations will have catastrophic consequences for ecosystem homeostasis and it will increase the levels of phytoplankton.
