Answer;
Mitochondria and chloroplasts contain their own DNA.
Explanation;
-Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell.
-From the Endosymbiotic theory, even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.
Answer is: active transport.
In active transport<span> because energy is required to move the sodium and potassium ions against the concentration gradient. There is two type of active transport:
1) </span>Primary active transport directly
uses metabolic energy (adenosine triphosphate- ATP) to transport molecules
across a membrane.
2) In secondary active transport (coupled
transport) there is no direct coupling of ATP, energy derived from
the pumping of protons across a cell membrane.
Some possible solutions to control the spreading are Invasive Species :
- Get your fishing and hiking gear clean.
- Never move the firewood.
- Whenever possible, catch fish with local bait.
- Join the removal effort as a volunteer.
- Before moving to a new body of water, clean your boat.
- When choosing plants for your garden, consult with your neighborhood nursery.
<h3>What is meant by invasive species?</h3>
Any non-native species that significantly alters or disrupts the ecosystems it colonizes is referred to as an invasive species, also known as an introduced species, alien species, or exotic species. Such species may migrate naturally to new areas, but they are frequently brought in by the activities of other species.
Rabbits, foxes, cats, pigs, untrained goats, rodents on islands, red imported fire ants, Psittacine beak and feather disease, and chytrid fungus are a few examples of invasive species key threatening processes that cover individual threats.
