Answer:
B. Early Eukaryotic cells engulfed mitochondria and chloroplasts
Explanation:
Mitochondria and Chloroplast are organelle that are found in cells of higher animals. Chloroplast are found almost exclusively in plants and mitochondria is found in animal cells. The function of these organelles are to produce energy to the cells, and by extension, the organism that they live in.
Unique features of these organelles show that they have their own DNA and divide and multiply on their own. This strongly suggest that they were once free living prokaryotes and were engulfed by larger cells and a symbiotic relationship began.
As time progressed, these prokaryotes did not require all of their genetic information and this was removed from their system. They kept essential genes and regulatory bodies separate that they needed for their maintenance and function that they provide.
A. can be used as an energy source by organisms.
DNA is made up of sugars and bases.
Fats are not glucose monomers. Carbohydrates are made up of glucose monomers.
The cell first needs to replicate DNA by using the previous DNA as template. Then the cell can get two sets of same DNA. When division, each set DNA will go to each cell so that a full set of DNA gets passed on to each daughter cell.
Answer:
It all comes from the sun
Explanation:
this is because without the sun plants wouldn't grow and without plants our meat sources can't eat and therefore nothing else can either.
Answer:
Explanation:
Based on the scenario being described it can be said that this would partly be explained by the biological reason that the amygdala, which is the seat of emotions such as anger—matures earlier than the prefrontal cortex in adolescents. Thus mostly explaining why Donna is first and foremost clouded by her emotions instead of logically reasoning through a situation.
