<span>Answer is D. Nuclear power does not produce smoke or carbon dioxide.Nuclear power plants do not produce smoke or carbon dioxide while operating unlike fossil fueled power plants so it’s not contributing to the greenhouse effect but the process for refining uranium ore and creating reactor fuel requires a lot of energy.<span>

Answer:
d. on the plasma membrane
Explanation:
According to the endosymbiotic theory the origin of mitochondrion is from the prokaryotic organism: primitive host cell (future eukaryotic cell) engulfed prokaryotic cell (endosymbiont) that provided the functions that evolved into mitochondria. Both of them had benefits: the endosymbiont gained protection and some essential nutrients from the host, while host had the energy and oxygen source from the endosymbiont.
So, the plasma membrane of the endosymbiotic prokaryotic cell became the membrane of the mitochondrion.
Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemo-synthesis). Heterotrophs cannot synthesize their own food and rely on other organisms, both plants and animals for nutrition. hope this helps :)
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.
Answer:
The correct answer is option A. demonstrates that the E. coli cultures were viable.
Explanation:
In this lab experiment or culture, Plate I and plate III demonstrate, that E.coli bacteria can grow both in the presence and absence of plasmid DNA if ampicillin is not there.
So, which means that plasmid DNA is not required for the growth of E.coli in absence of ampicillin. The presence of growth in wild type (plate 1) and a plasmid containing bacteria (plate 3) in media without ampicillin shows that bacteria are viable in nature.
