Note about the question:
Statements are missing, and I failed to find the complete question. So here I give you some details about the theory that will help you to indetify the correct statement.
Answer and Explanation:
The endosymbiotic theory essentially states that some organelles of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytosed but not digested by another cell. On the contrary, these bacteria were able to adapt to their host in such a way that the two cells established a dependent relationship with each other.
It is speculated that chloroplasts derivate from cyanobacteria and that mitochondria derivate from rickettsias.
Cells would be beneficiated from this new bond, at the point that they could not survive by themselves anymore.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest that they once were a free cell. For example,
Both organelles present their genetic material. This DNI is independent of the cell´s DNA, is bi-catenary and circular, identical to the bacterial DNA, and very different from the one of the eukaryotic cells. These organelles do not divide by mitosis. Instead, they do it by binary fission and are capable of synthesizing their ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacteria membrane, while the external membrane looks like the eukaryotic one. In fact, in this internal membrane are placed the energy centers, exactly as it occurs in bacterias membrane. Finally, the sizes of the organelles are similar to the size of some procaryotes.What adaptations are common for animals in hot and cold climates? Name at least two for both hot and cold climates.
Answer:
Explanation:
1. hot- camels live in hot deserts where its extremely hot and sandy therefore they have long eyelashes to protect their eyes just in case of sand storms
2. cold- penguins live in very cold climates so they have both black and white fur white so they can disguise in the snow from predators and black so they can absorb heat from the sun when they get extremely cold
3. hot -thick fur on the top of the body for shade, and thin fur elsewhere to allow easy heat loss. a large surface area to volume ratio - to maximise heat loss. the ability to go for a long time without water - they lose very little water through urination and perspiration. the ability to tolerate body temperatures up to 42°C

Explanation:
in what structures are diploid cells produced? how does this occur
Answer:
Early in the development of the embryo, specialized diploid cells, called germ cells , are produced within the gonads (such as the testes and ovaries). Germ cells are capable of mitosis to perpetuate the germ cell line and meiosis to produce haploid gametes.
The “Rule of 10” states that as little as ________ % of the energy at any trophic level is transferred to the next trophic level.
If I am a higher trophic level organism, this means that I need to eat MORE / LESS (circle one) food in order to fulfill my energy needs.
The majority of the energy is lost as ________________ through the completion of metabolic processes.
Answer:
1) "Rule of 10" states that as little as 10% of energy is transferred
2) Higher trophic level organisms need to eat MORE food, as energy is lost between trophic levels
3) The majority of the energy is lost as heat

Explanation:
A community wants to build an energy source to replace its coal power plant. The planners want it to be safe, renewable, and have a minimal impact on the environment.
Answer:
Solar energy can be used
Explanation:
Solar energy can be regarded as a radiant light and heat, it is an energy that is gotten from the Sun which is been trapped with the help of
range of ever-evolving technologies. This technologies could be photovoltaics as well as solar heating, and solar thermal energy. Solar energy is gotten from the sun and is been converted to "thermal energy" or "electrical energy". It's one of most abundant source of renewable energy with minimal impact on the environment. It is a very safe form of energy since it doesn't release CO2 or carbon monoxide to the atmosphere like coal power plant

Explain how endospores have allowed some bacteria, like tetanus, to be a successful species.
Answer:
Endospores allow Clostridium tetani (causative agent of tetanus) to survive harsh conditions in the environment. Because tetanus is an obligate anaerobe, oxygen is a harmful environmental factor. Endospores also allow the bacteria to resist desiccation (drying) and high temperatures.
The bacteria can be dormant as endospores until they are in favorable conditions. At this point, they will germinate into vegetative cells where they will be able to reproduce until conditions become unfavorable and they form endospores again.
Hope this helped!

Answer: spore open and bacteria goes in your pore making them zits
Explanation:
The spore form allows bacteria to exist under conditions not conducive to its life. It allows the bacteria to exist until the enviromental conditions favor its vegatative form when it can reproduce. Without the ability to form spores the bacteria would simply die out.
