Symbiotic association means one of the organisms, called endosymbiont, is present inside the cells of its host. The most typical examples are endosymbiosis theory of mitochondria and chloroplasts which, according to some theories, are cellular organelles of bacterial origin.
But these theories are still discussed because there are in fact arguments that support endosymbiosis theory and also arguments that disapprove it.
Here are the answer for the exercise explaining the endosymbiosis
A ==> oxygen-using procaryote (before being a mitochondrion)
B ==> mitochondrion
C ==> Nucleus
D ==> endoplasmic reticulum
E ==> Host cell: ancestor of all eucaryotes
F ==> photosynthetic procaryote (before being a chloroplast)
G ==> chloroplast
H ==> Host cell: Ancestor for photosynthetic eucaryotes
Answer:
its A
Explanation:
An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). Autotrophs do not need a living source of carbon or energy and are the producers in a food chain, such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs or other heterotrophs). Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and as stored chemical fuel. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. hope this helps :D
Answer:
D. As temperature increases, so does pressure.
Explanation:
As the temperature increases, the average kinetic energy increases, making the gas particles hit the walls of the container more (therefore increasing pressure). Hopefully this helps! Good luck :)
