Answer:
I think it's the second one
Answer:
Controlled burns are lit for a number of reasons. By ridding a forest of dead leaves, tree limbs, and other debris, a prescribed burn can help prevent a destructive wildfire. Controlled burns can also reduce insect populations and destroy invasive plants. In addition, fire can be rejuvenating for the plants.
Answer:
the fossils are examples of... mineralization
The fossils tell us that polar regions... formed a supercontinent that divided and slowly drifted to polar regions
Explanation:
Mineralization is a type of fossilization where rich-mineralized water fills the pores of the dead tissues for a long time. Subsequently, when this water is evaporated, the excess of minerals is deposited on the tissues, thereby mineralizing organic tissues.
Fossils enable us to understand more accurately past climatic conditions from regions where these fossils were found. For example, the discovery of plant fossils closely related to tropical species in polar regions suggests that these regions were once a part of a super landmass known as Pangea that divided and drifted a long time ago (millions of years ago).
The plant cell referred to in the question is attached to this answer.
The structure in the plant cell that represent the sites of ATP production from photosynthesis is the CHLOROPLAST; THAT IS OPTION B.
The photosynthesis reaction is divided into two stages, which are the light reaction and the dark reaction. The light reaction takes place in during the day in the presence of sunlight and it is during this period that ATP molecules are formed in the stroma of the chloroplast. During the dark reaction, the ATP produced during the light reaction together with NADPH are used as source of energy and reducing power respectively to manufacture carbohydrate from carbon dioxide.
