Answer:
chloroplasts work to convert light energy of the sun into sugars that can be used by cells. Its like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
Answer:
A) Times of major climate change
Explanation:
The geological time scale is based on major changes in Earth's climate history. This is because of the reason that climate governs the geological processes on Earth. In geology, we study the ages with the help of stratigraphical data where sediment deposition and the fossils it is hosting are the keys to understand the environmental conditions at that particular time. These conditions didn't change significantly unless the climate was changed. An example is the extinction of dinosaurs during K/T boundary event (mass extinction). The most likely reason is the hitting of a meteorite on Earth that changed the climate of Earth in a short period making it least favorable for many organisms to survive.
On the other hand, the occurrence of huge events cannot be used to establish a geological time scale because sometimes, the changes happen more slowly.
Similarly, shifts in the Earth orbits are cyclic however geological time scale doesn't reflect cyclic changes. The same climate can establish in different ages but these events are not used not as a criterion to establish a geological time scale.
In the end, the time span of humans on Earth is very small when compared with the overall geological time scale. Humans record exists from Pleistocene (2,580,000 to 11,700 years ago) to today whereas geological time scale starts in the Archean Eon (4.0 billion to 2.5 billion years ago).
The answer for this problem is 6. hope it works
The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
Symbolizing rebirth and new beginnings, the daffodil is virtually synonymous with spring. Though their botanic name is narcissus, daffodils are sometimes called jonquils, and in England, because of their long association with Lent, they're known as the "Lent Lily." A daffodil is a spring-flowering bulb, Narcissus is the name of a genus which includes flower bulbs like Jonquils, Paper whites and so forth. Narcissi (plural form of Narcissus) are easily grown from bulbs.
