<span>An ecosystem is made up of animals, plants and bacteria as well as the physical and chemical environment they live in. The living parts of an ecosystem are called biotic factors while the environmental factors that they interact with are called abiotic factors.</span>
How do rivers become larger as they travel across land?
Tributaries combine, adding water to rivers.
A tributary is a stream that flows into a larger river. Small streams from around an area combine together to form a bigger tributary that eventually falls into rivers. This adds water to the main river, finally leading this river water out into an ocean.
Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum is part of the endomembrane system inside almost all eukaryotic cells.
The membrane is continuous with the nuclear membrane. The endoplasmic reticulum is very important for modifying proteins and transporting them in vesicles to the Golgi body for further processing and transport to their final destinations.
The endoplasmic reticulum can be rough (have ribosomes attached) or smooth (lack ribosomes).

I am almost positive you messed up a squeeze, so see how it is in the 4? Well that may mean it's 4, then the 5 is measured by the smaller line going before the 6.
Answer:
This quesiton is unclear
Explanation:
The body has negtive feedback loops that either vasoconstrict (preserving heat by lessening the surface area of blood vessels so they are exposed to less cold and release less heat) and vasodilation, where blood vessels are expanded and have higher surface areas so the body hopes to lose more heat to cool down.
If this is purely body language (like going into a fetal position when its cold: to lessen the surface area exposed to the cold temperature and lose less heat, imagine an ice cube vs. a long thin tube of ice with equal volume, the cube will last longer. Similarly our bodies would spread out to release more heat (unless there was sun) this is to expose the most surface area, allowing our body to release the most heat. Note: this is pretty insignificant change, and in extreme temperatures will likely not help, but it does contribute.
