Answer:
Negative feedback.
Explanation:
It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.
In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.
Answer:
tundra, taiga, temperate grassland, rainforest
Explanation:
Tundra is known to be the coldest of all the biomes due to the high latitudes in which these areas are found. In this biome, the growth of the trees is limited by the low temperatures and the growing season is restricted to the summer season. The taiga is a type of biome composed of forest found in the subarctic areas, it is for that reason that taiga regions are also called boreal forests. Temperate grasslands are areas where grasses are dominant with very variable temperatures depending on the season (i.e. summer to winter seasons). In this biome, trees are relatively uncommon. Finally, the rainforest is the most diverse tree-rich biome where the high temperature and humidity conditions are optimal for life.
Answer:
A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell.
Explanation:
<em>When the concentration of electrolyte is greater inside the cell than its outside, water molecules move from the outside electrolyte into the cell leading to its expansion and turgidity. If the water movement continues, the cell may burst and release its contents in a process known as lysis.</em>
Hence, that a cell will shrink when the concentration of electrolytes is greater inside the cell than outside of the cell is false.
Sedimentary rock because type of rock that forms when sediments from a weathered rock were eroded and deposited in the ocean, where the compaction and cementation turned them into a new rock.
