Answer:
B Tundra.
Explanation:
Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.
Explanation:
Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area . Regions of similar climate and dominant plant types are called biomes.
Climate is the major factor affecting the number and diversity of plants that can grow in a terrestrial biome. Climate determines the average temperature and precipitation, the length of the growing season, and the quality of the soil, including levels of soil nutrients.
The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.
Answer:
The correct answer is E. Answer choices a, b, and c.
Explanation:
There can be many causes for a gram standard culture to appear red like if we use decolorizer for a long time then even the gram-positive cells present in the culture will lose their dye and become decolorized. Then they appear red after counterstaining with safranin.
If a gram-positive culture is older than 24 hours they can appear red because after 24 hours because the peptidoglycan starts degenerating and fails to persist crystal violet it their walls.
Iodine makes complex with crystal violet which is retained by peptidoglycan present in gram-positive cell wall. So when we forgot to add iodine crystal violet will not be retained and cells will appear pink.
Thus, the correct answer is E. Answer choices a, b, and c.
