Answer:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

Answer:
The tree will not survive due to the nature of the tundra
Explanation:
The tundra comes from a finnish word "tunturia" which means barren or treeless land. It is classified as a cold icy desert with permafrost on the ground. Unlike the tropical rain forest which is a wet climate group and is a forest of tall trees in a region of year round warmth, the tundra is cold and dry. The tundra soils are formed at high altitudes, they are usually frozen. Common plants in tundra are shrubs, herbs, lichens and grass and usually grow in groups and remain closer to the ground for prevention against cold winds. The cold nature of the tundra and its soil prevent the growth of trees because trees need to have deeper roots and they cannot grow on frozen ground.
Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.
Why do bacteria only grow at certain temperatures?
- The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
- Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
- An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.
