The correct answer is B. Ordovician period
Explanation:
Plants are mainly multicellular organism that depends mainly on photosynthesis to obtain energy, this includes a wide variety of species such as grass, flowering plants, trees, shrubs, etc. Additionally, plants are considered as one f the two major divisions or kingdoms along with animals. In terms of history, it has been determined first land plants appear during the mid-Ordovician period around 470 million ago, although organisms that were the origin of land plants developed in water in previous periods, also by the Devonian period a wide variety of plants have emerged with features that are still part of plants nowadays. Therefore, plant life first appeared on land during the Ordovician period.
Answer:
low, under, beneath, down, or below normal
Unconformities occur when erosion wears away rock, or when rock deposits are never formed hope this helps :3
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.
