Answer:
The electron microscope
Explanation:
<em>Fimbriae are very tiny appendages of about 3 to 10 nm in diameter found on the surface of most Gram-negative and some Gram-positive bacterial cells. They are mostly utilized as a structure to adhere to one another, to other organisms, or any other surfaces.</em>
Fimbriae generally contain adhesins, a virulence factor that facilitates adhesion to surfaces and <u>due to their tiny size, they can only be viewed using the electron microscope</u> - the scanning electron microscope to be precise.
Answer: phosphates absorbed by plant roots
Explanation:
The inorganic phosphate ions are available in the rocks which are distributed into the soil by the withering process. The aquatic plants absorb the phosphate ions through their roots. The plants are consumed by the animals. The inorganic phosphate is converted by the plants and animals into organic form incorporated in the DNA.
Answer: Only a little colder.
Explanation: It started out much hotter, so it will stop cooling down before it reaches the same temperature as the room.
Answer:
photoperiodism
Explanation:
this determines the length and height of the plants when plants adjust to growth.Plants also use the phytochrome system to adjust growth according to the seasons. Photoperiodism is a biological response to the timing and duration of dark and light periods. Since unfiltered sunlight is rich in red light, but deficient in far-red light, at dawn, all the phytochrome molecules in a leaf convert to the active Pfr form and remain in that form until sunset. Since Pfr reverts to Pr during darkness, there will be no Pfr remaining at sunrise if the night is long (winter) and some Pfr remaining if the night is short (summer). The amount of Pfr present stimulates flowering, setting of winter buds, and vegetative growth according to the seasons.
