<u>Answer:</u>

The correct answer option is B. Green wavelengths are the least used in photosynthesis.

<u>Explanation:</u>

Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.

From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.

Therefore, this reflection of green light makes the leaves to appear green.

Helen [10]

CAA - UGC - ACC - UUU is the transcripted RNA sequence basing on the GUU - ACG - UGG - AAA DNA sequence. This is because the transcription of G is C, and the equivalent of A or T is U, and the transcription of C is G. There is no T in a RNA sequence.

Answer:

Piccard and Walsh + Bathyscaphe Trieste
Forbes and Maury + Father of Oceanography
Developed in 1922 + Echo sounder
Locates Survivors at Sea + Sofar
Average of 30 miles wide + Continental shelf
The distance of open water over which wind flows + Fetch
Rescued at 5,000-foot depth + Alvin
Query buoy-mounted systems + satellite mounted sensors

Explanation:

Trieste was the name given to a Bathyscaphe which was designed by the Swiss and built by the Italians. A Bathyscaphe is a deep-sea vehicle or submersible that is able to propel its self and will require the presence of a crew cabin. Jacques Piccard and Don Walsh jointly achieved the goals of Project Nekton one of which was to get to the bottom of the challenger deep. The challenger deep is the deepest point in the earth's sea bed. Auguste Piccard is an Italian and the son of the man who designed the boat: August Piccard whilst Don Walsh is a US Navy Lieutenant.
Edward Forbes is considered the pioneer of oceanography and his area of specialty was the biological components of the ocean. Matthew Maury, on the other hand, is considered the father of oceanography because he focused on the physical components of the ocean such as currents, waves and temperature fluctuations.
Echo sounding is a special sonar that is used to calculate the exact depth of water. The device does this by transmitting sound waves into water the speed is calculated.
Sofar station was finished on the 4th of July, 1946. The full meaning of SOFAR is Sound Fixing And Ranging. It was designed or built to be able to locate stranded paramilitary such as Navy and Airforce survivors at sea.
The continental shelf is estimated by some to be approximately 30 miles wide. The continental shelf is a space beneath the ocean that speads out like a plateau and which holds a lot of biotic elements.
Waves are generated when wind flows over a water body in one direction for a protracted period. The Fetch is the oceanographic term for that area in the ocean where this phenomenon is prevalent.
Alvin is another name for DSV-2 - a deep ocean submersible owned by the United States which has made a deep dive at least 5000.
