What kind of sequence or structure would you classify this as
jeka57 [31]

Answer:

The correct answer will be option-A.

Explanation:

Inverted repeats are the sequence of the nucleotide in a nucleic acid which is identical but arranged in the opposite orientation. The inverted repeat may be separated by some sequence or they may lie adjacent to each other. They can be read the same from the backwards or forward direction.

In the given question since four bases when read from the forward direction is same as reading the sequence from the backward direction like CGAC can be read the same both backward and forward.

Thus, option-A is the correct answer.

The ecology question above says : A fast swimming strong body fish such as a swimming which is adapted to clear fast and strong
Dafna11 [192]

Correct question:  A fast swimming strong body fish such as a <u>salmon</u> which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file

Answer:

Source of a river zone

Explanation:

The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.

Rivers belong to lotic environments, characterized by constant moving water.

  • Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.
  • Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom.
  • Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish.
  • Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.

Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.
