Answer:
They sleep on just one side of their brain at a time
Explanation:
Dolphins are different from fishes that can breathe underwater.
It is necessary for them to get to the surface of the water at intervals to breathe air.
While sleeping, dolphins allows one hemisphere of their brains fall asleep while the other half is fully conscious. This means that If the left brain is sleeping, the right eye stays open and if the right brain is sleeping, the left eye stays open.
This happens so they always know when it's time to surface and breathe and when to escape when there is trouble.
Answer: A
Explanation: Because Taq polymerase came from a thermophilic bacterium known as Thermus aquaticus found in Yellowstone National park, during PCR they should be kept at a specific temperature of 72C for maximum DNA strand replication and range of 75C-80C for optimum DNA strand replication.

Answer:
C
Explanation:
Gymnosperms generally refer to a group of terrestrial, seed-producing vascular plants whose means of reproduction is an exposed ovule known as a cone.
There are 6 divisions within the gymnosperms, including cycads, ginkgos, and pinus (conifers). Gymnosperms are generally non-flowering and produce needle-like leaves. Their species are usually woody or perennial shrubs/herbs
This is <u>unlike the angiosperms</u> that are usually classified into 2, including the eudicots and the monocots. The division is based on the number of cotyledons or seed leaves carried by the plants in the group during germination.
<em>The correction option here would, therefore, be C. </em>
The fluid in the cochlea moves in response to vibrations from the oval window. 25,000 nerve endings are set in motion as the fluid moves.
Mechanical vibrations of the stapes footplate at the oval window generate pressure waves in the perilymph of the cochlea's scala vestibuli. These waves travel around the cochlea's tip, through the helicotrema, and into the scala tympani before dissipating as they hit the round window. Sound-induced pressure changes in the cochlea travel down the fluid-filled tympanic and vestibular canals, which are filled with a fluid called perilymph. The membranous oval window functions similarly to a piston in a hydraulic system, pushing and pulling on the enclosed fluid.
