Explanation:

The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.

Answer:

Option D is the correct answer.

Explanation:

The speed of sound refers to the distance travelled per unit time by a sound wave as it moves. At 68º F its speed in air is about 343 meters per second, or 767 miles per hour or a kilometer in 2.9 seconds. There are two big factors to be considered: first one is temperature and the material the sound is traveling through, so the last option is the right answer.

Answer - Yes! of course. For better outlook you want to be in a city like Miami, FL U.S or someone populated cause that is where your able to find patients in need of recover.

Using the help of the semi conservative replication of DNA, What is the role of a single strand of DNA ?
Vera_Pavlovna [14]

Answer:

In the semi-conservative method of DNA replication, each of the strands of the double helix acts as a template for replication.

Explanation:

Semi-conservative DNA Replication:

  • Semi-conservative DNA replication produces two daughter helices from the original parent helix. One strand of the daughter helix is form the original template while the other is newly synthesized.
  • This means that one strand will have the base sequence identical to the parent, while the other will be complementary to the template.
  • This model was experimentally confirmed by an experiment conducted in 1958 by Meselson and Stahl. They used radioactive isotope of nitrogen i.e. N-14 or N-15. DNA molecules made with N-15 were allowed to replicate in the presence of N-14.
  • After first replication, DNA molecules contained both N-15 and N-14 isotopes, disproving the conservative model that stated that the new helices are completely identical to the template.
  • The second replication yielded only N-14 which disproved the dispersive model that the new helices are a combination of both the template and new strands.

Amino acids are usually taken up into animal cells using a coupled transport system in the plasma membrane. Clearly stated in th
exis [7]

Answer:

It requires energy

Explanation:

In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.
