Four; the upper atmosphere, the atmosphere, the mantle, and the core.
Answer:
Due to no transfer of resistance allele.
Explanation:
The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance
C It controls what is allowed to enter or leave the cell.
Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.
<u>Explanation:</u>
Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.
This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.
Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
