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.
Answer:
The correct answer is d. Vertebral column.
Explanation:
The vertebral column (also called the spine or backbone), is the main component of the axial skeleton and supports the upper body. It is made up of numerous bones, called vertebrae. The vertebrae have different shapes depending on where they are in the column, according to their function. In the embryo, the spine has 33 vertebrae, distributed in 5 categories or regions: 7 in the cervical region (neck), 12 in the dorsal region, 5 in the lumbar region (lower back), 5 in the region of the sacrum (basal part of the column), and 4 in the coccygeal region (the end of the column).
