The outer skeleton provides protection due to the fact that invertebrates do not have backbones
Answer:
3 peaks
Explanation:
Topographic map is used to show different landforms using different symbols. There are two important elements of landforms that include elevation and slope. It uses contour lines to portray different features of lands on the map such as slope and elevation.
<em>According to topographic maps, more close are the counter lines, more elevation are in the landforms. </em>
Peak is the pointed top of mountains. In this topographic maps peaks or elevation is shown in the form of irregular spherical shape. There are 4 elevations in the map but only 3 shows the peak according to counter line formation and the fourth elevation will not have peak on the top.
Hence, the given topographic map has only 3 peaks in the landform.
The correct answer is: 100x.
The calculation of total magnification of the microscope includes multiplying the magnification of the lenses together, So, to calculate the total magnification take the power of the objective (10X) and multiply by the power of the eyepiece, ocular lens (10X).
The hindbrain consists of the medulla, the pons, and the cerebellum.
<h3>The hindbrain</h3>
The hindbrain is the portion of the brain that is otherwise known as the rhombencephalon. It is the part of the brain that is located towards the lower back.
The hindbrain consists of 3 main parts:
- The medulla oblongata
- The pons
- The cerebellum
Each component has specific functions they perform. The medulla oblongata is located at the extreme end where the brain connects with the spinal cord. It controls activities such as heartbeat, blood pressure, and respiration.
The pons of the hindbrain work hand in hand with the medullar oblongata for effective breathing. In addition, it is the part of the brain that controls the circadian rhythm of the body.
The cerebellum helps the body to maintain postural balance and adjustments when necessary.
