Read the section titled “retaining water” and “acquiring water.” Explain how desert animals retain and acquire water in such a hot and dry environment
Which adaptation would be most beneficial of both the taiga and marine aquatic biomes
Answer:
Taiga includes a large species diversity of floura and fauna. This region is prone to extreme winter conditions. Both taiga and marine aquatic biome species adapt the adverse winter season. Plant species restrict their surface area in an attempt of protection against freezing, called hardening. Most of the animal species they hibernate so that they do not require food in harsh winters.
Answer:a thick layer of fat for insulation
Explanation:
Taiga has long cold winters so they need insulation. Marine aquatic animals like whales need the insulation when they are in cold water.
Identify the energy changes in each of the following examples
Pounding a fist on a table
When a fist pounds on a table, muscular energy is converted into kinetic energy, which is then transformed into sound and thermal energy upon impact. Similarly, when a hammer strikes a surface, its potential energy is converted to kinetic energy and then to sound and heat. Blowing through a rubber band converts chemical energy into mechanical and then into sound energy.
Explanation:When a person pounds a fist on a table, there is a conversion of energy from one form to another. Initially, the muscular energy in the person's arm is used to accelerate the fist downward. This energy is known as the kinetic energy of the fist. As the fist strikes the table, that kinetic energy is transformed into other forms of energy, primarily sound energy from the noise of the impact and thermal energy (heat) due to the friction and deformation caused by the contact between the fist and the table surface.
Another example of energy conversion occurs when a person strikes a hammer against a hard surface. The potential energy stored in the raised hammer is converted to kinetic energy as it falls. Upon impact, this kinetic energy is mostly transformed into sound and heat, similarly to the previous example.
The final example involves a person blowing through a slit in a stretched rubber band. Here, the chemical energy from the food the person ate is converted into mechanical energy of the moving air as they blow. The moving air causes the rubber band to vibrate, converting some of that mechanical energy into sound.
