The first, most anterior pharyngeal arch gives rise to the oral jaw. The second arch becomes the hyoid and jaw support. In fish, the other posterior arches contribute to the branchial skeleton, which support the gills; in tetrapods the anterior arches develop into components of the ear, tonsils, and thymus.

What are the characteristics that make a seed a living or non-living thing ?
Answer:
Seeds are living things as they contain an embryo that is capable of germinating to produce a new plant under optimum temperature, humidity and availability of water. If seeds were not alive, they would not have been able to germinate, give rise to seedlings and develop into mature plants.

what do electrons in the same shell have in common
Answer:It predicts and lists all chemical elements in the universe. What do electrons in the same shell have in common? They all have the same amount of energy. ... They cannot be broken apart without losing their chemical properties.
Explanation:I took a quiz on it
Electrons in the same shell, also known as the same energy level or principal quantum number, have energy, shielding effect, chemical behavior, etc. in common.
Electrons in the same shell have approximately the same energy level. The energy of an electron is determined by its distance from the nucleus, and electrons in the same shell are at a similar average distance from the nucleus.
Electrons in the same shell shield each other from the positive charge of the nucleus. This shielding effect reduces the attraction between the positively charged nucleus and the negatively charged electrons in the outer shells.
Electrons in the same shell participate in similar chemical reactions and exhibit similar chemical behavior.
Electrons in the same shell occupy orbitals with similar shapes. Each shell contains one or more subshells, which consist of specific orbitals that can accommodate electrons.
Thus, these are the properties of electrons in same shell.

What happens when a mechanical wave travels through a medium?Analyzing Mechanical Waves and Energy. As a mechanical wave travels through a medium, its amplitude can decrease due to the wave being spread across more matter and energy being transformed into other forms. Select all statements that describe why a wave's amplitude might decrease as it moves through a medium.
Answer:
The amplitude of a wave can be decreased because of the second law of thermodynamics and/or the differences of the propagation medium.
Explanation:
The wave is formed by a transference of kinetic energy between particles in a fluid state. Different medium has different inertia. When a shock wave travels through the water it has a different velocity when the same energy is dissipated as a wave in the air. The lower the inertia of the medium the bigger is the amplitude and vice-versa.
Another way that wave's amplitude might decrease as it moves through a medium is because of energy losses accordingly to the second law of thermodynamics. That means, when a part of a closed system interacts with another part, the energy tends to divide evenly, until the system reaches a thermodynamic balance.

what makes mining possible in continental crust? 2-3sentences science
Answer:
Due to softer materials.
Explanation:
Lighter materials of the crust made mining possible in continental crust because the materials present in the upper part of the crust are softer and lighter as compared to lower part. When the earth surface cools down, the lighter materials moves upward while denser materials remains in the center so that's why mining can be done in the continental crust due to its softer nature.

The sky on Earth is blue because blue light is scattered through the atmosphere as the other colors of light pass through undisturbed. Which nebulae have something similar going on?
Answer:
Yes
Explanation:
Reflection nebulae mostly appear to have a blue colour. This is because particles in the nebula scatter (or reflect) blue light more efficiently than they scatter red light. The same effect is responsible for our sky being blue, not red, during the daytime.
