Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Explanation:
Youngest to oldest would be: 3, 4, 1, 5, 2. Since it's from the bottom, the ones furthest from the bottom would be the youngest at the top. The oldest fossils would be closest to the bottom.
Answer:
Hotspot
Explanation:
Volcanoes can form in three different places: a convergent boundary, a divergent boundary, or a hot spot.
-At a convergent plate boundary, two plates collide and form a subduction zone. In the subduction zone, the denser, heavier plate goes below the more buoyant plate. The plate that goes under is subjected to immense heat and pressure and melts to form magma. This magma is less dense than the surrounding solid rock and rises to the surface through cracks in the plates to form a volcano.
- Volcanoes will form along divergent plate boundaries. A divergent boundary is when the plates move apart from each other. When the plates part, magma from under either plate rises and forms a volcano.
-A hotspot is the third place a volcano can form. This particular type is the least common. Hot spots are when thermal plumes from deep in the Earth rises. This heat, combined with the lower pressure at the bottom of the lithosphere, causes magma to form. The magma, as we discussed, is less dense than the surrounding solid crust and rises to the surface through cracks and channels and then erupts at the surface to form a volcano.
The introduction of a carbon-carbon double bond would cause a overall structure of the molecule to bend.
Carbon-carbon bonds are the type of bonds seen in hydrocarbon compounds which consists of two carbon atoms that has covalent bonds between them.
Covalent bonding occurs between atoms that share the electrons in their outermost shell to achieve an octet shape like the noble gases.
When there is an introduction of a carbon-carbon double bond, it leads to the bending of the overall linear structure.
This bend that is caused by the double bond is often referred to as "cis" and leads to a change in some physical properties of the molecule such as :
Therefore, the introduction of a carbon-carbon double bond would cause a overall structure of the molecule to bend.
