What are the gases on Makemake?
The thin atmosphere of Makemake is primarily composed of methane, with small amounts of nitrogen and possibly ethane. Methane is responsible for the dwarf planet's reddish-brown coloration due to the presence of tholins, complex organic molecules formed by ultraviolet radiation interacting with methane.
What forms the ozone layer protecting us from UV radiation?
The ozone layer is predominantly formed by the interaction of oxygen molecules with UV radiation in the stratosphere. Ultraviolet radiation breaks down oxygen molecules into individual oxygen atoms, which then bond with other oxygen molecules to form ozone (O3). This ozone layer helps to absorb and block a significant portion of the sun's harmful UV radiation from reaching the Earth's surface.
What process that uses gamma rays to eliminate harmful bacteria in meat and poultry?
Gamma rays have extremely high energies, and seeing as they are a form of ionizing radiation, they can cause cellular damage. When gamma rays are aimed at bacteria, in much the same as radiation harms humans, DNA damage occurs eventually resulting in the death of cells.
What are the some complex food molecules?
Starch (polysaccharide), proteins, and lipids are some complex food molecules.
Why was the formation of the ozone layer so important to the evolution of your earth?
The ozone layer blocks harmful ultraviolet radiation from the sun, which allowed life to thrive on Earth by protecting organisms from radiation damage. Without the ozone layer, high levels of UV radiation would make the surface uninhabitable for complex life forms.

What are the gases for ultraviolet radiation?
Exciplex lasers use a combination of a noble gas--argon, krypton, or xenon, with a reactive gas such as fluoride or chloride. Exciplex lasers are sometimes mistakenly referred to as "excimer" lasers, but "excited dimers" are two of the same molecule, rather than an "excited complex" of different molecules.

What role does energy play in the synthesis of complex molecules?
Energy plays a crucial role in the synthesis of complex molecules by providing the necessary power for chemical reactions to occur. These reactions require energy to break and form bonds between atoms, allowing for the creation of larger and more intricate molecules.
In anabolic reactions, how do biochemical reactions facilitate the synthesis of complex molecules within living organisms?
Biochemical reactions in anabolic processes help build complex molecules by combining simpler molecules together. This synthesis is driven by enzymes that catalyze the reactions, allowing the formation of larger molecules like proteins, carbohydrates, and lipids essential for the growth and maintenance of living organisms.
Why is radiation considered dangerous?
The high-energy particles of radiation can damage the complex molecules, such as proteins and DNA, that are important to life. This damage can prevent our cells from functioning and can outright kill them. In the long term, the damage to DNA can cause cancer.

Controls movement in and out of the nucleus?
The nuclear pore complex controls the movement of molecules in and out of the nucleus. It acts as a selective barrier, allowing only specific molecules to pass through the nuclear envelope. Signals on molecules regulate their transport through the nuclear pores.

The ozone layer blocks harmful ultraviolet radiation from the sun, which allowed life to thrive on Earth by protecting organisms from radiation damage. Without the ozone layer, high levels of UV radiation would make the surface uninhabitable for complex life forms.
How does radiation affect the structure of a stable molecule such as a molecule of water?
Radiation can involve gamma rays, X-Rays, alpha particles and beta partcles. In terms of molecules these are termed ionizing radiation but they both ionize and break bonds to produce radicals. Ionizing radiations effect on water is to produce hydrogen peroxide, hydrogen, oxygen, ozone, . The pathways are complex involving the breakdown of water molecules into positively charged radicals, such as H2O+, neutral radicals OH and H and solvated electrons. Chain reactions coupled with reionization of some of the "initial" products makes for a complex situation.
Why do enzymes break down smaller molecules quicker?
Enzymes break down smaller molecules quicker because they have active sites that specifically fit the smaller molecules, allowing for faster and more efficient reactions. Additionally, smaller molecules have less complex structures which make them easier for enzymes to process and catalyze.
