Explanation:
Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.
Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.
I have attached a diagram that shows the greenhouse effect. It might help to visualise this.

What are the phases of a twitch contraction?
- A single contraction is called a twitch. A muscle twitch has a latent period, a contraction phase, and a relaxation phase.
- A graded muscle response allows variation in muscle tension.
What is a latent period ?
The amount of time that passes between an action potential being generated in a muscle cell and the beginning of muscular contraction.
What is a muscle twitch?
- The fundamental reaction of a motor unit to a single stimulus is a muscle twitch. Muscle Twitch in three different states .
- Excitation of the muscle fiber takes place during the latent phase, and calcium ions are released from the sarcoplasmic reticulum into the cell's cytoplasm.
What happens during latent period of muscle twitch?
- A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase.
- The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle.

Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
