The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
Internal organs and tissues of an organism
The one of the marine creature named Mediterranean red coral lifespan is capable of covering nearly 500 years and challenge human age with full spirit, also observed that the patterns of sessile or immobile species like other corals, macroalgae, sponges and gorgonians have boon of long life under deep sea water.
One of the most basic reason behind their healthy life is the stability of environment which is favorable for deep-dwelling species, they get shielded from temperature changes and severe storms in such location. Pollution, poaching, contamination, human activities, etc are not that effective in deep sea, natural selection favors long lifespans in stable environments.
Answer: There are many sources of light, but the initial energy for all light sources comes from the sun. Light travels away from its source in straight lines through space as waves of energy. The waves we can detect with our eyes are called visible light. Patterns in the behavior of light are predictable because light moves in waves through space until it comes in contact with an object or material that changes its direction. Light can pass through or bounce off objects. Additionally, different materials can block or absorb light. If an object blocks light, a shadow of the object forms. If the intensity or direction of the light source changes, the appearance of an object’s shadow can change in size, shape, or darkness. Absorbing light energy can cause changes in matter. A common example includes the color of paper or fabric fading as the matter absorbs light over time. Vibrations cause sounds. We can hear when sound waves travel through the air to our ears and cause our eardrums to vibrate. Sound can also travel through other forms of matter, such as liquids and solids.
Explanation:
I believe the answer is; As stress levels from the anticipation of the race rise, Mary starts to sweat which causes change in the urinary system to conserve water. The autonomic nervous system causes the fight or flight response. When she is about to start the race, Mary feels anxious and is getting pumped up which causes his autonomic nervous system to active.
