Q:</span><span>Proteins have a variety of functions within a living cell. Describe at least three of the possible functions of proteins, and explain how proteins can be</span><span>
A:Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.</span>

Answer:
Radiometric dating methods
Explanation:
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.
The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.
Answer:
Photosynthesis takes place inside plant cells in chloroplasts.
Chlorophyll is a green pigment,present in all green plants which is responsible for the absorption of light to provide energy for photosynthesis.
400 mA, 70 ms is the following exposure factors will produce the greatest receptor exposure.
C: 400 mA, 70 ms
<u>Explanation:</u>
As SID builds, the introduction rate diminishes and receptor presentation diminishes. SID and the mAs required to keep up the introduction to the IR have a straightforwardly corresponding relationship (as the SID builds, the mAs required to keep up presentation to the IR increments by a corresponding sum).
An expanded SID likewise decreases amplification (size twisting). The most extreme SID ought to be utilized when conceivable to limit amplification. Infrequently, however, the SID can be purposefully diminished for amplification. SID influences size yet not shape twisting.
