(OMG PLEASE HELP ASAP!!:c)What is the major function of proteins in cells? 1.They contain the instructions for the cell to carry out all the functions of life

2.They provide components of cell membranes and organelles and speed up chemical reactions

3.They provide energy and components of cell walls and cell membranes They provide energy and components of cell walls and cell membranes

4.They store energy and provide certain components of cell membranes

1. They contain the instructions for the cell to carry out all the functions of life.

Explanation:

Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
