hard parts are most likely to be preserved
Answer:
A. It decreases the activation energy needed to start the reaction
Explanation:
Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place
When this occurs the minimum amount of energy of reaction to activate or stimulate the the atoms and molecules of the substrate to undergo chemical reaction is lowered.This energy of reaction is celled activation energy.
Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation energy.
<h2>Answer </h2>
DNA are found in the cells of all living organisms
<u>Explanation</u>
DNA is a complex molecule consisting of many components which are passed from parent organisms to their offsprings during the process of reproduction. The DNA contains instruction needed for an organism to develop survive and reproduce. DNA is deoxyribonucleic acid and is contained in your body's cells. From microscopic view they are double, large cable of particles termed as nucleotides. This show the cell what proteins to produce in the living organism. Hence, all living things have DNA within their cells.
Answer is letter B: prophase
Endocrine Signaling
Signals from distant cells are called endocrine signals; they originate from endocrine cells. In the body, many endocrine cells are located in endocrine glands, such as the thyroid gland, the hypothalamus, and the pituitary gland.
