Some isotopes, however, decay slowly, and several of these are used as geologic clocks. Dating rocks by these radioactive timekeepers is simple in theory, but the laboratory procedures are complex. <span>All methods rely on the fact that certain elements (particularly uranium and potassium) contain a number of different isotopes whose half-life is exactly known and therefore the relative concentrations of these isotopes within a rock or mineral can measure the age.</span>
I dont remember much of biology but i do remember my teacher saying something about phosphate backbone, i know its not much help. sorry!!
It is The multicellular part
Answer:
The main reason many people choose to avoid green action is that they think it will cost them more than their typical, environmentally harmful activities. Many times, it is true that environmental friendly products come with high up-front costs, but these costs almost always are made back over the lifetime of products. Many environmentally friendly products are far more efficient and cost-effective over their life-time than other, less clean options. For the most part, people are simply unaware of the economic benefits of going green. This lack of knowledge make consumers unwilling to make decisions that they perceive will cost them more money. No matter how dedicated to the environment a person is, if they believe it will lose them money, it is unlikely that they will ever do anything about it. While total spending on green products may be increasing in the United States, the market share remains dangerously low – typically making up only 3-5% of any given market.
<u>Answer:</u>
<em>ATP is used for immediate energy and short-term storage, while starch molecules are stable and can be stored for a long time.</em>
<u>Explanation:</u>
Starch and ATP can both be described as molecules that store energy. ATP is used for <em>immediate energy and short-term storage,</em> while starch molecules are stable and can be stored for a long time.
ATP is known as an <em>energy medium for a reason</em> does changes into energy. In this process starch does have to pass through various steps and series to convert into energy.
<em>Plants use starch for a very important purpose which is to store glucose.</em>
