Answer: DNA ( deoxyribonucleic acid) is a chemical substance which is called as the genetic material of all living organisms. It is packaged into the threadlike structure, called as chromosomes. This means that chromosomes are composed of a chemical substance, which is called as DNA.
Whereas, genes are the segment of DNA ( which code for specific proteins) present on the chromosomes. Thus, they carry information for specific trait of the individual ( like eye color)
In summary, their composition and functions are similar as all play a significant role in passing information from one generation to next and thus, determine the characteristics of the offspring.
<span>Distance has a huge influence on a planet's average surface temperature. So the answer is A. </span><span>Planet B is expected to be cooler than Planet A.</span>
When<span> the number </span>of<span> electrons </span>does<span> not equal the number </span>of protons<span>, the </span>atom<span> is</span>ionized<span>. (The </span>atom<span> is then called an ion). ... </span>If<span> your </span>atom is too ionized<span>, it </span>will<span> likely zip away from </span>you<span> and attach itself to a nearby </span>atom<span> or molecule. An </span>atom becomes radioactive when<span> its nucleus contains </span>too<span> many or </span>too<span> few </span>neutrons<span>.</span>
Crocodiles and birds I think
<span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them.
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
Sorry its so long but that the answer i think >:) ur welcome
