Since the radiation has no mass .It is Gamma radiation.
Step by Step Explanation:
Characteristics of Gamma radiation are as follows:
- Gamma radiations are chargeless.
- It is Electromagnetic wave having a very short wavelength.
- It is not effected by the electric or magnetic field.
- It has velocity equal to light in vaccum .
- It has a very high intensity and can penetrate long distances.
- It has a very low ionizing power. i.e. it does not ionize the medium in whic it travels.
Gamma radiation has proved itself to be very useful in radioactive treatment of cancer due to its high penetrating power.
Both of those two independent methods of investigation resulted in the same pattern which means it is significant.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc.
It is used to organize living organisms into specific categories.
<h3>
Answer:</h3>
The generation of local currents.
<h3>
Explanation:</h3>
An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.
2 molecules of amino acids joined to form a peptide bond and the resulting molecule would be dipeptide.
Explanation:
When two amino acid molecules combine they form peptide bonds and in the process release one water molecule and a dipeptide is formed. This process is called dehydration synthesis. Many amino acid molecules eventually connect by peptide bonds resulting in a protein molecule.
The answer is D. Telegraph, telephone, cordless phone , mobile
