Answer:
Pressure is the force per unit area. This means that the pressure a solid object exerts on another solid surface is its weight in newtons divided by its area in square metres.Explanation:
The correct answer for the question that is being presented above is this one: "newts." The vertebrate that is ectothermic is a newt. A newt is a semiaquatic amphibian of the family Salamandridae, although not all aquatic salamanders are considered newts. Ectothermic is <span>an animal that is dependent on external sources of body heat.</span>
RELATIVE DATING is a way to estimate the order of geologic events by using rock layers, index fossils or other methods.
Relative dating is used by geologists to arrange geological events in sequential order. Relative dating usually use six principles to determine the relative age of any rock or fossil. The principles are: principle of superposition, principle of original horizontality, principle of lateral continuity, principle of cross cutting, principle of inclusions and principle of fossils succession.
Answer:

Answer:
Explanation:
A. The bacteria DNA will contain most of the radioactivity. The reason is that the DNA is made up of a sugar phosphate backbone which forms its structural framework. One grinding up the bacteria, the radioactive phosphate will likely react with the DNA.
B. In the second instance, the proteins will contain the radioactivity this is because, the DNA does not have any reaction with sulphur, on the other hand, proteins contain about 3 - 6% sulphur.
