The preferred dating technique for obtaining a numerical age of an archaeological sample of charcoal is Radiometric dating, a technique used in estimating the absolute (numerical) age of geological materials such as rocks, minerals or organic matter, which is achieved from radioactive isotopes; which are based on the isotope decay series with constant rates of radioactive decay.

The patients skin laceration healed nicely leaving a cicatrix, which is a scar.
A cicatrix is the scar of a healed wound - when you have a deep wound, and it gets stitched/heals on its own, after a while, that wound is going to transform into a cicatrix, which is just a fancy medical term for a scar.

g when hydrogen is present and the citric acid cycle is active, the ph of the mitochondrial matrix is
11111nata11111 [884]

Answer:

The pH remains constant

Explanation:

The pH value of Mitochondrial matrix = 7.8 while the pH of the intermembrane space of the mitochondria = 7.0–7.4

The presence of the hydrogen atoms makes the mitochondrial matrix acidic and hence reduced the pH value but the pH of inner and outer matrix is maintained equal to each other thus as the H+ ion increases, the base concentration increases thereby pushing H+ to the inter membrane space and hence producing ATP.

A researcher is trying to design an experiment to measure the amount of energy a person uses during different activities. He pro
Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.
