Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.
The abnormal gene must have been located on the Y chromosome which is responsible for baby boys hence all his sons had the abnormal condition while none of his daughters had the condition.
Genes are the units of inheritance located on the chromosomes. Since the genes are located on the chromosomes, the chromosome involves determines what traits are transmitted.
For the porcupine man, the abnormal gene must have been located on the Y chromosome which is responsible for baby boys hence all his sons had the abnormal condition while none of his daughters had the condition.

Answer:
THE DOMINANT GENE CAME FROM THE FATHER TO ONLY THE SONS THE RECCESIVE GENE WENT TO HIS DAUGHTERS

Explanation:
b. All primates rely more on vision and less on their sense of smell.
c. Primates tend to have large brains in relation to their body size
d. Primates usually give birth to one offspring at a time.
Answer:
b. All primates rely more on vision and less on their sense of smell.
Explanation:
Primates make up a group of vertebrate animals and include apes (monkeys), lemurs and humans. All these beings have many similarities to each other, for example, all primates usually have five digits on each hand and foot, primates tend to have large brains in relation to body size and the larger the smarter brain the primate is, primates usually give birth one baby at a time. Not all primates rely more on sight and less on smell; humans tend to rely on sight more than on smell, but most other primates have more developed than humans, so the smell is more important to them.

Answer:
Using microscopy methods such as fluorescence microscopy and polymerase chain reaction (PCR).
Explanation:
A bacterium that is viable but non-culturable refers to those bacteria that are in a very low metabolic state (dormant state) that don’t grow but is alive. Methods based on culture will not be able to detect a viable but non-culturable bacteria, because these bacteria will not grow and in few cases if the bacterium could be cultured, it only grows in very specific conditions. The most common methods used to check for the presence of bacteria that are viable but non-culturable is the fluorescence microscopy. The disadvantage of this technology is that don’t discriminate between live and dead cells, it only detects its presence. Another common technology is a polymerase chain reaction (PCR), that detects DNA, but this technique also doesn’t discriminate between living or dead cells. But usually is combined with stains to detect a damaged of the membrane, this damage refers to nonviable bacteria.
Energy will take the path from sun to stomach as sun's energy to chemical energy followed by thermal and mechanical energy.
Explanation:
The energy of the sun is in the from of chemical energy which is the ultimate basis of life on earth . The process of photosynthesis occurs to form a chemical compound named glucose. The food ingested is in polymer complex forms as protein, carbohydrate, fats etc which is broken into monomers for absorption in intestine and stomach.
The dietary compound has energy stored in their bonds as chemical energy.
So, from sun human consume chemical energy which is stored in food.
The energy even if consumed by eating meat is also chemical energy which is stored as potential energy.
The breakdown of food or chemical energy into monomers leads to release of thermal energy or heat to maintain optimum body temperature.
Chemical energy also gets converted to mechanical energy which allows functioning of vital organs and movement of body.
