In the stomach, the enzyme pepsin has the function to break proteins into smaller units-polypeptides. Pepsin is synthesized and secreted in an inactive form- pepsinogen. Activation energy (the minimum amount of energy that is required to activate an enzyme) is achieved in the acidic medium (pH from 1 to 3). So, the activation of pepsin (conversion of pepsinogen to pepsin) is possible thanks to the cells in the stomach lining which produce hydrochloric acid (HCl), causing the stomach contents to have a low pH.

Antacids neutralize the acid made by the stomach, affecting the digestion.

Answer:

reduced release of gastric juices that provides activation energy for enzymes to carry out digestion of proteins.

Explanation:

Antacids are agents usually taken for reducing the acidity of stomach by neutralizing it . Due to this the pH of the stomach becomes very low. All enzymes which require a specific pH to digest enzyme are unable to perform in such environment as they are not able to activate themselves in lieu to reduced activation energy. Thus, the protein could not be digested effectively in an environment having antacid.

In humans, a type of blindness is due to a dominant allele; normal vision is the result of a recessive allele. Migraine headache
yan [13]

Answer:

Yes.

Probability of such child = 1/2 or 50%

Explanation:

According to the question, below are the genotypes and phenotypes possibilities:

aa = normal vision & no headache

Aa = normal vision & no headache

AA = blindness & headache

                                                                      Male                       Female

                                                                        Aa                            aa

Possible genotypes of progeny:            Aa        Aa           aa         aa

So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.

Mathematical expression is as under:

2/4 = 1/2 that means 50% progeny.

How did fossil<br> fuels form, and how<br> are they obtained<br> and used?
Usimov [2.4K]

Explanation:

Fossil fuels are important energy sources for our every day activities.

  Formation of fossil fuels

Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.

How are they obtained

First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.

For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.

For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.

How are they used

Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.

Natural gas is used as a domestic fuel for cooking and so also coal.

When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

Como aseguramos que en la mitosis la nueva célula es idéntica a la célula madre ?!!!
lozanna [386]

Answer:

The daughter cells are genetically identical because mitosis is a process that ensures the equal distribution of the replicated genetic material between these cells

Explanation:

During mitosis, the DNA is duplicated during the interphase (S-phase). Subsequently, the replicated chromosomes are arranged in the center of the parent cell (metaphase) to be finally separated and equally distributed between the daughter cells.
