Answer: Option B

Explanation:

The gastric juices helps in the digestion of the food but the pH of the these juices can affect the inner lining of the stomach if there would have no mucus secretion from the epithelial cells.

The low pH would have been destroyed the lining of stomach and this can result in the causing ulcer. To prevent this the walls of the stomach has epithelial cells that secretes sticky secretion known as mucus.

What do catalytic converters do?
schepotkina [342]

Answer:

a catalytic converter is device made up from metals like metals like palladium and rhodium to reduce the toxic gases emitted in the environment

Explanation:

Catalytic converter is an exhaust emission controlling device. It was made to reduce pollutants in air. Almost every automobile has a catalytic converter. It is present to completely remove the fuel that was not combusted and other toxic/dangerous compounds before they are let out in the environment.

If the catalytic converters are not used then the harmful compounds are released in the air and thus increasing air pollution and also decreasing the air quality for breathing in the surrounding environment.

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probabi
Ray Of Light [21]

Answer:

0%

Explanation:

This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state.

A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:

TT- T and T

Tt- T and t

Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced.

TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.

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.

Which respiratory disease in which sufferers are often called "pink puffers," is characterized by enlarged alveoli, lung inflamm
vitfil [10]
The correct answer is emphysema.
This respiratory disease occurs when alveoli get enlarged, and thus cause chronic lung inflammation and later on lung fibrosis as well. This person then finds it extremely hard to breathe properly, as airways tend to collapse during expiration.
