What evidence in a slice of bread showed the presence of gas?

Biology
1 answer:
LenaWriter [7]3 years ago
6 0

Every slice of the bread, contains a number of blister like pores. These blister like pores suggests that the air or some gas might be present there. In case, the bread has no air, the surface of the bread must be smooth rather than rough.

The bread is formed by the fermentation of the sugar molecules present in the dough with the help of yeast. These blisters like structure on the bread is present due to the gas produced during fermentation.

Empirical evidence is obtained using our human senses, which statement
Inessa05 [86]

The statement “This type of evidence can be checked by others” best explains the importance of empirical evidence in science.

Explanation:

There are all kinds of evidence used in science, but empirical evidence is obtained as a result of <u>repeated experiments and observations</u>. This evidence is used to either support or argue against a scientific theory. Empirical evidence is the preferred evidence since this kind of evidence can be peer reviewed, i.e. reviewed by other scientists and/or researchers. In other words, the experiment can be redone, and the <u>evidence can be tested</u>.

yaroslaw [1]

Answer:

B. decreases salivation and increases blood pressure

Explanation:

The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.

The sympathetic nervous system  is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.

Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.

The control of salivary production by the sympathetic nervous system  leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.
