What specific key factor starts the breathing process in a newborn infant?

Biology
1 answer:
kvv77 [185]3 years ago
4 0
Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.

Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.

Answer:

The correct answer is C  the extraction of high energy electrons remaining from glycolysis and citric acid cycle .

Electron transport chain(ETC)  occur in mitocondria and is the last process of aerobic respiration.ETC deals with the transfer of electron from the reducing equivalent such as NADH,FADH2 thereby oxidising them to their oxidized form NAD+,FAD.

            The liberated electron from these equivalents utilizes the proton motive force come from the transport of H+ ion cytosol to mitocondrial matrix and then result in the phosphorylation of ADP to form ATP along with H2O by the reduction O2.

What is the your groundbreaking idea for a razor or hair removal product that awakens your senses?​
Hatshy [7]

Answer:

hope it helps you

Explanation:

Traditionally, shaving and hair removal brands provide mainly functional benefits:   they get the job done, but they don’t deliver an enriching, self-care experience.  Their products aren’t going to uplift you or make you feel calm and relaxed.  Instead, they offer mundane experiences and boring designs and scents.

As a leading personal care brand, we are looking for razor and shave preparation ideas that will make shaving enjoyable, that are experiential, and that stimulate the senses (olfactory, tactile, vision, etc.).  We are looking for creative solutions that will appeal to those who love variety, who enjoy exploring new things, and who value enriching experiences.  Personal care should give us a chance to reground ourselves, awaken our senses, and feel better in our day-to-day.

We are interested in groundbreaking ideas for wet-shave devices (e.g. razors) and/or packaging that will awaken your senses without compromising the effectiveness or durability of the products.

Your idea could improve the sensory shaving experience at any level.  Primarily, we are looking for ideas that relate to razors, but we are also open to shave preparation (pre, during, post shaving) as well as packaging.  In proposing your idea(s), please consider the following:

Be creative!  Feel free to go beyond scents / olfactory experience.

Bring ideas for razors, shave preparation, pre-shaving and post-shaving.

Women should be the target demographic for your product idea.  Please be sure your idea has feminine appeal.

Your idea should be feasible for high-volume production (think about processing conditions and high speed manufacturing).

Your product idea should be able to survive in the typical “bathroom” / usage environment of a razor.  Think of the shower, where there is high humidity, exposure to chemicals from other products, etc.

Please include any references or background information related to your proposed material sources.  We want to understand what inspired your idea and review any relevant sources that support it!
