How does the body create a difference between atmospheric and intrapulmonary pressures to cause air flow to and from the lungs

Biology

Angelina_Jolie [31]3 years ago

Answer:

During inspiration, the diaphragm and external intercostal muscles contract, causing the rib cage to expand and move outward, and expanding the thoracic cavity and lung volume. This creates a lower pressure within the lung than that of the atmosphere, causing air to be drawn into the lungs.

Sloan [31]

A human fetus develops at the mother’s body temperature. At birth, most newborns experience a drop in temperature, and their bodies must quickly do something about it. What they do is the same thing a hibernating mammal does as it rouses itself from its winter "snooze." During hibernation, an animal’s body temperature is low. In order to move about and take care of itself once awake again, the animal that has been hibernating must raise its body temperature. (William k. Purves et al., life: the science of biology) The definition is the primary pattern of organization in this passage.

This passage is explaining the process of hibernation and its importance in the animal life cycle.

iVinArrow [24]

Answer:

Evolution

Explanation:

Evolution is the change in habits, hereditary and physical characteristics of a species over various generations in response to environmental conditions. Evolution lead to adaptation, the nature selection of the fittest and elimination of remaining.

Evolution may produce variety and diversity in response to mutation, genetic drift and other genetic variation. These changes may pass to offspring and may express them more in one group of population.

Evolution also explain the unity among organisms by explaining their shared characteristics. This refers to their common ancestors.

If a TRNA had a AGC anticodon it could attach a
Contact [7]

A transference RNA (tRNA) is an adapter molecule that decodes a codon messenger RNA (mRNA) during the synthesis of a polypeptide chain. These molecules (tRNAs) play a fundamental role during translation.

  • If a tRNA had an AGC anticodon it could attach a codon having the sequence UCG.

  • During translation, tRNAs act at specific sites in a ribosome to synthesize a polypeptide chain (i.e., a protein) from an mRNA sequence.

  • The anticodon of the tRNA binds by base complementary to a triplet of nucleotides or 'codon' in the messenger RNA (mRNA) during protein synthesis (i.e., translation).

  • According to the base complementarity rules, in RNA, Adenine always pairs with Uracile (Thymine in DNA), whereas Guanine always pairs with Cytosine.

Permitting the exchange of nutrients and gases between the blood and tissue cells is the primary function of ________.
zlopas [31]
Permitting the exchange of nutrients and gases between the blood and tissue cells is the primary function of capillaries. Capillaries are the smallest blood vessels , they are only one cell thick, and they act as sites of the transfer of oxygen and other nutrients from the bloodstream to the body tissues. Additionally, they also collect carbon dioxide, waste materials and fluids for return to the veins.
