D an animal or plant getting a new "ability" is an example of evolution like this plant can climb now
<span>The myelin sheath allows nerve impulses to propagate very quickly along a nerve's axon to transport the signal between nerve cells. The myelin coating allows the chain reaction of impulses to jump certain distances instead of waiting for the chemical changes to happen at all points on the axon.</span>
Answer:
C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
Explanation:
A common symptom that would alert the nurse that a preterm infant is developing respiratory distress syndrome is expiratory grunting.
An audible grunt (forced expiratory sound) in a newborn is a crucial indicator of pulmonary disease and reveals a small lung volume or functional residual capacity (FRC). The baby's FRC rises when breathing against a partially closed glottis, maintaining the alveoli's patent state.
In an effort to maintain FRC and avoid alveolar atelectasis, the glottis suddenly closes on expiration, causing a grunting sound. Achieving and maintaining physiologic FRC is crucial in the management of respiratory illnesses with poor compliance, such as RDS or TTN, because lung compliance is worse at very low or very high FRC.
