Moon has very low gravity.,.. That's all gases escape from moon.. And it has no atmosphere.
Answer:
Breathing rate is most likely to increase if the blood level of carbon dioxide increase.
Explanation:
Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.
Answer:
D. A waxy coating on a plant
Explanation:
A cuticle can be described as a waxy covering which preserves or protects certain parts of plants like leaves, shoots etc. Lipid molecules which are saturated with waxes make up the cuticle. Cuticle majorly functions in stopping the evaporation of water from the cell's epidermal layers. All the species of plants possess this waxy coating of cuticle because it plays important role in stopping the loss of water from the cells.
Answer: I found two on the Blue Moon Butterfly. The BMB evolved with a new gene that renders male butterflies immune to the Wolbachia bacteria passed down from the mother which kills males before they hatched. The bacteria was discovered in the butterflies by Greg Hurst in the 1990s.
Explanation: To find them, look up "blue moon butterfly." One website should be called Berkely(.)edu. The other can be found by looking up "wolbachia butterfly." The website is called theatlantic(.)com.
