Answer:Enrico must multiply the distance of mars from sun (meters) with the to convert the distance in astronomical units.
Explanation:
1 astronomical unit =
Let the distance between the sun and Mars be Y( meters)
Distance in AU=
Enrico must multiply the distance of mars from sun (meters) with the to convert the distance in astronomical units.
Answer:
Lysosomes
Explanation:
Salivary glands are secretory cells. Therefore, they have a very well-developed secretory system.
Lysosomes store secretory proteins and are important for keeping them sequestered from the rest of the cell, and eventually delivering them outside the cell.
Answer:
False. The driving for is the partial pressure gradient of O2 (PO2 difference), not the PCO2 gradient.
However, keep in mind that an increase in PCO2 can facilitate the unbinding of oxygen from hemoglobin. This is due to a decrease in pH associated with PCO2 increase. The H+ ions bind to hemoglobin and decrease it's affinity for oxygen, this is called the bohr effect. But the PCO2 is not the main driving force of oxygen unbinding.
