A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy), with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.
Answer:
Since a species' chromosome count doesn't change from generation to generation, meiosis requires that the number of chromosomes in germ cells be cut in half. Meiosis, unlike mitosis, achieves this accomplishment by requiring a single round of DNA replication followed by two rounds of cell division.
Water travels from roots to leaves, where it is used for photosynthesis.
It will increase blood
pH. This is because pCO2 also reduces. pCO2 is critical in the <span>maintenance of blood pH. Dissolved CO2 from respiring
tissues dissolves in blood to form carbonic acid. The carbonic acid partially dissociated
into H+ ions and its conjugate base (bicarbonate ions). Carbonic anhydrase
catalyzes the formation of carbonic acid (in tissues) and vice versa (in the lungs).
In the lungs, the carbon dioxide is expelled. </span>
