"According to the Bohr model an atom has a nucleus with electrons in circular orbit around the nucleus. For a bohr model of Nitrogen there will be 2 orbitals with the first one having 2 electrons and the last orbital having 5. Whereas for the Bohr model of Neon there will be 3 orbitals the first one having 2, the second one having 8 and the last one having 7 electrons."
This answer was by TheMysteriousGamer11, I couldn't have thought of a better way to explain.
These base pairs (adenine with thymine and cytosine with guanine) are significant because the rule allows a corresponding strand of DNA to be replicated. (New strand can be created with the template)
Answer:
E) In both mosses and ferns, moisture is required for sperm to reach the egg. In mosses, gametophyte is the dominant stage of the life cycle. In ferns, the sporophyte is the dominant stage of the life cycle.
Explanation:
The *sporophyte of fern plant is dominant over the smaller and nutritionally independent gametophyte*. The sporophytes are photosynthetic, long-lived and highly branched. *Sperm cells of fern possess whip-like flagella in their cell walls that enable moisture swim to reach the egg*
*In Mosses,the gametophyte is more prominent (dominant)* just like in lower plants. These organisms *require external water(moisture) in the form of dew or rain to move their sperm during fertilization*.
Therefore, *In ferns, the sporophyte is dominant over the gametophyte*, while *in mosses,gamatophyte is dominant over the sporophyte.* Both require moisture for sperm to reach egg.
Insulin is released into the blood when oxygen levels are low and blood glucose levels are high
Los pulmones y el sistema respiratorio permiten la entrada del oxígeno del aire en el organismo, así como la expulsión de dióxido de carbono al espirar. La respiración es el término que se utiliza para denominar el intercambio de oxígeno procedente del entorno por el dióxido de carbono que se produce en las células.
