Answer:
d. One additional neutron
Explanation:
Phosphorus-32, a radioactive variant of phosphorus, possesses 15 protons and 17 neutrons.
Conversely, Phosphorus-31, the most prevalent isotope of phosphorus, contains 15 protons and 16 neutrons.
This indicates that one isotope has one more neutron than the other.
I believe the functions of the digestive system typically increase when influenced by parasympathetic impulses. The parasympathetic nervous system is one of the three divisions of the autonomic nervous system, often known as the rest-and-digest system. It conserves energy by reducing heart rate, enhancing intestinal and gland activity, and relaxing sphincter muscles within the gastrointestinal tract.
Respuesta:
D
Explicación:
Para que las células se dividan, deben replicar su ADNy los orgánulos, y para que las nuevas células sean del mismo tamaño que las demás, también deben crecer.
Answer:
The elements are hydrogen, oxygen, nitrogen, and carbon.
Explanation:
Together, they constitute more than 99% of the mass in most cells and are the lightest elements able to create one, two, three, and four bonds correspondingly.
The key takeaway is that various substances have distinct biomass proportions. Variations in biomass percentages exist due to the differing elemental compositions of these substances. Each biomass is constituted by elements like carbon, hydrogen, nitrogen, and oxygen. For instance, the human body comprises 30% biomass, while the remainder consists of water. The breakdown of various elemental percentages includes carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%), and phosphorus (0.14%). At every level, only 10% of biomass is transferred to the next level, with the remaining 90% being dissipated as heat.
