Answer:
Explanation:
El impulso nervioso es un impulso eléctrico. Para que el impulso eléctrico se transmita, los iones positivos de sodio que están en estado de reposo y están presentes fuera de la neurona deben traspasar la membrana celular. En la medida que el impulso avanza por la membrana, su interior recobra la carga negativa.
The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence
Explanation:
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.
Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy show with the same name premiered on CBS. The show follows the home and academic life of several researchers

In simple words, osteoporosis can be stated as the medical state in which the bones become breakable and weak from loss of tissue. Due to the deficiency of calcium or vitamin D.
<u>Explanation:</u>
<u>Environmental factors that influence osteoporosis:</u>
- Due to smoking, and consuming alcohol leads to the Osteoporosis.
- Intake of Poor diet food and intake of low calcium can leads to Osteoporosis .
- Chronic diseases like arthritis and liver infection can cause Osteoporosis .
- Due to the Malabsorption, it will lead to Osteoporosis .
- Vitamin D helps the body to absorb calcium.
- When vitamin D is wanting, the body cannot absorb sufficient amounts of calcium to inhibit osteoporosis. Some medications can cause osteoporosis.
Such changes would occur mostly likely near or in the active binding site of the enzyme.
Because the drugs used are competitive inhibitors of the <span>HIV reverse transcriptase enzyme, it means that they connect directly to the active binding site of this enzyme not allowing it to preform its function. If the mutations impede this drugs to work, it is probably because they alter the active binding site of the enzyme, not allowing the drug to bind and have its competitive behaviour permitting the enzyme to work normally. </span><span /><span>
