Answer:
Podemos suponer que este estudiante tiene insuficiencia de la hormona de crecimiento (somatotropina) que la secreta la glándula hipófisis y se encuentra en la base del cerebro. Esta hormona no ingresa a las células en su mecanismo de acción por ser peptídica o no esteroidea.
Explanation:
En este caso presentado se encuentra una situación diferente a lo que sucede en el gigantismo: hay un problema hormonal en donde la hormona de crecimiento es secretada de manera excesiva. Recibe el nombre de acromegalia cuando sucede después del cierre de la epífisis del hueso, luego de la edad de crecimiento.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
Answer:
Eventually the IR photons escape into space, but some make several round trips between the ground and the atmosphere before they depart. Along the way, a lot of energy is transferred to the ground and the atmosphere. That energy becomes heat which warms Earth's surface and its atmosphere.
Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
