The finger like projections of the small intestines are called?

Biology
1 answer:
Rus_ich [418]3 years ago
7 0

Answer:

The finger like projections of the small intestines are called villi.

Explanation:

The structure of villi is just like human finger. Villi increases the surface area of small intestine which increases the absorption. Villi is a part of small intestine which is responsible for the absorption of nutrients that are present in the food particles. These nutrients are again combined with the blood and used by the body. Villi do not helps in the digestion of food substances, they can only absorb.

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimil
Arada [10]

Answer:

Dissimilatory- oxygen absent

Assimilatory- high concentration of nitrite

Explanation:

In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes

Debido a la baja cantidad de calorías que utilizamos o quemamos en un día de trabajo
Delvig [45]

Answer: Se debe a que el cuerpo lleva a cabo funciones fisiológicas vitales que requieren energía.

Explanation:

Las calorías son unidades de energía aportadas por los alimentos que consumimos a diario. Puntualmente se define la cantidad de calor necesaria para aumentar en 1 grado centígrado a la temperatura de 1 gramo de agua desde 14,5 hasta 15,5. La principal fuente de calorías en los alimentos son los hidratos de carbono, luego le siguen las grasas y proteínas.

<u>Dicha energía hallada en los alimentos, es utilizada por el cuerpo para llevar a cabo distintas funciones fisiológicas vitales e importantes para que el organismo funciones correctamente</u>, como el bombeo de sangre del corazón, funcionamiento de los riñones o el actividad del cerebro, etc. Nos referimos a esto como el metabolismo basal, el cual es el valor mínimo de energía utilizada en reacciones químicas celulares para la supervivencia del organismo. Dicho metabolismo basal depende de diversos factores tales como la edad, peso, sexo, etc. Pero también, las calorías son necesarias para distintas actividades voluntarias como caminar o levantar algún objeto.

<u>Sin embargo, la forma de energía de las calorías de los alimentos es distinta a la forma de energía necesaria para llevar a cabo estas funciones fisiológicas tanto voluntarias como involuntarias.</u> Para ello, la energía de las calorías debe de convertirse a otra forma y esto ocurre comenzando primero con la digestión de los alimentos, donde luego sus nutrientes son absorbidos en el torrente sanguíneo para luego dirigirse a las células. En las mismas, ocurre un proceso llamado respiración celular, en donde se utilizan las calorías de los alimentos para sintetizar ATP (Adenosín Trifosfato), la cual es una molécula que almacena energía utilizable por parte de las células y que eventualmente impulsará y llevará a cabo todos los procesos fisiológicos y metabólicos.

Entonces, en el caso del trabajo de una oficina en el que las personas permanecen sentadas largas horas, sin mucha actividad, <u>igualmente necesitan consumir mas de 2.000 kilocalorías diarias ya que el cuerpo debe obtener esa energía para llevar a cabo las funciones de todos los órganos para mantenerlos vivos.</u>
