It is the border brush enzyme.

Border brush enzymes are hydrolytic enzymes bound to the microvilli of columnar epithelial cells of the small intestines. They are produced by pancreas, and are ducted by main pancreatic duct. They are responsible for the final and terminal stage of digestion of dietary carbohydrates and proteins. They transport the resulting amino acids and sugars into the epithelial cells.

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>

Explain why the amount of rainfall a region receives is a better determination of whether it is a desert than temperature.
Gnoma [55]
<span>As there are many kinds of deserts, some hot, some cold even arid deserts are the classic hot deserts, but there are also cold and coastal deserts where temperatures do not get so high. The element common to all of these types of deserts, however, is their lack of rainfall. In that sense the rainfall is a characteristic that determines if it's a desert.</span>

A hospital can demonstrate inclusivity by community engagement through:
astraxan [27]

We knew hospitals as places where people get treatment. We hardly imagine hospitals doing outreach to the community outreach nowadays. Community outreach may improve patient outcomes, which is crucial for the hospital to have access to payer’s reimbursements. One good example is giving outreach to churches, since these institutions often have older and often sicker, individuals. The hospital may directly engage with the church and give health education and smooth transition from hospital to home. The hospital may also embrace social media, or use Twitter to data-mine flu outbreaks in the community.

Bacteria is a prime candidate for genetic engineering because of its ___________ and ____________?
N76 [4]

The given blanks can be filled with the ability to take up foreign DNA and express proteins faster.  

The direct manipulation of the genes of an organism with the application of biotechnology is known as genetic engineering. It is an array of technologies that are utilized to modify the genetic make-up of an organism, involving the transfer of genes across and within the boundaries of the species to generate novel or bettered organisms.  

In genetic engineering, bacteria play a key role, as it is an essential tool for natural scientists. The genes and other genetic information from a broad array of species can be administered into bacteria for modification and storage, thus producing genetically modified bacteria in the procedure.  

The bacteria possess the tendency to take up foreign DNA and expresses the desired proteins at a faster rate.
