Sedaia [141]

The amount of water reabsorbed during the formation of urine can be changed by hormones, enabling the creation of either concentrated or diluted urine. The duct serves this purpose.

In heating, ventilation, and air conditioning (HVAC), air is delivered and removed by ducts, which are conduits or passageways. Examples of the necessary airflows include supply air, return air, and exhaust air.  As part of the supply air, ducts frequently deliver ventilation air as well. As a result, air ducts are one way to guarantee both thermal comfort and adequate interior air quality. The brain releases a substance called antidiuretic hormone (ADH), which makes the kidneys release less water and reduces the volume of urine generated. The body makes less pee when its ADH level is high. A low

inn [45]

Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

Answer:

Meiosis

Explanation:

Meiosis is one of the two types of divisions that cells usually undergo. However, meiosis is unique to sexually-reproducing organisms. Meiosis is the cell division which results in daughter cells with a reduced number of chromosomes (by half). Meiosis is used to produce gametes in sexually reproducing organisms.

According to the question, Labrador retriever contains 78 chromosomes in each of its muscle cells, which is a somatic cell. Since Labrador retrievers are sexually reproducing organisms, a male one will produce gametes (sperm cells) via the process of meiosis. At the end of the meiotic process, sperm cells with 39 chromosomes each will be produced.
