What is the exact question ????????????
The enzyme that breaks down H2O2 is called catalase.
Answer:
B
Explanation:
Hello!
Let's define each choice and see what choice fits the criteria the most.
Temperate grasslands are open grassy areas with some population of trees, usually having around 500-900mm of rainfall every year.
Tropical rainforests usually do not have a dry season and rain all year round; it has around 1,800 to 2,500 mm of rainfall.
Tropical deserts don't have much cloud cover, hence why they won't get much rainfall. They're irregular and might only get around 250mm of rainfall per year.
Knowing this information, we can also see on the graph that there had been approximately 2100mm of rainfall this year, which helps us conclude that tropical rainforests are the correct answer with the rainfall range.
The structures are nephrons which gets blood through the [renal artery]. The nephrons also consist of the [afférent and efferent artérioles], the latter of which is much narrower causing a high pressure to exist in the [glomerulus] (blood vessels in that ball structure) so that ultrafiltration can occur and the ultrafiltrate is passed into the [Bowman’s capsule]. The Bowman’s capsule consists of podocytes which are cells that form a microscopic pore so that small molecules can pass through (ions and such). There is the [proximal convoluted tube] that makes the contents flow downwards (and allows water to exit so the water potential inside is low) and the [distal convoluted tube] that makes the contents go upwards (and allows water to re-enter which increases the water potential inside). These are both partially permeable and set up a concentration gradient for the reabsorption of water from the urine. These tubes lead into the [collecting duct] which further reabsorb the water.
All the structures of the kidney are in [ ].
Answer:
En los seres vivos acuáticos el oxigeno es tomado del <u><em>agua</em></u> y penetra a la célula por el fenómeno de <em><u>respiración branquial.</u></em>
Explanation:
La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno. Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.
La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.
El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.
Es decir, <em><u>en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.</u></em>
