Answer:
A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C
Explanation:
Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).
That automatically eliminates Option B.
I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.
Option D is wrong because it includes no temperatures above body temperature.
Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.
That leaves Option A as the best answer. It includes only one temperature above 40 °C.
Answer:
They will have a large amount of genetic variation.
Explanation:
Scrapping pollens obtained from one plant to the flower of another plant (different variety but same species) would lead to increase in the genetic pool. The new hybrid plant would carry genetic features from both plants varieties. This process is also used to develop new varieties and have been recognized as cross-pollination. This process is generally preferred over genetic modification (GM) because of more nature friendly.
Answer:
they are very similar in what they are made of.

<span>Villi are hair-like structures covered with epithelial cells measuring 1.5 mm that line the mucous inner membrane of the small intestine. The epithelial cells of the villi contain microvilli and are responsible for the absorption of nutrients. Being so small and numerous, they effectively increase the absorptive surface area of the small intestine. When the surface area increases, this is the time they absorb the nutrients.
As for plants' root hair cells, they receive nutrients through osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water and minerals are transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.
As we can see, both of them utilize increasing their surface area.</span>
Answer:
Bíceps- tríceps
Explanation:
Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae y el bíceps (antagonista) se relaja.
