Answer: Dr. Balduzzi says it's important to remember that sweat is your body's main evaporative cooling system -- kind of like an internal fan. If you're exercising in cold air, your body doesn't need to produce as much sweat to keep you cool.
Explanation:
Answer: B. Removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.
Explanation: Something to do with photosynthesis and the ecosystem service of cycling carbon dioxide. Just got this correct on my online course
Answer:
i would like to choose sublimation process to explain about water cycle.As mentioned, sublimation is the process in which snow melts and water get vaporized. Ice melts and turns into water which flows to the seas and oceans.When the temperature increases during the day time, water gets vaporized.Water vapour begin to move upward.As we know, temperature decreases with the increase in height.Due to which water vapour rises,cools and then changes into tiny water molecules.Those water molecules forms cloud.Then the clouds get heavier and begin to collide with each other.As a result rain fall occurs.
Evapotranspiration has also the same process but the difference is that it involves vaporization of water from some biological factor like plants and physical factor like from soil .
i think its my first longest answer which i answered here.Thank you for the amaizing question. Its simple but most important topic
C. a Y chromosome from his father
This is because boys have one X and one Y chromosome, while girls have 2 X's, so the Y must come from the father.
Hope this helps :D
Options:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
B. Reactions that involve enzymes require more energy than reactions without enzymes.
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines.
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.
Answer:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
Explanation:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines. - this is true. Lactase is an enzyme that catalyses the breakdown of lactose. This means it greatly reduces the activation energy required for the breakdown of lactose, and the reaction will happen quicker.
B. Reactions that involve enzymes require more energy than reactions without enzymes. This is false. Reactions that involve enzymes require less energy that reactions without
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines. This is false. It will speed it up
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present. This is false, more energy is required if it is not present
