Answer: I would say its probably A I'm not sure but that might be it
Explanation:
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
Because they take place at an atomic level and are unable to be seen by the human eye
Answer:
The correct answers are -
A. Find the absolute age of rocks at both locations.
B. Compare a layer at one location to layers at other locations
C. Identify index fossils in one or more layer at one location.
Explanation:
A scientist who studied the earth and different aspects such as it's structure and the materials it made if up known as a geologist. Classifying rocks and discovering various components and matter on earth are the major duties of a geologist.
At some point, rocks can be located at a distance beyond the reach of geologists. Nevertheless, they have a way of studying, and comparing the layers of those rocks helps them to understand the basic difference in the earth locations and the presence of certain components of earth.
Comparing rocks and layers can include these steps at first by geologists-
A. Find the absolute age of rocks at both locations.
B. Compare a layer at one location to layers at other locations
C. Identify index fossils in one or more layer at one location.
