1.The process of leaf color change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
2.The leaves in hot or dry environments may be adapted to reduce transpiration. For example, their stomata may be open at night and close midday. This is the reverse of what usually happens, and it means that the stomata are closet when the rate of transpiration would be greatest.
Answer:
The suspect might be guilty, but more information is needed from other parts of the investigation.
Explanation:
Due process states innocent until proven guilty. Having an 80 percent chance of deception is not solid proof of anything. It does, however, bring more speculation to the table that this person is indeed guilty, but because there is no actual proof, the investigators must find more information on the matter.
Answer:
Option B, Mammals and reptiles in the post-dinosaur age.
Explanation:
Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.
Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.
Hence, option B is correct
The answer is B
Hope this helps
Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
