問5で(3)の訳が問われているのですが なぜafter等もないのに4時間"後"と訳せるのですか?

In a study published in the July 11, 2016, Current Biology, researchers found that exercise after learning may improve your memory of the new information, but only if done in a specific time window *2. (In the study, 72 participants learned 90 picture-location associations mentally linking an image with new information in order to improve recall over a 40-minute period. They were then randomly assigned to one of (1) three groups: one group exercised immediately, the second exercised four hours later, and the third did not exercise. The exercise routine consisted of 35 minutes of interval 10/training on a fitness bike at an intensity of up to 80% of maximum heart rate. After 48 hours, the participants' memory was tested while their brains were scanned*4 via MRI*5. Those who exercised four hours after the learning session retained*6 information better than the other two groups. The MRI also showed the hippocampus, the brain region involved with learning and memory, - that (2) 15 was more active when information was recalled correctly. Newly learned information turns into long-term knowledge through a process that requires certain brain chemicals that are released during exercise, but more research is needed to understand (3) this phenomenon. (4) It is also not clear why four hours was more beneficial, or if another time frame might produce a similar 20 effect.

線が引いてある「a flat of」の意味が良く分かりません…どなたか教えてほしいです…!

5 without touching a keyboar 1 Much of what we eat today comes to our tables from other areas. Today, 1) walking ruch of wil through the aisles of a grocery store is almost like taking a trip around the world: strawberries from Chile and *Asian pears are available in the middle of winter. Americans have come to expect constant variety in their diet, wherever they live, whatever the time of year. This means we must often import our food from around the world. It is important to understand how this affects our Earth. 2 When food has to travel great distances, it is not just *shipping that is expensive; the environmental impact is also costly. For example, the true cost of transporting *a flat of strawberries from Chile to a grocery store in the United States must also take into account the *manpower, *fossil fuel consumption, and *carbon emissions. 3 The phrase "food miles" means the number of miles a product must travel in order to reach the consumer. A flat of strawberries from Chile *shipped to Ohio has traveled more "food miles" than a flat from California. Measuring food impact on the Earth must also take into account weather (strawberries grown in *hothouses have a bigger *carbon footprint than those grown in sunlight) and transportation type (*ocean freighters use less fuel than aircraft). "Food miles" are a rough but crucial calculation el than airc #5082 5) of the environmental impact of our foods. They can help us assess the full costs of our food choices.msdt gaidonot juodliw 21slugmos seu 240 words) aid ovom of oly boldeas and colorife) bosheidque ed gain a lobizoi erotuomos llamadiw abrudbed gansow 」である.

至急お願いいたします🚨 生物の質問です。 ミトコンドリアの経路についての説明だと思うのですが、電子オーバーフローモデルと電子分布モデルの違いを教えていただきたいです。 また、どういう仕組みなのか、何故このように電子が流れるのかも教えていただきたいです。 UQ poolはユ... 続きを読む

(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive. Alt No alternative pathway activity Cytochrome pathway unsaturated Cyt (B) Electron distribution model (reflects current thinking) UQ pool Cyt Alternative pathway active Cytochrome pathway saturated Alt Alternative oxidase active Alt UQ pool Cyt Cyt Figure 14.33 Two models for regulation of electron flow through the alternative oxidase. (A) In the electron overflow model, no appreciable electron transfer through the alternative pathway takes place until electron flow through the cytochrome pathway is at or near satu- ration. This could result from the effects of respirato- ry control, if the rate of mitochondrial ATP produc- tion exceeds its rate of utilization in the cytosol, or from some externally imposed stress, such as low temperature. Under such circumstances, the UQ pool becomes sufficiently reduced to allow electrons to flow through the alternative oxidase, the latter re- quiring that the UQ pool be 40% to 60% reduced to attain significant activity. (B) In the electron distribu- tion model, the alternative and cytochrome path- ways both show significant activity at low levels of UQ pool reduction, and electrons are distributed be- tween the two pathways on the basis of the relative activities of each pathway. The activity of the alter- native oxidase under these circumstances is thought to be regulated by the action of a-keto acids and by reduction/oxidation of the intermolecular disulfide bond, as well as by additional regulatory mecha- nisms not yet characterized.
