a response Pregnant women also experience back pain as their posture adjusts to accommodate the weight of the growing uterus. The back curves inwards while the belly curves outwards, placing pressure on the back and potentially causing pain. AQI of 7.2 (tests Learning Outcome 7.3) During the first 20 weeks of pregnancy, a pregnant woman gained 2 kg, then 0.5 kg per week for the next 10 weeks, and finally 0.1 kg for the final 10 weeks. At full term, what is her total weight gain? What does this imply could be going on?
For the first 30 weeks of her pregnancy, this woman’s weight gain was normal: she gained 2 kg in the first 20 weeks and 0.5 kg per week for the next ten weeks. She should have gained 0.5 kg per week from 30 to 40 weeks, but her weight gain slowed to 0.1 kg per week during this period. It’s impossible to say if this sluggish weight gain at the end of pregnancy indicates that the fetus isn’t developing normally, so it should be checked out at a medical facility. Some women have regular pregnancies with little weight gain, while others have a fetus with intrauterine growth restriction (IUGR). Why is it necessary for pregnant women to eat more iron-rich foods or take iron tablets? SAQ 7.3 (tests Learning Outcome 7.4)

Regulatory approval and actual distribution/rollout into the population are now at the start of the vaccine endgame. The evidence for the Pfizer/BioNTech and Moderna vaccines continues to look promising (here’s a new study on the durability of immune response following the Moderna one), while the J&J and Novavax attempts are still pending. Due to some very bad communication about their clinical practice, the AZ/Oxford nominee is something of a mystery (which suffered from some fundamental problems itself).
Now we just need to find people willing to take them. According to surveys, there are still a significant number of people who are (at the very least) in the “why don’t you take it first” camp. I believe that as vaccine dosing becomes more common, more people will line up for vaccinations, although this remains to be seen. But there’s one thing I’d like to bring up that we should all remember.
If those ten million people were instead given a new vaccine, there’s a good chance those heart attacks, cancer diagnoses, and deaths will be blamed on the vaccine. I mean, if you reach a big enough population, you’re going to have cases where someone gets the vaccine and dies the next day (exactly as if they hadn’t gotten the vaccine). However, persuading the person’s friends and family of their lack of connection may be difficult. The fallacy of post hoc ergo propter hoc is one of the most powerful in human reasoning, and it’s not going anywhere anytime soon. Vaccines, in particular, are a case in point. I believe the most we can do is try to spread the word ahead of time. People get sick and die all the time in this country, so let people know that this is going to happen. The key would be if they get sick or die at a significantly higher rate after being vaccinated.

The voice box is also known as the larynx. It’s at the top of the windpipe. Two vocal cords are spread around the voice box, or larynx, leaving a small slit between them for air to move through (Fig. 13.12). The vocal cords vibrate and produce sound as lung force air passes through the slit. The muscles that connect to the vocal cords may tighten or loosen them.
Take a metal plate as an example (or a shallow pan). It should be hung in a suitable location that does not touch any walls. Hit it with a stick now (Fig. 13.1). With your finger, softly touch the plate or pan. Can you sense the tremors? Strike the plate with the stick once more, this time holding it firmly in your hands. Is the echo still audible? After the plate has stopped making noise, touch it. Can you sense any vibrations now?
The sensation is felt as we softly strike the pan with our finger after hitting it. We don’t hear the echo if we keep the pan tightly after hitting it. When the pan stops vibrating, it also stops making vibration. As a result, we can deduce that a vibrating body generates vibration.
