FALSE

In the currently accepted atomic model, an electron orbits around the nucleus is NOT in a clear, defined path.

Explanation:

According to modern atomic models, like the Bohr theory, it is difficult to know the exact location and path of an electron around the nucleus. This is partly because the mere act of observing the electrons changes its position. This is because the electrons have negligible mass and therefore ‘hitting’ them with any form of radiation for ‘illumination’ changes its position, behavior, and properties. In addition, the movement of electrons is very rapid such that by the time one observes the instantaneous location of an electron, if it was possible, it will have changed its position.

Therefore modern theories, such as VSPER, model atoms based on properties of where an electron will highly likely be found. This is how the shells and subshells of electrons (s, p, d, f) are modeled.

1. Answer;

It facilitates the movement of the fetus towards the pelvic girdle thus the child is born headfirst.

Explanation:

  • During labor the pelvic floor facilitates movement of the fetus towards the pelvic girdle by resisting the descent of the presenting part. This makes the fetus to rotate forwards and therefore results in majority of the fetus being born headfirst.  

2. Answer;

Purple pushing lead to development of pelvic floor problems.

Explanation

;

  • Purple pushing involves the midwife instructing a woman to hold her breath for ten seconds while forcefully pushing down during a contraction.
  • in the second stage instead of waiting for the mother to feel the instant urge of pushing which lead to development of pelvic floor problems.

3. Answer;

Exercise can help to strengthen the abdominal muscles and reduce the appearance of diastasis recti.

Explanation;

  • By contracting transversal abs muscles they strengthen and pull the muscles inwards.
  • The diastasis recti reduce with time due since the rectus muscles come close to each other enabling a human being to live a normal life because flexion, bending and stability becomes easy.

4. <u>Answer</u>

  • Pelvic floor muscles
  • Stomach muscles
  • Abdominal muscles
  • Perineal muscles
  • Uterine muscles

<u>Explanation</u>

  • Abdominal muscles are stretched to their limit by term. They greatly decrease the ability to perform strong contraction.
  • Pelvic floor is vulnerable to muscular and neurological injury during labor and delivery.  
  • Perineal muscle tightening strengthens the pubococcygeus muscle and increases its tone.

5. Answer and explanation;

  • Sports that can lead to falling down e.g. skating
  • Sports that may involve altitude change
  • Exercises that involve lying flat on your back
  • Exercises that involve holding o breath
  • Motionless standing

6. Answer

Yes

Explanation

;

  • Exercise maintains physical fitness, health and wellness aiding growth to the unborn since the mother gains enough strength and energy and there is proper blood flow.
  • Many pregnant women tend to gain weight which may lead to health difficulties for example struggling to breath. The pregnant lady is able to cope with labor and she is able to get back in shape after the baby is born.

7. <u>Answer</u>;

One is supposed to get up slowly and gradually to avoid dizziness.  

<u>Explanation;</u>

  • Dizziness happens after a tiresome activity done continuously for a period of time thus one should get up slowly and gradually to avoid other injuries like falling endangering the life of the unborn child.
