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.

zavuch27 [327]

Answer:

Three different genotypes and two different  colors

Explanation:

Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.

hope this helps!

Atoms of which element contain 25 protons? magnesium (Mg) aluminum (Al) tin (Sn) manganese (Mn) Which element has an atomic numb
mixer [17]

Answer:

1)Manganese (Mn)

2)Sulfur(S)

Explanation:

Atoms of which element contain 25 protons?

It is Manganese.

The atomic number of an element is the number of proton in the nucleous of an atom of the element. Here proton= 25= atomic number.

The number of proton helps to identify the particular element. In the modern periodic table, the elements are arrange base on how the atomic number is increasing. Then Manganese has atomic number of 25.

✓Which element has an atomic number of 16?

It is Sulfur, as explained earlier, the number of pron in the atom of the sulfur element is 16.

Suppose the human trait for freckles is controlled by a simple dominant and recessive relationship at one locus. Freckles, F, is
Dennis_Churaev [7]

Answer:

0.549 is the frequency of the F allele.

0.495 is the frequency of the Ff genotype.

Explanation:

<em>FF </em>or <em>Ff</em> genotypes determine freckles, <em>ff</em> determines lack of freckels.

In this class of 123 students, 98 have freckles (and 123-98= 25 do not).

If the class is in Hardy-Weinberg equilibrium for this trait, then the genotypic frequency of the ff genotype is:

q²= 25/123

q²=0.203

q= \sqrt{0.2

q= 0.451

<em>q </em>is the frequency of the recessive f allele.

Given <em>p</em> the frequency of the dominant F allele, we know that:

p+q=1, therefore p=1-q

p=0.549 is the frequency of the F allele.

The frequency of the Ff genotype is 2pq. Therefore:

2pq=2×0.549×0.451

2pq=0.495 is the frequency of the Ff genotype.
