Given what you know about the effects of lead on the body

CaHeK987 [17]

Answer:Lead is more dangerous to children than adults

Explanation:

They often put their hands and other objects in their mouths that can have lead dust on them. Their growing bodies absorb more lead. Their brains and nervous systems are more sensitive to the damaging effects of lead.

The [α] of pure quinine, an antimalarial drug, is −165. If a solution contains 69% quinine and 31% of its enantiomer (ee = 38%),

Elis [28]

Answer: The required [a] for slotion will be -62.7

Explanation:

The specific rotation of pure quinine= -165

% of pure quinine= 69%

% of its enantiomer=ee=31%

Enantiomer excess =(ee)=excess of a single enantiomer/entire mixture×100

Now,

Excess of a single enantiomer=69% - 31%=38%

Entire mixture=69% + 31%= 100%

(ee)=38/100 × 100

=38%

Net rotation= 0.69-0.31=0.38

Hence, [a] for solution will be = -0.38×165= -62.7

Aminiotic fluid formation and clearance ?

stich3 [128]

Introduction :-)

The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus.

Importance :-)

It helps to protect the fetus from trauma to the maternal abdomen.
It cushions the umbilical cord from compression between the fetus and uterus.
It has antibacterial properties that provide some protection from infection.
It serves as a reservoir of fluid and nutrients for the fetus.

Formation :-)

Amniotic fluid is present from the formation of the gestational sac. Amniotic fluid is in the amniotic sac. It is generated from maternal plasma, and passes through the fetal membranes by osmotic and hydrostatic forces. When fetal kidneys begin to function around week 16, fetal urine also contributes to the fluid. In earlier times, it was believed that the amniotic fluid was composed entirely of fetal urine.

The fluid is absorbed through the fetal tissue and skin. After 22 to 25 week of pregnancy, fraternization of an embryo's skin occurs. When this process completes around the 25th week, the fluid is primarily absorbed by the fetal gut for the remainder of gestation.

Contents :-)

At first, amniotic fluid is mainly water with electrolytes, but by about the 12-14th week the liquid also contains proteins, carbohydrates, lipids and phospholipids, and urea, all of which aid in the growth of the fetus.

Hope its helpful :-)

If so, please mark me as brainlist :-)

you have been performing chest compressions for about 2 minutes with another healthcare provider delivering the breaths. an aed

Aliun [14]

An AED is in use and has indicated that a shock is needed, the second rescuer should start compressions immediately after delivering the shock to the individual.

This is referred to as Cardiopulmonary resuscitation and is an emergency lifesaving technique performed when the heart stops beating.This include series of compressions and artificial ventilation so as to ensure the brain functions are preserved.

In the case where an automated external defibrillator (AED) is used and indicates a shock is needed, it is best to give it immediately.

This should then be followed by compressions from the second rescuer which is therefore the reason why it was chosen as the correct choice.
