Answer:
Missed period
Explanation:
Symptoms of early pregnancy can include a missed period, an increased need to urinate, swollen and tender breasts, fatigue, and morning sickness
Introduction :-)
The <em>amniotic fluid</em> is the protective liquid contained by the <em>amniotic sac</em> of a <em>gravid amniote</em>. This <em>fluid</em> serves as a cushion for the growing <em>fetus</em>, but also serves to facilitate the exchange of nutrients, water, and biochemical products between <em>mother</em> and <em>fetus</em>.
Importance :-)
- <em>It helps to protect the fetus from trauma to the maternal abdomen.</em>
- <em>It cushions the umbilical cord from compression between the fetus and uterus.</em>
- <em>It has antibacterial properties that provide some protection from infection.</em>
- <em>It serves as a reservoir of fluid and nutrients for the fetus.</em>
<em></em>
Formation :-)
<em>Amniotic fluid </em>is present from the formation of the <em>gestational sac.</em> <em>Amniotic fluid </em>is in the <em>amniotic sac.</em> It is generated from <em>maternal plasma</em>, and passes through the <em>fetal membranes</em> by <em>osmotic</em> and <em>hydrostatic forces</em>. When <em>fetal kidneys</em> begin to function around week 16, <em>fetal urine</em> also contributes to the <em>fluid.</em> In earlier times, it was believed that the <em>amniotic fluid</em> was composed entirely of <em>fetal urine</em>.
The <em>fluid</em> is absorbed through the <em>fetal tissue</em> and <em>skin</em>. After <em>22 to 25 week </em>of<em> pregnancy</em>, <em>fraternization</em> of an <em>embryo's skin</em> occurs. When this process completes around the <em>25th week</em>, the<em> fluid</em> is primarily absorbed by the <em>fetal gut</em> for the remainder of <em>gestation</em>.
<em>Contents :-)</em>
At first, <em>amniotic fluid</em> is mainly water with <em>electrolytes</em>, but by about the <em>12-14th week</em> the <em>liquid</em> also contains <em>proteins, carbohydrates, lipids and phospholipids, and urea</em>, all of which <em>aid</em> in the growth of the <em>fetus</em>.
Hope its helpful :-)

Answer:
Given
Per Kg of body mass, there is 3 gram of potassium
And abundance of three isotopes are as follows
Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.
1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram
= 240*0.012/100 = 0.0288 gram.
2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg
Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10
Answer:
By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)
Explanation:
Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.
Answer:
The correct answer is option C-ANP (Atrial natriuretic peptide).
Explanation:
Vasoconstriction is the narrowing of the blood vessels which can stop or block the blood flow.
Vasoconstriction reduces the urine formation during stress conditions through the action of hormones like ADH (anti-diuretic hormone), norepinephrine, epinephrine and angiotensin II produced via the sympathetic nervous system.
The atrial natriuretic hormone (ANP) is a cardiac hormone produced to lower the blood pressure or reduce blood plasma through vasodilation, increased vascular permeability and increase renal excretion.
Thus, option C is the correct answer.
