The series of hormonal events that leads to birth:
- Fetal cortisol stimulates the placenta to secrete estrogen.
- The high estrogen level stimulates the uterus to form oxytocin receptors.
- Prostaglandins dilate the cervix, and with oxytocin, increase the strength of uterine contractions.
- Oxytocin stimulates the placenta to secrete prostaglandins.

- Oxytocin: It helps in the uterine contractions during parturition.

Blood, a fluid connective tissue, provides a transport system within our body for oxygen and other important substances. Cartilage provides strong support and connection for our skeletal framework. And the function of bones is to support and protect soft tissues and organs in our body.
Answer:
Option). It permits hydrogen bonds between DNA strands to dissociate.
Explanation:
PCR (polymerase chain reaction) techniques can bed defined as a technique, which is used for in vitro amplification of sample DNA. It is made up of three steps, denaturation, primer annealing, and extension.
The first step in PCR is heating of sample DNA to denature the double stranded DNA by breaking hydrogen bonding present between bases of double stranded DNA.
Due to this, double strands of DNA get separated and provide templates for synthesis of daughter DNA strands.
Thus, the correct answer is second option.
<span>The research shows that the relationship between estrogen and verbal tasks is negative while it is positively correlated with spatial tasks. This correlation shows that, like in other animal studies, there could be some sort of organizing of the brain that goes on related to the level of sex hormones in the body.</span>
