Breast tenderness would be considered a presumptive sign of pregnancy.
The fertilization of sperm and ovum occurs at ampulla isthmic junction of fallopian tube. This ovum travels to the uterus and joins with the uterus for further development. Two weeks after the fertilization or conception, pregnancy is said to begin.
This is accompanied with missed periods or menstruation. Other important presumptive signs include nausea, vomiting, breast tiredness, back pain, poor sleep etc. In humans, the pregnancy or gestational period lasts for around 40 weeks or 80 days. Estrogen, progesterone and human chorionic gonadotropin are the three hormones that rise at the start of pregnancy.
Estrogen regulates progesterone and increases blood flow while progesterone prepares the uterus for implantation of fertilized ovum. The third hormones indicates the creation of placenta.

Answer:
B.F Skinner´s studies led him to the idea that children learn language through operant conditioning. Applying positive reinforcement when a child uses a word correctly helps him to learn the association between that word and its meanings.
Explanation:
Celebrating a child for producing sounds that are close to a word reassures him and makes him repeat it. On the other hand, ignoring sounds that aren´t similar to any words makes the child forget about them. Based on his theory, Skinner developed a teaching process for language development based on the reinforcement of correct use of language. Let's imagine a child that says the word "milk" or a sound similar to that word. If he´s given milk after that and praised about it, he will learn the relationship between the word and its meaning and develop a language based on that information.

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
An unobtrusive data collection is a data collection technique used mainly in the social sciences to obtain or gather data without the researcher directly interfering or interfacing with the subject being studied. Thus, it doesn't influence the behavior, action or response of the subjects under study.
Hence, an example of unobtrusive data collection is examining body camera footage to determine the extent of excessive use of force among police departments.
