Germ layers form during the <u>germinal </u>period while organ systems mature during the <u>fetal</u> period.

The endoderm (inner layer), ectoderm (outer layer), and mesoderm are the three major cell layers that make up the germ layer. They arise in the early stages of embryonic development (middle layer).

The first two weeks following conception are known as the germinal stage, followed by the embryonic phase from the third to the eighth week, and the fetal period, which lasts from the ninth week until delivery.

A variety of procedures take place during the germinal stage to transform an egg and sperm first into a zygote and later into an embryo. The procedures include implantation, blastulation, cleavage, and fertilisation.

The _____ are responsible for the perception of rapid vibrations, such as you would experience when using a hand-held massager.

Andrej [43]

The Pacinian corpuscles are responsible for the perception of rapid vibrations, such as you would experience when using a hand-held massager.

In the bone periosteum, joint capsules, pancreas and other viscera, breast, and genitals, Pacinian corpuscles are found deep in the dermis of both glabrous and hairy skin. They are structurally similar to Meissner's corpuscles. They are fast adapting mechanoreceptors that detect high-frequency vibration and deep brief (but not persistent) pressure. By being crushed, The pacinian receptors sense vibration and pressure by stimulating their internal dendrites. Skin has less Merkel's disks and Meissner's corpuscles than Pacinian corpuscles and Ruffini endings.

A participant chooses someone else to participate on their behalf in a study or test. This happens in cases where it is not easy to fin the actual potential participants. It is called a snowball because when you roll a ball in an snpw it keeps attaching more snow until it gets bigger. The sampling is done randomly which means it is a non probability sampling

Snowball sampling consists of two steps:

The researcher will choose potential participants which are only few at the beginning. The chosen participants will recruits more participants, they don't have to give names. This recruitment goes on until the desired sample proportion is reached. The participants will only encourage others to come but that is not forced. It can be ethically challenging because subjects can be of sensitive topics

Why is Snowball Sampling Used?

In cases where a research deals with sensitive topics such as cheating, shoplifting, drug use and other deviant societal behaviours, participants may not feel comfortable to come forward. However they may suggest others in similar situation as them and be assured of confidentiality.
