Answer:
The correct answer is: the group of 10 people that lifted the barbell with music is the control group.
Explanation:
The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.
The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.
<u>The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell</u>. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.
Robert Koch is best known for establishing a link between bacteria and disease.
Robert Koch was a German doctor that made an important contribution to the field of microbiology and public health. During his experiments he identified the particular microorganisms that cause diseases such as tuberculosis, cholera, and anthrax. Koch’s research resulted to the development of Koch's postulates, which are four general principles that links specific microorganisms (such as bacteria) to specific diseases and is being used today in medical microbiology as a standard.
Answer:
Gomphosis
Explanation:
Fibrous Joints:
Fibrous joints are immovable or fixed joints because they have the characteristic that they do not move. These joints have collagen which is a white connective tissue and it help in connection with other tissues.
Fibrous joints are mainly three types called sutures, gomphosis and syndesmosis.
Suture:
Suture is one of the fibrous tissue which only present in skull called cranal suture. There is tiny amount of movement present it sutures for elasticity of skull.
Gomphosis:
Gomphosis is found in the tooth which bind tooth with tooth socket bone by periodontal ligament. This joint is completely immovable.
*Peridontal ligament is the fibrous tissue which is present between tooth and tooth socket.
Syndesmosis:
Syndesmosis is found between tibia and fibula joint which is joined or connected by connective tissue (ligament). This fibrous joint is slightly moveable.
D- During interphase, when the cell is not dividing, chromatin is less tightly packed compared to our chromosomes, which allows transcription to occur.
