Specific cells of the tissue at retina moves the light signals the thypothalamus.
At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.
You have also the total power generated is 200W
To figure out the kind of exercises, you need to master the definition of each unit. for example
power: watt (W) is
joule/secWork: is Newton. meter =
Joule
To obtain the work done by the adult, we have to convert the power (watt) into a work by multiplying by the time (
* seconds = Joule)
10 minutes is 60 * 10 =
600 seconds200Watt * 600 second = 120000 joules =
120 Kj
So the work is 120Kj
I believe the correct response would be D. Complementary to part of one strand of DNA.
Answer:
1. Cartilaginous joints
2. Freely movable (Synovial) joints
3. Temporomandibular joint
4. Arthritis
5. Synchondrosis
Explanation:
1. Cartilaginous joints are those who permits some movements but provide less stability that immovable joint, these joints are slightly movable.
2. Freely movable joints are synovial joints. These joints have a joint cavity between connecting bones, and allow for greater mobility. However, they are less stable than fibrous and cartilaginous joints. For example: elbow.
3. Temporomandibular joint is a like a hinge and a ball and socket joint at the same time. It is a simple hinge that permits to chew.
4. Arthritis is a term that describes inflammation in joints. Some of them include: rheumotaoid arthritis, psoriatic arthritis, etc.
5. Synchondrosis is a joint in which the articulating surfaces are close together but are bound by a hyaline cartilage, which can converts to either bone o fibrocartilage.
