Answer:
true
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
Answer:
These 3 receptors are different from each other. They do differ from each other by their location and function.
1. Testosterone receptor : It is an Androgenic receptor
2. Ferrotransferrin receptor : It acts as an element-binding protein which is iron responsive.
3. Fibroblast growth factor : It acts as a growth factor.
Explanation:
1. Testosterone :
Location- Xq 11-12 in the X chromosome.
Function-
- maintains male skeletal integrity by osteoblast and osteocytes.
- maintains female sexual, somatic and behavior.
- develops male sexual characters.
2. Ferrotransferrin :
Location- chromosome 3q21
Function-
- intakes iron in the cell.
- maintains the cellular iron equilibrium.
- post-transcriptional modification.
3. Fibroblast (growth) :
Location- chromosome 4p16.3
Function-
- helps in bone development.
- helps in bone growth maintenance by ossification.
The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it. The same sound will travel at a different speed on a cold day than it would on a warm day.
