Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
The resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
The system that is made up of those is called the Respiratory System
Answer:
A. The poles are opposite
Explanation:
Magnets are object that produce magnetic fields, which are regions of space that exert a forces on charged particles in motion or on other magnets.
Every magnet has 2 opposite poles, which are labelled by convention as North Pole and South Pole; the lines of the magnetic field of a magnet go out from the North Pole and go into the South Pole.
Magnetic poles always exist in pair: it means, every magnet always contains a North Pole and a South Pole. If a magnet is cut in a half, each half of the magnet will still have a North Pole and a South Pole.
Each pole exerts a force on another pole; in particular, we have:
- Like poles (north-north or south-south) repel each other
- Opposite poles (north-south) attract each other
In this problem, a magnet is attracted to a metal object: this means that the two poles must be of opposite polarity. Therefore, the correct option is
A. The poles are opposite
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.
