Answer:
Phenotypic ratio= 1 Brown : 1 Gray
Explanation:
Genotype of brown snake= BB
genotype of gray snake= Bb
A cross between brown (BB) and gray (Bb) snake obtains progeny in following phenotypic ratio= 1 Brown : 1 Gray
Here, the heterozygous parent, gray snake (Bb) forms two types of gametes in 1:1 ratio while the homozygous dominant parent, brown snake (BB) forms only one type of gamete.
Answer:
The correct answer is option C (voltage gated Na+ channels).
Explanation:
Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.
The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.
At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.
Thus, option C (voltage-gated Na+ channels) is the correct answer.
Answer: Option D
Explanation:
Phosphorus assists in energy metabolism.
It helps in the usage and storage of energy in the body. Also, whenever, phosphorus levels in the blood get too low energy levels tend to drop. This could lead to weakness in the muscles and fatigue
