To remove all fall risks in the area,(rugs, electrical cords, O2 tubing..etc)
To balance out negative charges on the interior of the membrane, voltage-gated sodium channels open, allowing sodium ions to enter the cell.
There are two factors that draw sodium ions (Na+) to the inside of neurons while they are at rest. The (Na+) ion is pushed into the cell down the concentration gradient by the high concentration of (Na+) outside the cell. Similar to how the positively charged (Na+) inside the neuron is drawn in by the electrostatic pressure caused by the negative charge inside.
Which of the four ion channel types are they? Ion channels that are voltage-gated, Linguistic-gated ion channels (also known as ionotropic receptors), ion channels with light-gated, Ion channels with mechanosensitivity, Nucleotide-gated ion channels that cycle, and Ion channels that are calcium-gated.

b) One with spiny leaves and a thick stem.
Explanation:
- Plants growing in desert face scarcity of water and they need to check transpiration rate.
- To reduce the rate of transpiration the leaves of desert plands are reduced to spines, which resulted in a reduced surface area and negligible number of stomata.
- The Stems of Desert plants are modified to store water to prevent desiccation and hence they are thick and succulent.
Answer:
Changes in allele frequencies over time can indicate that genetic drift is occurring or that new mutations have been introduced into the population.
The answer is A- a active immunity.
