Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.
When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.
The transport mechanism is carrier mediated it does not require energy.
Cancer is a mutation that occurs during the cell cycle, usually when it develops and grows it means the mutation was able to go through the cycle undetected at checkpoints so the cell was not destroyed by the lysosomes.
Desert vegetation or xerophytes includes bushes with deep roots and plants that store water.
Another name for desert plant:
A plant species known as a xerophyte has evolved to live in environments with little fluid water, like a desert or an area surrounded by ice or frost in the Mountains or the Polar regions. Cacti, pineapples, and various Gymnosperm species are a few well-known instances of xerophytes.
- Xerophytes have different adaptations to their morphological characters (morphology) and basic physiological functions (physiology) that allow them to store significant amounts of water and save it during dry seasons. During prolonged periods of severe dehydration or evaporation of their organs, some creatures can live, and at those times, their biochemical function may cease. Xeromorphic flora has such biological and morphological modifications.

Answer:
Innate immunity is a non-specific immune system which provides defence against any pathogenic microorganism in early stages. It includes physical barrier such as skin, chemical barriers such as saliva, tears, et cetera, phagocytic cells such as macrophages, et cetera.
Acquired immune system is the one which develops after exposure to pathogen or antigen. It is highly specific in nature. It includes B-lymphocytes and T-lymphocytes. It includes the production of antibodies.
Vaccines are used to develop acquired immunity in people. The process is termed as vaccination or immunisation. Heat-killed or weakened pathogen or antigen is inserted into a person after which a person develops antibodies and memory cells against that pathogen or disease. So, the immune system acts more vigorously against that pathogen in secondary infection.
Thus, a person becomes immunised.
