Answer:
cell transport or membrane transport helps in the transport of solute molecules and ion across the plasma membrane and helps in maintaining homeostasis of these molecules in the biological system.
Explanation:
Homeostasis is very very important to maintain a steady body physiology and the maintenance of steady body physiology is highly significant because any type of disturbance in the homeostasis can leads various physiological abnormalities.
Various membrane transport process such as osmosis helps in the movement of water from high concentration region to the region of low water concentration until equilibrium is reached.Thus osmosis helps to maintain water homeostasis in our body.
By the same way glucose transporter maintain the homeostasis of glucose inside our body.
Answer:
The correct answer will be option- <em>Streptococcus pyogenes.</em>
Explanation:
M protein is an important virulence factor which is produced and expressed on the surface of <em>Streptococcus pyogenes.
</em>
This protein plays important role in the bacterial infection like adherence to epidermal keratinocytes, resistance to phagocytosis, invasion of epithelial cells and microcolony formation.
The M-protein is a α-helical coiled structure protein which consists of the four distinct regions (A–D) in which A-region in the N-terminal is highly variable.
Thus, option- <em>Streptococcus pyogenes</em> is the correct answer.
D. Chloroplast is only found in plant cells not in animal cells
Answer: B. under use; it is a scarce resource.
Explanation:
Early settlers in the town of Dry Gulch drilled wells to pump as much water as they wanted from the single aquifer beneath the town. (An aquifer is an underground body of water.) As more people settled in Dry Gulch, the aquifer level fell and new wells had to be drilled deeper at higher cost.Residents of Dry Gulch have a private incentive to under use water because it is a scarce resource.
