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 is option A. "They only introduce supercoiling and cannot relax a covalently closed circular DNA".
Explanation:
Type II topoisomerases are enzymes that regulate the winding an unwinding of DNA during DNA replication. Basically, these enzymes are the scissor that remove the knots and tangles formed during the replication process. Is false to affirm that type II topoisomerases only introduce supercoiling and cannot relax a covalently closed circular DNA. Bacterial type II DNA topoisomerases work with the circular DNA of bacterium by changing the linking number of circular DNA by ±2.
Clean Air Act (CAA), US Federal law, passed in 1970 and later amended, to prevent air pollution and thereby protect the ozone layer and and promote public health. The clean air act gave the federal environmental protection agency the power it needed to take effective action to fight environmental pollution. Hope this helps シ
D bc active transport is basically the opposite of osmosis and diffusion
DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
