I think that the answer is D. The cell employs the G2 checkpoint to check for DNA damage and completeness of DNA replication. This is done to ensure that cell division runs smoothly which means that healthy daughter cells, with complete and undamaged DNA, will be produced. At this point, all necessary repairs are applied.
Answer:
The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.
The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.
All cells have a protective covering known as cell membrane. In plants, the cell membrane is further protected by another layer called cell wall. All the organelles present inside the cells are membrane bounded structure.
Cell membranes are made up of phospholipid bilayer with extrinsic and intrinsic proteins. From the studies on the plasma membrane structure, it was found that the protein fingerprint of MITOCHONDRIA and CHLOROPLAST are most similar to the cell membrane.
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
<span>The Iroquois constitution is a document known as the "Great Binding Law", also known as the "Great Law of Peace." He law is best described as a tree. The tree is then used to Interpret the law, by using the many uses of the tree in metaphors. The shade, roots and leaves all signify certain aspects of the law, explains how the tree can represent peace among the 5 nations.</span>
