The correct answer is (a) The white salt crystals have a high albedo.
A substance appears white in color because it reflects most of the light falling on it. The term albedo shows that most of the sunlight falling on the particular area are reflected back leaving behind the salt of white color. Badwater Basin in Death valley is the hottest, driest and brightest area. Hence, the valley appears to be white in color because of the salt crystals that reflects back the maximum light falling on it.
Answer:
True
Explanation:
Cell cycle checkpoints are an important layer of control of the cell cycle. The cell cycle is a process by which cells divide.
There are 4 stages of the cell cycle G1, G2, S and M.
When the cell goes through the cell cycle, each stage has different processes that must occur for the cell to properly divide. During G1, the cell must grow to sufficient size and the environment must be favorable for cell division. During S phase, all the DNA must be properly replicated. during G2 the cell must prepare for division. During M, the cell actually divides.
There are 3 checkpoints throughout the cell cycle. The G1 checkpoint ensures the cell has reached sufficient size. The G2 checkpoint ensures the DNA has been properly replicated. The M checkpoint makes sure the chromosomes are properly attached to the spindles to split the DNA between 2 new cells.
Without these checkpoints, the cell can divide uncontrollably which can lead to cancer.
That is false. If all cells had the same function, then we would only be able to do one thing. Because of the diversity of the cells that we have, we are able to carry out many functions such as eating, drinking, moving, growing, blinking, etc. Hope I helped :)
Blood contains various diseases and fusing bloods that aren't the same type can cause various problems. If testing with blood it is unsure to know how much disease is in the blood.
