The answer is 62 percent. <span>By 1999, after the Clean Water Act had been passed in 1970, the percentage of U.S. surface waters safe for fishing and swimming had increased from 36 percent to 62 percent. </span>
Lipids differ from other large biological molecules in that they are not truly polymers ; Lipids are not all made of the same type of monomer. Their association as a group is related to their behavior rather than their structure.
Answer:
<h3> definition of binomial nomenclature</h3><h3>a system of nomenclature in which each species of animal or plant receive a name of two terms of which the first identifies the genus to which it belongs in the second of the species itself</h3>
Answer:
1. When the beginning of Earth occurred, there was little to no oxygen. So, some cells had to adapt to this and the process of anaerobic respiration allowed them to do so. In the grand scheme of things, there must have been a great number of anaerobic respiration occurring given the clement.
2. That probably would have caused the
atmosphere to cool down dramatically. The
cyanbacteria could have assisted, because it puts
oxygen into the atmosphere. The other autotrophs
would be affected, because if the temperature
dropped, the air would have cooled down.
Then, the autotrophs would not have
food from the carbon dioxide, or
other inorganic materials.
Explanation:
p16 is a tumour suppressor protein that functions as a cyclin-dependent kinase inhibitor and is required for cell cycle regulation. Because p16 inhibits cyclin-dependent kinases that phosphorylate Rb, it can slow down the cell cycle.
<h3>Tumor suppressor genes encode which type?</h3>
Tumor suppressor genes, also known as anti-oncogenes, encode proteins that transduce negative cell growth regulatory signals such cell cycle arrest and death.
The TP53 gene codes for the production of a protein known as tumour protein p53 (or p53). This protein functions as a tumour suppressor, which means it controls cell division by preventing cells from growing and dividing (proliferating) too quickly or uncontrollably.
Cyclins and cyclin-dependent kinases are two types of proteins that promote the cell cycle.
