The name given to the original cell before it divides is called the parent cell.
Answer:
ubiquitin targets CDKs
Explanation:
Cyclins are named such because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex. This complex then acts as a signal to the cell to pass to the next cell cycle phase.
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
Due to human activities, the greenhouse gases are the most substantial mediator of the witnessed climate change since the mid-20th century. Globally, the overall emissions of greenhouse gases due to human activities have upsurged by 35 % from 1990 to 2010.
The concentrations of carbon dioxide and other greenhouse gases in the atmosphere have upsurged since the start of the industrial revolution. Of the greenhouse gases, the fluorinated gases exhibit an average lifetime in the atmosphere of a few weeks to thousands of years.
The fluorinated gases refer to an array of gases, which comprise fluorine, incorporating perfluorocarbons, hydrofluorocarbons, and sulfur hexafluoride, among other chemicals.
These gases are discharged due to numerous industrial procedures and household and commercial applications and do not take place naturally. It is at certain instances used as the substitutes for the ozone-depleting components like CFCs.
Answer:
Blood cells are a lot smaller than nerve cells and have a disc-shaped structure, both great traits for moving quickly through small spaces. Their disc shape also provides them with a big surface where lots of oxygen can enter the cell.
