Answer:
As the size of a star increases, luminosity increases. As a star’s temperature increases, its luminosity increases.
The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space.
Answer:
The statements that describe how the trans bilayer asymmetry in the lipid bilayer is achieved and maintained are listed below.
Explanation:
Phospholipids in the plasma membrane are anchored to a specific location in the plasma membrane via strong hydrophobic interactions with neighbouring lipids thus maintaining the asymmetrical distribution of lipids in the bilayer.
Specific phospholipids in the plasma membrane covalently attach to certain integral membrane proteins.These covalent interaction anchor the phospholipid to specific location in the plasma membrane and maintain the asymmetrical distribution of lipids in the bilayer.
<span>When the dna pieces called telomeres get too short, the cell can no longer divide.
</span>We can define Telomeres as they<span> are the caps that are present at the end of each strand of DNA and there function is also that they protect our chromosomes, when they get too short the cell can no longer divide these dna pieces and they die.</span>
Polar PERIPHERAL MEMBRANE PROTEINS are typically found attached to the outside of a membrane.
The membrane is majorly made up of phospholipids, which are bilayer in nature, having a polar head and a non polar tail. There are two types of membrane proteins; the integral and the peripheral protein. The peripheral protein is usually found on the outside of the membrane, attached to the polar head of the phospholipid bilayer.
