Okay I am good with it’s not like the mice
The answer is; DNA helicase
They unzip the double helix into single strands during replication. The unzipping occurs at regions called origins where replication is initiated. The protein breaks the hydrogen bonds (using energy from ATP) between the complimentary bases of the strands hence forming a replication fork.
Answer:
with each heartbeat,the heart pumps blood throughout our bodies,carrying oxygen to every cell,after delivering oxygen the blood returns to the heart the heart then sends the blood to the lungs to pick up more oxygen.
As when things get eaten some of the energy is lost the predators have to have more than one prey to survive, this means there is only a limited amount to be shared which means less predators
Ans.
Hormones are regulatory substances synthesized by various plants and animals and play role in proper growth, development, and maintain homeostasis. Hormones are released by signalling cells and show their actions after binding to specific receptors present on the surface or inside of the target cell.
Hormones, for which receptors are present inside the cells (in cytosol or nucleus) should be hydrophobic in nature. This is because plasma membrane is made up lipid molecules and small, hydrophobic, uncharged molecules can easily pass through this. For example, cortisol, estrogen, and progesterone hormones are lipid-derivatives and receptors for these hormones are present inside the cells.
