The nucleus contains chromosomes that contain the DNA molecules and in these DNA molecules, genes are found that are responsible for the passing of characters from the parents to the children. Hence, nucleus is your answer.
Hope my explanation helps !
Answer:
cleavage of MIC at the cell surface by a protease
Explanation:
The immune system refers to a complex network of cells and proteins that function to eliminate potentially tumorigenic cells on a daily basis. However, cancer cells show mechanisms in order to escape immune responses. MHC class I chain-related proteins A and B (MICA and MICB) are expressed in normal and tumorigenic cells where they act as ligands of the NKG2D receptor. The expression level of these proteins (MICA and MICB) is finely regulated by the activity of metalloproteinases (i.e., by protease-mediated cleavage), but this mechanism is altered in cancer cells. Recently, drug therapies that stimulate NKG2D mediated tumor destruction by reducing the cleavage of MICA and MICB from the surface of cancer cells have been developed.
Answer:
It allows ice to float to the top of water, insulating water below allowing life to live. It allows ice to sink to the bottom of water, allowing life to live above
Explanation:
D. Comparative
They are collecting data on two different organisms to compare and contrast
I would calmly check the breaker panel to verify that the power hadn't simply gone off again. I'd troubleshoot back to the pump, then its suction pipe from the well, then peek at the water level in the well. If the well had run dry, I'd - still calmly - step into my shop and take the stainless-steel buckets down from the high shelf above the Porter-Cable routers and walk across the road with them. I'd step over the guardrail, then walk down the embankment to the Waits River, where I'd fill my buckets and bring them - full - back to the house.
