In an electron cloud, an electron that is farther away from the nucleus has. a greater charge than an electron near the nucleus. a smaller charge than an electron near the nucleus. a higher energy than an electron near the nucleus.
Answer:
Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle
Explanation:
The term cell cycle refers to the mechanism of DNA replication and cell division, which involves a series of sequential steps. The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events. HeLa is an immortalized cell line derived from cervical cancer cells. These cells (HeLa) contain 76 to 80 total chromosomes (instead of the 46 chromosomes that contain normal-diploid body cells), some of which are heavily mutated. These mutations can affect CDKs that control the cell cycle as well as checkpoint-control mechanisms (for example, those resulting from DNA damage), thereby cells do not enter programmed cell death (apoptosis) and proliferate uncontrollably.
Dna holds information for the cells that make up an offsprings body and traits. A parents' genes will pass on this way.
Molten Lava, and not solid like the crust.
Normally tree rings will disappear, damage, or go missing when the tree doesn't have enough nutrients, another factor that contributes to that is drought.
