Let's see which option fits with each characteristic.
Multicellular, or having more than one cell, could be any of these Kingdoms. These are all eukaryotic kingdoms, and eukaryotes cannot be unicellular.
Heterotrophic, or something that cannot produce its own food, can be all of these except Plantae, plants of this kingdom are autotrophic, as they mainly produce their own food (think photosynthesis).
Having a cell wall applies to all of these except Animalia. Animal cells don't need cell walls, as they don't require such a rigid structure as plants. Animals will typically have other supporting structures, such as bones or hydrostatic skeletons.
Being unable to move applies to all of these Kingdoms except Animalia and Protista (which move using their cilia or flagella). Plantae and Fungi don't have the means to move by themselves.
So, the only kingdom that has not been ruled out by one of the criteria is Kingdom Fungi !
When an oncogene is turned on and is not balanced through suppression
of tumor suppressor gene, the normal
cells become cancerous and divides unregulated.
Normal cells differentiate while cancer cells do not. Additionally,
while normal cells respond to endocrine
and paracrine signals from neighboring cells, cancer
cells do not. Cancer cells have malfunctioned
apoptosis process due to a malfunctioned p53
tumor suppressor gene. Therefore they
continue to divide even when they have damage to their DNA. Cancer cells metastasize because, unlike normal cells, they do not produce an adhesive molecule that allows the cells to adhere to one another to form tissue.
Hey friend!
Let's figure this out!
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule. DNA replication is self-complementary, and it does not need a third party. The two strands of a DNA act as parents and work as a template to synthesize the two daughters of DNA. According to an estimate, there are nearly 3 billion DNA bases in our genome, and during DNA replication they all replicate. Mutation can cause changes in DNA bases only, but it can be one or even more than one basis.<span>

mitosis is 2 identical cells (Diploid)
meiosis is 4 s3x cells (Haploid)
