Leona [35]

One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C).

<h3>What are cancer cells?</h3>

Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.

When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively.

Normal cells are characterized by their ability to regulate cell division during the cell cycle.

Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.

just olya [345]

Answer:

1. fragmentation- genetically identical

2. budding- genetically identical

3. haploid cells from two different mycelia fuse to form a zygote- genetically distinct

4. one hyphae creates spores through mitosis- genetically identical

Explanation:

1) Fragmentation is a form of asexual reproduction i.e. one parent, employed by certain organisms including fungi in which a FRAGMENT breaks off from the single parent to produce new cells. Since it is an asexual reproduction, the resulting cells will be GENETICALLY IDENTICAL.

2) Budding is another form of asexual reproduction that fungi undergoes e.g yeast. In the budding process, buds develop on the parent cell and later grow into mature cells that are GENETICALLY IDENTICAL to the parent cell.

3) In fungi, two different mycelia can produce haploid sex cells via the process of meiosis, which then fuse to produce a ZYGOTE. This method is a sexual means of reproduction. Hence, the zygote formed will be GENETICALLY DISTINCT from the parent.

4) Hyphae (threadlike filaments) of a fungi can via MITOTIC DIVISION produce spores, which then germinates under favorable conditions and grows into a new fungus. This new fungus cell is GENETICALLY IDENTICAL to the parent hyphae.
