if a single-celled organism is unable to undergo cell division, which of its life functions is affected?
castortr0y [4]

Answer:

The correct answer would be reproduction.

Single-celled organisms usually reproduce asexually with the help of cell division.

Asexual reproduction is a type of reproduction which takes place without the fusion of gametes and hence required only one parent.

Various types of asexual reproduction are fission (binary or multiple), budding, fragmentation, vegetative propagation etc.

Unicellular organism usually divide by fission either binary or multiple.

In binary fission, a parent cell divide into two equal sized daughter cells such as observed in bacteria.

In multiple fission, a parent cell divides into multiple daughter cells as observed in multiple fission of sporozoans etc. During this, parental nucleus divides several times with the help of mitosis without cytokinesis which produces several nuclei within a parent cell. The cytokinesis then takes place which results in separation and production of multiple daughter cells.

Give one example of a bad mutation and one example of a good mutation.!
topjm [15]

Answer:

Bad mutation: deletion/addition mutation

Good mutation: silent mutation

Explanation:

Addition or deletion mutation results in the reading frame of codons to be changed, leading to a extensive missense mutation that will lead to a non-functional protein product to form.

Good mutation are silent mutations that leads to no change to the final product but causes codons to change in sequence. This increases genetic diversity in the gene pool that enables the species to be more resilient to environmental changes.
