The question is incomplete as it misses the options which are:

Cancer cells do not exhibit density dependent inhibition

Cancer cells do not require growth factors

Cancer cells do not exhibit anchorage dependence

Cancer cells ignore typical cell cycle checkpoints

Answer:

The correct answer will be option- Cancer cells do not exhibit anchorage dependence

Explanation:

A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.

As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.

Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.

Thus, the cancerous cells lack the anchorage dependence

Answer:

A. inheritance and reproduction

Explanation:

These two terms are interrelated as the act of one (reproduction) gives rise to the other (inheritance). The process whereby offsprings are produced using gametes (sexual reproduction) or without gametes (asexual reproduction) from a an organism called the parent is called REPRODUCTION. Reproduction is necessary to ensure the survival of a particular species.

During reproduction, the genetic material (DNA) in form of chromosomes of an organism is passed down from parents to offsprings in a process called INHERITANCE or HEREDITY. The information needed for certain processes like growth, reproduction, survival and others are contained in the genetic material, and are transferred from the parents to their progenies.

In sexual reproduction, this biological information encoded in the genetic material is passed on via gametes produced by each parent (male and female) during meiosis.
