Answer:

yea your paragraph is good!!!

Explanation:

<u><em>Asexual</em></u>

Before a cell divides, its nucleus divides. Each chromosome is copied, and each nucleus receives the same genetic material: genes, made of DNA.

As each cell divides into two, the resulting "daughter" cells are therefore exact copies of one another.

<u><em>Sexual</em></u>

Both male and female sex cells (sperms and eggs in animals, pollen and ovules in plants) are produced by a special cell division process which halves the number of chromosomes in each resulting cell. The chromosome separation process ensures that each sex cell has a unique combination of genes in its nucleus.

Fertilisation is also a random process and so when the nuclei fuse the resulting fertilised egg (zygote) has an individual genetic makeup.

In contrast to asexual reproduction, sexual reproduction introduces variation into offspring. This is an essential feature in order for evolution to take place.

Name two examples of catastrophic events which could lead to a mass extinction?
Lemur [1.5K]

Asteroid impact

Volcanic eruptions

Explanation:

Asteroid impact and volcanic eruptions are two common events that could lead to a mass extinction.

A mass extinction is an abrupt decrease in life on earth due some catastrophic event.

  • The collision of a large bolide on the surface of the earth is a catastrophe in itself.
  • The collision and its aftermath have destructive consequences on life.
  • The force of the collision can reverberate in form of vibration throughout the earth.
  • It can cause heating of the earth surface.
  • Volcanic eruptions can become global phenomenon that upsets the earth balance.

Which of the following could be found on either public or private land?
Reptile [31]
<span>The option that could be found on either public or private land is C. mine. A state park can only be found on public land, because parks are owned by states, not regular people. A single-family residence is only found on private land, because that is a house that a family owns. A factory is on private land only, because it belongs to a person or another company. Which leaves us with mines, that can be found both on private and public lands.</span>
