Explanation

Mitosis is a type of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell, producing somatic cells (body cells).

It is responsible for:

• growth
• repair
• asexual reproduction in organisms.
  

Explanation

Scorpions and spiders both belong to the class Arachnida.

This class includes arachnids, which are characterized by having eight legs and lacking antennae.

Explanation

Explanation

Parasitism is a type of relationship where one organism (the parasite) lives on or inside another organism (the host)

And benefits at the expense of the host, who is harmed by the interaction. 

Explanation

It is estimated that about 99.9% of all species that have ever existed on Earth are now extinct.

This figure underscores the vast extent of extinction events throughout:

• Earth's history
• reflects the dynamic 
• often unstable nature of life on the planet.

The remaining 0.1% of species are the ones that are still extant today.

Explanation

Adaptive radiation is the process by which a single ancestral species rapidly diversify into a wide variety of forms to adapt to different environments or ecological niches.

This typically occurs when a species colonizes a new habitat or experiences a significant environmental change. 

Explanation

Divergent evolution occurs when two species that share a common ancestor evolve different traits or characteristics over time due to adapting to different environments or ecological niches.

This process leads to increased differences between the species.

Explanation

The notochord is a flexible, rod-shaped structure that is present during the embryonic stage of all chordates

It provides support and defines the primitive axis of the body.

This characteristic is a key feature that distinguishes chordates from non-chordates.

Explanation

In the taxonomic hierarchy, the rank that comes directly below the class is the order.

The full hierarchy from broader to more specific categories is:

1. Domain
2. Kingdom
3. Phylum
4. Class
5. Order
6. Family
7. Genus
8. Species.

Explanation

The phenotype refers to the observable physical characteristics or traits of an organism, such as:

• height
• eye color
• skin texture.
