Explanation

• The sentence should read: "The new findings on the virus caused panic among the scientists and management alike."
• The word "alike" is used to indicate that both scientists and management shared a similar reaction (panic) to the new findings.

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.
  

Explanation

Gap junctions are specialized structures that allow direct communication between adjacent cells.

They are formed by connexin proteins that create channels enabling the exchange of ions, metabolites, and other small molecules between cells. 

Explanation

Sharks, along with other cartilaginous fish-like rays, retain urea in their bodies as part of their osmoregulatory strategy.

This helps them maintain osmotic balance in marine environments by making their internal body fluids isotonic with the surrounding seawater.
