Rabbits, turtles, fish, humans, and whales all share certain characteristics but also differ from each other. All of these speci

Delvig [45]

The levels of organisation are

Domain: Eukarya

Kingdom Animalia

Phylum :Chordata

Explanation:

They all share these levels of organisation because;

for the Domain Eukarya, they have;

→multi-cellular cells containing nucleus; and other membrane bound organelle.e.g Mitochondrial.

→their DNA located in the nucleus packaged as linear chromosomes bounded by histone proteins.

→mode of reproduction which is sexual.

They share Kingdom Animalia because;

→they have multi-cellular, specialised cells, bounded by plasma membranes.

→they have specialized tissues, organs, and system.

→they all undergo heterotrophic mode of nutrition as evident in the question 'that they must consume plants and animals as source of energy'

→they exchanged communication by nervous ssytem and 

→ use homeostatic mechanisms to regulate water balance of the body through the kidney.

→Humans,Rabbits,and whales are VIVIPAROUS; they give birth to young ones alive.

→Most fishes lay eggs to reproduce, they are said to be Ovoviviparous.

They belong to phylum Chordata because ;

→they all have noto chord; which serve as template for axial skeleton.

dorsal hollow nerve cord -template for the brain and spinal cord

→pharyngeal slits- templates for gill aches in bony fishes and components of inner ear in land animals.

→ tail length varies in these organisms.

10. What do we call the action when one muscle works against another muscle?

Kisachek [45]

<h2>Answer:</h2>

Antagonistic.

<h2>Explanation:</h2>

Muscles generally work in groups or pairs.
Muscles are connected to bones via tendons, these tendons and muscles help in movement of a joint.
When a muscle is put in contraction, usually only one bone moves. For example on contraction of biceps of the arm contracts then the radius moves but the scapula does not move.
This type of muscle action is called antagonistic muscle action. In which the muscle which is working is called the prime mover or agonist and the relaxing muscle is called the antagonist.

Result: The muscle action in which a muscle works against another muscle is called antagonistic.
