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.

Which dna mutations is most likely to damage the protein it specifies?

Radda [10]

<h2>DNA Mutations</h2>

Explanation:

(A) A base-pair deletion

Insertion or deletion brings about a frame shift that changes the perusing of consequent codons and, hence, adjusts the whole amino acid arrangement that follows the transformation, additions and cancellations are normally more harmful than a substitution in which just a solitary amino corrosive is modified
DNA changes brought about by mutagens may hurt cells and cause certain illnesses, for example, malignancy
Instances of mutagens incorporate radioactive substances, x-beams, bright radiation, and certain synthetic compounds

The graph below shows ocean data relating to climate change. Explain why both the atmospheric and seawater carbon dioxide levels

rosijanka [135]

A. Carbon dioxide levels are increasing in the air, and the ocean is absorbing carbon dioxide; atmospheric levels are increasing so much that the increase is still apparent even with increasing absorption of carbon dioxide by the ocean. Research conducted by the University of Miami (UM) has found that the waters of the North Atlantic absorbed 50 percent more carbon dioxide of human origin in the last ten years than in the past decade.
The results of the study show the impact that the burning of fossil fuels has had on the world's oceans in the last ten years
