Hydra is a multicellular organism, while the others are unicellular.

Flaxseed oil is a rich natural source of omega-3 fatty acids, beneficial for heart health.

Viruses are non-cellular entities that require a host cell to replicate.

Diabetes is classified as a non-communicable disease.

Pine trees are gymnosperms and are considered non-flowering plants as they do not produce flowers.

Water is a non-living component of an ecosystem, while plants, animals, and bacteria are living components.

Water is a non-living component of the ecosystem, while plants, animals, and bacteria are living components.

Mosses are non-vascular plants, meaning they do not have specialized tissues for transporting water and nutrients.

Boron is a trivalent element that creates holes in silicon, making it a p-type semiconductor.

Tubal ligation is a surgical procedure that permanently prevents pregnancy by blocking the fallopian tubes.

Hybrid inviability is a postzygotic barrier that occurs when hybrid offspring do not develop properly or die before reaching reproductive maturity.

Biotechnology has various applications in agriculture, including the development of pest-resistant crops, production of biofuels, and creation of synthetic hormones.

One potential risk of genetically modified crops is the development of resistant pests, which can lead to increased agricultural challenges.

One potential risk is the development of resistant pests, which can lead to increased pesticide use.

A potential risk associated with the use of GMOs is the development of resistant pests, which can lead to increased pesticide use.

Electric generators utilize electromagnetic induction to convert mechanical energy into electrical energy.

Phloem is responsible for the transport of food, primarily in the form of sucrose, from the leaves to other parts of the plant.

Primary producers, such as plants, convert solar energy into chemical energy through photosynthesis.

Bt cotton is a genetically modified organism (GMO) that has been engineered to express a bacterial toxin, making it resistant to certain pests.

Microbial fermentation can produce antibiotics, vitamins, and alcohol, among other products.

Bacterial cells are prokaryotic, meaning they lack a defined nucleus and membrane-bound organelles.

Bacteria are prokaryotic organisms, which means they lack a defined nucleus and membrane-bound organelles.

All actinides are radioactive, with many being synthetic and unstable.

Addition polymers are formed from unsaturated monomers through addition reactions.

Aldehydes are generally more reactive than ketones due to the presence of the hydrogen atom attached to the carbonyl carbon.

Amorphous solids are isotropic, meaning their properties are the same in all directions, unlike crystalline solids.

Covalent network solids, such as diamond, have very high melting points due to the strong covalent bonds throughout the structure.

Electric field lines cannot intersect because it would imply two different directions of the electric field at a point.

Ethers are generally flammable due to their hydrocarbon nature, although they have moderate boiling points.

Intrinsic semiconductors are in their pure form without any doping.
