<h2>Answer:</h2>

<u>Bases</u> are the chemical compounds which give out \bold{OH^-} ions when dissolved in aqueous solution or water.

<h2>Explanation:</h2>

In science, bases are substances that show the following characteristic:

  • In watery arrangement, discharge hydroxide \bold{(OH^-)} particles.
  • It is elusive/slippery to the touch.
  • It has bitter taste.
  • It changes the shade of litmus paper (e.g., turn red litmus paper blue).
  • It responds with acids to shape salts.
  • It advances certain compound responses (base catalysis).
  • It receives protons from any proton contributor or contain totally or halfway displaceable OH^- particles.

vodka [1.7K]

Answer:

Denatured (unfolded) proteins do not function normally.

Explanation:

Proteins are the polymers made of the alpha amino acids that are linked through the peptide bond. Protein is one of the most important biomolecule acts as the main building block of the body.

Protein are specific in functions and works only when they have correct three dimensional structure. The denaturation of protein causes the change in its structure, makes the protein less folded and the protein is unable to perform its function after the denaturation.

Thus, the correct answer is option (2).

what introduced species on macquarie island were most responsible for severely degrading the local biological communities, inclu
RideAnS [48]

The culprits for the degradation of local biological communities on Macquarie Island are the rabbits, rats,mice and cats that were non-native species were introduced by humans.

The introduction of non-native species to Macquarie Island was responsible for severely degrading the local biological communities, including the vegetation, birds, and invertebrates that were native to the island. The introduction of rabbits, rats, cats and mice led to the loss of native plants, while cats and pigs preyed on native birds and invertebrates. These introduced species caused extensive damage to the local ecosystem, resulting in the loss of native species and the decline of the island's biological diversity.

The new species competed for resources and habitat, and often preyed upon the native species. This had a devastating impact on the local ecosystem, and led to the decline of many native species. The introduction of rabbits was particularly damaging, as they caused widespread destruction of the native vegetation. This had a knock-on effect on the birds and invertebrates that depended on that vegetation for food and shelter. The decline of the native species has had a significant impact on the biodiversity of Macquarie Island, and has resulted in the loss of many unique and valuable species.

These species have wreaked havoc on the island, preying on native birds and other small animals, as well as destroying vegetation. The impact of these introduced species has been so severe that the island has been declared a World Heritage Site. In order to protect the remaining native species on the island, a eradication program was launched in the 1990s to get rid of the introduced animals. While this program has been successful in reducing the populations of these animals, they continue to pose a threat to the island's ecosystem.
