The natural succession of a small farm pond will tend to make the pond more likely to freeze solid in winter time,the nature of things helps them to merge more quickly and adapt to their environment.
Positive impacts of genetic engineering:
• New products are created such as food with higher nutrition values, drugs that are more effective and safer
• Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)
Negative impacts of genetic engineering:
• irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells
• abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.

Answer:
The correct option is <em><u>B. Eukarya only</u></em>
Explanation:
Bacteria can be described as prokaryotic organisms that do not possess a nucleus. Their genetic material is generally present in the cytoplasm of the cell in a region called nucleoid. Some extra genetic material is found in them in the form of plasmids. Hence, option D is not correct.
The domain, Archae, contains prokaryotes and they lack a nucleus. Hence, option A and C are not correct.
Eukaryotes are multicellular organisms which contain a nucleus and other membrane-bound organelles. Hence, option B is correct.
Answer:
Explanation:
The common characters shared by frogs and pigeons are:
presence of jaws
four limbs
The frogs and pigeons share these characteristics because they both are derived or evolved from a common ancestor.
During the course of evolution, the jaws are evolved in beaks in birds or pigeon as beak is light-weight in comparison to jaws.
Similarly, the forelimbs get covered with feathers to become wings.
