The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.
i would go with true.
Answer: silent mutation: a nucleotide base in a codon is replaced with a different base BUT the resulting amino acid isn’t affected.
Missense mutation: similar to a silent mutation, the only difference is that the switch of the nucleotide DOES result in a DIFFERENT amino acid
Nonsense mutation: a nucleotide base is changed, but that change results in a premature stop of translation
(Remember that after transcription, you are left with a strand of mRNA that Is then translated into a protein. The mRNA is read in increments of three nucleotide bases (A,U,G, or C) which is called a codon. That codon makes a single amino acid, and a strand of amino acids makes a protein)
The answer is C DNA and that is the answer
Options for the question have not been provided. They are as follows:
A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.
B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.
C) The separate 1-hectare plots are less vulnerable to edge effects.
D) The large plot will create more inbreeding in many species.
Answer:
A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.
Explanation:
In the given case, 20 hectares of land has been allocated to natural habitat. This means that natural flora and fauna will flourish here without any human interference. In this situation it is better to have an intact 20 hectares area at one side of the land, rather than having 20 separately spread out 1 hectare areas. This is because having one large piece of land at one side will reduce the edge effect.
Edges occur where two different habitats meet. While edges can be beneficial when it comes to natural habitats because the boundary habitat increases overall biodiversity, it can be detrimental when the edges are due to human settlements. It will be difficult to avoid human interference as the natural habitats are scattered among human settlements. Each individual plot will also get less area due to which it will be difficult for all the species to accommodate comfortably. Many animals can venture out in search of food which can be dangerous to both animals and humans. It is better to have a big separate land at one corner so that everyone can survive peacefully.
