Answer:
8
Explanation:
Hydrogen has 1 Valence electron, and H2O has 2 Hydrogen. Oxygen has 6 Valence electrons so do 2+6 = 8. 8 Valence electrons! (Or one full shell not consisting of the first shell.)
Answer:Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle.
Explanation:
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.
Answer:
your answer it is help to understand this question
The correct option is D.
Transcription is the process by which the information in a DNA molecule is copied into an mRNA strand. Replication is the process by which two new strands of DNA are formed from a single parent DNA. Both the DNA and the RNA are composed of four different bases, three of the bases are the same while one is different for the DNA and RNA. It is only the RNA that has uracil while it is only the DNA that has thymine. Thus, Uracil is involved during the process of transcription since it is an mRNA strand that is formed while thymine is the one involved during the process of replication since it is a DNA molecule that is formed.<span />
