Answer:
The insect pictured is in the order coleoptera
In ecology, allogenic succession is mediated by the abiotic components of the ecosystem, while the autogenic succession refers to the succession, which is mediated by the biotic components of an ecosystem.
A volcanic eruption wiping out an entire island is an example of allogenic succession.
A soybean crop helping in nitrogen fixation, leading to the development of other species is an illustration of autogenic succession.
A tsunami devastating all the living organism in a habitat is an example of allogenic succession.
Oak trees preventing the growth of smaller sun-seeking shrubs is an example of autogenic succession.
Answer: Characteristics of viral particles from the options given are;
1. Parasitic obligate.
2. The centre layer is predominate protein.
3.Genome may be RNA exclusively.
The characteristics of living cells are:
1 . May have cell wall.
2. Contain ribosomes.
3. Always of plasma.
Explanation:
Living cells are the basic unit of life, that contain the fundamental molecules in which the living things are composed of. Living cells have plasma membrane, ribosomes, cytoplasm and DNA.
Viral particle is a structure or infectious agents that enter another cell and replicates itself in a living cell. The are obligates parasite, that have no cell wall, they have center layer of protein, the genome contain either DNA or RNA, they reproduce only in living cells, they lack cytoplasm and organelles.
Answer: The answer is A) It aids the duplication and distribution of documents.
Explanation:
An intranet is a kind of website which can be used by any company but, internally. It means, it is a private web page, for this reason it is accesible just for people who have received authorization by the owners of this site. This is a good tool, because it allows the distribution and duplication of documents, programs or softwares in a short time. Also, thanks to this resource, time and costs can be reduced since people can access from different places. They can have meetings or send files and it does not matter where they are. As people can use intranet wherever, they can work and be more productive for the company.
Answer:
Method which is utilized by eukaryotes to control their gene expression that is different from the type of control found in bacteria is control of both RNA splicing and chromatin remodeling.
Explanation:
There is a difference in the gene expression of the prokaryotes and eukaryotes. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm, and gene regulation occurs at the transcriptional level. In eukaryotes gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm.
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes. A nuclear region that contains the DNA was formed. Transcription and translation were physically separated into two different cellular compartments. It therefore became possible to control gene expression by regulating transcription in the nucleus, and also by controlling the RNA levels and protein translation present outside the nucleus.
