Answer:

Direct.

Explanation:

An information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Hence, an information system interacts with the overall system by receiving data in its raw forms and information in a usable format.

In this scenario, Mother Goose Computing, Inc. are currently updating several of their systems. For the genomics division, it's planning to replace the old system by the new one all at once. Thus, this is called a direct conversion.

Direct conversion can be defined as a process which typically involves the establishment and implementation of a new system followed by an immediate discontinuation of the old system all at once. Thus, on a particular date and time, the old system would be discontinued while the new system is immediately adopted for use in the particular organization.

bacteria with No Plasmid -----------------will grow ONLY in medium without ampicillin.

"nonrecombinant gene, recombinant plasmid with vgp gene,", recombinant plasmid but no vgp gene-----------------------will grow in both media".

it means Plasmid have ampicillin resistance gene. So if we use medium with ampicillin so it will allow the growth of only those bacterai which have transformed plasmid (containing amp resistance gene).

 so having gene or not, recombinant or recombinant dosnt matter,  all the other s will grow in both type of medium as far as plasmid is transformed in to it.

How do the directions to make a protein get from the nucleus to the cytoplasm?
Margaret [11]
The mRNA made from the section of DNA coding for the protein (the gene) exits the nucleus through a nuclear pore after getting modified. It can get modified by getting a poly-A tail and a methylated cap, along with removing the interfering sequences (introns).

How does a new mammoth egg cell get chromosomes from each of the parents?
nikitadnepr [17]

Answer:

An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father's sperm and one came from the mother's egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.
