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.

Question 1 Negative Forcings: increase the amount of sea ice at the north pole for instance. O increase the growing season. increases the amount of energy in the Earth's budget. decrease the amount of energy in Earth's energy budget.
Answer:
increases the amount of energy in the Earth's budget.
Explanation:
Increase occurs in the amount of sea ice at the north pole leads to increases the amount of energy in the Earth's budget because this sea ice reflects the solar radiation back to space. Sea ice has a bright surface which causes 80 percent of the solar radiation reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface which leads the ocean to absorbs 90 percent of the sunlight which heat up the oceans, and increase in the temperature occurs causes more melting of ice so increasing sea ice is good for the earth.

6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)
Answer:
Shivering and sweating.
Explanation:
A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body. Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.
Is it a good idea for humans colonize mars pls real answers :)
Answer:
I believe yes and no at the same time
Explanation:
If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?
Answer:
Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors
But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains
In conclusion, no it would not be a good idea.

What is tRNA?A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.
Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.
Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.
Therefore, The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.

Complete question:
The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K
TrueFalseAnswer:
TRUE
Explanation:
The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.
Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.
Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.
K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.
Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

In a good experimental design, the part of the experiment that is intentionally changed is the
A dependent variable.
B independent variable.
C constant
D control
Constants never change.
Controls typically don't change or they are done by standard means
(like in an experiment where you water plants with sodas, the plant you use water with is the control)
Dependent variables are the outcome of the experiment. This is the result of changing something.
Independent variables are what you are testing. A independent variable is something that is intentionally altered.
easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.

You transform a population of cells with a transgene and isolate a cell line that has integrated the gene into its genome, but in which the gene is not expressed. Speculate as to what may be preventing the gene from being expressed. Describe two ways to test this possibility.
Answer:
The transgene could be silenced by: 1- epigenetic mechanisms (e.g., DNA methylation, histone deacetylation, etc.), and 2-the RNA interference (RNAi) pathway
Explanation:
Epigenetics refers to the heritable changes caused by the activation and deactivation of genes without changing the DNA sequence. Epigenetic mechanisms include 1-DNA methylation on cytosine residues, and 2-modifications on amino acids in the tails of histone proteins (e.g., methylation, acetylation, ribosylation, phosphorylation, etc). These two epigenetic mechanisms can modify DNA structure and thus alter the accessibility of transcription factors, thereby suppressing gene/transgene expression. Moreover, the RNA interference pathway (RNAi) is a naturally occurring mechanism capable of suppressing gene/transgene expression both at transcriptional and post-transcriptional levels. The RNAi mechanism is triggered by regulatory non-coding RNAs (ncRNAs) such as, among others, long non-coding RNAs (lncRNAs) and small ncRNAs (e.g., miRNAs, piRNAs, siRNAs, etc). In this case, for example, DNA methylation on promoter sequences could suppress transgene expression, thereby methods to measure DNA methylation can be used to test this possibility (e.g., bisulfite genomic sequencing). Moreover, miRNAs that bind to the messenger RNA of the transgene could also inhibit its expression by triggering the RNAi pathway (e.g., mRNA degradation), thereby methods to measure mRNA levels can be used to test this possibility (e.g., RT-PCR).
