Based on this diagram label the positive and negative sides of the DNA fingerprint with a + and – sign.
We can say that the top of the gel, where the DNA samples were applied, is the negative side, while the bottom of the gel is the positive side.
We can arrive at this answer because:
DNA is a negatively charged molecule.For this reason, when DNA is applied in an electrophoresis vat, it must be placed in the negatively charged portion.This is because the electrophoresis vat will allow an electrical discharge to pass through the vat and drag the DNA from the negative side to the positive side.This movement allows the DNA to present a series of fragments of different sizes that will be observed in a fingerprint, such as the one presented in the question above.
In the figure below you can more accurately see the positive and negative sides.

If the environment gets cold, humans will often respond involuntarily by shivering in order to:
a. keep body temperature the same as the external temperature
b. increase body temperature
C. decrease body temperature
d. regulate blood pressure
Answer:
increases body temperature
Explanation:
this is because when you shiver your blood vessels contract which then increases your body temperature
If the environment gets cold, humans will often respond involuntarily by shivering in order to increase body temperature. So, the correct option is B.
What do you mean by Environment?An environment may be defined as anything that is present in the surroundings of living entities that is either biotic or abiotic.
The process of shivering causes the blood vessels to contract and relax at a rapid rate to maintain homeostasis. The signals of rapid contractions are sent by the hypothalamus through nerve impulses.
Therefore, the correct option for this question is B.

Axons from higher brain centers form motor tracts that descend from the brain into the white matter of the spinal cord and then synapse with somatic motor neurons in the ____________.
Motor output that is gotten from the spinal cord to skeletal muscles involves somatic motor neurons of the anterior gray horn. Many somatic motor neurons are regulated by the brain. Axons from higher brain centers form motor tracts that descend from the brain into white matter of spinal cord and then synapse with somatic motor neurons either directly or indirectly by first synapsing with interneurons that in turn synapse with somatic motor neurons.
Sensory receptors is known to detect sensory stimulus.
Sensory neurons often convey sensory input by nerve impulses through their axons. Their axon often start from sensory receptors into the spinal nerve and into posterior root.
From posterior root, axons of sensory neurons have 3 different choices of paths.
Axons of sensory neurons does start into the white matter of the spinal cord and moves up to brain as part of sensory tract.Axons of sensory neurons sometimes do moves into the posterior gray horn and synapse with interneurons that has its axons extend into the white mater of spinal cord and thereafter moves to brain as sensory tract.Axons of sensory neurons oftens moves into the posterior gray horn and synapse with interneurons which the synapse with somatic motor neurons.Axons that is gotten from spinal cord often synapse with other motor neurons in PNS.

what is the dominant impact that humans have on alpine glaciers?
The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.
Answer:
Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

Which of the following has the greatest effect on the protein molecule produced
by a ribosome?*
A. The sugars in the RNA molecule
B. The nitrogenous bases in DNA
C. The hydrogen bonds in the tRNA
D. The phospholipids in the cell membrane
Answer:
The answer is B.
Explanation:
Depending on what order the nitrogen bases are used in the DNA will determine the opposite bases placed on the RNA making the sequence different, making the protein different.
The nitrogenous bases in DNA has the greatest effect on the protein molecule produced by a ribosome. Thus, option B is correct.
What are the nitrogenous bases in mRNA?Nitrogenous bases in mRNA are the sequence of amino acids. The translation is one of the two-stage events in protein synthesis. Protein synthesis is the process in which protein or polypeptide chains are synthesized by the DNA. This is the use of nitrogenous bases in mRNA.
The process of translation is similar to a smartphone app converts spoken English into Spanish as it involves the translation of the sequence of nitrogenous bases in mRNA molecules to the polypeptide or sequence of the amino acids.
Protein has been defined as the large macromolecules and biomolecules that are made up of long chains of amino acid. There has various function of protein such as DNA replication, speeding up chemical reaction, and helps to maintain the structure of cell.

How many minutes are there in a 40-hour week?
A:2,000
B:2,400
C:1,400
D:1,200
There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.
What is Unit conversion?
Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.
Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).
The week of 40 hours can be converted into minutes by:
Number of minutes in 1 hour = 60
Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes
Therefore, the correct option is B.
