Answer:

The underlying principle of SEC is that particles of different sizes elute (filter) through a stationary phase at different rates. This results in the separation of a solution of particles based on size.

hope it helped

Size exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel.

Size exclusion chromatography (SEC) splits molecules based on their size by filtration via a gel. The gel consists of spherical beads including pores of specific size distribution. Separation happens when molecules of various sizes exist included or excluded from the pores within the matrix.

Size exclusion chromatography exists named gel filtration chromatography because the gel effectively allows for the filtering of molecules from a sample based on molecular size. However, unlike other methods, the larger molecules elute first.

Size-exclusion chromatography (SEC), also understood as molecular sieve chromatography, exists a chromatographic procedure in which molecules in solution exist separated by their size, and in some cases molecular weight. It exists usually applied to large molecules or macro molecular complexes such as proteins and industrial polymers.

When fossil fuels exist burned, they release large quantities of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, pushing global warming.

Fossil fuels exist created from decomposing plants and animals. These fuels exist found in the Earth's crust and include carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas exist examples of fossil fuels.

A fossil fuel exists as a hydrocarbon-containing material constructed naturally in the earth's crust from the remains of dead plants and animals that exist extracted and burned as a fuel. The primary fossil fuels exist as coal, crude oil, and natural gas.

When fossil fuels exist burned, they release large quantities of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, pushing global warming.

Global warming exists usually directed to human-induced warming of the Earth system, whereas climate change can be direct to natural or anthropogenic change. The two phrases are often used interchangeably.

Answer:

D

Explanation:

Answer:

Synthesis, DNA helicase, topoisomerase, leading strand, lagging strand, DNA polymerase, nucleotides, primase, lagging strand, nucleotide, DNA ligase

Explanation:

During the process of DNA replication, the whole molecule gets copied in the synthesis or S phase of the cell cycle. The DNA strands are separated by the enzyme helicase while topoisomerase keeps it from overwinding. The 2 strands are copied differently. The leading strand is made continuously, while the lagging strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is DNA polymerase. This enzyme can only add nucleotides to an existing strand, so short sequences of nucleotides (primer) made by the enzyme primase are needed for the process of elongation. In the lagging strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while DNA ligase joins the fragments.

Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).

Explanation:

To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.

The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.

Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).

When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.

Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.

Answer:

variable expressivity; incomplete penetrance

Explanation:

In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:

a. The adrenal cortex is an extension of the parasympathetic nervous system.

c. The adrenal glands are strictly nerve tissue.

d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.

e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.

Explanation:

The  levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord.  Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs.  This alert serves as a warning signal and defense system.  The purpose is to maintain homeostasis.

Answer:

The approximate size of the field mice population is 2500 individuals.

Explanation:

There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the "Mark-Recapture technique".

The Mark-Recapture technique assumes that the population is closed,  during the sampling season there is no mortality nor natality, marks in the individual last the whole sampling season, and these do not affect the marked individual or their behavior. These marked individuals are randomly distributed in the population, and all the individuals have the same probability of being sampled.

The method consists of capturing a sample of individuals belonging to the population under study, in this case, the field mice population. After capturing the individuals, the researcher marks them and release them again. The third step is to sample again, capture a new amount of individuals, and count how many of them are marked. These marked individuals belong to the first sample. We can calculate the population size by using the Lincoln Index or any other index.

The Lincolns Index states that to obtain the population size, the research must follow the following procedure:

1) Take an initial sample with n1 number of individuals

2) Mark all the sampled individuals and release them

3) Take a second sample with n2 number of individuals

4) Count the number of marked individuals m

To estimate the total number of individuals in this population, N, the following equation must be considered:

N = (n1 x n2)/m

In the exposed example, this is:

• n1= 500 individuals in the first sample

• n2= 200 individuals in the second sample

• m= 40 individuals in the second sample that were previously marked  

             as they were part of the first sample    

N = (n1 x n2)/m = (500 x 200) / 40 = 2500 individuals

The approximate size of the field mice population is 2500 individuals.  

Answer:

159.01 mmHg

Explanation:

position of Heart = 2m  below the top of the head  given that the neck is fully extended

Determine the minimum diastolic pressure

Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m

                                               = 21200 kg/m^2

convert the value to Pa

21200 kg/m^2 = 21200 Pa

( 1 pa = 0.00750062 mmHg )

Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg

The minimum diastolic pressure that a giraffe must have is 150 mmHg

Diastolic Blood pressure is the pressure on the walls of your arteries between heartbeats, that is when the heart is resting.

P = hpg

where;

P = pressure

h = height difference

p = density

g = acceleration due to gravity

Density of blood = 1000 kg/m^3

h =2.0 m

g = 10 m/s^2

Pressure = 1000 × 2.0 × 10

Pressure = 20000 Pascal or 20 kpa

1 kpa = 7.50 mmHg

20 kpa = 20 × 7.50

Pressure = 150 mmHg

Therefore, the minimum diastolic pressure that a giraffe must have is 150 mmHg
