Explanation:
Cellular respiration is one of the key biological processes that are literally sustaining life. It occurs in every living cell in order to provide it the energy (in the form of ATP) to carry out the several processes required to function as a cell or as an organism as a whole.
As the chromosomes of a parent cell are duplicated and distributed to the two daughter cells during cell division, the structure of the chromosomes changes.Answer the three questions for each phase of the cell cycle by dragging the yes and no labels to the appropriate locations in the table.Note: Assume that by the end of the M phase, the parent cell has not yet divided to form two daughter cells.Are sister chromatid present in all or part of this phase?Is the DNA condensed in all or part of this phase?Does the cell contain twice as much DNA in this phase as it did in the G1 phase?

Sister chromatids present in all or part of phase? ANSWERS BELOWDNA condensed in all or part of phase? ANSWERS BELOWDNA content per cell doubled in all or part of phase? ANSWERS BELOW**image also provided below for further clarification - all rights reserved to Mastering Genetics**
Explanation:
Conditions:
G1: no, S: yes, G2: yes, Beginning of M: yes, End of M: noG1: no, S: no, G2: no, Beginning of M: yes, End of M: yesG1: no, S: yes, G2: yes, Beginning of M: yes, End of M: yesBecause the replicated DNA is created, and the cell has twice as much genetic material, cells in the G2 phase have twice as much DNA.
What are the important phases of cell cycles?A diploid cell's G1 phase marks the start of the cell cycle (DNA content = 2 N; N is the number of chromosomes).
The cell enters the G2 phase with twice as much DNA (4 N) as the starting cell after DNA replication is finished in the S phase.
DNA replication happens in the S phase, when DNA synthesis happens and the amount of DNA doubles. Once the G1 phase is over, each chromosome contains one chromatid.
Each chromosome will have two chromatids following the S phase, though. The two chromatids here are exact duplicates of one another.
Therefore, When a cell is in the G1 phase, it physically expands and produces more protein and organelles.

Carolus Linnaeus Group of answer choices developed theories of natural selection. was a proponent of evolutionary change. established a binomial system of classification for plants and animals. was a supporter of Charles Darwin. opposed all notions of fixity of species.
Answer:
1- was a proponent of evolutionary change.
2- established a binomial system of classification for plants and animals
Explanation:
Carolus Linnaeus was a Sweden naturalist that is considered to be the creator of the modern taxonomy. He created a dichotomic system to classify species, in which species are fixed entities without phenotypic modifications across time, this concept being contrary to Darwin's ideas. Linnaeus published his nomenclature botanical system in the book "Species Plantarum", which is nowadays a reference book for plant nomenclature.

Which capillary would be least likely to allow substances to enter or exit the blood due to tight junctions that join the endothelial cells
Answer:
Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.
These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.
The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective
Explanation:
The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.
This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.
An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that
the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
The alleles for tall height and short height are codominant.
The allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.
The student could use their graph as evidence to support the argument that "The alleles for tall stature and short stature are codominant."
What is a Codominant gene?Codominant: Autosomal codominant inheritance is the condition in which the heterozygote has the characteristics determined by both alleles (dominant and recessive).
What is allele?Allele genes are those that occupy the same locus on homlogous chromosomes and are involved in determining the same character.
With this information, we can conclude that the genes alleles of the students in this class are codominant.

A microbiologist would like to use a noncompetent genus of streptococcal bacteria, Enterococcus faecalis, as a cloning host to express genes from Streptococcus pneumoniae, which is naturally competent. Is this possible? Group of answer choices
Answer:
Yes, with the assistance of electroporation the bacteria Enterococcus can be made competent, and afterward, the Streptococcus bacterial genes can be presented within the Enterococcus with the help of a cloning vector.
The electropermeabilization or electroporation refers to a microbiology technique in which the permeability of the cell membrane is enhanced with the application of the electric field. This permits drugs, chemicals, or DNA to get presented within the cell.
The procedure of electroporation is generally used in the field of microbiology to transform yeast, bacteria, or protoplasts of plants by presenting novel coding DNA.

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4, b = 5, c = –2 a = 4, b = –5, c = –2
Hey there! :)
Answer:
The 3rd choice. a = -4, b = 5, c = -2.
Explanation:
Rearrange the quadratic equation given into the form 0 = ax² + bx + c:
0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2
The corresponding coefficients for the a, b and c values are:
a = -4
b = 5
c = -2.
The given quadratic equation must be first rearranged in the form ax2- bx-c. From this, we can find the values of a= -4, b= 5, and c= -2
How can a quadratic equation be defined?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is ax² + bx + c = 0.
Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, while working with the area, if both dimensions are represented in terms of the same variable, you use a quadratic equation.
Throwing a ball, shooting a cannon, diving from a platform, and hitting a golf ball are all examples of situations that can be modeled by quadratic functions.

Jessica weighs 125 pounds. She rode a bike at 17mph for 25 minutes. What is the calorie cost of this activity?
a. 185 calories
b. 178 calories
c. 180 calories
d. 190 calories
e. 188 calories
Answer:
b. 178 calories
ok so 17mph is 0.57 weight/min
so what were going to do is multiply 125 times 0.57 which is 7.125
then multiple that answer by 25 mintues: 7.125 x 25 = 178.12...etc
now if we round this up it stays as 178!
If the scientist had collected 20 dung samples, would you expect more bands, fewer bands, or the same number of bands on the gel?
Answer:
The expectations of the bands will be more on the gels.
Explanation:
One sample provides several sizes and thickness bands in the gel electrophoresis according to the size of fragments that run in it. An individual would expect more bands due to the increase in the number of samples which is 20 samples now.
An increase in the number of samples produces more bands. So one can easily expect more bands from the 20 samples. Scientists would get more bands on the gels.
Thus, the expectations of the bands will be more on the gels.
If the scientist collects 20 dung samples ; we should expect more band on the gel
Given that each dung sample has varying sizes and varying thickness of bands in the gel electrophoresis which depends on the size of fragments contained in it. Therefore when a number of dung samples ( 20 ) are collected it is only logical that the number of bands on the gel will increase ( i.e. you should expect more band on the gel ).
Hence we can conclude that If the scientist collects 20 dung samples we should expect more band on the gel .

(sodium potassum adenosine triphosphatase) is found in the plasma membrane and catalyzes the exchange of sodium and potassium ions across the membrane. Classify the statements about the transport system as either true or false.
Answer:
The statements are:
Pumps K+ out of the cell False
Pumps K+ions into the cell True
Exchanges 3 Na+ ions for 2 K ions+ True
Exchanges 3 K+ ions for 2 Na+ ions False
Creates a membrane potential that is negative on the inside True
The transport protein becomes adenylated by ATP during the transport cycle True
Pumps Na+ ions out of the cell True
Pumps Na+ ions into the cell False
Explanation:
Sodium Potassium Adenosine Triphosphatase is in the membrane of cells. Its function is to create a difference of charges between the inside and the outside of the cell. The enzyme pumps 3 Na+ ions outside the cell for every 2 K+ ions that pumps inside the cell producing a resting potential. As this process is against their concentration gradient, the protein needs the energy to do it. This energy comes from the ATP that attaches to the transport protein.
