3. Sketch a before and an after diagram of an animal cell placed in a hypotonic
solution
Answers
If an animal cell is placed in a hypotonic solution significantly for some period of time, it will eventually swell and finally burst. This process is known as cytolysis.
What is a Hypotonic solution?A hypotonic solution may be defined as a type of solution that typically contains a lower amount of solute as compared to the solute concentration in other solutions, across a semipermeable membrane.
According to the context of this question, when a cell is placed into a hypotonic solution, it will absorb the water content from outside and due to water consumption, it will swell and expand until it eventually bursts. This process of swelling and bursting of cells due to water consumption or absorption is known as cytolysis.
Therefore, if an animal cell is placed in a hypotonic solution significantly for some period of time, it will eventually swell and finally burst.

What new details are you able to see on the slide when the magnification is increased to 10x that you could not see at 4x? What about 40x?
Answers
As the magnification increases, more specific information, such as the nucleus of cells on the slide, is seen.
What is magnification?
The majority of compound microscopes include objective lenses, which are replaceable lenses. The most popular magnification powers for objective lenses are 4x, 10x, 40x, and 100x, commonly referred to as scanning, low power, high power, and (usually) oil immersion objectives.
More minute characteristics of the cells and the form of the stained nuclei may be seen at a magnification of 40 times. You can see a smaller area of the specimen because of the reduced field of view at higher magnifications. Furthermore, keep in mind that although appearing to be incredibly thin, the item on the slide actually has a thickness.

Which base is found only in DNA?
O adenine
O guanine
O cytosine
othymine
Answers
explanation
DNA is a complex chemical compound which carries genetic information of a living being. It is a double helix structure. The full form for this is deodorize nucleic acid.
Thymine is the base that is found only in DNA. Adenine, guanine, and cytosine are also present in both DNA and RNA, but thymine is exclusive to DNA. In RNA, uracil replaces thymine.
What are nucleotide bases?Nucleotide bases are the building blocks of DNA and RNA, the genetic material in all living organisms. There are four nucleotide bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine. These bases pair with each other to form the "rungs" of the DNA ladder, with A always pairing with T (or U in RNA) and C always pairing with G.
The sequence of nucleotide bases in DNA determines the genetic information carried by an organism. DNA replication, the process of copying DNA before cell division, relies on the complementary base pairing of nucleotide bases to ensure that each new strand of DNA has the same sequence as the original.
Mutations, or changes, in the sequence of nucleotide bases can occur naturally or as a result of external factors such as radiation or chemical exposure. These mutations can lead to genetic variations and may have consequences for the organism.

What does the forward arrow in a chemical equation mean? (1 point)
O The reaction is reversible.
O The reaction proceeds slowly.
O The reaction proceeds quickly.
O The reaction yields something.
Answers
Answer:
D.) The reaction yields something.
Explanation:
A.) is incorrect. A forward arrow means a reaction only occurs in the forward direction (reactants to products). If the reaction were reversible, there would be double arrows, one pointed forward and another pointed backwards. This would symbolize that the reaction can take place in both directions.
B.) and C.) are incorrect. The direction of the arrow in a reaction gives no information regarding the rate of the reaction.
D.) is correct. In the case of chemical reactions, to yield something means to create something. A forward arrow indicates that reactants are undergoing a chemical reaction to form/yield new products.

apply chargaffs decide how many guanine bases and length of DNA will have if it has 26 cytosine bases. explain.
Answers
Answer:
According to Chargaff's rule, if a DNA molecule has 26 cytosine base molecules it will also have 26 guanine molecules.
Explanation:
DNA is formed by the bases adenine guanine, thymine and cytosine, distributed in its two strands whose proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff found that in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there should be the same amount of thymine as adenine and a similar amount of guanine for cytosine, according to the complementarity of the bases.
According to Chargaff, if a DNA molecule contains 26 cytosine bases —one pyrimidine— then it also contains 26 guanine molecules, one purine.
In the case that the molecule has a total of 100 nitrogenous bases, the amount of the other bases can also be known:

In the compound microscope, If you see bacteria move to the right,
this bacteria on the slide, really move to:
O a. Left
b. Downward
on
c. Upward
O d. Right
Clear my choice
Answers
Answer:
a
Explanation:
In a compound microscope, if a bacterium moves to the right, the bacterium on the slide, in reality, moved to the left.
This is because the optical system of the compound microscope is designed in such a way that the lenses change the orientation of the image of objects when viewed.
The system of two lenses - the objective and the eyepiece - produce inverted images of objects on slides. Hence, when an object on the slide under the compound microscope moves to the right, it is seen as moving to the left to the viewer and when it moves up, it is seen as moving down by the viewer.

Answers
0.25 recessive alleles are present in your overall population.
What are recessive alleles?In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest. When there is only one copy of an allele, it has no effect at all.
This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, 0.25 recessive alleles are present in your overall population.

which respiratory substrate has a respiratory quotient of 0.5
Answers
The RQ is the ratio of the patient's carbon dioxide production (VCO2) to his or her oxygen consumption (VO2). These values are obtained by indirect calorimetry at the patient's bedside. The RQ is helpful in guiding the planning of nutritional therapy. The physiologic range for RQ values is 0.7 to 1.2 and is influenced by the relative contribution from fat, protein, and carbohydrate. RQ values for fat, protein, and carbohydrate are 0.7, 0.8, and 1.0, respectively. Thus, an RQ of >1.0 might suggest excessive carbohydrate or calorie provision that can result in increased CO2 production and cause difficulty weaning from mechanical ventilation. A RQ of <0.7 might suggest underfeeding and use of ketones as a fuel source. The use of energy fuels by animals and by a flame may be compared by considering the stoichiometry of the chemical reactions. They may also be compared by noting the amount of energy produced with complete oxidation of the fuel in question. The following discussion begins with the stoichiometry of combustion of simple compounds — such as paraffin, methane, and methanol — and then continues onto the combustion of more complex materials — such as glucose and fat. The study of the stoichiometry of various reactions requires the counting of the number of molecules of CO2 produced per molecule of fuel combusted, the number of water molecules produced, and the number of oxygen atoms (or molecules) consumed.
The stoichiometry involved in the combustion of fuels can be used to calculate a very interesting ratio: the number of CO2 molecules discharged from the body per number of oxygen molecules consumed. This ratio (CO2/O2) is called the respiratory quotient (RQ). The biochemical events of CO2 production and O2 utilization are a direct result of the oxidation of various fuels such as fat and glucose. The amount of O2 used is also influenced by the rate of synthesis of new fat in the body. Respiratory gases can be measured and analyzed quite easily. These measurements can be used to calculate the amount of CO2 produced and O2 used by the body over any given period. Calculating the RQ for a subject is quite easy and can provide remarkable insight into the overall behavior of energy fuels in the body. The RQ can provide only limited information on metabolism, but it is a powerful measurement.
The RQ is different for different fuels. For example, the RQ for the complete combustion of glucose is 1.0, and that for the complete combustion of fat is 0.7. These values are determined in three ways:
1.
On paper, by balancing chemical formulas, with no knowledge of metabolic pathways.
2.
By consideration of the biochemical pathways of the body, providing that these pathways have been memorized or are available in some format.
3.
Experimentally, by use of a furnace. The furnace contains an atmosphere of pure oxygen. A mechanism for igniting the fuel or food in question, as well as devices for measuring the amount of CO2 produced and O2 consumed, is available.
Knowledge of the RQ for different energy fuels can be used to determine the predominant fuel used by a particular organ of the body, such as the muscle or brain. To determine the RQ for a particular organ, the blood entering and exiting that organ must be analyzed. Most of the oxygen entering and exiting the organ is bound to hemoglobin. Most of the CO2 entering and exiting the organ is in the form of bicarbonate.
