Xenotransplantation is using nonhuman animal organs in transplantation. Many people are against this practice. What would be the best argument for why xenotransplantation should be accepted?
A. There are more people on transplantation lists than donor organs so xenotransplantation can save people’s lives
B. People on transplantation lists are not treated equally in that some are moved to the top of the list
C. There are no antigens on the surface of nonhuman animals so there would be no rejection
D. More organs can be extracted from nonhuman to accommodate more recipients
Answers
Answer:
A. There are more people on transplantation lists than donor organs so xenotransplantation can save people’s lives
Explanation:
Xenotransplantation, ie using non human animal organs in transplantation, has following most crucial favouring argument
Patients needing transplanted organs are much higher than people willing & able to donate them. So, there is extreme excess demand, needed to be satisfied for saving people's lives.Answer:
The answer is A

Exceeding threshold depolarization at the trigger zone______the likelihood of generation of an action potential.
Answers
Answer: Exceeding threshold depolarization at the trigger zone decreases the likelihood of generation of an action potential.
Explanation:
Exceeding threshold depolarization at the trigger zone decreases the likelihood of the generation of an action potential.
What is threshold depolarization?Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated. The amplitude of the action potential decreases with distance. The number of action potentials increases as the frequency of stimulation to the trigger zone increases.
Because the potassium channels within the cell membrane are delayed, any additional sodium entry activates an increasing number of voltage-gated sodium channels. Depolarization above the threshold causes an increase in Na conductance sufficient for inward sodium movement to instantly swamp outward potassium movement.
Therefore, Excessive depolarization at the trigger zone reduces the likelihood of an action potential being generated.

How can no color change in the broth and a conversion to a yellow color both be considered negative results?
Answers
Answer:
Explanation:
A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.
When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.

Answer:
A.
Explanation:
Kinetic energy turns tidal turbines to create electrical energy.
What is kinetic energy?Kinetic energy is a type of motion energy, where potential energy can be defined as energy stored to be utilized.
Kinetic energy is very common to be converted into different types of energy to produce electricity.In this case, kinetic energy is first converted to mechanical energy (i.e., by the motion of turbines).In conclusion, kinetic energy turns tidal turbines to create electrical energy.

Indicate which of the following observations can be made when observing growth on nutrient agar. Group of answer choices Gram reaction of growth Acid-fast morphology Amount of growth Opacity/clarity of colonies Color of colonies Presence or absence of endospores Shape and /or pattern of growth
Answers
Answer:
Amount of growth
Opacity/clarity of colonies
Color of colonies
Shape and /or pattern of growth
Explanation:
An agar plate is a Petri dish containing agar as a solid growth medium supplied with nutrients (i.e., an enriched medium), which enable to culture different microbes ranging from fungi to bacteria. Colony morphology is a widely used approach to describe the unique features of bacteria colonies growing on agar media. These colony features include, among others, shape (round, circular, punctiform, irregular), elevations/depressions (convex, concave, flat), textures (dry, moist, crusty, dull, shiny, mucoid, friable, rough), colors (cream, white, purple, gray, red, green, yellow, blue), etc.
The observation that could be made regarding the growth over nutrient agar would be:
C). Amount of growth
D). Opacity/clarity of colonies
E). Color of colonies
G). Shape and/or pattern of growth.
Observation
The growth of nutrient agar can be observed in above-mentioned ways. The area covered during the growth, the level of clarity amongst them, the color developed by them, and their size and formation as well.This assists in making worthy deductions about them.Thus, options C, D, E, and G are the correct answers.Learn more about "Morphology" here:

The inner and outer surfaces of a cell membrane carry a negative and positive charge, respectively. Because of these charges, a potential difference of about 70 mV exists across the membrane. The thickness of the membrane is 8 nm. A) If the membrane were empty (filled with air), what would be the magnitude of the electric field inside the membrane? (Assume that this field would be constant in magnitude). B) If the dielectric constant of the membrane is K = 3, what would the field be inside the membrane?3) Cells can carry ions across a membrane against the field ("uphill") using a variety of active transport mechanisms. One mechanism does so by using up some of the cell's stored energy (converting ATP to ADP, for those who remember their biochemistry). How much work does it take to carry one sodium ion (charge = +e) across the membrane against the field?
Answers
The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively. Because of these charges, a potential difference of about 0.070 V exists across the membrane. The thickness of the cell membrane is 8.0 x 10-9 m.
MEIOSIS. Questions

E) What will the cells in step 4 mature to become?
Answers
Answer:
A. DNA replication
B. Two haploid daughter cells
C. Four haploid daughter cells
D. No, they are not the same

Explanation:
A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.
B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.
C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.
D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.
E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.
