A. The difference between the two types of hydrogen bonds is that the bond between adenine and thymine is a double hydrogen bond and the one between cytosine and guanine is a triple hydrogen bond.
B. The double bond can only occure between adenine and thymine because they are a perfect match, it is its specific base partner. The same happens with guanine and cytosine, only them can form the triple bond.
This is called complementary base pairing

Answer: a change in body temperature
Explanation:
i just took the quiz and the other one was wrong
A change in body temperature is most likely to trigger a negative feedback mechanism in an organism.
Why negative feedback mechanisms are designed?Negative feedback mechanisms are designed to maintain homeostasis or a stable internal environment within an organism. Changes in body temperature can disrupt the balance of an organism's internal environment, and therefore, a negative feedback mechanism is triggered to bring the body temperature back to its normal range.
For example, if the body's temperature increases, a negative feedback mechanism would cause the body to sweat to reduce the temperature, while if the body's temperature decreases, the negative feedback mechanism would cause the body to shiver to generate heat.
On the other hand, a change in body temperature is an example of a disturbance that can trigger a negative feedback mechanism. When the body temperature increases, such as during exercise or exposure to hot environments, the hypothalamus in the brain detects the change and triggers responses to lower the body temperature.
Overall, a negative feedback mechanism is most likely to be triggered by a change in the internal or external environment that disturbs the equilibrium or stability of an organism.

The correct answer is -
a. 7
b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc
c. p7 is abundant
Explanation:
According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance
let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :
p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7
p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6
p5p5, p5p4, p5p3, p5p2, p5p1 - 5
p4p4, p4p3, p4p2, p4p1 - 4
p3p3, p3p2, p3p1 - 3

how does research in Social Psychology help to understand why sometimes our actions (behavior) do not match our attitudes (feelings often influenced by our Beliefs
Answers
Answer:
According to psychologist Gordon Allport, social psychology uses scientific methods "to understand and explain how the thoughts, feelings, and behavior of individuals are influenced by the actual, imagined, or implied presence of other human beings." What social psychology does is that it teaches us how people's social behavior is, and how we can match certain aspects of our emotions to uncalled attitudes. For example, someone may lash out at someone they truly love when they don't mean it, solely because they are upset. Social psychology can teach us how our feelings are coordinated with our beliefs and how we can react to them appropriately.

about _____ molecules in a glass of water are dissociated.
Answers
About 1 in 500,000,000 (one in half a billion) molecules in a glass of water are dissociated.
What is a molecule?
The science of molecules is called molecular chemistry or molecular physics, depending on whether it focuses on chemistry or physics. Molecular chemistry deals with the laws that govern the interactions between molecules that result in the formation and breaking of chemical bonds, while molecular physics deals with the laws that govern their structure and properties. A molecule can be homonuclear; H. consist of atoms of a chemical element, for example two atoms in a molecule of oxygen (O2); or it can be heteronuclear, a chemical compound made up of more than one element, such as water (two hydrogen atoms and one oxygen atom; H2O).
In the kinetic theory of gases, the term molecule is often used to refer to any gaseous particle, regardless of its composition. This reduces the need for a molecule to contain two or more atoms since noble gases are single atoms.

A series of experiments shows that oil content in a diploid grain is influenced by five genes (a through e) with additive alleles. The highest producing strain is 20% oil content; the lowest has close to 0%. A plant of unknown genotype has an oil content of 12%. What is a possible genotype for this plant
Answers
Answer:
All the possible genotypes of the plants that have an oil content of 12% include six dominant alleles. Following we are mentioning some of them
AABbCcDdEe, AaBBCcDdEe, AaBbCCDdEe, AaBbCcDDEe, AaBbCcDdEE
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
The possible genotypes involving a combination of six dominant alleles required for the grain to have an oil content of 12% are:
AABbCcDdEe, AaBBCcDdEe, AaBbCCDdEe, AaBbCcDDEe, AaBbCcDdEE
Additive alleles are alleles which result from polygenic traits.
Polygenic traits are traits which are encoded by several genes resulting in more than two alleles contributing to the phenotype.
The phenotype of additive alleles is continuous due to the many different combinations of the alleles of the genes.
From the data provided:
oil content in a diploid grain is influenced by five genes: a, b, c, d, e The highest producing strain is 20% oil content The lowest has close to 0%Since the grain is diploid, grains that are:
h0m0zygous recessive for the five genes, aabbccddee, will have 0% oil content.h0m0zygous dominant for the five genes, AABBCCDDEE, will have 20% oil content.Each dominant gene will contribute 20% / 5 = 4% of oil content.
Since the grains are diploid, each dominant allele will equally contribute 4% / 2 = 2% to the oil content.
Thus:
0 dominant allele → 0% oil content 1 dominant allele → 2% oil content 2 dominant alleles → 4% oil content 3 dominant alleles → 6% oil content 4 dominant alleles → 8% oil content 5 dominant alleles → 10% oil content 6 dominant alleles → 12% oil contentTherefore, a combination of six dominant alleles are required for the grain to have an oil content of 12%.
All the possible genotype involving a combination of six dominant alleles required for the grain to have an oil content of 12% are given below:
AABbCcDdEe, AaBBCcDdEe, AaBbCCDdEe, AaBbCcDDEe, AaBbCcDdEE.

how is active transport different from facilitated diffusion
Answers
Active transport and facilitated diffusion are two different mechanisms of moving substances across a cell membrane, with key differences in energy requirement, direction of movement, and specificity.
What is an active transport ?
Active transport is the movement of molecules or ions across a membrane against their concentration gradient, which requires energy in the form of ATP (adenosine triphosphate). Active transport can move substances from an area of low concentration to an area of high concentration, and it is often used by cells to maintain concentration gradients and perform functions like nutrient uptake and waste removal.
Facilitated diffusion, on the other hand, is the passive movement of molecules or ions across a membrane with the help of transport proteins. Facilitated diffusion moves molecules or ions from an area of high concentration to an area of low concentration, following the concentration gradient, and does not require energy input from the cell. Facilitated diffusion is often used to transport large or charged molecules that cannot diffuse across the membrane on their own.
Another key difference between active transport and facilitated diffusion is specificity. Active transport requires specific transport proteins, called pumps, that are designed to move specific molecules or ions. In contrast, facilitated diffusion can use a variety of transport proteins that are specific to certain molecules or ions, but can often transport a range of similar molecules.
In summary, the main differences between active transport and facilitated diffusion are that active transport requires energy input and can move substances against their concentration gradient, while facilitated diffusion is passive and moves substances along their concentration gradient. Additionally, active transport requires specific transport proteins and can be highly selective, while facilitated diffusion is less selective and can use a variety of transport proteins.

In which step of translation does the tRNA become charged?
A.

B.

C.

Answers
During translation, tRNA molecules are charged or activated with a specific amino acid that corresponds to their anticodon sequence. This activation process is catalyzed by aminoacyl-tRNA synthetases, enzymes that recognize specific tRNA molecules and attach the appropriate amino acid to their 3' end. The charged tRNA is then able to participate in the elongation step of translation, where it delivers its amino acid to the growing polypeptide chain. Therefore, the step of translation in which the tRNA becomes charged is called activation.

A different set of genes is transcribed in cells from patients in Group I compared to cells from patients in Group II For some genes, there is variation in the amount of mRNA present, even among patients in the same group.
If you were given microarray data from the cells of a new patient belonging to either Group I or Group II, you would probably be able to tell which group the patient belongs to.
All humans carry the same set of genes (although individuals' alleles can vary). However, different individuals and different cells may have different gene expression patterns. DNA microarrays reveal differences in these gene expression patterns by measuring mRNA levels in different cell samples.
In this study, you can see that there are distinct differences in gene expression between the cells of patients in Group I and Group II. The differences are clear enough that if you were given microarray data for a new patient, you would probably be able to predict whether the patient belongs in Group I or Group II. Note, however, that gene expression patterns are not identical within a single group -- there is variation in gene expression even among patients within a group.

Answers
The probability that an offspring will be short when two heterozygous pea plants are crossed is: B. 0.25
How to Determine the Probability of Offspring produced in a cross?When two heterozygous pea plants (Tt) are crossed, the probability of an offspring being short (tt) can be calculated using Punnett square analysis.
In this case, 25% of the offspring will inherit the recessive allele from both parents, resulting in a short plant phenotype.
The Punnett square is given below:
| T | t |
T | TT | Tt |
t | Tt | tt |
In the Punnett square, the combinations in the bottom row (Tt and tt) represent the possible genotypes of the offspring. As we can see, there is a 25% chance (1 out of 4) for an offspring to have the tt genotype, which corresponds to a short plant phenotype.
Therefore, the probability of an offspring being short is 0.25 or 25% (option B).
