Answers

Plain bagel is the answer

The given blank can be filled with Plain.

The bagel is a round bread, which is made up of refined flour. The refined flour is less nutritious than the whole grain flour. The whole grain flour is used to make the whole grain bagel. Hence, the plain bagel is less nutritious than the whole grain bagel. The doughnut is made of plain bread, which is deep fried with sugar and cheese, which makes it less healthier than the plain bagel. Hence, the plain bagel is more nutritious than doughnut.

What role does differential reproduction play in natural selection?

A) Some organisms have different reproductive success due to nongenetic traits.
B) Some organisms have traits that help them reach reproductive age.
C) Different methods of reproduction result in some organisms being genetically altered.
D) Reproduction varies among organisms due to pathogenic factors.

The answer is not A

Answers

The answer would most likely have to be (D). Because its the only reasonable out of the selection.

B) Some organisms have traits that help them reach reproductive age. Differential reproduction is essential in natural selection because it favors the survival and proliferation of organisms with advantageous traits, thus ensuring those traits are passed down to future generations.

The role of differential reproduction in natural selection relates to the success of organisms in leaving behind reproductively viable offspring. Variations in traits can influence an individual's ability to survive and reproduce, thereby contributing to the genetic makeup of future generations. Those with traits that provide a better chance of survival and reaching reproductive age (Answer B) are more likely to pass on their genes. Differential reproduction ensures that favorable traits become more common in the population over time.

Reproductive success is crucial in natural selection because it is not merely about survival but also about producing fertile offspring that will continue the species. The combination of an organism's phenotype, its genotype, and the environment determines its reproductive success. Traits that enhance an organism's ability to survive and produce more offspring with similar advantageous traits are naturally selected over generations.

A water-soluble hormone approaches its target cell. Which will happen first? (2 points) The hormone's signal will be transduced through the cytoplasm of the target cell The hormone's signal will interact with the target cell's DNA The target cell will make proteins that alter the cell's function The hormone's signal will enter the nucleus

Answers

The hormone's signal is transduced through the cytoplasm of the target cell.

"Water-soluble hormones include glycoproteins, catecholamine's, and peptide hormones composed of polypeptides, e.g. thyroid-stimulating hormone, follicle-stimulating hormone, luteinizing hormone and insulin. These molecules are not lipid-soluble and therefore cannot diffuse through cell membranes.

A water-soluble hormone will first interact with a receptor on the surface of the target cell, initiating signal transduction through a second messenger without directly entering the nucleus or interacting with DNA.

When a water-soluble hormone approaches its target cell, the first event that will happen is that the hormone's signal will interact with a receptor located on the surface of the target cell. This hormone-receptor interaction triggers a signaling cascade that's known as signal transduction. During signal transduction, a second messenger within the cytoplasm - typically a molecule like cyclic AMP (cAMP) - will relay the signal from the cell membrane to various intracellular targets, eventually leading to the cellular response.

At this initial point, the hormone's signal does not enter the nucleus nor interact with the cell's DNA directly; instead, it indirectly exerts its effects through these intermediaries. Importantly, because the hormone is water-soluble, it cannot cross the hydrophobic plasma membrane on its own.

What type of graph curb symbolizes exponential growth?

Answers

An exponential growth graph looks pretty much like the right side of a parabola. The graph equation is f(x)= C ·a^x, so you can also plug in x values to find the y value. It's not a linear line, but it curves upwards starting from (0,0).

Final answer:

Exponential growth is represented by a J-curve, illustrating a sharp increase over time, unlike logistic growth which is shown as an S-shaped curve, indicating a stabilization of growth rate due to limiting factors.

Explanation:

The type of graph that symbolizes exponential growth is known as the J-curve. This pattern of growth is characterized by the way the curve steeply rises, representing a rapid increase over time. In the context of population growth, exponential growth occurs under ideal conditions with unlimited resources, where the population size increases at a constantly accelerating rate. It's important to differentiate this from logistic growth, which is represented by an S-shaped curve. Logistic growth starts similarly to exponential, but it levels off as resources become limited, illustrating a more realistic model of population growth where growth is exponential at first due to ample resources, then slows, and finally stabilizes at the carrying capacity of the environment.

In summary, exponential growth is depicted by a J-curve graph which shows a sharp, upward trend, indicating that the quantity being measured is increasing at a rapidly accelerating rate.

An athlete engages in some minor misbehavior. how should the coach respond to the athlete's misbehavior

Answers

The coach must avoid public confrontation as possible. The coach can remove the athlete from the practice or competition and misbehavior must be addressed privately. Athlete can have time to reflect on what they did. This will allow realization on their mistake on the situation that happened. Through this, they will not loss their confidence and self esteem which is needed as this can affect his performance during game and competition. 

Final answer:

A coach should address an athlete's minor misbehavior with corrective yet supportive guidance, making the rules for behavior clear, and using the incident as a teaching moment.

Explanation:

When an athlete engages in some minor misbehavior, it's important for a coach to address the situation with a response that is corrective yet supportive. Ignoring misbehaviors can sometimes lead to their extinction, especially if they're infrequent and don't significantly disrupt others.

However, behaviors that persist or affect the team should be managed more proactively. In such cases, a coach might use an athletic coach style of interaction, where the rules for behavior are consistent, objective, and presented clearly. The goal should be to provide guidance so the athlete can learn from the situation.

It is essential to discuss the misbehavior with the athlete, making clear why the behavior was inappropriate and what the expected behavior should be.

For instance, if the athlete copied the adult's behavior and faced consequences, acknowledging that as an adult, the coach also makes mistakes and emphasizing the learning opportunity can be a constructive approach.

By doing this, the coach models accountability and how to repair relationships, fostering a positive and respectful team environment.

AB because its two alleles are combined and dominant

When there are more than two alleles for a trait, these alleles are independently assorted to the next generation and express their characteristics in the next generation's offspring and are called as multiple allelism.

What is the significance of the trait expression?

The expression of the trait is determined by the nature of the trait, such as when some traits have only two alleles and one is completely dominant over the other, whereas in other traits, the alleles combine to express the effect. But some traits have more than two alleles, and they combine to express the trait, such as the skin color and the hair color of a human.

Rna contains the nitrogenous base ________ instead of ________, which is found only in dna. a deoxyribose sugar... a ribose sugar uracil... thymine uracil... guanine thymine... uracil

Answers

Both RNA and DNA are nucleic acids, and both are composed of nucleotides. The nucleotides are namely: Adenine, guanine, cytosine, thymine, and uracil. Adenine is always paired with thymine or uracil; guanine is always paired with cytosine. RNA contains the nitrogenous base uracil rather than thymine. DNA contains the nitrogenous base thymine rather than uracil.
Final answer:

RNA uses uracil in place of thymine, found in DNA, and has a ribose sugar instead of deoxyribose.

Explanation:

RNA contains the nitrogenous base uracil instead of thymine, which is found only in DNA. This means that during protein synthesis, adenine will always pair up with uracil in RNA, mirroring the pairing of adenine and thymine in DNA. Additionally, RNA includes the pentose sugar ribose, whereas DNA contains the pentose sugar deoxyribose, which has one less oxygen atom compared to ribose. The structural difference between uracil and thymine is that uracil is an unmethylated form of thymine, which is crucial for RNA's function in protein synthesis.

During transcription, in which direction is (1) rna synthesized and in which direction is (2) the dna template "read"?

Answers

(1) 5'→3';

(2) 3'→5'

 

During transcription, after the RNA polymerase has bound the promoter it begins to elongate the RNA primer in the 5’ to 3’ direction. However, the polymerase reads the DNA template in 3’ to 5’  direction. This is due to the fact that the created strand must be antiparallel to the template strand.






Final answer:

In transcription, RNA is synthesized in the 5' to 3' direction, while the DNA template is 'read' in the 3' to 5' direction by RNA polymerase.

Explanation:

During transcription, which is the process of synthesis of RNA from a DNA template, (1) RNA is synthesized in the 5' to 3' direction. This means that the RNA polymerase, which is the enzyme that creates the RNA strand, adds new nucleotides to the 3' end of the growing chain of RNA. On the other hand, (2) the DNA template is 'read' in the 3' to 5' direction by the RNA polymerase, which means that it starts at the 3' end of the DNA and moves towards the 5' end. This directionality is critical for the accurate processing of genetic information from DNA to RNA.

Answers

1. it acts as a framework inside the endoplasmic reticulum and keeps it from collapsing . It helps keep the organelles in place and directs their movement as needed . it keeps the DNA safely enclosed in the nucleus and holds the nucleus together . It provides anchoring places for the cell cytoplasm and help it move molecules.

2. D) The cell's energy level will diminish as the enzyme decreases

3. Whales have cells that produce energy differently than humans.

1. The right answer is It helps keep the organelles in place and directs their movement as needed.

The cytoskeleton provides a certain rigidity to the cell and serves for the fixation of organelles (equivalents for the organ cell for an organism).

The cytoskeleton is constantly reorganized and thus governs the internal movements (displacement of chromosomes for example) and the deformations of its membrane (production of protuberances, invaginations, sites of adhesions ...).


2. The right answer is The cell's energy level will diminish as the enzyme decreases.

Cellular respiration is the set of biochemical reactions leading to the formation of ATP,  energy source of the cell.

This mechanism consumes oxygen and creates carbon dioxide as waste. That's why we talk about cellular respiration.

It is the three-step set, glycolysis, the Krebs cycle and the electron transport chain related to oxidative phosphorylation, which lead to the formation of ATP. If these reactions are not assured by lack of enzymes then there will be no production of ATP (energy production).


3. The right answer is Whales are able to conserve oxygen better than humans.

As the duration of the dive of some whale species can reach more than one hour, they use other means to breathe. In vertebrates, myoglobin, a protein, transports and stores oxygen in muscle tissue. It works like hemoglobin that carries oxygen in red blood cells. It is also myoglobin concentration very strong that makes their flesh bright red color, almost black. Thus, whales use the oxygen stored in the muscles to dive for long periods.
