The only people with Rh negative blood are people who have inherited two recessive alleles for this trait. But some people who are colorblind have inherited only one recessive allele for this trait. Explain why these traits are different in terms of how many recessive alleles are needed to produce the recessive phenotype. Hint: Think about the above problem and sex chromosomes versus autosomes.
Answers
The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.
What are the blood type and Color-blindness inheritance patterns?
⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.
The allele Rh+ dominates over the allele Rh-.
Genotyopes and Phenotypes are as follows,
Individuals Rh+Rh+ express the possitive phenotypeIndividuals Rh+Rh- express the possitive phenotype Individuals Rh-Rh- express the negative phenotype.To express Rh-, a person must inherit two recessive alleles from their parents.
⇒ Color-blindness is an X-linked condition coded by a recessive allele.
As most sex-linked genes, it is transmitted together with the X chromosome.
The phenotype depends on the number of recessive alleles and the sex of the person.
Genotyopes and Phenotypes are as follows,
X⁺X⁺ women have normal sight.X⁻X⁻ women are completely color-blinded X⁺X⁻ women are partially color-blinded. X⁺Y Men are not color-blinded X⁻Y Men are color blinded.In this case, only one recessive allele is enough to express the affection.
In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.

Let the retention factor of species A be 0.5, while the retention factor of species B be 0.3. If species A moves 1.0 cm how far does species B move
Answers
Answer:
The correct answer is - 1.2 cm.
Explanation:
The retention factor is represented by Rf.
Given:
Rf of species A is = 0.5
Rf of species B is = 0.6
Formula:
Rf = distance the compound moves/distance the solvent moves
Rf(A)/Rf(B) = \(\frac{distance moved by A/distance moved by solvent}{distance moved by B/distance moved by solvent}\)
Rf(A)/Rf(B) = distance moved by A/distance moved by B
0.5/0.6 = 1/distance moved by B
distance moved by B = 0.5/0.6
= 1.2 cm
The distance traveled by species B if species A moves 1.0 cm is 0.6 cm
The Retention factor \(\mathbf{R_f}\) is the ratio of the distance moved by the species by the distance moved by the solvent front.
From the information given:
\(\mathbf{R_f(A) = 0.5}\)\(\mathbf{R_f(B) = 0.3}\)For specie A;
\(\mathbf{0.5 = \dfrac{1.0 \ cm}{distance \ moved \ by \ solvent \ front}}\)
\(\mathbf{distance \ moved \ by \ solvent \ front= \dfrac{1.0 \ cm}{0.5}}\)
distance moved by solvent front = 2 cm
For specie B;
The distance traveled by the species B will be:
= 0.3 × 2.0 cm
= 0.6 cm

Explain the limitation binomial nominclature (15 marks)
Answers
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.
How can poor nutrition affect individual cell functions?
Answers
Answer:
Nutritional imbalance is a major challenge for living organisms to achieve systemic homeostasis and maintain normal physiology. Mammals have developed processes to control systemic nutrient utilization and storage. For example, excess nutrients are converted and stored in adipose tissue, liver, and muscle during times when nutrients are abundant. By contrast, stored nutrients are metabolized to provide energy and building blocks to maintain vital physiological processes when nutrient availability is low.
From these processes, adipose tissue volume changes in response to under- or overnutrition. This change in adipose tissue volume, in turn, influences the secretion of hormones and cytokines from adipose tissue (adipocytokines). Many of these adipocytokines have important immune signaling functions which can influence immune cell biology and alter the immune response.

My question:
As an analogy of a circuit with resistance, think of an obstacle race . Which parts of a circuit do the obstacles represent? which part of the circuit do the people respresent?
Answers
Answer:
An obstacle race can serve as an analogy for understanding the components of a circuit with resistance. In an obstacle race, participants navigate through various obstacles to reach the finish line. Similarly, in a circuit with resistance, electrical current encounters obstacles that impede its flow. By associating different elements of an obstacle race with corresponding parts of a circuit, we can gain insights into how resistance affects the flow of electric current.
Explanation:
Obstacles as Resistance: In an obstacle race, the obstacles represent the resistance in a circuit. Just as obstacles require participants to exert more effort to overcome them, resistance in a circuit hinders the flow of electrical current. The resistance can be caused by factors like the material of the wire or components like resistors, which impede the smooth flow of electrons.Participants as Electric Current: The people participating in the obstacle race represent the electric current in a circuit. Like the participants moving through the racecourse, electric current moves through the circuit, aiming to complete the circuit and reach the intended destination. The flow of current is driven by a voltage source, analogous to the motivation and energy of the participants in an obstacle race.Finish Line as the Destination: In an obstacle race, the finish line represents the destination or endpoint. Similarly, in a circuit, the destination is the point where the electric current aims to reach. This could be a device that utilizes the electrical energy, such as a light bulb or a motor, where the current is transformed into other forms of energy.By drawing parallels between an obstacle race and a circuit with resistance, we can visualize how resistance hampers the flow of electric current and understand the role of different components in a circuit. Just as participants navigate obstacles to reach the finish line, electric current overcomes resistance to reach its intended destination, where it can be utilized to perform useful work.

Which sense of tiger is strong and how this smell help the animal in finding the fodd
Answers
The sense of smell in tigers is highly developed and serves as a critical tool for survival. It helps them locate prey, establish territories, detect potential threats, and identify reproductive opportunities. The acute sense of smell in tigers enhances their hunting efficiency and contributes to their overall adaptation as top predators in their habitats
The sense of smell in tigers is particularly strong and plays a crucial role in their survival. Tigers have a highly developed olfactory system, equipped with specialized receptors in their nasal cavity that allow them to detect and discriminate various odors in their environment.
The sense of smell is essential for tigers when it comes to finding food. Tigers are carnivores and rely on hunting to sustain themselves. Their acute sense of smell helps them locate potential prey, even from a distance. Tigers can detect the scent of other animals, such as deer or wild boar, which enables them to track and stalk their prey effectively.
The olfactory system of tigers allows them to detect not only the presence of potential prey but also to gather information about the prey's location, health, and even reproductive status. They can identify the scent markings left by other tigers, which help them establish and defend their territories. Additionally, tigers can use their sense of smell to detect the presence of rival tigers or potential threats in their surroundings.
The ability to smell plays a vital role in a tiger's hunting strategy. Tigers often rely on ambushing their prey, and a keen sense of smell allows them to analyze the scent trails left by potential prey, determining their direction and estimating the distance to their target. This helps tigers plan their approach and execute precise and efficient hunting strategies, increasing their chances of a successful kill.
Moreover, a tiger's sense of smell is not only limited to locating prey but also plays a role in identifying potential mates. During the breeding season, female tigers release pheromones that indicate their receptiveness to mating. Male tigers can detect these scents and use them to locate and court females.
