For a specific cactus plant, cacti homologous for red flowers were crossbred with cacti homologous with white flowers. The next generation was 100% pink, then it is called as incomplete dominance as the offsprings are different from the parents.
What is incomplete dominance?Incomplete dominance is a type of inheritance where the offspring that is produced is neither like the paternal parent nor like the maternal parent but will show the different intermediate type of trait that is pink in this case. Here , the pink trait is the intermediate trait of the red and the white that is present in both of the parents, and this type of the offsprings shows different trait when they have the heterozygous states. When this two pink flowers cross then there are the production of the one red, one white and two pink flowers.
Hence, the next generation was 100% pink, then it is called as incomplete dominance as the offsprings are different from the parents.

Can you please help me with this?
Answer:
The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.

Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swaps genetic information with a different chromosome (this is NOT Crossing Over). O Inversion O Duplication O Deletion O Translocation
Answer:
The correct answer is ''Translocation.''
Explanation:
Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.

The Aquarius Personality: The Water Bearer (Jan 22 – Feb 21)
The personality of an Aquarius is characterized by the need for self-expression, creativity, and a sense of purpose. Aquarians have a natural curiosity about many things and are more than willing to use their far-reaching imaginations to feed that curiosity. Friends or colleagues of an Aquarius may find these unpredictable individuals to be warm and affectionate, though sometimes solitary, relentless in their pursuit of knowledge, and deeply inquisitive.
What Are the Best Career Paths for an Aquarius?
Although Aquarians are highly capable of many things, they are best suited for roles that require unconventional thinking. Aquarians embody many professional strengths, including critical thinking, social consciousness, and assertiveness.
However, the Aquarian personality has its drawbacks like other zodiacs. An Aquarius can lack focus, express apathy toward tasks that diverge from their interests, and insist on getting their way, even when that may not be beneficial for completing the task at hand. These qualities can cloud the Aquarian’s better judgment and stunt their professional growth.
However, positive Aquarian traits aid in professions in service, politics, and fine arts. These career paths allow the Aquarius to flourish in ways that are comfortable for them while encouraging them to amplify the best aspects of their personalities.
What Are Aquarians Like in the Workplace?
An Aquarius will feel at home in work environments that welcome the deep, abstract thought process that is natural to them, such as laboratories and museums. In these work environments, the Aquarius can jump at the chance of aiding a colleague or lightening the load of a manager; they naturally enjoy being helpful to others.
While their thoughtfulness and instinct to help can be great assets in the workplace, Aquarians also have some tendencies which create challenges in the workplace. Aquarians tend towards self-isolation. An Aquarius should remember that not everyone works this way, and that their colleagues will still be expecting communication from them. Disconnecting without notice can make an Aquarius a difficult coworker. Aquarians should inform their colleagues or managers about their desire for occasional solitary tasks during the workweek and explain how it improves their work, being both truthful and proactive in their attempt to overcome the challenge.
Along similar lines, another challenge that Aquarians are likely to face at work is having to adhere to a schedule instead of doing as they please when they please. Aquarians can become irritable when they cannot do what they want, and as we all know, work often includes doing things that are not aligned with things we like to do. Unfortunately, there is no magic fix for this, and Aquarians will have to learn how to fulfill work obligations that include fun and not-so-fun duties. Aquarians can overcome this workplace challenge by redefining what happiness looks like for them at work. The Aquarian may not find joy in fulfilling a task that they do not want to do, but may instead find happiness in getting the work hours they want (to schedule more of what they want to do in their personal time). If the Aquarius can learn to reciprocate what they want at work, they are likely to find greater enjoyment in their professional experiences.

ATP
Answer:
Rubisco.
Explanation:
Las reacciones del ciclo de Calvin añaden carbono (del dióxido de carbono en la atmósfera) a una molécula sencilla de cinco carbonos llamada RuBP. Estas reacciones usan la energía química de la NADPH y del ATP que se producen en las reacciones luminosas. El producto final del ciclo de Calvin es la glucosa.
Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings are expected to be heterozygous for both traits?
Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%
