Answer:
The frequency of the non-taster phenotype among people of European descent is 49% or 0.49
Explanation:
Let us assume that the allele for tasting PTC is T, while that for not tasting PTC is t.
According to the Hardy-Weinberg equation : p² + 2pq + q² = 1
Also p + q = 1
Where p² is the frequency of individuals with the TT genotype for tasting PTC,; wow is the frequency of individuals with the heterozygous allele for tasting PTC, while q² is the frequency of the individuals with tt genotype expressed as the non-taster phenotype since the allele for tasting is dominant over that of the non-taster.
From the information provided 51% of people of European descent are tasters. Also, tasting PTC is dominant over non-tasting. This implies that individuals with TT genotype and Tt genotype will be phenotypically expressed as tasters.
Therefore p² + 2pq = 51% or 0.51
q² = 1 - p² + 2pq
q² = 1 - 0.51
q² = 0.49 or 49%
The frequency of the non-taster phenotype among people of European descent is 49% or 0.49

ANSWER:
Explanation:
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.

Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the low pressure system to the high pressure system, causing wind. The wind will carry moisture since it is coming from the ocean. Choose the statement which corrects the error(s) in Jennifer's prediction. (2 points)The wind from the ocean will not carry moisture.
The wind will travel from the high pressure system to the low pressure system.
Since the low pressure system is not over land, wind will not be created.
Wind is only created when two high pressure systems meet.
Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.

how does the ear function as a sense of "sight" for the blind?
Answer:
Neural scanning shows that even when only abstract sounds are used, the brain engages the visual cortex to build up an audio image. By learning the audio language, users can make their way around obstacles or identify and grasp nearby items.
The ear is not commonly thought of as a sense of "sight" for the blind, but some assistive technologies do use auditory cues to help people with vision impairments navigate and understand their environment.
What is echolocation?Echolocation is the ability of certain animals, such as bats, dolphins, and certain species of birds, to locate objects and navigate through their environment by producing sounds and listening to the echoes that are reflected back. These animals emit high-pitched sounds, such as clicks or whistles, and then use the echoes of these sounds to determine the distance, direction, and shape of objects around them.
The ability to echolocate is made possible by specialized structures in the animals' ears and brains that are able to detect, process, and analyze the echoes. In bats, for example, the larynx is modified to produce a variety of calls, while the ears are highly sensitive and specialized to pick up the echoes of these calls. Similarly, dolphins have a complex system of air spaces in their head, which they use to emit and detect sounds, as well as specialized neurons in their brain that can process the information gathered by echolocation.
Echolocation is an incredibly sophisticated and efficient system, allowing animals to navigate in complete darkness and through complex environments, and to locate and track prey even in the open ocean or in the dark.

In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?
Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.
PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.
The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.

1If you have 52.4 grams of hydrogen and 52.4 grams of helium, which one has a greater mass ? Why ?
Answer:
Hydrogen.
Explanation:
Hydrogen has greater mass and it's bigger than helium because as we move from left to right on the periodic table, atomic size decreases. Hydrogen atom is normally signified than H2 which is bigger than an atom of helium.
Also hydrogen has an atomic radius of 53pm while Helium has an atomic radius of 31 pm. Therefore the mass of helium is smaller than that of hydrogen.
