Eye color, hair color, and skin color are polygenic traits. Polygenic traits result from many genes.
What are polygenic traits?Polygenic traits are traits that are influenced by multiple genes. These genes may interact with each other and with environmental factors to determine the final expression of the trait. Examples of polygenic traits include height, eye color, skin color, hair color, and body weight. The phenotype of a polygenic trait is determined by the combined effect of multiple genes, each with a small effect, rather than a single gene with a large effect.
As a result, the phenotype is often continuous and can range from one extreme to another, rather than being limited to a few distinct categories. The study of polygenic traits provides important insights into the genetic basis of complex traits and the interactions between genes and the environment, and can also inform our understanding of the genetic basis of diseases and disorders.

How does photosynthesis benefit heterotrophs? * 6 points It adds carbon dioxide to the air. It creates food that they can eat. It eliminates harmful sugars. It creates clean water.
Answer:
The correct answer is ''It creates food that they can eat.''
Explanation:
The first link or first trophic level, of any food chain is always represented by the producers, (plants, which are photosynthetic organisms), autotrophic organisms, which are capable of transforming the light energy of the sun into a type of energy that can be used by the rest of the living beings. All heterotrophic organisms depend on these energy and matter conversions for their subsistence, that is, animals eat plants and take advantage of those organic compounds to create their own body structure, since heterotrophs, like humans, cannot carry out the photosynthesis, obtain energy by consuming autotrophs and their derivatives.
The process of photosynthesis is beneficial for heterotrophs as it creates food that they can eat. The correction option is option B.
Autotrophs produce their “food” by photosynthesis (using the sun’s energy), while heterotrophs do not have the ability to produce their own food.
Autotrophs must consume or absorb their food, whereas heterotrophs produce food through chemosynthesis (using the chemical energy in inorganic molecules.
Humans rely on photosynthesis to create the food they eat every day, as well as to generate heat, light, and electricity. Autotrophs are also producers in nearly all food chains, so photosynthesis is important for humans too.
Therefore the correct option is option B.

which statement best explains how organ systems in the human body function
A. They work at different times to conserve energy
B. They work together to benefit the entire organism
C. They work at different times, depending on their job
D. They work independently of each other, for efficiency
The statement that best explains how organ systems in the human body function is they work together to benefit the entire organism. The correct option is B.
What is the organ system?Organ systems are collections of organs that cooperate to perform certain tasks for the organism. The cardiovascular system, for instance, is made up of the heart and blood arteries.
The coordinated activity of an organ system's organs determines how well it functions. To process food, for instance, the digestive system's organs work together.
The coordinated operation of all organ systems, frequently coordinated by the endocrine and neurological systems, is necessary for the organism to survive.
Therefore, the correct option is B. They work together to benefit the entire organism.

Which statement best describes the driving force behind all the weather on Earth, from local weather systems to large-scale storms? A. The Sun heats the atmosphere unevenly, so temperatures and pressures are constantly equalizing. B. The ocean holds the heat of the Sun more efficiently and for longer periods than land. C. The Greenhouse Effect ensures that some of the Sun's heat is always trapped close to the Earth's surface. D. The Coriolis Effect curves the motion of wind due to the Earth's counter-clockwise rotation.
Answer:
A. The Sun heats the atmosphere unevenly, so temperatures and pressures are constantly equalizing.
Explanation:
Solar energy is the most important force that stands as responsible for the occurrence of all the atmospheric changes on the Earth. The solar energy is received and reflected back by the earth's surface. The amount of solar energy is responsible for the occurrence of the water cycle, formation of the clouds, presence of humidity in the atmosphere. The Earth's temperature is maintained when the reradiated solar energy is absorbed by other gases.
