So how do we get chickens with white and black spots? Shouldn’t they be only white or black?
Answer:
Codominance
Explanation:
This is an example of codominance.
Basically with this type of genetics, both alleles for that trait, in this case feather color, are dominant. This means that both will appear in the phenotype, instead of a dominant phenotype overshadowing a recessive phenotype.
Here, the two dominant alleles are the one that governs white pigment and the one that governs black pigment. Since codominance is occurring, we see a speckled chicken instead of just an entirely white one or an entirely black one.

Is knowing about the physical and chemical changes of food important for a molecular gastronomy chef?
Yes, knowing about the physical and chemical changes of food important for a molecular gastronomy chef.
Explanation:
Molecular gastronomy involves cooking recipes with the knowledge of the basic science behind food, the various chemical and physical changes that happens to the various ingredients due to the cooking process.
Gastronomic chefs apply various scientific principles while preparing, cooking, serving, and storing food to make it more tasty and present a great dining experiences.
Using technology and science to create foams of whipped cream, mousse; spherification of liquids like fruit juices; applying appropriate temperature control etc are utilized by these chefs. The various change of state of matter is applied to understand the physical and chemical changes of food by the molecular gastronomy chefs.
Molecular gastronomy chefs greatly benefit from understanding the physical and chemical changes of food, as this knowledge allows them to create innovative dishes with precise control over flavors, textures, and visual effects.
Explanation:Understanding the physical and chemical changes of food is indeed crucial for a molecular gastronomy chef. Molecular gastronomy is an innovative culinary field where understanding food at a molecular level allows chefs to create new textures, flavors, and visual effects to enhance the dining experience. By comprehending the thermochemistry involved in cooking, chefs can manipulate the energy content and reaction rates to achieve desired culinary results. Whether using knowledge of the Maillard reaction to add complexity to flavors or employing emulsifiers for stable foams and sauces, chefs exploit chemistry in cooking to innovate and excite the palate.
Just like a chemist observes smell, color, state, temperature, mass, and texture to understand new materials, a molecular gastronomy chef will use similar observations to innovate in the kitchen. These observations, combined with their understanding of how heat affects the chemical structure of food, or how ingredients interact on a molecular level, are integral to the creation of their culinary masterpieces. From frying eggs to the absorption of food in the digestive system, chemistry is deeply involved in the transformation of food from raw ingredients to the finished dish.
Thus, not only is it important for molecular gastronomy chefs to have a deep knowledge of chemistry, but it's essential for their art. It allows them to precisely control the physical and chemical transformations of ingredients, leading to the creation of innovative dishes that are as pleasing to the eye as they are to the palate.

Which of the following is true of penguins?
A. They live in the polar regions of the Northern and Southern hemispheres.
B. They can be found as far north as the Equator.
C. They are ectotherms.
D. They time their reproduction so that eggs hatch during the winter.
E. They are able to fly when disturbed.
A. They live in the polar regions of the Northern and Southern Hemispheres.
Final answer:
Penguins can be found as far north as the Equator, with the Galapagos penguin living near that region (option B). They are not ectotherms but endotherms, and they do not fly as they are flightless birds who are adapted for swimming and diving.
Explanation:
Of the options provided about penguins, B. They can be found as far north as the Equator is true. Penguins primarily live in the Southern Hemisphere, particularly in Antarctica, though not exclusively so. One species, the Galapagos penguin, lives near the Equator. Penguins are endotherms (warm-blooded), which allows them to maintain a stable body temperature despite environmental fluctuations. Therefore, it is incorrect to say they are ectotherms. Regarding their breeding habits, many penguin species time their reproduction so that the chicks are hatched and reared during the warmer months when food is more abundant, not in the winter. Finally, penguins are flightless birds, so they cannot fly when disturbed or under any circumstance. They are well-adapted to swimming and diving instead.

Which of the following would cause only a chemical change with a sugar cube
Answer:
Which would cause only a chemical change in a sugar cube is heating the sugar cube with acid.
Explanation:
The complete question is:
Jolene wants to experiment with sugar cubes. Which of the following would cause only a chemical change with a sugar cube
Burning the sugar cube with a matchstick .Crushing the sugar cube and dissolving it in water .Heating the sugar cube with acid.The addition of acid to sugar (sucrose) is a known reaction that produces the chemical change of this carbohydrate into carbon, by a process of dehydration.
In the reaction of dehydration of sucrose with sulphuric acid - which is exothermic - the acid extracts water from the sugar molecule, producing gases, such as CO₂ and SO₂, which consumes the acid and converts the sucrose into carbon. The chemical reaction is:
C₁₂H₂₂O₁₁ + H₂SO₄ + 1/2 O₂ ----------→ 11C + CO₂ + 12H₂O + SO₂
Sucrose + Sulfuric Ac. + Oxygen → Carbon + Carbon dioxide + water + sulfur dioxide.
This reaction involves only a chemical change of the sucrose, when converted into carbon.
What would happen if you removed a level from the levels of organization?
Answer:If we were to remove just one level of organization all the other levels would fall apart. It would then become very difficult to make any decisions without all the levels put together as one.
Explanation:
Removing a level from the levels of organization in biology disrupts the hierarchical structure that organizes living things. Items were organized from smallest to largest: hydrogen atom, water molecule, skin cell, liver, elephant, wolf pack, tropical rainforest, and planet Earth.
If you remove a level from the levels of organization in biology, it would disrupt the hierarchical structure that organizes living things from the simplest to the most complex. The levels of organization, from the smallest to the largest, are typically categorized as atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, and the biosphere.
Using the provided items, we can organize them from the smallest to the most encompassing as follows:
Hydrogen atomWater moleculeSkin cellLiver (organ)Elephant (organism)Wolf pack (population)Tropical rainforest (ecosystem)Planet Earth (biosphere)These levels were placed in this order reflecting their scale and complexity, starting from the subatomic particles that make up atoms, moving to complex molecules, then to cells which are the basic units of life. Organs are made up of tissues, which are made up of cells. Organisms are individual living entities, populations are groups of the same species, ecosystems comprise living and nonliving components in a particular area, and the biosphere encompasses all ecosystems on Earth.
Chunks of rock and metal from planetary bodies that survive their journey through the atmosphere and fall to the ground are called meteorites and scientists have found over 50,000 on Earth's surface. What is the origin of the majority these meteorites?
A. They are pieces of a planet that have broken off.
B. They are the original materials from which the planets formed.
C. They are bits of our moon that have eroded and fell back to Earth.
D. They are jarred loose from a meteor belt found among the outer planets.
Final answer:
The majority of meteorites are fragments from asteroids and are primitive objects that date back to the formation of the solar system. Some may also originate from impacts on planets like Mars or our Moon.
Explanation:
The majority of meteorites originate from the debris of space, mostly fragments of asteroids, and to a lesser extent, from impacts on Mars or our Moon. Meteorites represent primitive objects that are dated back to the origin of the solar system around 4.5 billion years ago and are considered remnants of the solar nebula from which the solar system formed. These remnants, which include asteroid fragments and possibly pieces from planetary impacts, have managed to survive the fiery journey through Earth's atmosphere and reach our planet's surface.
