Explanation:
In seedcracker finches on a remote island, birds are found with varying bill sizes. Those with larger bills (on average) specialize in cracking hard, thick-walled seeds. Birds with smaller bills (on average) feed on seeds with softer seed coats. If ongoing climate change results in the most of the seeds in the area becoming thich-walled, predict the outcome on the population of seedcracker finches. Select ALL that apply
Answer:answer is b and d
Explanation:
Birds with larger bills (on average) specialize in cracking hard, thick-walled seeds and Birds with smaller bills (on average) feed on seeds with softer seed coats, but if climate change results in most of the seeds in the area becoming thick-walled, then only birds with larger bills will survive.
What is the natural selection in the case of finches?Natural selection selects the best and fittest individuals so that the population or species can grow further, as in this case, where both types of finches are present, but due to climate change, only the seeds with thick walls survived, and the birds that can eat these will survive, while the rest will be removed from the environment.
Hence, birds with larger bills (on average) specialize in cracking hard, thick-walled seeds and Birds with smaller bills (on average) feed on seeds with softer seed coats, but if climate change results in most of the seeds in the area becoming thick-walled, then only birds with larger bills will survive.

Which of the following discoveries does not necessarily support the Theory
of Plate Tectonics?
Select one:
A. Fossils of the same species were discovered in both Scotland and the
Appalachian Mountains,
B. The shape of western Africa is similar to the eastern coastline of South
America
C. Early sonar used in WWII found mid-ocean ridges,
D.. Many different species of dinosaurs were found in the western United
States,
Answer:
answer is c
Explanation:
In 1859, Charles Darwin proposed that differential survival and reduction of individuals would produce changes in species population over time. In other words, the environment acting on variation of individuals within a population would result in an adaptation (an evolutionary process that results in morphological, physiological or behavioral changes at the population level and that increases the probability of the members of that population to survive and their reproductive success). Using a specific example, explain how natural selection explains the theory of evolution. Also include in your explanation and within your example, what are the 4 factors needed for natural selection to act
Answer:
Reproduction, heredity, variation in fitness or organisms.
Explanation:
Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

What do you think the Departure from Normal column means, and why is it important for weather scientists in terms of temperature and precipitation? In your answer, explain what conclusions you can draw about your town from this column.
Answer:
Explanation:
Normal Value is the normal temperature or precipitation for the city on that day in history. This information can help scientists determine whether the conditions that day are typical for the city. For New York, the temperature yesterday was 5 degrees higher than normal. Precipitation for the month was 1 inch below normal.

What is molting????????
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle.
Moulting can involve shedding the epidermis (skin), pelage (hair, feathers, fur, wool), or other external layer. In some groups, other body parts may be shed, for example, wings in some insects or the entire exoskeleton in arthropods.
When water molecules are attracted to one another, the arrangement is
Group of answer choices
an oxygen atom on one molecule to only the oxygen atom on another molecule.
a hydrogen atom on one molecule to either hydrogen or oxygen of another water molecule.
an oxygen atom on one molecule to only hydrogen on another molecule.
a hydrogen atom on one molecule to only a hydrogen on another molecule.
Answer:
An oxygen atom on one molecule to only hydrogen on another molecule.
Explanation:
Water molecules have a polar charge (the oxygen side is more negative than the hydrogen side) so the oxygen side will attract towards the hydrogen side.

Sound is another form of kinetic energy--it's air in motion. space heater- Space heaters work by utilizing convection or radiant heating. Radiant heaters emit infrared radiation into the room that directly heats objects and people who are close to them. One way to generate electricity is to burn solid waste, like the material found in landfills. ... That thermal energy is transformed into electrical energy, usually by turning a turbine. Another energy resource that comes from our garbage is the methane gas that is produced as the waste decays. A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.
Explanation:
under which circumstances do plants take up water by osmosis?
The roots of a plant are the plants lifeline. They reach out into the soil to establish an avenue for the transport of nutrients and water to the rest of the plant. The roots absorb water through osmosis. If the water concentration outside of the plant roots is greater than that of the water concentration in the roots osmosis occurs.
