Answer:
A. nucleic acids
Answer:
A. nucleic acids
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.

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.

Answer: the second one
Explanation:
Si usted sitúa un grupo de plantas verdes (que realizan fotosíntesis) dentro de un ambiente rico en CO2 (dióxido de carbono) con el carbono marcado radiactivamente, es decir, puedo seguir el rastro del carbono. ¿En qué moléculas espera encontrar la marca al interior del cuerpo vegetal?
Answer: Esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.
Explanation:
La fotosíntesis es un proceso utilizado por las plantas y otros organismos fotoautótrofos para convertir la energía de la luz en energía química que, a través de la respiración celular, puede utilizarse para llevar a cabo distintas actividades metabólicas. Esta energía química se almacena en moléculas de carbohidratos, como los azúcares, que se sintetizan a partir de dióxido de carbono y agua. También se libera oxígeno como producto de desecho.
La energía de la luz es absorbida por unas proteínas llamadas centros de reacción que contienen pigmentos verdes de clorofila. En las plantas, estas proteínas se encuentran en el interior de unos orgánulos denominados cloroplastos, que son los más abundantes en las células de las hojas, mientras que en las bacterias están incrustadas en la membrana plasmática. En estas reacciones dependientes de la luz, se utiliza una parte de la energía para despojar de electrones a sustancias adecuadas, como el agua, produciendo gas oxígeno. El hidrógeno liberado por la ruptura del agua se utiliza en la creación de otros dos compuestos que sirven como almacenamiento de energía a corto plazo, permitiendo su transferencia para impulsar otras reacciones: estos compuestos son el nicotinamida adenina dinucleótido fosfato reducido (NADPH) y el adenosín trifosfato (ATP), la "moneda energética" de las células.
El almacenamiento de energía a largo plazo en forma de azúcares se produce mediante una secuencia posterior de reacciones independientes de la luz denominada ciclo de Calvin. En el ciclo de Calvin, el dióxido de carbono atmosférico se incorpora a compuestos de carbono orgánico ya existentes, como la ribulosa bifosfato (RuBP). Utilizando el ATP y el NADPH producidos por las reacciones dependientes de la luz, los compuestos resultantes se reducen y se eliminan para formar más carbohidratos, como la glucosa.
Entonces, si el carbono en la molécula de dióxido de carbono (CO2) se encuentra marcada radiactivamente, esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.
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.

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.

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.
