Answer:

Lamarck creía que la evolución era una consecuencia de la presión ambiental mientras que Darwin expresó que el mecanismo de evolución es la selección natural

Explanation:

Lamarck desarrolló una teoría en la que propuso que los organismos evolucionaban como una consecuencia de la influencia ambiental y que los cambios fenotípicos causados por el ambiente podía ser trasmitidos a través de generaciones. Por otra parte, Darwin desarrollo una teoría en la cual las especies evolucionan a través de un proceso que él denominó selección natural (supervivencia del más apto) : aquellos organismos mejor adaptados a su ambiente tendrán más chances de sobrevivir y de reproducirse, pasando sus genes a la siguiente generación. En relación al cuadro comparativo, Lamarck creía que las jirafas se adaptaban a su ambiente para sobrevivir, mientras que Darwin propuso que aquellas jirafas que mejor se adaptaban a un ambiente cambiante tenían más chances de sobrevivir. Lamarck también creía en la idea del uso y desuso de órganos: las jirafas con el tiempo podía desarrollar cuellos más largos estirándose para alcanzar las hojas de los árboles de copas más altas y transmitían esta característica a su progenie, mientras que Darwin propuso que aquellas jirafas con cuellos más largos tenían más chances de sobrevivir que las que tenían cuello corto (selección natural), y las jirafas de cuello largo transmitían este rasgo a su descendencia (descendencia con modificación). Lamarck creía en la idea que las especies no poseen un antecesor común, mientras  que Darwin creía que todo el árbol de la vida está conectado a través de antepasados comunes. Finalmente, Lamarck pensaba que las especies no podían extinguirse, mientras que Darwin propuso la idea que las especies se extinguen y surgen otras nuevas a través de procesos de radiación adaptativa.

Answer:

in the epicenter

Explanation:

In a Venn Diagram that compares and contrasts the different characteristics or features of the produced plants, "cloning" would be in the epicenter. This is because through the process of "cloning" you are basically copying the core genetic makeup of the plant and creating a brand new plant that shares all of the exact same characteristics and features as the plant's whose genetic makeup was used as a baseline.

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do
den301095 [7]

Answer:

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

Hope this helps:)

Describe how each of these 4 processes can affect salinity. Are they increasing or decreasing the salinity?
Charra [1.4K]

Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.

Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.

Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.

Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.

Hope this helps!
