Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?​

Answers

Answer:

The rate of transpiration would decrease

Explanation:

the petroleum jelly would block the stomata of the leaves resulting in decreased transpiration rates

Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.

What is transpiration?

Transpiration exists the procedure of water movement via a plant and its evaporation from aerial parts, such as leaves, stems, and flowers. Water exists essential for plants but only a small amount of water brought up by the roots is utilized for growth and metabolism. The remaining 97–99.5% exists lost by transpiration. An example of transpiration exists when a plant absorbs water in its roots.

Hence, Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.

Los insectos polinizadores son especies clave en muchas comunidades que interacción interespecífica se da entre estos insectos??

Answers

Answer:

Competencia interespecífica

Explanation:

Los polinizadores son organismos esenciales para el equilibrio de las comunidades silvestres y el mantenimiento de la biodiversidad existente en el planeta. Los insectos (especialmente las abejas) representan el grupo de polinizadores más importantes, estos organismos consumen el néctar como alimento y simultáneamente son utilizados por plantas para reproducirse mediante el trasporte del polen de una flor a otra. Los insectos polinizadores usualmente visitan muchos diferentes tipos de plantas y, a su vez, estas plantas son polinizadas por diferentes grupos de insectos polinizadores. Como consecuencia de esto último, entre polinizadores se establece una competencia interespecífica por un recurso (es decir, el polen) el cual a priori podría considerarse limitado. Sin embargo, ha sido demostrado que las redes e interacciones entre plantas y polinizadores están organizadas de tal modo que la competencia interespecífica entre polinizadores se encuentra reducida drásticamente, siendo incluso beneficiosas para las especies que la componen. Estos resultados se encuentran soportados por el análisis de información a campo la cual demuestra como redes entre polinizadores y plantas son similares en diferentes ecosistemas/continentes y también porque cuando tales conexiones gozan de buena salud se observa un aumento de la biodiversidad en las comunidades ecológicas.

How does the color adaptation help fish residing in the coral reefs?

Answers

Answer:

Fish found in coral reefs also have bright coloring to help with mating or camouflage. Due to the wide variety of prey found in coral reefs, the fish have developed a generalized feeding structure to take advantage of the biodiversity. Lastly sessile animals, such as coral, have adapted toxins to keep away predators.

Explanation:

Answer:

Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiforms) , can change their skin coloration to match the surrounding habitat. Fish can also have disruptive markings to hide body parts
