The shells of some marine snails are highly variable, with some snail shells being solid and others having stripes. Predation by

birds is a major source of mortality for the snails. Scientists studying these snails found that while 47 percent of the snail population was striped, 56 percent of the snails eaten by birds were striped. What could scientists conclude about the snails?

Answer:

Birds have preference to striped snails

Explanation:

The total number of snail with stripes is lesser in number as compared to the total number of snails with solid or no color. Despite this, the birds prefer to feed on snail species that are in minority to the total snail population.  

This represents likeliness of birds to feed on striped snails which constitutes nearly 56 percent.

The two most abundant elements in the oceans are sodium and chlorine. Together they make a salt, halite. Sodium is dissolved in
antoniya [11.8K]

Answer:

Volcanic gases. (Ans A)

Explanation:

Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.

In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.

Si todas las células del organismo reaccionaran cómo lo hacen las del higado, se esperaría que ?
Marat540 [252]

Answer:

Si todas las células reaccionaran como el hígado, cada una tendría la capacidad de producir proteínas, colesterol, almacenamiento y liberación de glucosa, procesaría la producción de hemoglobina y amoníaco en la urea, purificaría las drogas y los desechos, regularía la coagulación, produciría los factores necesarios en la respuesta inmune e intervendría en la formación de bilirrubina, principalmente, sin embargo, debe tenerse en cuenta que una de las funciones principales es el suministro de energía, si cada célula tuviera reservas de glucosa por momentos de estrés, rápida regeneración celular ante las lesiones, las células no tendrían la capacidad de tener una adaptación específica de sus funciones y los procesos que son básicos para el funcionamiento humano serían destruidos, como un eritrocito cuya función es el transporte de oxígeno, no lo haría ser viable si se dedica a producir glucosa porque su estructura debería adaptarse a otra y sin oxígeno el cuerpo no vive, por lo que sería caótico que los sistemas sí no tienen una adaptación específica y son las mismas, aunque las reacciones hepáticas son vitales, requiere el apoyo de otros órganos con diferentes funciones para que estas tengan lugar, es de resaltar que el hígado tiene una respuesta rápida y efectiva ante el estrés, busca recursos para poder mantener funcionando muchos sistemas, si las células se adaptarán con la misma rapidez, se evitaría la aparición de muchas enfermedades.

Sound waves travel through gas liquid and solids A) True B) False
Novay_Z [31]

Answer:

True.

Explanation:

  • Sound is a form of Energy that produces a sensation of hearing in our ears.
  • Sound is produced as a result of vibration produced in a body.
  • Sound energy is transmitted from one place o other place by wave motion.
  • When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
  • During vibration, they collide with the surrounding particle and transfer some energy to them.
  • They then start vibrating faster and transferring  energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
  • Thus, particles are an important factor in propagation of sound.
  • Sound cannot travel in vacuum.
  • It requires a medium to travel from one point to another.
  • A sound can travel in all medium, solids, liquids and gases as all of these have particles.
  • The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest  in solids.
