Answer:
In a population, the sum of the relative frequencies of all alleles for a particular trait is equal to 100 percent. equal to the number of alleles for the trait
Explanation:
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
Explanation:
1). Bats have echo location to sense prey to catch
2.)bearded dragon has a frill to expand. this is used to scare or warn predators
3.) cacti have thick skin to store water for long periods of time
4.)squids have inc sacks to spray predators to give a chance to flee
5). many amphibians have webbed feet to travel better in water
Sickle cell anemia is a genetic condition that distorts the shape of the hemoglobin. This reduces the capacity of the red blood cells to carry oxygen. Another effect is that the distorted red blood cells come together forming a heavy and compact collection of cells that can block the flow of blood. The sedimentation rate is increased by sickle cell anemia.
La troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.
En la capa de la troposfera, que es la capa más baja de la atmósfera, hay vapor de agua, dióxido de carbono, metano y algunos otros gases que son responsables de la absorción de la radiación infrarroja. Parte de la radiación infrarroja se escapa al espacio, pero una parte es detenida y absorbida por los gases de efecto invernadero presentes en la atmósfera.
Esta absorción de radiación infrarroja por los gases de efecto invernadero contribuye a un aumento de la temperatura de la superficie de la tierra y de la atmósfera. Entonces, podemos concluir que la troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.
