Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it is different from simple

diffusion.
Biology

Vilka [71]3 years ago
4 0

Answer:

1. Both facilitated diffusion and simple diffusion move substances according to the concentration gradient.

2. Facilitated diffusion uses membrane transport proteins while simple diffusion does not use them.  

Explanation:

Both facilitated and simple diffusions are the passive processes. This means that these two processes do not use the energy to transport substances. Rather concentration gradient of the substance moves them spontaneously. Therefore, both the processes move substances from higher to lower concentration.  

However, facilitated diffusion uses channels and carrier proteins to move the polar and charged particles that cannot diffuse freely across the membrane.  channels and carrier proteins are the membrane proteins. Simple diffusion does not involve membrane transport proteins.

What are the sequence of steps that includes the image on the retina
jonny [76]

Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.

Explanation:

Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.

From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.

From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.

Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.

Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.

The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.

An individual homozygous dominant for the thumb shape mates with an individual homozygous recessive for thumb shape. What are th
natulia [17]

Answer:

A punnet square can be described as a diagram which is made to check the outcomes of a cross.

To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:  

        t              t

T    Tt            Tt

T    Tt            Tt

The results of the punnet square depict that:

Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.

Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.
