Clark's eyes are blue in color. However, both his parents have eyes that are brown in color. According to the dominant-recessive
Zepler [3.9K]

Answer:

Both parents are heterozygous for the trait. They must be carriers of the recessive gene that codes for blue eyes.

Explanation:

Let us assume that the dominant gene codes for brown eyes while the recessive gene codes for blue eyes. We can suggest that both parents are carriers of the recessive gene. They both express brown eyes because they also have a dominant gene that codes for brown. Clark inherited one recessive allele from each parent, so he expresses blue eyes. The couple has a 75% probability of getting a brown-eyed child, while the probability of getting a blue-eyed child is 25%.

How many items is the brain capable of recording each day?
choli [55]
There is no defined limit on the capacity of the brain. The brain's capacity cannot be measured as it is not subject to a defined "space" where the memory is kept, and it is not such that each neuron is responsible for a single memory. The brain has complex mechanisms of memory storage, that even improve if trained.

This is the unequal distribution of ions across a cell membrane.
Nady [450]

Answer:

Concentration gradient

Explanation:

Concentration gradient of the ions across the membrane generates the membrane resting potential.

Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
