A woman with color-normal vision, but whose father was color blind, marries a man with normal vision. They are expecting a child

kotegsom [21]

To know what happens here, you need to analyze the alleles.

If the father is color blind and the daughter is not, you can suppose that is a recessive allele.

You can tell she is a carrier only, and because we received one sexual allele from each parent. If they ask you about the gender, we can suppose a cross between Xx and XY being lower x the recessive allele (color-blind vision).

When you draw the Punnett square, you'll found the probabilities are XX, XY, Xx, and xY.

So, you have a 50% chance of having a boy and 25% chance of having a color-blind boy.

You measure levels of Ca2+ in various locations within a motor neuron and a skeletal muscle fiber when the motor neuron is NOT d

gogolik [260]

Answer:

The correct answer is 3: "High levels of Ca2+ are expected to be found within the sarcoplasmic reticulum".

Explanation:

Muscular contraction is a highly regulated process that depends on free calcium concentration in the cytoplasm. Amounts of cytoplasmic calcium are regulated by sarcoplasmic reticulum that functions as a storage of the ion.

When a nerve impulse reaches the membrane of a muscle fiber, through acetylcholine release, the membrane depolarizes producing the entrance of calcium from extracellular space. The impulse is transmitted along the membrane to the sarcoplasmic reticulum, from where calcium is released. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. The calcium channel in the sarcoplasmic reticulum controls the ion release, that activates and regulates muscle contraction, by increasing its cytoplasmic levels. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites, making possible the formation of cross-bridges between actin and myosin filaments. When myosin binds to the uncovered actin-binding sites, ATP is transformed into ADP and inorganic phosphate.

Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.
