while a neuron membrane is depolarizing its __________.
Answers
Given what we know about the depolarization of neurons, we can confirm that while a neuron membrane is depolarizing its sodium gates are fully open.
Throughout the human body, sodium is often used to cause shifts in membrane potentials, as well as a variety of other metabolic processes, due to the electric charge of this ion. One such example is the neuron, which uses a flood of sodium ions to depolarize its membrane.
During depolarization, the membrane potential changes from a negative charge to that of a positive one. This is caused by the rapid flooding of sodium into the cell, which increases the positive charge in the interior of the cell and thus affects the membrane's potential.

As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
Answers
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.

Two brothers have thick hair that grows over their faces and most of their bodies.
This human disorder, called Ambra's Syndrome, shows X-linked dominant inheritance. The
mother of the boys is also affected by Ambra's Syndrome, although her excessive hair growth
occurs in various, scattered patches on her skin rather than a continuous coverage like her sons.
What is the most likely explanation for the patchy expression of hairlessness on the mother's
skin?
Answers
The most likely explanation for the irregular expression of hairlessness on the mother's skin is codominance
Codominance is a biological term to refer to the hereditary pattern that is characterized by:
In the heterozygous state, there is no recessive allele, but both behave as dominant. Codominance is characterized by the manifestation of both characteristics as dominant, without mixing.According to the above, the irregular expression of the lack of hair in the mother is a manifestation of the codominance of the hair gene and the hairless gene that do not mix but are seen independently.

Under the hypothesis of blending inheritance, what color(s) would the offspring of a black cat and a white cat be
Answers
Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY. This theory is not now accepted.
Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.
Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.
Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

what is the difference between ribose and deoxyribose
Answers
Ribose is a 5-carbon simple sugar. The chemical formula of this sugar molecule is H−(C=O)−(CHOH)4−H. This is the prime component of ribonucleic acid strands. It forms ribonucleotides.
Deoxyribose is a hexose sugar and is found in RNA. Deoxyribose binds a phosphate at the 2′ position. deoxyribose has one less oxygen molecule than ribose.
Deoxyribose, on the other hand, is a monosaccharide too. It also has the same 5-carbon formula as that of ribose sugar but loses an oxygen atom. Its chemical formula is H−(C=O)−(CH2)−(CHOH)3−H
