In familial hypercholesterolemia, individuals with two abnormal alleles die of heart attacks in childhood, those with only one abnormal allele typically die as young adults, and those with two normal alleles have normal life expectancies. This exemplifies C. incomplete dominance
In the field of genetics, the phenomenon of incomplete dominance can be described as the one in which the dominant allele does not have the ability to completely mask the recessive allele. As a result, an intermediate species is formed that is different from both the homozygous dominant and homozygous recessive types.
In familial hypercholesterolemia, incomplete dominance is shown by young adults who have one healthy and one abnormal allele. As a result, these young adults are able to survive till a young age. On the contrary, the individuals with both abnormal alleles die during childhood and those with both normal alleles live a normal life.

iii. tobacco smoke
a. i and ii only
b. i and iii only
c. ii and iii only
d. i, ii and iii
The factors that can cause emphysema are air pollution, genetic predisposition and tobacco smoke. The correct option is d.
What is emphysema?Emphysema is a type of lung disease that causes shortness of breath. The air sacs in the lungs (alveoli) are damaged in people with emphysema.
The inner walls of the air sacs weaken and rupture over time, resulting in larger air spaces rather than many small ones.
Emphysema is usually caused by long-term exposure to irritants that damage your lungs and airways.
People who are born with a genetic mutation that causes an alpha-1 antitrypsin deficiency are predisposed to an early form of emphysema as well as liver cirrhosis.

Using cause and effect statement explain the cause of limited cell size
Answer: Cell size is limited due to the inability of very large cells to provide nutrients and water and remove wastes in an efficient manner. The size of a cell is limited by the relationship of the cell's outer surface area to its volume or its surface area-to-volume ratio. Thus,
Explanation:
Large cells can't efficiently supply nutrients, water, and wastes. Surface area-to-volume ratio limits a cell's size.
What causes limited cell size?
The surface volume ratio is the one and only factor that regulates the maximum size of the majority of the cell. The nucleo-cytoplasmic ratio, which controls the range of control of the metabolic ratio and the ratio of surface to volume, places a ceiling on the size of the cell. This ceiling is set by the nucleo-cytoplasmic ratio.
Because they are so little, cells are able to make the most of the surface area to volume ratio they possess. When compared to larger cells, smaller cells have a higher ratio, which means that they are able to transport a greater number of molecules and ions across the cell membrane for each unit of cytoplasmic volume. The reason that cells are so little is because they have to be able to quickly take in nutrients and release waste products.

What type of channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters?.
Voltage gated Ca2+ channels opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters.
Voltage-gated calcium channels are found in the cell membranes of nerve cells and are responsible for regulating the flow of calcium ions into the cell. These channels open in response to an action potential arriving at the axon terminal, and function to allow synaptic vesicles to release neurotransmitters.
Calcium ions are important for many cellular processes, including muscle contraction, secretion of hormones, and cell signaling. When an action potential reaches the axon terminal, it causes the voltage-gated calcium channels to open, allowing calcium ions to flow into the cell. This influx of calcium ions causes the synaptic vesicles to release their neurotransmitters into the synapse, where they can bind to and activate post-synaptic receptors.
The voltage-gated calcium channels are critical for proper nerve function, and any dysfunction of these channels can lead to serious problems. For example, if the channels do not open properly in response to an action potential, the synaptic vesicles will not be able to release their neurotransmitters, and the nerve cell will be unable to communicate with other cells. This can lead to serious problems, such as paralysis.

Skeletal and cardiac muscle cells store calcium in extensive networks of smooth ER.
Cardiac muscles are those that build up the heart. These muscles have the ability of auto-rhythmicity. Thus means that they can perform movements on their own. Cardiac muscles are also called involuntary muscles, because they do not move according to the wish of the individual.
Smooth ER is the one that does not have ribosomes attached on its surface. It acts as a reservoir for storing the calcium ions inside the cell. These calcium ions are transported to the cell organelle by active transport and release by the signals of hormones.

In determining their composition, they were told they are polypetides formed into sphercal shapes which were mostly soluble in water. they concluded that these antibodies were globular protiens.
What is globular protiens?The term "globular protein" is fairly old (dating likely from the 19th century) and is now somewhat obsolete given the hundreds of thousands of proteins and more sophisticated and descriptive structural motif vocabulary. Only by using ultracentrifuges or dynamic light scattering techniques can the globular nature of these proteins be identified without the use of contemporary methods.
By virtue of the protein's tertiary structure, the spherical structure is induced. Apolar (hydrophobic) amino acids are bonded inside the molecule, whereas polar (hydrophilic) amino acids are bound outside. This allows for dipole-dipole interactions with the solvent, which explains why the molecule is soluble.
The free energy released when a protein folds into its native shape is relatively low, which makes globular proteins only weakly stable.
