Where will the cytoskeleton protein be synthesized?
Cytoskeleton proteins are synthesized in the cytoplasm of the cell, primarily on ribosomes. These ribosomes can be either free-floating in the cytosol or attached to the endoplasmic reticulum (ER), contributing to the synthesis of proteins that may be destined for various cellular functions. After synthesis, cytoskeleton proteins undergo folding and modifications before assembling into structures like microtubules, actin filaments, or intermediate filaments.
Arlobes can be either attached or detached. The allele for attached earlobes is recessive (e) and the allele for detached earlobes is dominant (E). What must be true if a boy is born with attached ear?
If a boy is born with attached earlobes, he must have inherited two recessive alleles (ee), one from each parent. This means that both parents must either be carriers of the recessive allele (Ee) or express the attached earlobe phenotype themselves (ee). Therefore, at least one of the parents must have the recessive allele for attached earlobes.
What is a attached ribosome?
An attached ribosome is a ribosome that is bound to the endoplasmic reticulum (ER) membrane. It is involved in the synthesis of proteins that are either secreted by the cell or inserted into the membrane. These proteins play crucial roles in various cellular functions.
Identify the organisms that exist as either medusa or polyp form?
Jellyfish exist as either a medusa (adult free-floating) or polyp (immature attached) form during their life cycle. Another example is the Portuguese Man o' War, which also has a medusa (floating) and polyp (attached) stage.
What part of the cell are proteins made from?
Proteins are translated from mRNA in ribosomes. They can either be free-floating ribosomes in the cytosol, or attached ribosomes on the rough ER.
The end of the muscle that moves when a muscle contracts?
Histological PerspectiveBoth ends of the muscle are pulled together. This is because each muscle fiber is divided into contractile units called sarcomeres. Each sarcomere is composed of layers of thin and thick filaments, Actin and Myosinrespectively. The thick filaments, myosin, are located in the center of the sarcomere, a region called the A-Band. On either side of each A-Band, is a region called the I-Band. The I-Band is primarily composed of the thin filaments (Actin), although the thin filaments do overlap with the thick filaments within a sub region of the A-band called the zone of overlap.As the muscle contracts the thick filaments pull the thin filaments together on either side, resulting in the apparent contraction of the muscle on both sides.Gross Anatomical Perspective.However, because a muscle is anchored at the origin of the stationary bone while its other end attaches at the insertion of the articulating bone and the net force of the contracting muscle pulls the insertion of the muscle to its origin.It follows that: The correct answer is toward the origin.
When a skeletal muscle contracts the Z lines get further apart?
When a skeletal muscle contracts, the Z lines actually move closer together rather than further apart. This occurs due to the sliding filament mechanism, where actin filaments slide over myosin filaments within the sarcomere. As the myosin heads pull on the actin, the sarcomere shortens, causing the Z lines at either end to approach each other, resulting in muscle contraction. Thus, the overall effect is a reduction in the distance between Z lines during contraction.
Where will the cytoskeleton protein be synthesized?
Cytoskeleton proteins are synthesized in the cytoplasm of the cell, primarily on ribosomes. These ribosomes can be either free-floating in the cytosol or attached to the endoplasmic reticulum (ER), contributing to the synthesis of proteins that may be destined for various cellular functions. After synthesis, cytoskeleton proteins undergo folding and modifications before assembling into structures like microtubules, actin filaments, or intermediate filaments.
What do fish breathe using?
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.
What happens to a muscle contraction if there is an excess amount of either Ca2 plus or ATP present during the contraction?
During muscle contraction the actin heads pull the sarcomere closed
What could cause the brake-lights on a 1990 Volvo to work with the headlights off but not to work when the headlights are turned on?
They are either the wrong bulbs or one of the filaments is burned out. The bulbs should have two filaments. One is illuminated when the lights are on. The other is brighter when the brakes are used.
Earlobes can be either attached or detached. The allele for attached earlobes is recessive and the allele for detached earlobes is dominant. What must be true is a boy is born with attached earlobes?
He has a homozygous genotype
What is the floating ribs not attached to?
Sternum/breast-bone, either directly or not
What is the bridle attached to?
the bridle is attached to the mouth......either of horses or a mule. it is actually used to control the direction to which the whole body moves
What is the problem if you have tail lights but only one brake light?
The tail light/brake light bulb has two filaments. If one of the filaments is broken, you will get either only tail lights, or brake lights. If a new bulb doesn't work, then you have a broken wire or bad connection in your plug-in.
Ccna exam fees?

What is the bit directly attached to?
The bit is directly attached, via bit rings on either side, to the left and right cheekpieces and reins of the bridle.
