Insulin is a protein hormone that is produced and processed through the endomembrane system of pancreatic beta cells. What method of membrane transport is most likely used to export insulin from the beta cells
exocytosis is the method.
Exocytosis is the process by which cells move substances from the intracellular to the extracellular fluid. Exocytosis occurs when vesicles fuse with the plasma membrane and allow their contents to be released extracellularly.
Examples of exocytosis include the Transport of glucagon from the pancreas to the liver. It is processed there to facilitate absorption into the bloodstream. Transport of protein-filled vesicles from T cells to virus-infected cells
Exocytosis excretes secretory vesicles containing nanoparticles (or other chemicals) from the cell membrane to extracellular locations. It is an energy consumption process. Generally, these membrane-bound vesicles contain soluble proteins, membrane proteins, and lipids that are secreted into the extracellular environment.

Which type of mutation is seen in a sperm cell but not in a skin cell?
Answer:
An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.
Explanation:
when a skin stem cell harbors a cancer-driving mutation, it becomes more likely to generate two specialized skin cells when it divides. Over time, the mutated skin stem cell fails to renew itself and turns into cells that eventually slough off, allowing the skin to expel mutated cells as needed.
Errors in DNA copying during cell division and development can cause new mutations — called de novo mutations — at any time from the moment of conception. Mutations that occur in the germ line — the cells that develop into sperm or eggs — can be passed on to the next generation and, perhaps, cause disease in children.

Continental drift states that continents moved ____ to their current location
Wegener proposed the hypothesis of continental drift, which suggested that continents are in constant motion on the surface of Earth. Over time Pangaea began breaking apart, and the continents slowly moved to their present positions.
What is Continental Drift ?The theory of continental drift is most associated with the scientist Alfred Wegener.
Wegener's continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.Learn more about Continental Drift here:

C-14 half-life is the time it takes for half of the isotope mass to decay into its daughter form. Line graphs are the best way to represent data about half-lives and the amount of isotope (gr).
What is Carbon 14?Carbon 14, also known as radiocarbon, is a radioactive carbon isotope.
Isotopes are the atoms of the same element -carbon- that vary in neutrons and, hence, in their massic number. They are alternative forms of the same element.
The radioactive C14 nucleus contains 6 protons and 8 neutrons and has a half-life of 5730 years.
The term half-life is a reference. It means that an organism that has been dead for 5730 years has half the C14 amount or concentration than the same organism had when it was alive.
In other words, the half-life is the time it takes for half the mass of this isotope to become its daughter form.
Knowing the half-life of an element is useful to determine the age of the dead matter.
C14 is used in radiocarbon dating techniques or methods to estimate the age of fossils. This is a reliable technique used for dating organic samples that are less than 50,000 years old.
An easy way of representing the change in mass of the isotope through the years is to make a line graph, which is easy to interpret and compare the information.
In this example, our line graph must represent the number of half-lives related to the amount of parent isotope in grams.
The table details the years and the amount of isotope. So, by kowing the half-life of C-14, we can get how many half-lives there are.
5,700 years ---------- 1 half-life
11,400 years--------- X = 2 half-lives ⇒ (5700 x 2) or (11,400/5,700)
17,100 years -------- X = 3 half-lives ⇒ (5700 x 3) or (17,100/5,700)
22,800 years ------ X = 4 half-lives ⇒ (5700 x 4) or (22.800/5,700)
28,500 years ------ X = 5 half-lives ⇒ (5700 x 5) or (28,500/5,700)
34,200 years ------ X = 6 half-lives ⇒ (5700 x 6) or (32,200/5,700)
39,900 years ------ X = 7 half-lives ⇒ (5700 x 7) or (39,900/5,700)
45,600 years ------ X = 8 half-lives ⇒ (5700 x 8) or (45,600/5,700)
51,300 years ------- X = 9 half-lives ⇒ (5700 x 9) or (51,300/5,700)
Now, we can make a new table,
Number of half-lives Carbon-14 (g)
0 ..............................10,000
1 ...............................5,000
2................................2,500
3 ................................1,250

8 ................................. 39
9 ................................. 20
Finally, we can make the line graph using the data of this new table. You will find it in the attached files.
In conclusion, the best graph you can make is a line graph, and if they ask you to graph the number of half-lives and give you the number of years, you can just make the conversion using the half-life of the isotope.

What type of plant undergoes self-fertilization to produce some offspring that are identical to the parent and some that are different
Hybrid plants
What is self-fertilization between hybrid plants?Pollen from the same plant travels to the ovule or stigma of a flower (in flowering plants) in a process known as self-pollination (in gymnosperms). In autogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from the microsporangium to the ovule within a single (monoecious) gymnosperm. In geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant. Some plants contain defenses against autogamy, like cleistogamy, which prevents flowers from opening, or moving stamens that touch the stigma. When two distinct plant species are self-pollinated and the resulting seed is grown, a hybrid plant is created. A hybrid is the plant that emerges from those two types of seeds. Commercial self-pollination is done to pass on some sort of desirable trait from each original variety to the progeny. The term "selfing," which is frequently used as a synonym, refers to other forms of self-fertilization as well as self-pollination.

how would the nervous system function be affected if both the presynaptic and postsynaptic neurons at every synapse had both synaptic vesicles and neurotransmitter receptors
Small, electron-lucent vesicles known as synaptic vesicles (SVs) are grouped at presynaptic terminals. They hold neurotransmitters and exocytosis, which is stimulated by calcium, releases them. After exocytosis, SVs are formed locally at the terminals.
From the presynaptic cell with synaptic vesicles to the postsynaptic cell with neurotransmitter receptors, a signal always moves in one direction across the chemical synapse. The correct routing of nerve signals throughout the body is guaranteed by this one-way communication.A signal is transmitted from one neuron—the presynaptic, or sending, neuron—to another neuron—the postsynaptic, or receiving, neuron—at the synapse, increasing or decreasing the likelihood that the postsynaptic neuron will fire its own action potential.The stimulation causes a sensory neuron to go into an action potential, which alters the motor neuron's potential.

When the sarcomere contracts and shortens,D) the A band stays the same.
When a sarcomere contracts, the Z strains flow nearer together and the I band receives smaller. The A band remains equal width and, at full contraction, the skinny filaments overlap. Whilst a sarcomere shortens, some areas shorten while others live the equal length.
At some stage in muscular contraction, the myosin heads pull the actin filaments closer to one another ensuing in a shortened sarcomere. while the I band and H sector will disappear or shorten, the A band length will continue to be unchanged.
A sarcomere is described as a distance between the Z-strains. The Z-strains are pulled closer together for the duration of contraction and move in addition apart in the course of relaxation. The Z-traces are closer for the duration of contraction because actin and myosin interplay generates pass-bridges, which slide the myofilaments over every other.

Which was a result of the human genome project
Answer:
Anatomy
What did the Human Genome Project accomplish?
In essence, it served as a standard for how a human genome appears. One of the first stages in determining if a mutation causes an illness is realizing that there IS a mutation. In order to compare it to "regular" human DNA sequences, we completed the human genome project. Similar to this, a human genome sequence is required in order to compare a human genome or gene to that of a dog or a fruit fly. It essentially changed us from doing genes one at a time to performing them in bulk. You can quickly trace a novel mutation or gene back to the reference genome to determine its location, typical sequence, etc.
Neanderthal genome sequencing is a nice illustration of this. In the absence of a reference genome to match it to, it was just a collection of random sequences. They were able to align and compare the reference human genome to determine precisely how humans vary from Neanderthals. That's a fascinating and significant piece of study that would not have been possible without the creation of a high-quality human reference genome.

Explain/describe how a presynaptic neuron causes an electrical signal on a postsynaptic neuron, when they do not actually touch.
The action potential causes information to be transmitted from the axon of the first neuron (presynaptic neuron) to the dendrites or cell body of the second neuron (postsynaptic neuron) by secretion of chemicals called neurotransmitters.
How do synaptic transmissions occur?Synapse is the junction between neurons where information gets exchanged.The axon of the presynaptic neuron does not actually touch the dendrites of the postsynaptic neuron and is separated from them by a space called the synaptic cleft. Stimulation of the presynaptic neuron to produce an action potential causes the release of neurotransmitters into the synaptic cleft.Neurotransmitters are stored in small vesicles located in knoblike structures on the axon tips.Most of the released neurotransmitters bind with molecules at the receptors on the dendrites of the postsynaptic neuron.The combination of the neurotransmitter molecules to receptor cell molecules in the postsynaptic cell membrane produces a change of potential in the postsynaptic cell membrane called the postsynaptic potential (PSP).Thus a signal is caused on a postsynaptic neuron.Learn more about neuron here:

As Phase 1 of the action potential is initiated, the membrane is _____. This is caused by the ______ of ________ ions
As Phase 1 of the action potential is initiated, the membrane is repolarized. This is caused by the efflux of K+ ions.
Repolarization of Neurons
Repolarization is the process of return of the membrane potential to the negative value before depolarization. During depolarization, the membrane potential becomes a positive value which is returned to a negative value during repolarization.
During repolarization, the sodium channels close and the voltage-gated potassium channels open up. This reduces the permeability of the membrane to the sodium which causes the decline in the entry of sodium ions. During this time the voltage-gated potassium channels are opened up and the potassium ions come out. This restores the negative membrane potential of the cell membrane.
The return of a negative charge from a positive charge lasts only for a brief moment. The process lacks only a few milliseconds. Various channels involved in repolarization are A-type channels, Ca2+ activated K+ channels, delayed rectifiers, etc.
