Answer:
Glycolysis is the metabolic pathway (process) that converts one molecule of glucose into two molecules of pyruvate. In the process the pathway forms two molecules of ATP and one molecule of NADH from two molecules of ADP and phosphate and one molecule of NADH.
The importance of glycolysis is that it provides the cell with a small amount of readily accessible energy in the form of ATP and it provides the mitochondria with a source of pyruvate. There, the pyruvate can be completely oxidized to CO2 and H2O and form a large amount (~28 molecules) of ATP from ADP and phosphate. More importantly, it provides red blood cells with there only source of ATP (since they have no mitochondria).

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.

The best action humans can take to decrease the effect of harmful growth and reproduction of algae is to:.
Control fertiliser usage; this action will show a high decrease in the effect of harmful growth of algae
How will it work?
The fertilisers are chemical or biological mixtures that provide the essential inorganic and organic nutrients that a soil ordinarily lacks yet that plants need for healthy growth and crop production.
Increased fertiliser use has the potential to contaminate both land and water. Due to the addition of fertiliser minerals to the nearby water body as a result of surface runoff, plants and algae flourish excessively due to the availability of nutrients. Eutrophication is the term for this phenomenon.
As a result, fertilisers should only be used in limited quantities to prevent eutrophication.

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
4 ................................ 625
5 ................................ 312
6 ................................ 156
7 ................................. 78
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.
