Interneuronal communication occurs via _______________ messengers that are released from the presynaptic neuron. These are called _____________ and they act by binding to receptors on the postsynaptic neuron. This binding opens ____________ channels, which can either hyperpolarize or depolarize the postsynaptic neuron membrane. This action is kept relatively short by either the decomposition or the ______________ of neurotransmitters from the synaptic cleft.
Answer:
Interneuronal communication occurs via chemical messengers that are released from the presynaptic neuron. These are called neurotransmitters and they act by binding to receptors on the postsynaptic neuron. This binding opens Ion channels, which can either hyperpolarize or depolarize the postsynaptic neuron membrane. This action is kept relatively short by either the decomposition or the reuptake of neurotransmitters from the synaptic cleft.
Explanation:
Neurons are communicated to each other by a process known as synapsis. Synapsis occurs when the presynaptic neuron sends a message to the postsynaptic neuron. Vesicles from the presynaptic membranes are sent carrying the chemical messenger in their interior. This messenger is called a neurotransmitter and is released by exocytose to the synaptic space. Then the neurotransmitter goes forward to the postsynaptic membrane. When it reaches this last membrane, the neurotransmitter binds its receptor triggering an answer and opening ion channels. This binding produces depolarization of the cell called excitatory postsynaptic potential. If the signal molecule keeps being in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space by enzymatic degradation/deactivation or Reuptake. There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use.
Scenario 1
When you think of the American Southwest, you probably think of cacti, both big and small. If you were to
visit the American Southwest today, you might be disappointed with the lack of variation among cactus
species, especially right off the major highways. In 1926, Route 66 was the nation's first major highway to
allow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento of
their travels. Many people would pull over and begin looking for their own living souvenir. Since many of the
tourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make a
conscious decision about what type of cactus they should dig up. The cacti with too many spines were seen
as too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with too
few spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that was
between these two extremes. Over the last century, the phenotypic variation within these small cacti has
changed (at least in areas accessible by these highways).

Answer and Explanation:
The cell looks like a prokaryotic cell. A prokaryotic cell might be recognized by the presence of flagellates used to move (the four long filaments located posterior to the cell). There are also many pili surrounding the cell wall (the small little filaments). There are almost no organelles. There is a circular DNI molecule concentrated in a nucleoid (which seems to be the grey oval in the middle of the cell). Prokaryotic cells also have different compartments that depend on the type of cells, such as chlorosome, carboxysome, phycobilisome, and others (which might be the dark spiral circle in the anterior part of the cell). Two differences with the cell of an onion peel are that the onion peel cell has its genetic material surrounded and protected by the nucleus membrane, whereas the prokaryotic cell lacks a delimitated nucleus. Also, the onion peel cell has a hexagonal shape and lacks flagellates and pili, unlike the prokaryotic cell, which uses the to move. The onion peel is a multicellular structure, while the prokaryote is a one-celled organism. There should always be a cover glass over the cell or tissue we are looking at. Fasten the slide with the stage clips. Move the lens carefully in order not to damage it or the slide. Do not touch or clean the lens with the fingers and try not to stain them.Bacterial disease is caused by the multiplication of bacteria in a patient. How do pathogenic bacteria harm a patient?
Answer:
Host Susceptibility
Resistance to bacterial infections is enhanced by phagocytic cells and an intact immune system. Initial resistance is due to nonspecific mechanisms. Specific immunity develops over time. Susceptibility to some infections is higher in the very young and the very old and in immunosuppressed patients.
Bacterial Infectivity
Bacterial infectivity results from a disturbance in the balance between bacterial virulence and host resistance. The “objective” of bacteria is to multiply rather than to cause disease; it is in the best interest of the bacteria not to kill the host.
Host Resistance
Numerous physical and chemical attributes of the host protect against bacterial infection. These defenses include the antibacterial factors in secretions covering mucosal surfaces and rapid rate of replacement of skin and mucosal epithelial cells. Once the surface of the body is penetrated, bacteria encounter an environment virtually devoid of free iron needed for growth, which requires many of them to scavenge for this essential element. Bacteria invading tissues encounter phagocytic cells that recognize them as foreign, and through a complex signaling mechanism involving interleukins, eicosanoids, and complement, mediate an inflammatory response in which many lymphoid cells participate.
Genetic and Molecular Basis for Virulence
Bacterial virulence factors may be encoded on chromosomal, plasmid, transposon, or temperate bacteriophage DNA; virulence factor genes on transposons or temperate bacteriophage DNA may integrate into the bacterial chromosome.
Host-mediated Pathogenesis
In certain infections (e.g., tuberculosis), tissue damage results from the toxic mediators released by lymphoid cells rather than from bacterial toxins.
Intracellular Growth
Some bacteria (e.g., Rickettsia species) can grow only within eukaryotic cells, whereas others (e.g., Salmonella species) invade cells but do not require them for growth. Most pathogenic bacteria multiply in tissue fluids and not in host cells.
Virulence Factors
Virulence factors help bacteria to (1) invade the host, (2) cause disease, and (3) evade host defenses. The following are types of virulence factors:
Adherence Factors: Many pathogenic bacteria colonize mucosal sites by using pili (fimbriae) to adhere to cells.
Invasion Factors: Surface components that allow the bacterium to invade host cells can be encoded on plasmids, but more often are on the chromosome.
Capsules: Many bacteria are surrounded by capsules that protect them from opsonization and phagocytosis.
Endotoxins: The lipopolysaccharide endotoxins on Gram-negative bacteria cause fever, changes in blood pressure, inflammation, lethal shock, and many other toxic events.
Exotoxins: Exotoxins include several types of protein toxins and enzymes produced and/or secreted from pathogenic bacteria. Major categories include cytotoxins, neurotoxins, and enterotoxins.
Siderophores: Siderophores are iron-binding factors that allow some bacteria to compete with the host for iron, which is bound to hemoglobin, transferrin, and lactoferrin.

Genetic mutation is most likely to cause differences in the population. Therefore, option "C" is correct.
What is a genetic mutation?A prominent change in the sequence of the DNA is known as a genetic mutation. Mutation can be useful and nonsense. Mutation can alter the function of the DNA gene. To understand the genetic mutations, the sequence of the DNA should be known.
The types of genetic mutations are frameshift mutation, insertion and deletion mutation, translocation mutation, and substitution mutation. Albinism can be genetically transferred to the offspring. Both parents should carry the gene responsible for the albinism in oculocutaneous albinism.
Therefore, Albinism occurs when both parents contribute homozygous genes to offspring.

What two body systems will work together to provide cells with energy?
A. Excretory and Digestive, because the nutrients from the digested food will be sent to the excretory to be delivered out as waste products.
B. Digestive and Muscular, because the nutrients from the digested food will be used immediately by the muscles for energy.
C. Respiratory and Excretory, because the oxygen will be transported to the cells so that wastes can be delivered out as a waste production.
D. Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Answer:
Answer:
The correct answer for the first question would be B) the respiratory and circulatory systems.
Respiratory system is a set of organs which help in exchange of gases in the body. They bring oxygen from outside into the body and release carbon dioxide from inside the body to outside world. The exchange of the gases takes place at alveolar site (or gills in aquatic animals).
The circulatory system then carries this oxygen (mixed in blood) from gas exchange site to all the cells of the body. In addition, it also brings carbon dioxide (waste product of cellular respiration) from all the cells to the gas exchange site (respiratory system).
The correct answer of the second question would be C)the digestive and circulatory systems.
Digestive system helps in breaking down of macro-molecules (such as starch, polypeptide, fats) into smaller units (such as glucose, fructose, amino acids) as well as absorption of the same.
Nutrients from the absorptive site (usually small intestine) are then transported to the entire body with the help of blood through capillaries and arteries that is, circulatory system.
Explanation:
Body systems that will work together to provide cells with energy are:-Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Digestive system will breakdown complex macromolecules into micro molecules which are then transferred into blood.Blood or Cardiovascular system will carry these micro nutrients to different parts of the body Describe digestive system?It is system that include organs that take in food and liquids and break them down into substances that the body can use for energy.
Describe cardio vascular systemThe circulatory system or cardiovascular system pumps blood from the heart to the lung to get oxygen.

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals (RR), 257 brown sided individuals (Re) and 557 tan-sided individuals orr). Calculate the following:_______.
a. What is the allele frequency of the Rallele (o)?
b. What is the allele frequency of the rallele (a)?
Migration season comes and 200 of the red-sided individuals leave the nosulation before mating occurs.
c. After migration season what is the new allele frequency of the Rallele (0)?
d. After migration season, what is the new allele frequency of the rallelelo?
e. Which mechanism of evolution (natural selection, genetic drift, or gene flow) caused the allele frequencies to change?
Answer:
a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1049 / 2420 = 0.433
b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1371 / 2420 = 0.567
c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 649 / 2020 = 0.321
d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 1371 / 2020 = 0.679
e) migration is gene flow
Explanation:
Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).

Answer:
Please find the answers to numbers 10 and 11 of the attached image below.
Explanation:
10. This question lists the stages of mitosis namely: prophase, metaphase, anaphase, and telophase. The major events that take place in each of these stages are as follows:
A) PROPHASE:
- the supercoiled chromosomes known as chromatin begins to condense making it visible.
- spindle begins to emerge from the centrosome organelle.
- Nuclear envelope begins to break down in order to expose the chromosomes in the nucleus.
B) METAPHASE:
- The chromosome are aligned at the cell plate i.e. the equator/middle of the cell.
C) ANAPHASE:
- The sister chromatids of each chromosome i.e. replicated chromosomes are pulled apart at the centromere by spindle microtubules to the opposite poles of the cell.
D) TELOPHASE:
- Chromosomes at opposite poles begin to decondense into chromatin.
- The nuclear envelope reforms around the chromosomes
11) Cytokinesis is the process that occurs after mitosis (nuclear division). It is the process whereby the cell whose chromosomes are now separated into opposite poles divide into two. In other words, a cell divides into two in the cytokinesis stage.
