easch couplet presents the user with 2 alternatives and exclusive sets of character's.

10 couplets should your key have. If you are building a dichotomous key, and you have 10 species to identify. Hence, option D is correct.

A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.

A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.

The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.

Thus, option D is correct.

Heart valves or the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole and the closure of the aortic valve and pulmonary valve at the end of ventricular systole.

Explanation:

The heart tone “lub,” or S1, is caused by the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole.

The heart tone “dub,” or S2 ( a combination of A2 and P2), is caused by the closure of the aortic valve and pulmonary valve at the end of ventricular systole.

Answer:for your journey through the urinary system you must be made small enough to be filtered through the filtration

Explanation:

The urinary system, sometimes referred to as the renal system, manages fluid and electrolyte balance as well as filters and eliminates waste items from the body.

You must be reduced in size to pass through the filtration membrane and into the renal system on your voyage via the urinary system. The subclavian vein will be used as the injection site, and you must first pass through the heart to reach the arterial circulation. You have at least two minutes to unwind as you move through the systemic circulation before you arrive at the renal artery, which supplies the kidney.

Through the artery wall, you can make out the towering, brownish-red kidney. Once within, the kidney's blood arteries get progressively smaller until you reach the afferent arteriole, which feeds into the glomerulus, the filtering organ. Once inside the filter, you position yourself such that you are facing a pore directly. You are quickly carried across the filtration membrane and into the Bowman's capsule region of the nephron. You lower the specimen cup as you proceed to collect your first test sample of filtrate.

You examine the reading from the sample and discover that, with one exception, its chemical makeup is very identical to that of blood. Practically no blood cells exist. You can wait to take your next sample until you get to the Henle loop, or the "hairpin" in correct language. You observe the tubule cells as you proceed along your path because they have numerous thick fingerlike projections that protrude into the tubule lumen from their surface.

This portion of the tubule is relatively small, therefore these microvilli improve the absorptive surface area. You gather your second sample while in the "hairpin". The readout confirms that the filtrate's content is significantly lower and that few nutrients, including glucose and amino acids, are present.

Here, metabolic wastes are substantially more concentrated, and the area is yellow, which denotes the presence of the urochrome pigment. You know you have arrived in the distal convoluted tubule and are seeing the process of secretion when you gradually work your way up from the 'hairpin' and enter into an area where big molecules are being transported into the filtrate.

As you proceed, you notice that the streams are now more agitated and the water level has plummeted. You recall the function of the hormone ADH and assume that the body must have secreted it to save water. You make a sharp right and then plunge straight down into a tube that is being filled with fluid and other tubes. You become aware that you are moving towards the minor calyx in the collecting duct.

You move very calmly into a tube on the other coast after entering a much calmer area. You become aware that you are experiencing a rhythmic downward squeeze as soon as you enter this tube, indicating that you are in the ureter. You know you have arrived to the urinary bladder when you suddenly drop and splash into a sizable sea of urine. As you can see, there is a lot of fluid as the ceiling gets closer to you and the walls start to pull. Suddenly, you are propelled out of the body and into your host's urethra to leave the body.

Therefore, the urinary system, sometimes referred to as the renal system, manages fluid and electrolyte balance as well as filters and eliminates waste items from the body.

We need to find dy/dx at x = 2

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(\dfrac{x-1}{x+3})\\\\=\dfrac{(x+3)\dfrac{d}{dx}(x-1)-(x-1)\dfrac{d}{dx}(x+3)}{(x+3)^2}\\\\=\dfrac{x+3-(x-1)}{(x+3)^2}\\\\=\dfrac{x+3-x+1}{(x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{4}{(x+3)^2}[/tex]

Put x = 2 in above expression

[tex]\dfrac{dy}{dx}|x=2=\dfrac{4}{(2+3)^2}\\\\=\dfrac{4}{25}[/tex]

Hence, the value at dy/dx is [tex]\dfrac{4}{25}[/tex]

Explanation:

G and C are complimentary; T and A are complimentary

Just swap each letter following that rule :)

Answer:

Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.

Answer:

The correct sequence for the general adaptation syndrome is: b) Alarm phase, resistance phase and exhaustion phase

Explanation:

The general adaptation syndrome describes what happens to our body when it is under stress.

The first phase is the Alarm phase. In this stage, the body activates the fight or flight response, causing an increase in adrenaline and cortisol, blood pressure, respiratory frequency, amongst other things that prepare us to react in a situation that we perceive as dangerous.

The second phase is the resistance one. During this phase, the body undergoes a different process that adapts it to manage the stress, with an elevated amount of cortisol and blood pressure.

The third phase is the exhaustion phase. If the stress levels continue to be high, the body passes to this stage. The body is exhausted and cannot keep dealing with stress, which causes mental and physical problems such as anxiety, depression, fatigue, stress-related illnesses, among other symptoms.

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.
