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).

what is the correct equation for photosynthesis?
Answer:
6CO2 + 6H20 ⇒ C6H12O6 + 6O2
Explanation:
Carbon Dioxide + Water ⇒ Glucose + Oxygen
Photosynthesis is the process through which plants prepare their own food in the presence of sunlight in the chloroplast of the cell.
What is Photosynthesis?Photosynthesis is the process of transformation of energy from solar energy (radiation) into chemical energy. The chemical energy is present in the form of chemical bonds present in the glucose molecule (carbohydrate).
The process of photosynthesis is commonly written as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This means that the reactants in the process are six molecules of carbon dioxide and six water molecules, are converted by the light energy (radiation) captured by chlorophyll into a sugar molecule (carbohydrate) and six oxygen molecules, as the products.

What are the two most important driving forces of metamorphism?
A. High heat and pressure
B. Melting and cystallization
C. Deposition and lithification
D.Weathering and accumulation
E.Magma and lava
ne questions
Answer:
Heat and pressure
Explanation:
Metamorphic rocks are found deep underground
The two most important driving forces of metamorphism are high heat and pressure (option A).
These two factors play a significant role in transforming rocks into metamorphic rocks. When rocks are subjected to high temperatures and pressures, the minerals within them undergo changes in their composition, structure, and texture. This process leads to the formation of new minerals and the recrystallization of existing minerals, resulting in the development of distinct metamorphic textures and structures.
The course of transformation doesn't dissolve the stones, however rather changes them into denser, more conservative rocks. Rearrangements of mineral components or reactions with fluids that enter the rocks produce new minerals.

Pleaseeee help!!! (psychology edge) Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explain how the two types of hormones are involved.
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.

The correct sequence for the general adaptation syndrome is:_________
a) Exhaustion phase, alarm phase and resistance phase
b) Alarm phase, resistance phase and exhaustion phase
c) Resistance phase, exhaustion phase and alarm phase
d) Alarm phase, exhaustion phase and resistance phase
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.

membrane from the bloodstream Into the renal You will be injected into the subclavian vein and must

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.
How does the urinary system work?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.
