Current price of stock: $58.75 per share

Stock companies price per transaction: $12.99

What is your net profit from each stock transaction?

Answers

Answer: Net profit from each stock transaction:

First, calculate the cost of purchasing the 1000 shares of Nike:

1000 shares x $24.50 per share = $24,500

Then, calculate the revenue from selling the 1000 shares of Nike:

1000 shares x $39.75 per share = $39,750

The total cost of the stock transaction is:

$24,500 + $9.99 = $24,509.99

The total revenue from the stock transaction is:

$39,750 - $9.99 = $39,740.01

Therefore, the net profit from each stock transaction is:

$39,740.01 - $24,509.99 = $15,230.02

Net profit from each stock transaction:

First, calculate the cost of purchasing the 800 shares of Panda Express:

800 shares x $13.50 per share = $10,800

Then, calculate the revenue from selling the 800 shares of Panda Express:

800 shares x $23.25 per share = $18,600

The total cost of the stock transaction is:

$10,800 + $10 = $10,810

The total revenue from the stock transaction is:

$18,600 - $10 = $18,590

Therefore, the net profit from each stock transaction is:

$18,590 - $10,810 = $7,780

Net profit from each stock transaction:

First, calculate the cost of purchasing the 1200 shares of Wal Mart:

1200 shares x $35.50 per share = $42,600

Then, calculate the revenue from selling the 1200 shares of Wal Mart:

1200 shares x $58.75 per share = $70,500

The total cost of the stock transaction is:

$42,600 + $12.99 = $42,612.99

The total revenue from the stock transaction is:

$70,500 - $12.99 = $70,487.01

Therefore, the net profit from each stock transaction is:

$70,487.01 - $42,612.99 = $27,874.02

Question 1: How does increasing the size of the habitat affect carrying capacity? Explain your answer. Recall the scenarios: 0–15 years, Little land; 15–30 years, Moderate land; 30–45 years, Ample land.

Answers

Increasing the size of the habitat can increase the carrying capacity. Carrying capacity is the maximum population size that a particular environment can sustain, and it depends on factors such as resources, predation, and competition.

In general, larger habitats have more resources available, which can support a larger population size. In the scenarios presented, the carrying capacity is expected to increase as the land availability increases.

In the 0-15 years scenario, there is little land available, which can limit the resources available for the population, resulting in a lower carrying capacity. In the 15-30 years scenario, there is moderate land available, which can support a larger population size. In the 30-45 years scenario, there is ample land available, which can support the largest population size of the three scenarios.

However, it's important to note that the relationship between habitat size and carrying capacity is not always linear and can be influenced by other factors such as predation and competition.

claim 3: something about the air changes.

Answers

Based on scientific evidence, the claim that is least convincing is claim 1: "The amount of incoming energy from the sun changes."

While it is true that the amount of incoming solar radiation can affect temperature, it is not the primary driver of temperature changes during El Nino years. The changes in temperature are largely due to changes in oceanic and atmospheric circulation patterns, which are influenced by the warming of the tropical Pacific Ocean. Therefore, claim 2 or claim 3 may be more convincing in explaining why Christchurch's air temperature is cooler than usual during El Nio years.

El Niño is a natural climate phenomenon that occurs in the Pacific Ocean. It is characterized by unusually warm ocean temperatures in the central and eastern tropical Pacific, which can have significant impacts on weather patterns around the world. El Niño events typically occur every two to seven years and can last for several months to several years.

During an El Niño event, the trade winds that normally blow from east to west across the Pacific weaken, which allows warm water to accumulate in the central and eastern Pacific. This warm water can cause changes in atmospheric circulation patterns, which in turn can lead to changes in weather patterns around the globe.

Unobtainium-146 has a half life of 5 years. Find the amount left from a 500 grak sample of unobtainium-146 after 15 years

Answers

There will be approximately 63.44 grams of unobtainium-146 left from the original 500-gram sample after 15 years.

To find the amount of unobtainium-146 left after 15 years, we need to use the radioactive decay formula:

N(t) = N₀e^(-λt)

Where:
N(t) = the amount of unobtainium-146 left after time t
N₀ = the initial amount of unobtainium-146 (in this case, 500 grams)
λ = the decay constant (which is equal to ln2/half-life)
t = time elapsed (in this case, 15 years)

First, we need to calculate the decay constant:

λ = ln2/t₁/₂
λ = ln2/5
λ = 0.1386 (rounded to four decimal places)

Now we can plug in the values:

N(15) = 500e^(-0.1386*15)
N(15) = 500e^(-2.079)
N(15) = 500*0.1269
N(15) = 63.44

Therefore, there will be approximately 63.44 grams of unobtainium-146 left from the original 500-gram sample after 15 years.

Ricin moves into a cell using active transport by binding to the ________ and ________ of the cell's membrane

Answers

Ricin moves into a cell using active transport, by binding to the proteins and lipids of the cell's membrane.

Active transport is a type of cellular process which requires the cell to expend energy, usually in the form of ATP molecules, to move molecules from a lower concentration to a higher concentration.

This is different from passive transport, which is the movement of molecules from a higher concentration to a lower concentration without the cell expending energy. In active transport, the proteins of the cell’s membrane act as a bridge for the ricin to cross the membrane.

The proteins bind with the ricin, and then the lipids of the cell’s membrane form a tunnel around the protein-ricin complex, allowing it to pass through the membrane. This process allows the ricin to enter the cell and allow it to carry out its deadly effects.

Within a population of butterflies, the color brown (B) is dominant over the color white (b). And, 40% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam, calculate the following:
The percentage of butterflies in the population that is heterozygous.
The frequency of homozygous dominant individuals.

Answers

If 40% of all butterflies are white (bb), then the remaining 60% of butterflies must be brown (BB or Bb).

Let p be the frequency of the dominant allele B, and q be the frequency of the recessive allele b.

We know that B is dominant over b, so the frequency of homozygous dominant individuals (BB) is p^2.

We also know that 40% of the population is white (bb), so q^2 = 0.4. Solving for q, we get q = 0.2.

Since p + q = 1, we can solve for p: p = 1 - q = 0.8.

The frequency of heterozygous individuals (Bb) is 2pq = 2(0.8)(0.2) = 0.32, or 32%.

The frequency of homozygous dominant individuals (BB) is p^2 = (0.8)^2 = 0.64, or 64%.

For the past 10 to 25 years, farmers have planted crop seeds that have been genetically modified to withstand treatment with a common weed killer called Roundup®. This allows the farmers to spray their fields to get rid of weeds without harming their crops. Recently, more and more farmers have discovered that their fields have Roundup-resistant pigweed growing along with their crop. Use what youâve learned in this activity to explain how this came about

Answers

The emergence of Roundup-resistant pigweed is a consequence of selective pressure on weed populations caused by the widespread use of genetically modified crops (GMO) that are tolerant to Roundup.

Over time, repeated applications of Roundup have favored the survival and reproduction of pigweed plants that possess natural genetic variations that confer resistance to the herbicide.

These resistant plants have passed on their resistant genes to their offspring, resulting in the emergence of a population of Roundup-resistant pigweed.

The extensive use of Roundup and the lack of alternative weed management strategies have further accelerated the spread of resistant pigweed, posing a challenge to farmers and threatening the sustainability of this agricultural practice.

A couple has two children with a genetic disease. what is the probability that the next child will have the same genetic disease

Answers

The probability of the next child having the same genetic disease depends on the inheritance pattern of the specific disease. If both parents carry a genetic mutation that causes a specific disease, then there is a chance that their children will inherit the same mutation and develop the same disease.


If the genetic disease is caused by a recessive mutation, then the probability of the next child having the same disease is 25% (1 in 4). This is because each parent carries one mutated copy of the gene but does not show any symptoms of the disease. When they have children, each child has a 25% chance of inheriting two copies of the mutated gene, one from each parent, and thus developing the disease.

If the genetic disease is caused by a dominant mutation, then the probability of the next child having the same disease is 50% (1 in 2). This is because only one copy of the mutated gene is needed to cause the disease, and each child has a 50% chance of inheriting the mutated gene from the affected parent.

It is important to note that these probabilities are not exact and can vary depending on other factors such as genetic testing and family history. Consultation with a genetic counselor can help provide more personalized information and guidance for families dealing with genetic diseases.

Why do ferns not grow as tall as gymnosperms and angiosperms?.

Answers

Ferns do not grow as tall as gymnosperms and angiosperms because they lack true vascular tissue and specialized support structures.

Vascular tissue, consisting of xylem and phloem, is responsible for transporting water and nutrients throughout the plant and providing structural support. Gymnosperms and angiosperms have evolved more efficient vascular tissue and specialized support structures such as lignified trunks, branches, and leaves, allowing them to grow taller and support more weight.

In contrast, ferns lack true vascular tissue and have a simpler structure that limits their ability to transport water and nutrients, as well as provide support. Ferns have underground stems called rhizomes that anchor the plant and absorb water and nutrients, but they are not as effective at supporting the plant's weight as the specialized structures found in gymnosperms and angiosperms.

Thus, ferns are typically smaller and grow closer to the ground, with few exceptions such as tree ferns, which have evolved specialized adaptations to support their height.

Answers

A substance produced by stomach cells that is needed for the absorption of vitamin B12 is intrinsic factor.

Intrinsic factor is a glycoprotein that is secreted by the parietal cells in the stomach lining. It plays a crucial role in the absorption of vitamin B12, which is necessary for the normal functioning of the nervous system and the production of red blood cells.

Vitamin B12 is found in animal products such as meat, fish, and dairy, and is bound to protein. In order for the body to absorb it, it must first be released from the protein by stomach acid and then bind to intrinsic factor, which is produced by the stomach cells.

The complex of vitamin B12 and intrinsic factor is then transported to the small intestine, where it is absorbed by the body.

Without intrinsic factor, vitamin B12 cannot be absorbed by the body, leading to a deficiency. This deficiency can result in a variety of symptoms, including anemia, fatigue, weakness, and nerve damage.

Intrinsic factor deficiency is most commonly seen in individuals with pernicious anemia, an autoimmune disease that affects the stomach lining and impairs the production of intrinsic factor.

Answers

The amount of snowfall a particular area receives depends on a variety of factors such as its geographical location, elevation, and proximity to large bodies of water.

Grand Rapids is located in the western part of Michigan, which is known to receive more snowfall than the eastern part, where Detroit is located. This is because of the lake-effect snow phenomenon, which occurs when cold air moves over the relatively warmer waters of Lake Michigan. The moisture from the lake evaporates and rises into the atmosphere, where it condenses and forms snow clouds.

These clouds then release snow as they move over the land, resulting in heavy snowfall in areas close to the lake. Grand Rapids is situated closer to Lake Michigan than Detroit, and therefore experiences more snowfall as compared to Detroit, which is farther away from the lake. Additionally, the elevation of Grand Rapids is higher than that of Detroit, which can also contribute to higher snowfall amounts.

What  did he find beautiful about the Apollo of Belvedere?

2. Winckelmann found the Apollo of Belvedere beautiful because it embodied many of the qualities he admired in Greek sculpture. The statue's idealized form, balanced proportions, and contrapposto pose conveyed a sense of harmony and perfection that Winckelmann believed was the essence of beauty. He also praised the statue's noble expression and confident gaze, which he saw as embodying the ideal of classical Greek masculinity.

3. The Apollo Belvedere and Mengs's painting of Apollo in Parnassus share several similarities, including their idealized depictions of the god Apollo, their use of classical motifs and references, and their emphasis on harmony, balance, and beauty. Both works also convey a sense of movement and energy, with Apollo shown in a dynamic pose that suggests motion and life.

4. In Mengs's painting of Parnassus, Apollo is shown in the company of other classical figures, including the muses and the god Bacchus, as he presides over the realm of poetry, music, and art. The painting is part of a larger decorative program for the Villa Albani in Rome, which was designed to celebrate classical culture and the arts. As such, Apollo's presence in the painting reflects his importance as a symbol of artistic inspiration and creativity in the classical tradition.
