If  nancy has $240 in the bank. she wants to buys as many $15 video games as possible. The number of video games she can buy if she wants to save $120in the bank is 8.

To determine how many video games Nancy can buy while still saving $120 in the bank, we need to subtract the cost of the video games from her original amount and then subtract the desired savings.

First, let's calculate the total cost of the video games:

$15 per video game * number of video games = total cost

Next, we subtract the total cost from Nancy's original amount:

$240 - total cost = remaining amount

Finally, we compare the remaining amount with Nancy's desired savings:

remaining amount = $120

So we can set up an equation to solve for the number of video games:

$15 * number of video games = $240 - $120

$15 * number of video games = $120

number of video games = $120 / $15

number of video games = 8

Therefore, Nancy can buy 8 video games and still have $120 in the bank.

Because Nancy can buy 8 video games and still have $120 in the bank, the inequality is 8 ≤ $120 left in the bank.

How did I get this answer?

240-120 (for her bank) then you'll be left with 120. You can then divide 120 by 15 and get 8. Thus, Nancy can buy 8 video games.

Answer:

Dyspahgia and alcohol are related.Past years of alcohol(besides medication for asthma,sedatives,antidepressants) intake may  trigger  the transformation of some of the cells lining the oesophagus. The oesophagus  is  lined with stratified epithelial  cells. Persistent alcohol intake may lead to  transformation these cells to abnormal cell of  columnar epithelial.They are known as Dysplasia

The dysplasia  in the patients  leads to Barrett's esophagus.These Columnar cells makes the oesophagus of TS prone to  esophageal adenocarcinoma .The dysplasia  may lead to tumour,and therefore  obstruction of the oesophagus.This may therefore account for  the Dysphagia experienced by TS,Hence peristalsis is inhibited and soild foods can  not be moved down,

2.The state of the medication should be liquid. Because of  the difficulty in swallowing,which  will not allow the medication to reach stomach,for absorption.Intravenous administration can also be adopted.

3. Dysphagia,burning sensation due to acid reflex , pain in the chest and upper abdominal part ,tendencies to regurgitate foods,bad breath, are some of the symptoms of Gastroestro esophageal reflux,

Through the process of natural selection, sea urchins have developed spines that serve as a defense mechanism against predators and a means of anchoring themselves in turbulent waters. This adaptation allows them to better survive in their environment, with individuals possessing longer or stronger spines being more likely to pass on their genes to the next generation. As a result, the population of sea urchins gradually becomes better adapted to their surroundings, demonstrating the power of natural selection in shaping the evolution of species.

The difference between the gene expression between human fibroblasts and induced pluripotent stem cells are defined below.

Gene expression refers to the process by which the information that is encoded in the DNA is used to produce functional gene products such as RNA and proteins.

Human fibroblasts are a type of connective tissue cell that play a key role in wound healing and tissue repair. They have more specialized and differentiated gene expression than the induced pluripotent cells because they have already undergone a significant amount of differentiation and have taken on specific functional roles on the tissues.

Induced-pleuripotent cells have less specialized gene expression, where the expression of pluripotent- associated genes and lack of tissue-specific genes.

Through the process of mutation, new genes are inserted into a population's gene pool.

Within a species, structural physiological changes take a long time to manifest. These changes appear to be the product of the natural selection of favorable traits within that species. The idea of evolution is best encapsulated in these phrases.

The emergence of new species and groupings is an example of macroevolution, which is the term used to describe significant changes that take place over long periods of time. Small-scale adjustments that have a limited impact on a few genes and occur in populations over shorter time periods are referred to as microevolution.

Explanation:

When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:

1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.

2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.

3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.

4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.

5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.

6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.

Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

Some causes of the background are; Gradual environmental change, Predation, Genetics, and causes of mass extinction are; Catastrophic events, environmental change, Oceanic changes, and Human activities.

Causes of background extinction; Changes in the environment, such as climate change or geological events, can cause slow, long-term changes that make certain species less adapted to their environment.

The introduction of new predators or changes in predator-prey relationships can also lead to the extinction of some species.

Genetic factors can play a role in the extinction of species, particularly in small populations where genetic diversity is low.

Causes of mass extinction; Mass extinctions can be caused by catastrophic events, such as asteroid impacts, massive volcanic eruptions, or global climate change.

Rapid changes in the environment, such as sudden climate change or sea level change, can cause species to become extinct.

Changes in the ocean, such as ocean acidification or anoxia, can lead to the extinction of marine species.

Human activities such as overhunting, habitat destruction, pollution, and introduction of invasive species can also contribute to mass extinction events.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.
