What is the most valuable mineral in your phone?

Answer:

Explanation:

(a) The two variables being compared are the occurrence of accidents (drivers with accidents vs. controls) and the infection status with Toxoplasma gondii (infected vs. uninfected). In this case, the explanatory variable is the infection status with Toxoplasma gondii, and the response variable is the occurrence of accidents.

(b) To depict the data in a graph, we can create a 2x2 contingency table or a bar chart. Since the data is already provided in a 2x2 table format, we can use a bar chart to visualize the comparison between the variables.

markdown

                       | Infected | Uninfected |

------------------------------------------------

Drivers with accidents  |    21    |     38     |

Controls                |    38    |    211     |

In the bar chart, we would have two bars representing the occurrence of accidents: one for drivers with accidents and one for controls. Each bar would be divided into two sections representing the infection status: infected and uninfected.

To determine if the two variables are associated in this dataset, we need to assess if there is a difference in the distribution of infection status between the drivers with accidents and the controls. If there is a notable difference, it suggests an association between the variables.

The problem is comparing whether being infected with Toxoplasma gondii influences involvement in car accidents. An explanatory graph can be created and a statistical analysis such as chi-square test can give a more accurate inference on the association between these two variables.

(a) The two variables being compared in this problem are 'status of being infected with Toxoplasma gondii' and 'involvement in car accidents'. Here, the explanatory variable is 'status of being infected with Toxoplasma gondii' because we are examining its effect on the response variable, 'involvement in car accidents'.

(b) For depicting the data in a graph, one could create a bar graph with two variables 'Infected' and 'Uninfected', represented along the horizontal x-axis. The vertical y-axis could represent the quantity of people from the two groups: 'Drivers with accidents' and 'Controls'.

If the bar of 'Infected' drivers with accidents is significantly higher than 'Infected' controls, then we can say these two variables are associated in this data set. Otherwise, the association is not significant. To be sure, a statistical test such as chi-square test would provide a more definitive answer.

Answer:

Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.

Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.

Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.

The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.

Answer:

ringworms are fungis

they transmit viruses and bacteria to humans

Answer:

C. They are biotic

Explanation:

Fungi are not plants. Living things are organized for study into large, basic groups called kingdoms. Fungi were listed in the Plant Kingdom for many years. Then scientists learned that fungi show a closer relation to animals, but are unique and separate life forms.

I am not sure about the second option but I would say that it is also A. Ringworm is fungi

Ringworm is a common infection of the skin and nails that are caused by fungus. The infection is called “ringworm” because it can cause an itchy, red, circular rash. Ringworm is also called “tinea” or “dermatophytosis.” The different types of ringworm are usually named for the location of the infection on the body.

What I can conclude about ringworm is that a type of fungus causes them but I am not sure that they are classified as one too.

To calculate the amount of valine required to grow 1 gram of the bacterium, we can use the following steps:

Determine the total amount of protein in 1 gram of the bacterium. Since protein makes up about 50% of the bacterial cell, this would be 0.5 grams.

Calculate the amount of valine in 0.5 grams of protein. Since valine constitutes approximately 4% of the total cell protein, this would be:

0.5 grams protein x 0.04 (fraction of protein that is valine) = 0.02 grams valine

Convert the amount of valine to milligrams (mg) by multiplying by 1000:

0.02 grams valine x 1000 = 20 mg valine

Therefore, approximately 20 mg of valine should be added to the defined medium to grow 1 gram of the bacterium.

Explanation:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

During the first few seconds of intense exercise, our body produces energy through the breakdown of ATP (adenosine triphosphate) molecules stored in the muscles.

Our body produces energy during the first few seconds of intense exercise through a process called anaerobic metabolism, which relies on stored ATP (adenosine triphosphate) and creatine phosphate. This allows for rapid energy production, enabling our muscles to perform high-intensity activities. ATP is the primary source of energy for muscle contraction, and when it is broken down, it releases energy that is used to fuel muscle movement.

However, the supply of ATP is limited, and it is quickly depleted during intense exercise. To continue producing energy, the body switches to other energy systems, such as anaerobic glycolysis and aerobic metabolism, which can produce energy for longer periods of time but at a slower rate.

Internal stimuli are biological responses of the human body to its own physical conditions. The human body is perpetually in a state of homeostasis, and physiological systems are continuously adjusting to maintain this balance. Internal stimuli include hunger, thirst, and changes in blood pressure, heart rate, and body temperature.

In response to these stimuli, the body reacts to restore balance.When it comes to internal stimuli, "tasting something sweet" is not an appropriate response. Tasting something sweet is a response to external stimuli. When you put something sweet in your mouth, your taste buds send a message to the brain, which perceives the sweet taste. This perception triggers a series of physiological responses, including the release of insulin to process the sugar in the food.Internal stimuli, on the other hand, are the responses to changes in bodily functions or to changes in the environment of the body.

These include hunger, thirst, and changes in blood pressure, heart rate, and body temperature. In response to these stimuli, the body reacts to restore balance. These responses can include changes in heart rate, breathing rate, sweating, or shivering.

Aneuploidy is a common characteristic of cancer cells, which often have complicated karyotypes with both structural and numerical alterations. therefore, option e is the right choice.

Cancer is a condition when a few of the body's cells grow out of control and spread to other bodily regions.

In the millions of cells that make up the human body, cancer can develop practically anywhere. Human cells typically expand and divide to create new cells as the body requires them. New cells replace old ones when they die as a result of ageing or damage.

Proto-oncogenes, tumour suppressor genes, and DNA repair genes are the three primary gene groups that are typically impacted by the genetic alterations that cause cancer. These modifications are commonly referred to as cancer's "drivers."

Genes that decrease tumours are also involved in regulating cell division and proliferation. Certain tumour suppressor gene mutations can cause cells to divide uncontrollably.
