The answer is D, patient's diet.
Explanation:
As per the observation, it is clear that the correct answer is a medical book as it will have the medical history of the patient.
Gigantism is an extreme situation this is almost usually due to an adenoma, a tumor of the pituitary gland. Gigantism happens in sufferers who had immoderate boom hormones in childhood. The pituitary tumor cells secrete an excessive amount of boom hormone (GH), which main to many adjustments withinside the body.
How is gigantism diagnosed?If gigantism is suspected, the prognosis is commonly shown via way of means of taking blood assessments to degree the stages of boom hormone and insulin-like boom component 1 (IGF1) circulating withinside the blood. IGF1 is launched into the blood often via way of means of the liver in reaction to boom hormone.

Bromine is a liquid at room temperature. The volume of a sample of bromine is measured in a 50 ml beaker and a 100 ml beaker. How will the two
measurements compare?
A. The volume of bromine will be larger in the 100ml beaker.
B. The volume of bromine will be smaller in the 50ml beaker,
C. The volumes will be the same.
D. Both A and B
The actual volume of bromine in each beaker will be same only the difference in height will be comparable. Therefore, option (C) is correct.
What are the properties of liquid ?A liquid's attributes are;
1) Compared to the volume occupied by a gas, the volume of a liquid is relatively stable at conditions that allow it to remain in the liquid state.
2) A liquid will take the form of the container it is placed in.
3) A liquid's surface in a container must be flat for the attraction forces between its molecules to be in equilibrium both at the liquid's surface and within its body.
Therefore, there will be variations in the measured height of the same volume of bromine in each beaker given that the volume of the bromine is measured in a 50 ml beaker and a 100 ml beaker.

What is treatment of cancer?
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 often divide (via a process known as cell growth and multiplication) to create new cells as the body requires them.
Occasionally, this systematic process fails, causing damaged or aberrant cells to proliferate when they shouldn't. Tumors, which are tissue masses, can develop from these cells. Tumors may or may not be cancerous.
Therefore, Removal by surger and treatment with high-energy radiation.

Answer:
16. Control group: Subject A
17. Independent (manipulated) variable: Type of powder
18. Dependent variable: Itching time
19. Explain whether the data supports the advertisement´s claims about its product. Yes, it does.
Explanation:
Control group: The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study (in this case, the new product), from the results that might be a consequence of other factors. The control group must be selected from the same population as the treatment group. Data from an experimental group are compared with the data from a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups. In this case, the experimental group is subject B.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the type of powder is the independent variable. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, inching time is the dependent variable, that depends on the type of powder used. The data does support the advertisement´s claims about its product. The effect of the new product lasts 50% more than the original product. The old powder produced itching for 30 minutes, while the new product produced itching for 45min (15 more minutes, 50% more).When making a Punnett square the alleles of the mother and father are written at the top and side of the four square box.

List and explain the 3 paths natural selection can take.
Answer:
1. Stabilizing Selection
2. Directional Selection
3. Disruptive Selection
Explanation:
Stabilizing Selection
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed:
Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
Directional Selection
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side:
Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
Disruptive Selection
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such:
Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

Why is genetic diversity higher in big cities than in small towns?
Answer:
cities are more likely to have a population of people from other places while small town don't really have a Flux of population so it stays smaller
There is a genetic diversity higher in the big cities than in small towns because of the diversity of population that is present in it. The diversity brings out the different type of population in them.
What are the various factors that determine the population as well ?These are the availability of resources with the type of temperature and the environment that are determined in order to see the type of population present in it.
Genetic diversity is just influenced by the population size along with the with smaller populations that are having an increased probability of the inbreeding with the genetic drift and potential fixation of the deleterious types of alleles which just decreases the genetic diversity along with the adaptive potential.
Higher population of the genetic diversity that is in abundant species that is likely happening due to the combination of the demographic factors that are including the larger types of the local population that are in sizes with the faster generation times along with the high rates of the gene flow with the other type of populations.

A. deciduous trees
B. grasses
C. small shrubs
D. cone-bearing trees
Answer:
Small Shrubs
Explanation:
They Give off energy that makes them dominate the coniferous forest biome
The dominant plant life in the coniferous forest biome are cone-bearing trees, also known as conifers.
What is a coniferous forest biome?Coniferous forests are found in areas with cool, moist climates, such as the taiga regions of North America, Europe, and Asia. These forests are characterized by their dense stands of evergreen trees that are adapted to the long, cold winters and short growing seasons of their native habitats. The most common types of conifers in these forests include species of pine, spruce, and fir.
Conifers are easily recognizable by their distinctive needle-like leaves and reproductive structures, which are cones that contain the seeds. These adaptations allow conifers to conserve water, resist cold temperatures, and reproduce efficiently, making them well suited to the harsh conditions of the coniferous forest biome.
In contrast, deciduous trees, grasses, and small shrubs are more commonly found in other biomes, such as deciduous forests and grasslands.

Priscilla was building a circuit that used copper wires to connect a battery to a light bulb. As she connected the final wire from the light bulb back to the battery, the light bulb turned on. Priscilla knew that current was now flowing through her closed circuit. What makes the current in the circuit flow?
Answer:
The complete path provided by the closed circuit enables electric current produced by the battery to flow round the circuit
Explanation:
Electric current consists of charges (electrons) in motion from one region to another.
An electrical circuit is any closed path through which electric current can flow.
An electrical circuit consists of an energy source that supplies the electrons moving, a path along which the electrons can travel, and a load or appliance that uses the electrical energy. When the circuit is broken at any point, electrons will cease to flow since there is no complete path for it to flow. Such a circuit is known as an open circuit.
In the circuit built by Priscilla, the battery serves as a source of energy by providing the electrons that moves round the circuit. The wires provides the path for electrons to flow from the battery through the light bulb and back to the battery. When she connected the final wire from the bulb back to the battery, the circuit becomes complete/closed and current then flows to light up the bulb.
