Answer:
This question is incomplete as it lacks options, however, it will be answered BROADLY so the it can be understood enough to select the correct answer.
Please find the explanation below
Explanation:
Cells perform different functions and look differently because of the process of CELL DIFFERENTIATION. All cells arise from a single stem cell, which then gradually differentiates into different types of cells with different functions, as they divide.
At the molecular level, these different types of cells contain the same DNA sequence as rightly stated in the question. However, they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION.
Therefore, a blood cell and skin cell possess exactly the same DNA sequence but look different and perform different functions because of CELL DIFFERENTIATION in which some genes on the DNA sequence are expressed and others are repressed. For example, in the blood cell; the genes coding for certain proteins found in blood are expressed while every other gene is silenced or inhibited. This allows those cells to perform only blood-related functions.
Answer: A focal spot in the x-ray setup is the area of the anode surface which receives the beam of electrons from the cathode. It is the apparent source of x-rays.
Below are some of the factors that affect its size.
Explanation:
Size of the focal spot depends on
* angle of the anode
Other prime factors that affect x-ray emission; under the control of the radiographer includes;
• Miliamperage-second (mAs)(tube current measurement)
• Kilovoltage (kVp) Controls both the quantity and quality of the x-ray beam with the speed and energy.
• Distance (d) - Related to tube design and construction.
• Tube housing
• Target material
• Filtration
• Voltage waveform

Answer:D. tapeworms live inside a goats body in a close relationship the goat.
Explanation:
In parasitic relationships,the parasite lives on the host and benefits from the host while causing harm to the host .the host does not benefit.the parasites are usually in close relationship with their host as their food source are substances of the host organisms.
The parasite may live in the host , these are called Endo-parasites.
The parasite may live outside the host, these are called ecto-parasite. In this example, the tapeworm is an endo-parasite that lives in the digestive tract of the goat. It absorbs digested food in the intestine through it's body surface.
In predator and prey relationship, the predator usually has to hunt for the prey and feed on it. It may kill it first or may not
