Answer:
The correct answer is - biological hierarchy.
Explanation:
Biological hierarchy can be understand as the comprehension of the simplest form of the life to the most broadest and complex form of the life. It includes from the atoms which is a smallest structure and cells to the interactions of in between non living things and living things.
The broadest or highest level of the organization is biosphere in biological hierarchy in includes all other living organisms with non living things present in it. atoms to cell, tissue, organ, organ system to organism. these organisms shows interaction with each other and called populations that form communities, to ecosystem and finally biosphere.
Thus, the correct answer is - biological hierarchy.
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:
<em>The genotype of the mother will be Bb.</em>
Explanation:
A punnet square can be described as a diagram which is made to depict the outcome of a cross.
In the scenario discussed in the question, the genotype of the male parent will be bY. This is because he has the recessive black spots. As he is a male, he'll only have one allele for this gene.
In order to have one of spot design for each gender, the mother will have the genotype Bb.
The punnet square will be as follows:
b Y
B Bb BY
b bb bY
The answer is cornea…..lens. Most bending of light entering
the eye is bent by the cornea. The lens of the other hand adjusts this bending
further, to focus it squarely on the retina. This is why the focal point of the
lens can be adjusted by changing its shape.
