Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
Answer:
Simple answer, yes.
Explanation:
Monocots have isobilateral leaf I.e both sides of the leaf are equally exposed to the sun.
Dicots have dorsiventral leaf I.e. ventral side is exposed to the sun more than the dorsal side.
They are very distinctly different from each other and can be separated easily, and so are their roots.
The organelle that maintains pressure against the cell wall, so that the plant cell keeps it shape, is
the (a) central vacuole.
Answer:
a. are a valid way to measure a person's inborn intelligence
Explanation:
IQ testing is an important tool for measuring an individual's innate intellectual abilities, as long as its content is not limited to just one area of knowledge. Cognitive ability is related to hereditary and cultural characteristics that can be inherited or developed throughout life. Over the years, experts have developed techniques for measuring individual intellect.
The tool is used to obtain an intelligence indicator for different purposes. Following the original idea of the test, its application may be necessary to identify children with attention deficit or who are in a more advanced learning process than other students.
The IQ test is also used to diagnose issues related to an individual's behavior and conduct, and to support a job selection process.
