The question asks about the tissue responsible for the increase in girth (thickness) of a plant stem or root. This refers to secondary growth, which is the increase in diameter, as opposed to primary growth, which is the increase in length. We need to identify the type of meristematic tissue responsible for this lateral growth.
A) Lateral meristem — Lateral meristems, such as the vascular cambium and cork cambium, are responsible for increasing the diameter or girth of the stem and root. This process is known as secondary growth.
The question asks for the country that hosted the world's first robot ski competition. This is a factual recall question related to technological advancements and international events.
Correct Option: C) South Korea
The world's first robot ski competition, the "Ski Robot Challenge," was held in South Korea in February 2018. Eight teams from various South Korean universities and research institutes participated, showcasing their autonomous ski robots on a downhill course with flags.
The problem asks for the ratio of linear momenta of two bodies given their masses and that they have equal kinetic energy. We need to use the relationship between kinetic energy, mass, and linear momentum to solve this.
A) 1 : 3 is the correct ratio derived from the relationship between kinetic energy, momentum, and mass.
Select the mirror image of the following figure.
To find the mirror image of a given figure, we need to reflect it across a vertical axis. This involves flipping the figure horizontally, so that the left and right sides are swapped.
Correct Option: C) Option C is the correct mirror image of the original figure.
If in a certain code language, PLANT is coded as QMBOU, then in that code language what will be the code for TOYOTA?
The problem is a coding-decoding question. We need to identify the pattern used to code "PLANT" as "QMBOU" and then apply the same pattern to decode "TOYOTA".
The pattern is consistently adding 1 to the alphabetical position of each letter.
B) UPZPUB is the correct code derived by applying the "next letter" pattern to each letter of TOYOTA.
To determine which number has a rational square root, we need to identify which of the given numbers is a perfect square. A number has a rational square root if and only if it is a perfect square. We can check this by looking at the last digit of the numbers and, if necessary, by using the long division method or prime factorization to find the square root.
B) \(34225\) has a square root of \(185\), which is a rational number.
This question tests understanding of basic directions and their opposites. We need to identify the direction opposite to South-West.
Correct Option: D) North-East
An object moves in a straight line when the machine provides continuous power. The distance traveled by the object in time 't' will be proportional to _______.
\( t^{\frac{3}{4}} \)
\( t^{\frac{1}{2}} \)
\( t^{\frac{3}{2}} \)
\( t^{\frac{1}{4}} \)
The problem states that an object moves in a straight line with continuous power supplied by a machine. We need to find how the distance traveled by the object depends on time. We will use the definitions of power, force, acceleration, and equations of motion.
Correct Option: C) \( t^{\frac{3}{2}} \)
Find the odd diagram.
The task is to identify the diagram that does not belong with the others based on a common characteristic.
Correct Option: B) The cube is the only 3D shape among 2D figures.
The question asks for the specific term that describes an atom's tendency to attract electrons when it is part of a chemical bond with another atom. We need to identify the correct chemical concept from the given options.
A) Electronegativity is the precise term used to describe the relative tendency of an atom to attract electrons when it is bound to another atom. It is a crucial concept for understanding chemical bonding and molecular properties.
