Answer:
Cell
Explanation:
They are the 'building blocks' of life and make up organisms.
Answer:
The correct answer will be option-A
Explanation:
Chromosomal abnormalities are caused when the chromosome pair fails to disintegrate through a process called non-disjunction. The non-disjunction of chromosomes usually takes place at the anaphase I or II of meiosis I which involves the X and Y chromosomes.
The abnormality observed with 45 chromosomes or reduction in one sex chromosome or 45, XO is caused when one X copy of a chromosome is completely absent in the cell.
The cause for the loss of one chromosome is the non-disjunction during meiosis I.
Thus, option-A is the correct answer.
Transparent means all light can shine through. Common substances that are transparent are clear glass, clean water, and cellophane. Translucent means only some light can filter through the substance. Common translucent substances are tissue paper, the skin of your hand, and lamp shades. Opaque means little to no light passes through the substance. Common opaque substances are denim, cardboard, and leather.

A. It acknowledges the correct amount of decimal points and could be a reasonable measurement.
B is incorrect because we don’t have measurements down to the hundredth place on the ruler.
C is incorrect because it doesn’t acknowledge the amount of decimal places available, only stating it as a whole number.
D is incorrect for the same reason as C.
The given case is an example of reflex action.
The reflex action is an instant involuntary response to a stimuli, which can cause damage. The reflex action takes place through the processing of message through a reflex arc, this reflex arc lack the involvement of brain and the processing of the stimulus takes place in the spinal cord.
In this case, the sensory receptors detects the stimuli and transfer the message to the relay neuron present in the spinal cord through the sensory neuron. The relay neuron transfer the action message to the effector muscles present at the site of stimulus with the help of motor neurons.
Given below is a block diagram of reflex action.
