Its a 50% chance that approx 1/2 of the pennies will land on tails. The next toss will result the same. and so on and so on. showing how a reaction would slowly eliminate 1/2 of the remaining lives per reaction, until nothing is left. I think it is a good stimulation.
Answer:
Stinging cell, nematocysts.
Explanation:
Corals have tentacles present near the oral opening. The tentacles comprise cells called stinging cells. These cells contain nematocysts used by corals to sting the prey and stun them using the tentacles. These stinging cells present near the mouth which contains nematocysts that is an organelle that produces toxic substances used by the coral to catch their prey.
The ocean of course! It is also very much unexplored and we have yet to find even a 1/4 of the organisms.
Answer:
The correct option is (a).
Explanation:
We need to find the product of given numbers.
First number = 29.5
Second number = 240
Product of two numbers = 29.5 × 240
=
Zeroes from numerator and denominator get cancelled.
So,
Hence, the correct option is (a).
Answer:
Hydrogen bond is a <em>special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and electronegative O,N or F atom</em>. The interaction is written:
A-B . . . B or A-H . . . .A
A and B represent O,N or F; A-H is one molecule or part of a molecule and B is a part of another molecule, and the dotted represents the hydrogen bond. So, hydrogen bond is a type of intermolecular forces (attractive forces between molecules, <u>NOT</u> between atoms of the same molecule), and only a few elements can participate on hydrogen bond formation.
<em>Note: dipole-dipole interactions are forces between polar molecules, that is, between molecules that possess dipole moments. </em>
