Answer:
The correct representation is attached with the explanation.
Explanation:
In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
Answer:
This conversion of one form of energy to another is called energy transformation.
Explanation:
Eye is one of the most important sensory organ of our body that helps in the perception of light.
When we see a light at that time light energy is converted into neural messages and then carried to the brain by ophthalmic nerve for processing.
Here the law of conservation of energy is maintained which states that energy cannot be created nor destroyed, energy can only be transformed.
Answer:
A. 4 right handed coil:0, left- handed coil
Explanation:
According to MENDELION CROSS:
We will get NN, Nn,Nn,nn
NN, Nn, Nn are the 3 right handed coiling and nn is left handed coiling.
But in case of shell coiling in snails, maternal inheritance is applied in which offspring is decided only by phenotype.
Maternal traits: Here,female parent has right handed shell coiling. so, all the offsprings will have the same.
Hence, the phenotypic ratio will be:
4 Right handed coil: 0 Left handed coil
No matter what the cell type, prokaryotic or eukaryotic, plant or animal, the cell membrane forms a protective barrier between the exterior environment and the interior of the cell.
<u>Answer</u>: Thermal energy----> a polar bear breaks down stored fat to increase its temperature.
Mechanical energy-------> bat emits and receives sounds to locate prey.
Electrical energy------>eel releases a current to defend itself.
Radiant energy --------> a firefly produces a green glow from its abdomen to attract mates.
<u>Explanation</u>:
- <em>Thermal energy</em> is the energy created in the movement of particles that leads to the production of heat and thus, the temperature increases. Since the polar bears break down fat to increase temperature, the energy generated is thermal energy.
- The<em> mechanical energy</em> is defined as the sum of energy of motion and the position of an object . Thus the energy produced by the bat to locate its prey is mechanical energy.
- The energy associated with the production of electromagnetic radiation is<em> radiant energy,</em> thus the glow produced by fireflies is a form of radiant energy.
- The energy produced due to the movement of electrons is electrical energy. Thus, the energy produced by an eel in the form of electric current is <em>electrical energy.</em>
