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:
The correct answer is : temperature.
Explanation:
Siamese cats are known and characterized on the basis of the regions that are light or dark on the part of the body of these cats as according the cooler part of the body.
It is influenced by the enzyme that is active due to low temperature that leads to the formation of the dark pigment in the cooler area and in the part of the body that are higher in temperature are lighter due to inactivity of the enzyme.
Thus, the correct answer is : temperature.
Phytoplankton serves as food for virtually all the organisms living in an aquatic environment. It is a primary food producer and serves as the foundation of aquatic food web. If there is a decline in the amount of phytoplankton, the organisms which feed directly on the plant may reduce significantly as a result of dire competition for food, this in turn will affect the organisms which feed on the dying out organisms and the trend will move in a similar way until it affect all the organisms living in that particular aquatic habitat.
