Because there's more space between the molecules, a volume of hot water has fewer molecules in it and weighs a little bit less than the same volume of cold water. So hot water is less dense than cold water which allows it to layer on top
Answer:
Caulobacter crescentus is a specie of gram negative aquatic bacteria. There is gene called as Ccrm gene in them that is responsible for the the synthesis of Ccrm enzyme that is crucial for the proper cell division of cells. When, there is a mutation in this gene, the bacteria won't be able to synthesize Ccrm enzyme anymore. This causes accumulation of two conserved FtsZ and MipZ proteins in cells and result in severe defects and irregulations during cell division.
Plants help the environment (and us!) in many different ways:
plants make food
plants make oxygen
plants provide habitats for animals
plants help make and preserve soil
plants provide useful products for people
plants beautify

Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
