Answer:
Water carries several physical properties such as chemical formula, appearance, boiling point, freezing point, density, viscosity and solvency.
An increase in temperature changes the density of water. When a water is heated or its temperature is allowed to increase it causes the water molecules to gain energy and move faster, which results in increase in water volume due to movement of water molecule far from each other. on the other side if temperature of water is decrease, it's molecules come closer to each other and decrease in the volume of water takes place.
Answer:
The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. ... 6,331 groups of genes common to all living animals have been identified; these may have arisen from a single common ancestor that lived 650 million years ago in the Precambrian.
Answer:
Well The answer you choose was wrong I think because every living being that has cells need a Nulceus in their cells or the cells won’t work. Fungi have cells and Protista also have a nucleus since it has a cell or cells.
The answer here I would think would be (c) ”many could be found in fresh water”. Fungi don’t usually appear near seas or fresh sources which in this case is a pond and protistia do.
The nurses are wrong because first of all brown is a dominant eye color while blur is the recessive one. So the blue-eyed baby has to belong with the couple who both have blue eyes, while the brown-eyed baby has to belong to the couple that one parent has blue eyes and the other has brown eyes.
Yes it is alive . It respires , photosynthesizes and grows . It reacts to stimuli ( sunlight ) and tries to survive by adapting to the environment . Its' billions of cells form into transport vessels , roots , leaves and other structures to facilitate the creation and use of energy .
