Chemical<span> reactions like the one above contain two parts: The reactants and the products. 2. Products—the substances that are produced by the reaction. B. Energy in Reactions—energy is </span>released or absorbed whenever chemical bonds form or are broken<span>. :)</span>
Water exists as a solid at or below 0 degree Celsius.
At 0 degree Celsius, water can go through a phase change, either freezing or melting, depending whether energy is given or taken away. If the temperature is below 0, water should exist as solid as the temperature is lower than its melting point. If the temperature is right at 0 degree, the water can partially be solid and liquid at the same time, during phase change.
Therefore, water exists as solid at or below 0 degree Celsius.
Answer:
they carry the genetic info in the form of genes
Explanation:
Chromosomes carry the genetic information in the form of genes. They are a threadlike structure of nucleic acids and proteins, and are found in the nucleus of most living cells.
For example bees they use wax to build shelter
Answer:
Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.
Explanation:
The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!
