Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.

Please put this question in English and I would then love to help you. Thanks.
The above is an example of a polygenic trait. This implies every prevailing allele "includes" to the declaration of the following predominant allele. As a rule, qualities are polygenic when there is a wide variety in the characteristic. For instance, people can be a wide range of sizes. Stature is a polygenic characteristic, controlled by no less than three qualities with six alleles.
Explanation:
The rate of photosynthesis increases withe increase in temperature. Photosynthesis like any other chemical reaction responds positively to an increase in temperature.
At high temperatures, enzymes that takes part in the photosynthesis can be destroyed. This is 20°C where enzymes are usually denatured.
- Photosynthesis is the process where green plants manufacture their food using inorganic substances from the environment.
- During photosynthesis, plants combines carbon dioxide with water and produces organic molecules and oxygen.
- Like any other chemical reaction, the reaction will proceed faster with an increase in temperature.
Hypothesis: If temperature is increased then the rate of evolution of oxygen gas increases because the rate of chemical reactions increases with increase in temperature.
Since oxygen is a by product of photosynthesis, we can quantify its rate of production as temperature increases.
