An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water.
The Gerobatrachus hottoni is most likely to be a phylogenic fossil.
Answer:
Transgenic bacteria can be described as bacteria which have a foreign gene inserted into their genome. The genetically modified bacteria are helpful to humans in a number of ways. Some of these are:
- Production of human proteins especially for medicines.
- Production of herbicide and pesticide resistant genes so that the crop production is enhanced.
- transgenic bacteria are used for bioremediation as they break down contaminants.
- For producing amino acids which benefit the humans.
Answer:
The change of fur color within the population over time became black as a result of the lava flow and allowed the mice to survive.
Explanation:
Because the mice that have brown fur would stand out and get picked of by predators so over time the mice with the darker fur could hide more easy and spread there genetics more easily.

belongs to the genus Pomacea, Ampullariidae
family. This family is also often called Apple Snail, and it contains a nearly
120 different species of snails. I know that increase in the number of black
snails can best be explained by the high teperature in which black snails are.
It's the main reason of their reproduction.</span>
