If we stopped burning fossil fuels today, what would happen to the climate?.
If we stopped burning fossil fuels, the climate would be much cooler than it is today. The hot planet is a big concern today.
What is fossil fuel?Fossil fuels are matter that is made up of decaying organic matter, such as animals and plants. Fossil fuels are made for millions of years. They are used in running big machines and generating power plants.
Fossil fuels are burned in running machines or run a car, and the gases that came from this burning cause the earth to warm.
Thus, the temperature would be significantly colder than it is right now if we stopped burning fossil fuels. Today, the planet's heat is a major problem.

There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time.
1. Identify a type of variation in the worms.
2. Which variation is most favorable?
3. In 50 years, what will natural selection have most likely done for the worms? (Hint: What type of worm will be the most common. )
4. What adaptations might occur in the birds in 100 years?
We can confirm that one variation in the worms is the adaptation to become nocturnal eaters instead of the more dangerous diurnal eaters.
Why are nocturnal worms favored?Nocturnal worms are favored over diurnal eating worms given that the main predator of worms, birds, hunt during the day. This puts the diurnal worms are a much higher risk of being consumed. Through natural selection, this will likely result in most worms being entirely nocturnal within the next 50 or so years, which can in turn lead to the evolution of more nocturnal hunting bird species.
Therefore, we can confirm that one variation in the worms is the adaptation to become nocturnal eaters instead of the more dangerous diurnal eaters, which will likely be the most common variation over time, due to natural selection.

What type of substance was added to the water (Substance A), and what new substance was produced (Substance B)?
A) Substance A is a base.
Substance B is a group of hydroxide ions.
B) Substance A is an acid.
Substance B is a group of hydronium ions.
C) Substance A is an acid.
Substance B is a group of hydroxide ions.
D) Substance A is a base.
Substance B is a group of hydronium ions
Answer:
Substance B is a group of hydroxide ions.
Explanation:
According to the concept of acid and base substance A is an acid while substance B is a group of hydroxide ions.
What is an acid?Acids are defined as substances which on dissociation yield H+ ions , and these substances are sour in taste. Compounds HCl, H₂SO₄ and HNO₃ are acids as they yield H+ ions on dissociation.
According to the number of H+ ions which are generated on dissociation acids are classified as mono-protic , di-protic ,tri-protic and polyprotic acids depending on the number of protons which are liberated on dissociation.
Acids are widely used in industries for production of fertilizers, detergents batteries and dyes.They are used in chemical industries for production of chemical compounds like salts which are produced by neutralization reactions.

The evolution of similar forms in different lineages when exposed to the same selective pressures is.
The evolution of similar forms in different lineages when exposed to the same selective pressures is convergent evolution.
Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.
What is convergent evolution?
Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.
Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.
Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.
