4. Which event would be the most predictable one year in advance of the event?
Black_prince [1.1K]

Answer:

1. an eclipse of the Sun

2. state (phase) of matter

3. 5.0 g/cm3

Explanation:

1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.

2. Considering the following groups: Group A: water, aluminum, water vapor

Group B: gasoline, ice, air

Group C: alcohol, iron, oxygen

One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.

This shows that the STATE (PHASE) OF MATTER was the basis of classification.

What does natural selection favor?​
ratelena [41]

Answer:

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

The reason that natural selection is important is that it's the central idea, stemming from Charles Darwin and Alfred Russel Wallace, that explains design in nature. It is the one process that is responsible for the evolution of adaptations of organisms to their environment.

Explanation:

hope this helps
