For each of the following, circle the word that does not belong belong with the rest and then in ONE complete sentence, explain
Vika [28.1K]

Answer: the words that doesn't belong include:

1.) Power

2.) Deforestation

Explanation:

1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.

Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.

2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.

Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.

Knowing what we know about the link between genetics, environment and intelligence, what would be your expectations if you were
Vesnalui [34]

Answer:

I would expect them to perform similar.

Explanation:

Studies suggest that intelligence has a genetic component and can, in part, be passed from parent to child - but not only that. There are outer components that contribute to the formation of intelligent individuals. Better nutrition and more access to education would be possible explanations for the progressive increase in intelligence test scores over time.

Homozygous twins are those that are mainly characterized by similarity between individuals. These twins are formed from the same zygote, ie after the fertilization process. Because of this characteristic, they have the same genetic heritage and are therefore considered identical.

As the homozygous twins in their classroom have the same genetic heritage and attend the same environment, we can conclude that their intelligence is influenced by the same factors. For this reason, a teacher who taught these two brothers might have expectations that they would perform similarly in the classroom.
